specifications gal16v8 4 the following discussion pertains to configuring the output logic macrocell. it should be noted that actual implementation is accom- plished by development software/hardware and is completely trans- parent to the user. there are three global olmc configuration modes possible: simple , complex , and registered . details of each of these modes are illustrated in the following pages. two global bits, syn and ac0, control the mode configuration for all macrocells. the xor bit of each macrocell controls the polarity of the output in any of the three modes, while the ac1 bit of each of the macrocells controls the input/output configuration. these two global and 16 individ- ual architecture bits define all possible configurations in a gal16v8 . the information given on these architecture bits is only to give a better understanding of the device. compiler software will trans- parently set these architecture bits from the pin definitions, so the user should not need to directly manipulate these architecture bits. the following is a list of the pal architectures that the gal16v8 can emulate. it also shows the olmc mode under which the gal16v8 emulates the pal architecture. pal architectures gal16v8 emulated by gal16v8 global olmc mode 16r8 registered 16r6 registered 16r4 registered 16rp8 registered 16rp6 registered 16rp4 registered 16l8 complex 16h8 complex 16p8 complex 10l8 simple 12l6 simple 14l4 simple 16l2 simple 10h8 simple 12h6 simple 14h4 simple 16h2 simple 10p8 simple 12p6 simple 14p4 simple 16p2 simple software compilers support the three different global olmc modes as different device types. these device types are listed in the table below. most compilers have the ability to automatically select the device type, generally based on the register usage and output enable (oe) usage. register usage on the device forces the soft- ware to choose the registered mode. all combinatorial outputs with oe controlled by the product term will force the software to choose the complex mode. the software will choose the simple mode only when all outputs are dedicated combinatorial without oe control. the different device types listed in the table can be used to override the automatic device selection by the software. for further details, refer to the compiler software manuals. when using compiler software to configure the device, the user must pay special attention to the following restrictions in each mode. in registered mode pin 1 and pin 11 are permanently configured as clock and output enable, respectively. these pins cannot be con- figured as dedicated inputs in the registered mode. in complex mode pin 1 and pin 11 become dedicated inputs and use the feedback paths of pin 19 and pin 12 respectively. because of this feedback path usage, pin 19 and pin 12 do not have the feedback option in this mode. in simple mode all feedback paths of the output pins are routed via the adjacent pins. in doing so, the two inner most pins ( pins 15 and 16) will not have the feedback option as these pins are always configured as dedicated combinatorial output. registered complex simple auto mode select abel p16v8r p16v8c p16v8as p16v8 cupl g16v8ms g16v8ma g16v8as g16v8 log/ic gal16v8_r gal16v8_c7 gal16v8_c8 gal16v8 orcad-pld "registered" 1 "complex" 1 "simple" 1 gal16v8a pldesigner p16v8r 2 p16v8c 2 p16v8c 2 p16v8a tango-pld g16v8r g16v8c g16v8as 3 g16v8 1) used with configuration keyword. 2) prior to version 2.0 support. 3) supported on version 1.20 or later. output logic macrocell (olmc) compiler support for olmc all devices discontinued
specifications gal16v8 5 in the registered mode, macrocells are configured as dedicated registered outputs or as i/o functions. architecture configurations available in this mode are similar to the common 16r8 and 16rp4 devices with various permutations of polarity, i/o and register placement. all registered macrocells share common clock and output enable control pins. any macrocell can be configured as registered or i/ o. up to eight registers or up to eight i/o's are possible in this mode. dedicated input or output functions can be implemented as sub- sets of the i/o function. registered outputs have eight product terms per output. i/o's have seven product terms per output. the jedec fuse numbers, including the user electronic signature (ues) fuses and the product term disable (ptd) fuses, are shown on the logic diagram on the following page. registered configuration for registered mode - syn=0. - ac0=1. - xor=0 defines active low output. - xor=1 defines active high output. - ac1=0 defines this output configuration. - pin 1 controls common clk for the registered outputs. - pin 11 controls common oe for the registered outputs. - pin 1 & pin 11 are permanently configured as clk & oe for registered output configuration. combinatorial configuration for registered mode - syn=0. - ac0=1. - xor=0 defines active low output. - xor=1 defines active high output. - ac1=1 defines this output configuration. - pin 1 & pin 11 are permanently configured as clk & oe for registered output configuration. note: the development software configures all of the architecture control bits and checks for proper pin usage automatically. dq q clk oe xor xor registered mode all devices discontinued

specifications gal16v8 16 *c l includes test fixture and probe capacitance. electronic signature an electronic signature is provided in every gal16v8 device. it contains 64 bits of reprogrammable memory that can contain user defined data. some uses include user id codes, revision numbers, or inventory control. the signature data is always available to the user independent of the state of the security cell. note: the electronic signature is included in checksum calcula- tions. changing the electronic signature will alter the checksum. security cell a security cell is provided in the gal16v8 devices to prevent un- authorized copying of the array patterns. once programmed, this cell prevents further read access to the functional bits in the device. this cell can only be erased by re-programming the device, so the original configuration can never be examined once this cell is pro- grammed. the electronic signature is always available to the user, regardless of the state of this control cell. latch-up protection gal16v8 devices are designed with an on-board charge pump to negatively bias the substrate. the negative bias minimizes the potential of latch-up caused by negative input undershoots. ad- ditionally, outputs are designed with n-channel pull-ups instead of the traditional p-channel pull-ups in order to eliminate latch-up due to output overshoots. device programming gal devices are programmed using a lattice semiconductor- approved logic programmer, available from a number of manu- facturers. complete programming of the device takes only a few seconds. erasing of the device is transparent to the user, and is done automatically as part of the programming cycle. 1.0 2.0 3.0 4.0 5.0 -60 0 -20 -40 0 input voltage (volts) input current (ua) test point z 0 = 50, c l = 35pf* from output (o/q) under test +1.45v r 1 gal16v8d-3 output load conditions (see figure at right) test condition r 1 c l a5 0 35pf b high z to active high at 1.9v 50 35pf high z to active low at 1.0v 50 35pf c active high to high z at 1.9v 50 35pf active low to high z at 1.0v 50 35pf switching test conditions (continued) output register preload when testing state machine designs, all possible states and state transitions must be verified in the design, not just those required in the normal machine operations. this is because, in system operation, certain events occur that may throw the logic into an illegal state (power-up, line voltage glitches, brown-outs, etc.). to test a design for proper treatment of these conditions, a way must be provided to break the feedback paths, and force any desired (i.e., illegal) state into the registers. then the machine can be sequenced and the outputs tested for correct next state conditions. gal16v8 devices include circuitry that allows each registered output to be synchronously set either high or low. thus, any present state condition can be forced for test sequencing. if necessary, approved gal programmers capable of executing text vectors perform output register preload automatically. input buffers gal16v8 devices are designed with ttl level compatible input buffers. these buffers have a characteristically high impedance, and present a much lighter load to the driving logic than bipolar ttl devices. the gal16v8 input and i/o pins have built-in active pull-ups. as a result, unused inputs and i/o's will float to a ttl "high" (logical "1"). lattice semiconductor recommends that all unused inputs and tri-stated i/o pins be connected to another active input, v cc , or ground. doing this will tend to improve noise immunity and re- duce i cc for the device. typical input pull-up characteristic all devices discontinued
