CY62128V Family
128K x 8 Static RAM
Features
* Low voltage range: -- 2.7V-3.6V (CY62128V) -- 2.3V-2.7V (CY62128V25) * * * * * -- 1.6V-2.0V (CY62128V18) Low active power and standby power Easy memory expansion with CE and OE features TTL-compatible inputs and outputs Automatic power-down when deselected CMOS for optimum speed/power three-state drivers. These devices have an automatic power-down feature, reducing the power consumption by over 99% when deselected. The CY62128V family is available in the standard 450-mil-wide SOIC, TSOP, and STSOP packages. Writing to the device is accomplished by taking chip enable one (CE1) and write enable (WE) inputs LOW and the chip enable two (CE2) input HIGH. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A16). Reading from the device is accomplished by taking chip enable one (CE1) and output enable (OE) LOW while forcing write enable (WE) and chip enable two (CE 2) HIGH. Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins. The eight input/output pins (I/O0 through I/O7) are placed in a high-impedance state when the device is deselected (CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or during a write operation (CE1 LOW, CE2 HIGH, and WE LOW).
Functional Description
The CY62128V family is composed of three high-performance CMOS static RAMs organized as 131,072 words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and

Notes: 5. Test conditions assume signal transition time of 5 ns or less timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified IOL/IOH and 100-pF load capacitance. 6. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 7. tHZOE, tHZCE, and tHZWE are specified with CL = 5 pF as in part (b) of AC Test Loads. Transition is measured 200 mV from steady-state voltage. 8. The internal write time of the memory is defined by the overlap of CE1 LOW, CE2 HIGH and WE LOW. CE1 and WE signals must be LOW and CE2 HIGH to initiate a write and either signal can terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write. 9. The minimum write cycle time for write cycle #3 (WE controlled, OE LOW) is the sum of tHZWE and tSD. 10. Device is continuously selected. OE, CE = VIL, CE2=VIH. 11. WE is HIGH for read cycle.
