mb94r215b 6 n n n n handling devices 1. preventing latchup latch-up may occur in a cmos ic if a voltage greater than v cc or less than v ss is applied to an input or output pin, or if an above-rating voltage is applied between v cc and v ss . a latchup, if it occurs, significantly increases the power supply current and may cause thermal destruction of an element. when you use a cmos ic, be very careful not to exceed the absolute maximum rating. 2. treatment of n.c. pins be sure to use nc pins in open state. 3. rising time for power supply voltage ensure that the power supply rise time is 100 m s or less when using contact mode operation but, which may cause misoperation resulting in the corruption of fram data. 4. power supply off time ensure that the power supply off time is 1ms or longer when using contact mode operation. 5. magnetic field strength rise time see the n rf interface in contactless operation section for points to note regarding contactless operation. 6. when using both contact and contactless operation when operating in contact mode, ensure there is no rf input from the antenna. when operating in contactless mode, ensure that the contact terminals are open circuit.

mb94r215b 12 n n n n rf interface in contactless operation 1. flow at carrier on communications between picc (card) and pcd (r/w) is based on a "pcd talk first" protocol in accordance with the procedure described below. (1) rf power is supplied to picc by the magnetic field generated by pcd. (2) picc is able to receive within 5 ms of rf power on. (3) picc waits with no response until receiving a command from pcd (receive standby state). (4) pcd sends a command to picc (sent approx. 10 ms after rf power on). (5) picc executes the operation specified by the pcd instruction and sends a response to pcd on completion. 2. power supply ( 1 ) carrier frequency fc : 13.56 mhz 7 khz ( 2 ) picc operating magnetic field strength (when not modulated) : 4.0 a/m to 7.5 a/m 2 ms (max) 5 ms (max) carrier on 100 m s to 500 m s picc : ask reception enabled time standard at carrier on

mb94r215b 14 4. notes on carrier when handling the device for the contactless ic cards, observe the following to prevent the improper operation or damage to the device. keep in mind, however, that the transmission characteristics are dependent on the antenna design and reader/writer characteristics, so the values below are only for reference and the values below are not intended to guarantee the finished card characteristics. ensure that operation and transmission characteristics have no problems in the environments where you use a card. (1) rising of carrier ensure that the carrier rise time is in the range 100 m s to 500 m s and that the carrier rises continuously with a deviation of 2.4 % or less. (2) falling of carrier ensure that the carrier fall time is in the range 100 m s to 100 ms and that the carrier falls continuously with a deviation of 2.4 % or less. ab rising time = 100 m s to 500 m s deviation = (a - b) / (a + b) rising waveform of carrier ba deviation = (a - b) / (a + b) falling time = 100 m s to 100 ms falling waveform of carrier
mb94r215b 15 (3) stop of carrier the mb94r215b has internal capacitance to smooth the power supply and similar. accordingly, always provide a gap of 100 ms or longer between halting and restarting the carrier to allow the internal state to stabilize. (4) carrier deviation (noise, momentary stop, etc.) ensure that the deviation when not modulated is 2.4 % or less. the following problems may occur if variation (noise) in excess of this limit occurs. if the carrier falls within the ask modulation level range (8 to 14 % ), this may be misinterpreted as a modula- tion signal. however, if the frame is determined to be invalid, the command receive block will be cleared and the device will return to the command standby state. if the carrier variation exceeds the ask modulation level range in the region 0 a/m to 12 a/m, misoperation may occur and internal circuits may reset. in this case, temporarily turn off the carrier in accordance with the precautions in "(3) stop of carrier". if the carrier is not turned off, misoperation may corrupt internal data. if the carrier exceeds the ask modulation level range over 12a/m, the device may be damaged due to the increase in internal voltage. carrier stop time 3 100 ms stop time of carrier c d 4 a/m 12 a/m e deviation = (c - d) / (c + d) 100 = (e - c) / (e + c) 100 carrier deviation
mb94r215b 16 (5) operating conditions contactless devices (cards) can only be used in a one-to-one communication with a reader/writer. do not try to use the mb94r215b embedded card to a reader/writer with multiple other contactless cards. use of multiple contactless devices may corrupt data or cause the device to misoperate. using the device in the presence of strong magnetic fields (12 a/m or stronger) or with reader/writers that do not match the specifications may cause data corruption.
