LOGIC INPUTS AND OUTPUTS
The serial interface consists of the DATA, CLOCK, and LATCH leads. The data is clocked in on the positive edge of the
clock (see Figure 2). The 9-bit (D0D8) serial data word is loaded during the positive edge of the latch signal. The latch
signal should occur before the next positive edge of the clock.
The shutdown bit of the data word places all VCC and Vpp outputs in a high-impedance state and reduces chip quiescent
current to 1
A to conserve battery power.
The serial interface is designed to be compatible with serial-interface PCMCIA controllers and current PCMCIA and Japan
Electronic Industry Development Association (JEIDA) standards.
An overcurrent output (OC) is provided to indicate an overcurrent or overtemperature condition in any of the VCC and VPP
outputs as previously discussed.
