FM93C56A
FM93C46A/56A/66A provides 1k/2k/4k bits of serial electrically erasable programmable read-only memory (EEPROM) organized as 64/128/256 words of 16 bits each (when the ORG pin is connected to VCC), and 128/256/512 words of 8 bits each (when the ORG pin is connected to ground).
The FM93C46A/56A/66A is enabled through the Chip Select pin (CS) and accessed via a three-wire serial interface consisting of Data lnput (DI), Data Output (DO), and Serial Clock (Sk). Upon receiving a read instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO. The write cycle is completely self-timed and no separate erase cycle is required before write. The write cycle is only enabled when the part is in the Erase/rite Enable State When CS is brought “high” following the initiation of a write cycle, The DO pin outputs the Ready/ Busy status of the part.
The device is the best choice for use in many industrial and commercial applications where low-power and low-voltage operations are essential
