Description
The BL93C56/66 provides 2048/4096 bits of serial electrically erasable programmable read only memory
(EEPROM) organized as 128/256 words of 16 bits each, when the ORG pin is connected to VCC and 256/512
words of 8 bits each when it is tied to ground. The BL93C56/66 is available in space-saving 8-lead PDIP,
8-lead TSSOP and 8-lead JEDEC SOIC packages. The BL93C56/66 is enabled through the Chip Select pin
(CS), and accessed via a 3-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift
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 it is in the Erase/Write Enable state. When CS is
brought “high” following the initiation of a write cycle, the DO pin outputs the Ready/Busy status.
