BL93C56

Shanghai Belling Corp., Ltd BL93C56/BL93C66 BL93C56/BL93C66 2K bits (256 X 8 or 128 X 16)/ 4K bits (512 X 8 or 256 X 16) Three-wire Serial EEPROM Features Three-wire Serial Interface VCC = 1.8V to 5.5V Sequential Read Operation 2 MHz Clock Rate (5V) Compatibility Self-timed Write Cycle (5 ms max) 1 Million Write Cycles guaranteed Data Retention > 100 Years 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP Packages 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.
