BL93C46

Shanghai Belling Corp., Ltd BL93C46 1K bits (128 X 8 or 64 X 16) Three-wire Serial EEPROM Features Three-wire Serial Interface VCC = 1.8V to 5.5V 2 MHz 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 BL93C46 Description The BL93C46 provides 1024 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 64 words of 16 bits each, when the ORG pin is connected to VCC and 128 words of 8 bits each when it is tied to ground. TheBL93C46 is available in space-saving 8-lead PDIP, 8-lead TSSOP and 8-lead JEDEC SOIC packages. The BL93C46 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.
