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.
