TSSOP 8 |
1Kbit, 3-wire Bus Serial Automotive EEPROM, supports x8 or x16 data format memory organization.
The AT93C46 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. The device is optimized for use in many automotive applications where low power and low voltage operations are essential. The AT93C46 is available in space-saving 8-lead TSSOP and 8-lead JEDEC SOIC packages. The AT93C46 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.
