Three-wire Serial Electrically Erasable Programmable Read-only Memory
Description

The Atmel AT93C56B/66B 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 the ORG pin is tied to ground). The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential. The AT93C56B/66B is available in space-saving 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead UDFN, 8-lead XDFN, and 8-ball VFBGA packages. The AT93C56B/66B is enabled through the chip select pin (CS) and accessed via a three-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 the part 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 of the part. The AT93C56B/66B operates from to 5.5V.

This is a stress rating only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

DATA REGISTER DI MODE DECODE LOGIC OUTPUT BUFFER

When the ORG pin is connected to VCC, the x 16 organization is selected. When it is connected to ground, the x 8 organization is selected. If the ORG pin is left unconnected and the application does not load the input beyond the capability of the internal 1M pull-up resistor, then the x 16 organization is selected.

Applicable over recommended operating range from = 1.0MHz, VCC = +5.0V (unless otherwise noted)
