Atmel AT93C66B
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). The write cycle is completely self-timed, and no separate erase cycle is required before write.| Part No. | AT93C66B |

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. Upon receiving a read instruction at DI, the address is decoded and the data is clocked out serially on the data output pin, DO.
