AT93C46EN-SH-B

ATMEL  AT93C46EN-SH-B  EEPROM, 1 Kbit, 64 x 16位, 2 MHz, 串行, SOIC, 8 引脚

The is a MICROWIRE-compatible 1kB 3-wire serial Electrically Erasable Programmable Read-Only Memory EEPROM organized as 64 words of 16-bit each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT93C46E 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 DO pin. 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.
