AT21CS01 - EEPROM

Description

The Atmel® AT21CS01 provides 1,024 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 128 words of 8 bits each.

The device’s software addressing scheme allows up to eight devices to share a common Single-Wire bus.

Features

  • Low voltage operation ̶ Device is self-powered via 1.7V to 3.6V pull-up voltage on the SI/O line.
  • Internally organized as 128 words of 8 bits each (1-Kbit).
  • Single-Wire serial interface with I2C protocol structure ̶ Device communication is achieved through a single I/O pin.
  • Standard Speed and High Speed Mode options ̶ 15.4kbps maximum bit rate in Standard Speed Mode ̶ 125kbps maximum bit rate in High Speed Mode.
  • 8-byte Page Write or single Byte Writes allowed.
  • Disc.
