The Microchip Technology AT21CS01-U11M0B-B is a 1 Kbit serial EEPROM organized as 128 words by 8 bits. This CMOS device utilizes a 1-Wire serial bus interface for communication, enabling efficient data transfer with minimal pin count. It features a robust endurance of 1,000,000 write cycles and a data retention of over 100 years. Operating from a supply voltage range of 1.7V to 3.6V, the AT21CS01 is suitable for applications requiring low power consumption, with a standby current of just 1.5µA. The memory organization includes 8-byte pages for efficient writing. The component is housed in a compact R-PBGA-B4 package (4x4mm, 0.400mm pitch) with a low profile (0.355mm seated height), making it ideal for space-constrained designs. This EEPROM finds application in automotive, industrial, and consumer electronics sectors where reliable data storage is critical.
