Microchip Technology's AT21CS01-MSHM12-B is a 1 Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 128 words by 8 bits. This CMOS component operates across a supply voltage range of 1.7V to 3.6V and features a 1-Wire serial bus interface, enabling efficient data transfer with minimal pin count. Designed for surface mounting, it utilizes a VSON package (JESD-30 code R-PSSO-N2) with a 2.00mm terminal pitch and a low profile of 0.40mm maximum seated height. The AT21 series EEPROM offers robust data retention for at least 100 years and endurance of 100,000 write cycles. Applications include industrial control, consumer electronics, and automotive systems where reliable non-volatile data storage is critical. The device supports software write protection and has a maximum write cycle time of 5ms. Its operating temperature range is -40°C to +85°C.
