Description

The a 2-pin memory (SI/O signal and Ground) that harvests energy from the signal pin to power the integrated circuit. It provides 1,024 bits of Serial Electrically Erasable and Programmable ReadOnly Memory (SEEPROM) organized as 128 words of eight bits each. The device is optimized to add configuration and use information in unpowered attachments using a two-point mechanical connection that brings only one signal (SI/O) and GND to the unpowered attachment. Some unpowered attachment application examples include analog sensor calibration data storage, ink and toner printer cartridge identification, and management of aftermarket consumables. The device's software addressing scheme allows up to eight devices to share a common singlewire bus. The device is available in spacesaving package options and operates with an external pullup voltage from 3.6V on the SI/O line (AT21CS01) or from 4.5V on the SI/O line (AT21CS11).
