Microchip Technology AT21CS01-STUM10-T

AT21CS01-STUM10-T Description

The AT21CS01-STUM10-T is a  2-pin memory (SI/O and Ground) that harvests energy from the SI/O pin to power the integrated circuit.  
AT21CS01-STUM10-T Features
 Low‑Voltage Operation: – AT21CS01 is self-powered via the 1.7V to 3.6V pull‑up voltage on the SI/O line – AT21CS11 is self-powered via the 2.7V to 4.5V pull‑up voltage on the SI/O line
Internally Organized as 128 x 8 (1 K-bit)
Industrial Temperature Range: -40°C to 85°C
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: – 15.4 kbps maximum bit rate in Standard Speed mode (AT21CS01 only) – 125 kbps maximum bit rate in High-Speed mode (AT21CS01 and AT21CS11)
8‑Byte Page Write or Single Byte Writes Allowed
Discovery Response Feature for Quick Detection of Devices on the Bus
ROM Zone Support: – The device is segmented into four 256‑bit zones, each of which can be permanently made read‑only (ROM)
256‑Bit Security Register: – Lower eight bytes contain a factory-programmed, read-only, 64‑bit serial number that is unique to all  Microchip single‑wire devices – Next eight bytes are reserved for future use and will read FFh – Upper 16 bytes are user‑programmable and permanently lockable
Self‑Timed Write Cycle: 5 ms Maximum
Manufacturer Identification Register: – Device responds with unique value for Microchip as well as density and revision information
High Reliability: – Endurance: 1,000,000 write cycles – Data retention: 100 years – IEC 61000-4-2 Level 4 ESD Compliant (±8 kV Contact, ±15 kV Air Discharge)
Green (Lead-free/Halide-free/RoHS Compliant) Package Options
Die Sale Options: Wafer Form and Tape and Reel
