AT25160NSI-2.7 – SPI Serial EEPROM – Microchip (Atmel)

The AT25160NSI-2.7 is a 16Kbit (2,048 x 8) SPI Serial EEPROM from Atmel (now Microchip) in an 8-lead JEDEC SOIC package, rated for low-voltage operation from 2.7V to 5.5V. This obsolete, hard-to-find device is available for RFQ from Pacific Component Xchange.

The AT25160NSI-2.7 is a 16-Kbit (16,384-bit) SPI Serial EEPROM originally manufactured by Atmel Corporation, now part of Microchip Technology. The memory array is organized as 2,048 words of 8 bits each (2K x 8) and communicates over a Serial Peripheral Interface (SPI) bus, supporting SPI modes 0 (0,0) and 3 (1,1). It is the SOIC package member of the AT25080/160/320/640 family; the corresponding full factory ordering code is AT25160N-10SI-2.7, where the “SI” designator identifies the 8-lead JEDEC SOIC (8S1) package and the “-2.7” suffix marks the low-voltage option rated for operation from 2.7V to 5.5V. These SOIC parts are specified over the industrial temperature range of -40°C to +85°C.

This device is part of Atmel’s classic AT25160 SPI Serial EEPROM family, widely designed into industrial controllers, instrumentation, and embedded systems for storing configuration data, calibration constants, and non-volatile parameters. As a legacy Atmel/Microchip product, the AT25160NSI-2.7 is now obsolete and is increasingly difficult to source through authorized channels.
