Memory IC datasheet and documents for 25AA320T-I/SN

25AA320T-I/SN

Memory IC Overview

The Microchip Technology 25AA320T-I/SN is a 32 Kbit serial Electrically Erasable PROM featuring a 4096 x 8 bit organization. It utilizes an SPI-compatible interface with a maximum clock frequency of 1 MHz and operates within a supply voltage range of 1.8V to 5.5V. The device supports industrial temperature ranges from -40°C to +85°C and is housed in an 8-pin SOIC package.

Memory IC Feature Summary

Supports block write protection for none, one-quarter, one-half, or all memory arrays
Includes built-in power on/off data protection circuitry and a write enable latch
Features a hold pin to suspend transmission without resetting the serial sequence

Memory IC Applications

Microcontroller system data storage
Configuration parameter retention
Calibration value storage

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'SN' indicates the 8-pin SOIC package. Confirm the 'T' suffix matches the required tape and reel packaging format for automated assembly processes.

Memory IC Selection Notes

Select this component when a low-power EEPROM with a wide voltage operating range is required. Ensure the design accommodates the 1 MHz maximum clock speed and verify that the 8-pin SOIC footprint aligns with the PCB layout constraints.

Memory IC Part Context

This part belongs to the 25XX320 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25LC320 and 25C320 variants, differing primarily in supply voltage requirements and maximum clock frequencies.
