Memory IC datasheet and documents for 25AA320A-I/MS

25AA320A-I/MS

Memory IC Overview

The Microchip Technology 25AA320A-I/MS is a 32-Kbit Serial Electrically Erasable PROM featuring a 4096 x 8-bit organization. It operates via an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC voltages between 4.5V and 5.5V, scaling to 5 MHz at 2.5V–4.5V and 3 MHz at 1.8V–2.5V. The device supports a supply voltage range of 1.8V to 5.5V and includes a 32-byte page size for write operations. It is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

Supports high-speed SPI communication with up to 10 MHz clock frequency
Includes hardware write protection via WP pin and software block protection bits
Features built-in power-on/off data protection and write enable latch mechanisms
Provides hold functionality to pause serial transmission without resetting the sequence

Memory IC Applications

Microcontroller system data storage
Configuration parameter retention
Calibration value storage

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific voltage range requirements align with the 1.8V to 5.5V specification. Ensure compatibility with the SPI interface protocol used in the target design. Check for any recent product change notifications regarding packaging or material composition.

Memory IC Selection Notes

Select this component when a low-pin-count EEPROM with SPI interface is required. It is suitable for designs needing industrial temperature operation and wide voltage support. Consider the 32-byte page write limitation when designing write algorithms. Verify that the 8-lead MSOP package fits the available PCB space.

Memory IC Part Context

This part belongs to the 25XX320A family of 32-Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 25LC320A but differs in minimum operating voltage. The family utilizes a standard SPI interface and offers various package options including PDIP, SOIC, TSSOP, and TDFN.
