25LC128T-E/ST

Overview

The Microchip Technology 25LC128T-E/ST is a 128 Kbit Serial Electrically Erasable PROM featuring SPI-compatible communication. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 10 MHz. The device utilizes an 8-lead TSSOP package and functions across an extended temperature range of -40°C to +125°C. Key electrical characteristics include a maximum write current of 5 mA at 5.5V, standby current of 5 µA, and data retention exceeding 200 years with 1,000,000 erase/write cycle endurance.

Feature Summary

Supports high-speed serial communication via SPI interface with hold functionality for bus pausing
Includes hardware write protection mechanisms and block-level array protection
Features built-in power-on/off data protection circuitry and write enable latch
Provides high reliability with extended endurance and long-term data retention

Applications

Microcontroller system data storage
Industrial control applications requiring extended temperature operation
Automotive electronics systems
Embedded devices needing non-volatile parameter storage

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status and ensure the component meets AEC-Q100 qualification if automotive standards are mandated. Cross-reference datasheet revision numbers to guarantee functional compatibility with existing designs.

Selection Notes

Select this variant when extended industrial temperature ranges and surface-mount TSSOP packaging are required. Ensure supply voltage constraints align with the 2.5V minimum threshold. Consider page write limitations and block protection settings during system architecture planning.

Part Context

This component belongs to the 25LC128 family of 128 Kbit SPI EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 25AA128 but differs in operating voltage and temperature specifications. The 'T' suffix indicates tape and reel packaging, while 'E' denotes the extended temperature range capability.
