AT25010B-SSHL-T

Memory IC Overview

The AT25010B-SSHL-T is a 1 Kbit (128 x 8) Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) manufactured by Microchip Technology. It features an SPI-compatible interface supporting Modes 0 and 3, with a maximum clock frequency of 20 MHz at 5V operation. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to +85°C. It utilizes an 8-SOIC package and includes hardware and software write protection mechanisms.

Memory IC Feature Summary

• Supports SPI Modes 0 and 3 for synchronous serial communication
• Includes dedicated Write-Protect (WP) pin for hardware data protection
• Features block write protection allowing quarter, half, or full array locking
• Provides Hold function to pause serial sequences without resetting

Memory IC Applications

• Industrial control systems requiring low-power non-volatile storage
• Commercial applications needing robust data retention
• Microcontroller-based designs utilizing SPI bus interfaces

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' corresponds to tape-and-reel packaging rather than tube packaging when sourcing components. Confirm that the device variant matches the required voltage grade and temperature range specifications for your application environment before finalizing procurement orders.

Memory IC Selection Notes

Select this component for designs requiring small memory capacity with high-speed SPI access. Ensure the host controller supports the required SPI modes and voltage levels. Consider the SOIC package dimensions for PCB layout constraints and verify power supply stability during write cycles to prevent data corruption.

Memory IC Part Context

This part belongs to the AT25010B/AT25020B/AT25040B family of SPI Serial EEPROMs. These devices are optimized for low-power and low-voltage operations in various industrial and commercial environments. The family shares common instruction sets and electrical characteristics, differing primarily in memory density and physical package options.

Memory IC Replacement Considerations

Compatible substitutes include AT25010B-SSHL-B and AT25010B-XHL-T, which share identical functional specifications but differ in packaging format.
