MCHPAT25M02-SSHM-T
Overview
The AT25M02-SSHM-T is a high-density 2Mbit SPI serial EEPROM from Microchip, organized as 256K x 8 bits. It operates over a wide voltage range of 1.7V to 5.5V and supports high-speed clock frequencies up to 5 MHz. This non-volatile memory solution is designed for applications requiring frequent data writes and long-term retention in a compact 8-SOIC footprint.
Why Choose This Part
This device offers exceptional reliability with an endurance rating of 1,000,000 write cycles and ESD protection exceeding 4,000V. Its low-power performance is notable, consuming only 0.3mA for reads at 1.8V and maintaining a standby current of 80uA. The inclusion of a hardware Write-Protect pin and block protection software provides robust data security against accidental writes.
Applications
Key Specifications
Getting Started
Interface the AT25M02 with any microcontroller using a standard 4-wire SPI bus (Modes 0 or 3). Engineers can utilize Microchip's MPLAB Starter Kits or generic SPI libraries for AVR and SAM microcontrollers to implement the 24-bit addressing required for this 2Mbit capacity. Ensure the WP and HOLD pins are tied high if not used to prevent bus communication issues.
Also Consider
STMicroelectronics
- Offers similar 2Mbit density and SPI interface but supports a higher clock frequency up to 10 MHz.
