25LC080C-H/SN

Overview

The Microchip Technology 25LC080C-H/SN is an 8K-bit (1,024 x 8) Serial Electrically Erasable PROM (EEPROM) housed in an 8-lead SOIC package. It supports the SPI compatible serial bus architecture with a maximum clock frequency of 5 MHz and operates within a supply voltage range of 2.5V to 5.5V. The device features byte and page-level write operations, self-timed erase/write cycles, and block write protection capabilities. It is designed for extended temperature operation ranging from -40°C to +150°C.

Feature Summary

• Supports Serial Peripheral Interface (SPI) compatible communication with separate data input and output lines.
• Includes built-in hardware write protection via the WP pin and software control through the STATUS register.
• Features power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.
• Provides sequential read capability with automatic address pointer incrementation.

Applications

• Microcontroller systems requiring non-volatile data storage
• Industrial applications operating at elevated temperatures
• Automotive electronics requiring high reliability

Procurement Notes

Verify that the specific suffix 'H' corresponds to the extended temperature grade (-40°C to +150°C) as defined in the official datasheet. Confirm the 'SN' package designation matches the required 8-lead SOIC physical dimensions. Ensure compatibility with the 5 MHz maximum clock speed requirement for your system design.

Selection Notes

Select this component when an 8K-bit EEPROM with SPI interface is required for high-temperature environments. The device offers robust data retention exceeding 200 years and endurance over 1,000,000 erase/write cycles. Consider the page size of 16 bytes for efficient data writing operations within the same physical page boundary.

Part Context

This part belongs to the 25LCXXX family of mid-density serial EEPROMs manufactured by Microchip Technology. The family includes variants with different densities and temperature grades, all sharing a common SPI interface protocol. The 25LC080C specifically denotes the 8K-bit density variant within this series.
