25LC160C-E/SN

Overview

The Microchip Technology 25LC160C-E/SN is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It is housed in an 8-lead SOIC package.

Feature Summary

• Supports block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Includes built-in power-on/off data protection circuitry and a write enable latch mechanism.
• Features a hold pin that suspends transmission during serial sequences without resetting the sequence.

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Procurement Notes

Verify the specific suffix 'E' indicates automotive temperature grade (-40°C to +125°C) if required, as datasheet tables list 'I' for industrial and 'E' for automotive. Confirm the 'SN' suffix corresponds to the 8-lead SOIC package. Ensure the 'C' designation matches the 16-byte page size requirement rather than the 32-byte 'D' version.

Selection Notes

Select this component when an SPI interface is required for non-volatile memory with low power consumption. The 16Kbit capacity suits applications needing moderate data retention. Verify voltage compatibility across the 2.5V to 5.5V range. Consider the 16-byte page size limitation for write operations compared to larger page variants.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The family shares core architecture but varies by page size ('C' vs 'D') and operating temperature grade ('I' vs 'E'). The 25LC160C variant specifically targets standard logic voltage levels.
