25LC160C-H/SN

Overview

The Microchip Technology 25LC160C-H/SN is a 16 Kbit (2,048 x 8-bit) Serial Electrically Erasable PROM (EEPROM). It supports the SPI compatible serial bus architecture with a maximum clock frequency of 5 MHz. The device operates within a supply voltage range of 2.5V to 5.5V and features an extended temperature range from -40°C to +150°C. It utilizes an 8-lead SOIC package.

Feature Summary

• Supports byte-level and page-level write operations with self-timed erase and write cycles.
• Includes built-in write protection mechanisms such as power-on/off data protection circuitry and a dedicated write-protect pin.
• Features a hold input that allows communication suspension without resetting the serial sequence.

Applications

• Data storage in automotive electronic systems requiring high-temperature reliability.
• Configuration memory for microcontrollers interfacing via SPI ports.
• Industrial control applications needing non-volatile parameter retention under extreme conditions.

Procurement Notes

Verify the specific suffix 'H' confirms the extended temperature grade (-40°C to +150°C) and 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status and AEC-Q100 qualification requirements against the latest manufacturer datasheet revision DS20002131D before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring operation at ambient temperatures up to +150°C. Ensure the host controller supports SPI Mode 0 or Mode 3 protocols. Verify that the system voltage remains within the 2.5V to 5.5V range to maintain specified electrical characteristics and endurance ratings.

Part Context

This part belongs to the 25LCXXX family of mid-density serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other densities in the series but is specifically optimized for 16 Kbit capacity. The 'C' designation typically aligns with specific feature sets within the broader product line.

Replacement Considerations

Direct replacements include other 25LC160 variants with matching interface and voltage specs, provided the temperature grade meets application needs. Cross-reference package dimensions and pinouts carefully when substituting with generic SPI EEPROMs.
