25LC160CT-E/MS

Overview

The Microchip Technology 25LC160CT-E/MS is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with SCK, SI, and SO signals controlled by CS. The device supports a maximum clock frequency of 10 MHz at VCC ≥ 4.5V, reducing to 5 MHz at 2.5V ≤ VCC < 4.5V. Operating voltage ranges from 2.5V to 5.5V. It includes a 16-byte page buffer, self-timed write cycles up to 5 ms, and block write protection. Endurance exceeds 1 million erase/write cycles with data retention over 200 years.

Feature Summary

• Supports high-speed SPI communication with hold functionality for interrupt servicing
• Includes built-in power-on/off data protection and write enable latch mechanisms
• Offers programmable block write protection for array segments
• Features robust reliability with high ESD protection and long data retention

Applications

• Microcontroller system data storage
• Configuration parameter storage
• Calibration data retention
• Device identification information storage

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging and 'E' denotes automotive temperature range (-40°C to +125°C). Confirm the 'C' variant specifies a 16-byte page size distinct from the 'D' variant. Ensure compatibility with required voltage levels and interface timing constraints before integration.

Selection Notes

Select this component for applications requiring non-volatile memory with SPI interface and automotive grade temperature stability. Consider the 16-byte page size limitation for write operations. Evaluate power consumption requirements against the specified read and standby currents. Verify package availability in MSOP-8 format for PCB layout constraints.

Part Context

This part belongs to the 25LC160C/D family of 16 Kbit Serial EEPROMs. It shares architectural similarities with the 25AA160C/D series but differs in minimum operating voltage. The 'E' suffix identifies it as an automotive qualified device, while standard industrial versions use the 'I' suffix. It competes in the low-density serial memory segment.

Replacement Considerations

Public confirmed substitute: 25LC160DT-E/MS (32-byte page size).
