25LC160CT-I/ST

Overview

The Microchip Technology 25LC160CT-I/ST 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 ≥ 4.5V. The device operates within a voltage range of 2.5V to 5.5V and supports industrial temperatures from -40°C to +85°C. It employs a 16-byte page size, TSSOP-8 packaging, and offers >1M erase/write cycle endurance with data retention exceeding 200 years.

Feature Summary

• Supports sequential read operations and self-timed erase/write cycles with a maximum duration of 5 ms.
• Includes built-in write protection mechanisms such as power-on/off data protection, a write enable latch, and a dedicated write-protect pin.
• Features a hold input that allows the host to pause serial communication without resetting the sequence.

Applications

• Data storage for microcontroller systems via SPI interface
• Configuration memory in embedded applications
• Parameter storage requiring high reliability and long data retention

Procurement Notes

Verify the specific suffix 'CT' against official documentation to confirm tape-and-reel packaging and cut-tape availability options. Ensure the 'I' temperature grade matches the required operational environment. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement specifications.

Selection Notes

Select this component when an SPI interface is preferred over I2C or Microwire protocols. Choose the 'C' version variant specifically for its 16-byte page size requirement. Verify that the operating voltage range of 2.5V to 5.5V aligns with the system power supply constraints.

Part Context

This part belongs to the 25LC160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'C' designation indicates a 16-byte page size, distinguishing it from the 'D' variant which features a 32-byte page size. The 'L' prefix denotes a 2.5V minimum operating voltage.

Replacement Considerations

Public confirmed substitute part numbers include 25LC160BT-E/ST and 25LC160B-I/ST.
