25LC160C-E/P

Overview

The Microchip Technology 25LC160C-E/P 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, SO, and CS signals for communication. The device supports a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. Operating voltage ranges from 2.5V to 5.5V. It includes a 16-byte page size and self-timed erase/write cycles with a maximum duration of 5 ms. The component operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-lead PDIP package.

Feature Summary

• Supports hardware write protection via the WP pin and STATUS register bits to prevent inadvertent array modifications.
• Includes built-in power-on/off data protection circuitry and a write enable latch mechanism.
• Features a HOLD input that allows suspension of serial communication without resetting the sequence.

Applications

• Data storage for microcontroller systems requiring non-volatile memory
• Configuration parameter retention in embedded devices
• Calibration data storage for sensor interfaces

Procurement Notes

Verify the specific suffix 'E' indicates the automotive temperature grade (-40°C to +125°C) if required by your design, as datasheet tables list 'I' (Industrial) and 'E' (Automotive) grades separately. Confirm the 'P' suffix corresponds to the 8-lead PDIP package type. Ensure the 'C' designation matches the 16-byte page size requirement rather than the 32-byte 'D' version. Cross-reference the full part number against the manufacturer's current selection guide to confirm availability status.

Selection Notes

Select this component when an SPI interface is preferred over I2C for simpler protocol implementation. Choose the 25LC160C variant specifically for applications requiring a 16-byte page buffer size. Consider the Automotive grade ('E') only if the system environment exceeds the Industrial temperature limit of +85°C. Verify that the 2.5V minimum operating voltage aligns with the target system's supply rails.

Part Context

This device belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but differs in page sizes and voltage tolerances. The 'LC' designation specifies the 2.5V to 5.5V operating range, distinguishing it from the 'AA' series which supports lower voltages down to 1.8V.
