25LC160C-I/SN

Overview

The Microchip Technology 25LC160C-I/SN is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It operates via an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. The device supports a supply voltage range of 2.5V to 5.5V and utilizes an 8-lead SOIC package. It includes a 16-byte page buffer, self-timed erase/write cycles of 5 ms max, and industrial temperature ratings from -40°C to +85°C.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via WP pin and software block protection
• Features power-on/off data protection circuitry and write enable latch
• Provides hold functionality to pause serial transmission without resetting sequence

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage in embedded systems

Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) and 'SN' denotes the 8-lead SOIC package. Confirm RoHS compliance status as per current manufacturing notices. Ensure the ordering part number matches the exact voltage and page size requirements for your design.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. The 'C' variant specifies a 16-byte page size, distinct from the 32-byte 'D' version. Choose the 'I' grade for industrial environments requiring operation down to -40°C. Verify that the host microcontroller supports the necessary SPI modes and voltage levels.

Part Context

This device belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 25AA160C series but differs in minimum operating voltage specifications. The family offers various packaging options including PDIP, TSSOP, MSOP, and TDFN.

Replacement Considerations

Direct substitutes within the same family include 25LC160C-E/SN (Automotive grade) or 25LC160D-I/SN (32-byte page size). Cross-voltage equivalents like 25AA160C-I/SN are available but require verification of the 1.8V minimum supply capability.
