24CW160T-I/Q4B

Memory IC Overview

The Microchip Technology 24CW160T-I/Q4B is a 16 Kbit (2 k x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes an I2C interface with a maximum clock frequency of 1 MHz and features software write protection. The device operates within a supply voltage range of 1.6 V to 5.5 V, drawing a maximum active read current of 1 mA. It is housed in an 8-lead UDFN package and supports surface mount installation. The component ensures data retention for up to 200 years and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports I2C serial communication with software-based write protection mechanisms.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics needing configuration parameter retention
• Automotive modules operating within industrial temperature ranges

Memory IC Procurement Notes

Verify the complete part number including suffixes such as -I/Q4B to ensure correct temperature grade and packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the specific datasheet revision to validate electrical characteristics against design requirements. Ensure compatibility with system voltage levels ranging from 1.6 V to 5.5 V.

Memory IC Selection Notes

Select this component when a 16 Kbit capacity is required with I2C connectivity. The 1.6 V minimum operating voltage makes it suitable for low-power applications compared to standard 1.7 V variants. The industrial temperature rating (-40°C to +85°C) distinguishes it from commercial grade options. Verify that the UDFN-8 package fits the available PCB footprint constraints.

Memory IC Part Context

This EEPROM belongs to the Microchip 24CW series, which is characterized by its lower minimum operating voltage of 1.6 V compared to other 24-series counterparts like the 24CS or 24FC families. The 'CW' designation indicates the inclusion of software write protection features. The '-I' suffix specifies the industrial temperature range, while '/Q4B' denotes the specific tape and reel packaging format.

Memory IC Replacement Considerations

Direct substitutes include the 24CW160T-E/Q4B66KVAO for extended temperature applications. Other 24-series EEPROMs may require voltage level adjustments due to differing minimum operating voltages.
