24CW320T-I/ST

Memory IC Overview

The Microchip Technology 24CW320T-I/ST is a 32 Kbit (4 k x 8) I2C serial EEPROM housed in an 8-TSSOP package. It operates within a supply voltage range of 1.6 V to 5.5 V and supports clock frequencies up to 1 MHz with a 450 ns access time. The device features software write protection, 200-year data retention, and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports standard I2C interface with clock frequencies up to 1 MHz
• Includes software-based write protection mechanisms
• Operates across a wide supply voltage range from 1.6 V to 5.5 V

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded memory for configuration parameters in IoT devices

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' against official Microchip documentation to confirm the industrial temperature grade (-40°C to +85°C) and TSSOP-8 packaging. Ensure compatibility with system voltage levels between 1.6 V and 5.5 V. Confirm that the required I2C address bits align with the device's hardware pin configuration before procurement.

Memory IC Selection Notes

Select this component when a 32 Kbit capacity is required alongside high-speed 1 MHz I2C communication. It is suitable for designs needing operation at voltages as low as 1.6 V. Compare against the 24LC32AT series if lower power consumption is critical, noting the 24CW320T-I/ST offers higher speed but potentially higher current draw.

Memory IC Part Context

This part belongs to the 24CW320 family of serial EEPROMs designed for general-purpose data storage. It shares architectural similarities with other 24CW series devices like the 24CW1280, differing primarily in memory density. The 'I' designation indicates industrial temperature rating, while 'ST' specifies the surface-mount TSSOP package type.

Memory IC Replacement Considerations

The 24CW320T-I/MUY serves as a direct functional substitute offering identical electrical specifications but utilizes a UDFN-8 package instead of TSSOP-8. Designers must verify footprint compatibility and reflow soldering profiles when substituting packages.
