24LC32AT-I/MS

Memory IC Overview

The Microchip Technology 24LC32AT-I/MS is a 32-Kbit Electrically Erasable PROM (EEPROM) organized as a single block of 4K x 8-bit memory. It operates with a supply voltage range of 2.5V to 5.5V and supports I2C compatible two-wire serial interfaces at clock frequencies up to 400 kHz. The device features a 900 ns access time, a maximum page write time of 5 ms, and an 8-lead MSOP surface-mount package. It is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports hardware write protection via the WP pin to inhibit array writes when tied to VCC.
• Includes a 32-byte page write buffer to allow efficient data transfer without repeated start conditions.
• Provides Schmitt trigger inputs on SDA and SCL pins for improved noise suppression.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices
• Low-power embedded applications

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status if environmental regulations apply to the end product. Ensure the design accounts for the 2.5V minimum operating voltage specified for the LC series.

Memory IC Selection Notes

Select this component for designs requiring 32-Kbit capacity with I2C connectivity. Compare against the 24AA32A variant if operation below 2.5V is necessary, as the LC series requires a minimum of 2.5V. Consider the MSOP package dimensions for PCB layout constraints.

Memory IC Part Context

This part belongs to the 24XX32A family of 32-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA32A which support lower voltage operation down to 1.7V. The device utilizes a standard 8-pin configuration common across multiple package styles including SOIC, TSSOP, and DFN.

Memory IC Replacement Considerations

Direct substitutes within the same package include other 24LC32A variants such as 24LC32AT-I/ST or 24LC32A-I/SM, provided the interface and electrical characteristics remain compatible.
