24LC32A-I/MS

Memory IC Overview

The Microchip Technology 24LC32A-I/MS is a 32-Kbit Electrically Erasable PROM (EEPROM) organized as a single block of 4K x 8-bit memory. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz for VCC between 2.5V and 5.5V. The device operates on a single supply voltage ranging from 2.5V to 5.5V, with typical active current of 1 mA and standby current of 1 µA. It supports page write operations up to 32 bytes with a maximum write cycle time of 5 ms. The component is housed in an 8-lead MSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication via SDA and SCL pins
• Includes hardware write protection controlled by the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Advanced low-power applications

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature range (-40°C to +85°C). Confirm the voltage operating range matches the 2.5V to 5.5V specification required for the 24LC32A variant, distinct from the 1.7V capable 24AA32A series. Ensure RoHS compliance requirements are met for the target assembly process.

Memory IC Selection Notes

Select this component when a 32-Kbit non-volatile memory solution with I2C interface is required within the industrial temperature range. The 24LC32A variant is specifically designed for applications requiring a minimum supply voltage of 2.5V, distinguishing it from lower voltage options. Consider the 32-byte page write buffer capability for efficient data writing operations in embedded systems.

Memory IC Part Context

This part belongs to the 24XX32A family of 32-Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA32A which support lower voltages down to 1.7V. The 24LC32A series is optimized for standard 2.5V to 5.5V logic levels, offering compatibility with a wide range of microcontrollers and system buses while maintaining low power consumption characteristics.

Memory IC Replacement Considerations

The 24AA32AT-I/MS is a functional substitute within the same package and temperature range, though it supports a lower voltage range starting at 1.7V instead of 2.5V.
