24FC512T-I/OT

Memory IC Overview

The Microchip Technology 24FC512T-I/OT is a 512 Kbit (64K x 8) serial electrically erasable PROM featuring a two-wire I²C compatible interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz at voltages of 2.5V or higher, with a maximum access time of 400 ns. The device utilizes a 5-lead SOT-23 package and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation at VCC ≥ 2.5V
• Includes hardware write protection via the WP pin
• Features a 128-byte page write buffer for efficient data transfer
• Provides Schmitt trigger inputs for noise suppression

Memory IC Applications

• Personal communications devices

Memory IC Procurement Notes

Verify that the ordering suffix 'OT' corresponds to the 5-lead SOT-23 package configuration. Confirm the temperature grade 'I' matches the required -40°C to +85°C operating range. Ensure the specific revision of the datasheet DS20001754Q aligns with the manufacturing lot requirements.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.7V is required alongside high-speed 1 MHz performance. It is suitable for designs needing compact surface-mount packaging in space-constrained environments. Compare against 24LC512 variants if lower speed or different voltage constraints apply.
