24FC512T-I/SM

Memory IC Overview

The Microchip Technology 24FC512T-I/SM is a 512 Kbit (64K x 8) Serial Electrically Erasable PROM featuring an I²C compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz at VCC ≥ 2.5V. The device supports page writes up to 128 bytes and includes hardware write protection via the WP pin. It is housed in an 8-lead TSSOP package, rated for industrial temperatures (-40°C to +85°C), and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Supports high-speed serial communication with clock frequencies up to 1 MHz under standard operating voltages.
• Features a 128-byte page write buffer to optimize data throughput during memory programming cycles.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides hardware-based write protection through the dedicated WP pin to secure array integrity.

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing low-power memory solutions
• Industrial control applications utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'SM' corresponds to the 8-Lead TSSOP package configuration as defined in the official datasheet. Confirm that the 'I' designation matches the required industrial temperature range specifications for your application environment. Ensure compatibility with the host controller's I²C voltage levels and pull-up resistor requirements before integration.

Memory IC Selection Notes

Select this component when a 512 Kbit capacity is required alongside high-speed 1 MHz I²C performance. It is suitable for designs operating between 1.7V and 5.5V where low standby current is critical. Choose this part over variants with lower clock speeds if system timing constraints demand faster data transfer rates within the same memory footprint.

Memory IC Part Context

This device belongs to the 24XX512 family of Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA512 and 24LC512 but distinguishes itself with support for higher clock frequencies up to 1 MHz. The family utilizes a standardized I²C protocol, allowing for flexible addressing and cascading capabilities across multiple devices on a single bus.
