24FC04T-E/ST36KVAO

Memory IC Overview

The Microchip Technology 24FC04T-E/ST36KVAO is a 4-Kbit Electrically Erasable PROM organized as two blocks of 256 x 8-bit memory. It features a 2-wire serial I2C interface with a maximum clock frequency of 1 MHz for VCC ranges from 1.7V to 5.5V. The device operates within an extended temperature range of -40°C to +125°C and holds AEC-Q100 qualification. It utilizes Low-Power CMOS technology, drawing a maximum active read current of 1 mA and a standby current up to 5 μA at extended temperatures. Data retention exceeds 200 years, and the component supports hardware write protection via the WP pin.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission protocol compatible with I2C standards
• Includes Schmitt trigger inputs and filter circuits for noise suppression on SCL and SDA lines
• Features a 16-byte page write buffer for efficient data storage operations
• Provides hardware write protection capability when the WP pin is tied to VCC

Memory IC Applications

• Automotive embedded systems requiring AEC-Q100 qualified components
• Industrial control applications operating in extended temperature environments
• Low-voltage portable devices utilizing single supply operation down to 1.7V
• Data logging systems requiring long-term non-volatile memory retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the presence of the 'E' designation indicates the extended temperature range suitable for automotive or industrial use. Ensure the 'T' suffix aligns with the desired reel packaging format for surface mount assembly processes.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C communication is required alongside low power consumption. The extended temperature rating makes it suitable for harsh environments where standard industrial parts may fail. Consider the hardware write-protect feature if system security against accidental overwrites is a priority.
