24FC16H-E/SN

Memory IC Overview

The Microchip Technology 24FC16H-E/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols, supporting clock frequencies up to 1 MHz across a supply voltage range of 1.7V to 5.5V. The device operates within an extended temperature range of -40°C to +125°C and utilizes low-power CMOS technology with standby currents as low as 3 μA. It includes hardware write-protect capabilities for half the array and supports page writes of up to 16 bytes.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Low-power CMOS design enabling operation down to 1.7V with minimal active and standby current consumption
• Integrated Schmitt trigger inputs and noise filters on SCL and SDA lines for enhanced signal integrity
• Self-timed erase/write cycles with automatic termination upon completion

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems utilizing I²C communication
• Parameter retention in battery-operated devices due to low power requirements
• Non-volatile memory backup for microcontroller applications

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) and 'SN' indicates the 8-Lead SOIC package. Confirm the specific revision of the datasheet DS20002118B matches the production lot requirements. Ensure compatibility with system voltage levels, noting the 1 MHz clock speed is valid across the full 1.7V to 5.5V range.

Memory IC Selection Notes

Select this component when high-speed I²C communication at 1 MHz is required alongside robust environmental tolerance. The 24FC16H differs from the 24LC16BH by supporting lower voltages (1.7V) and higher speeds. Consider the 8-pin SOIC footprint constraints and ensure adequate pull-up resistors are selected for the target bus frequency and capacitance.

Memory IC Part Context

This part belongs to the 24XX16H family of serial EEPROMs, which also includes the 24AA16H and 24LC16BH variants. While sharing similar memory architecture and interface protocols, the 24FC16H is distinguished by its ability to operate at 1 MHz clock speeds and support lower supply voltages starting at 1.7V, making it suitable for high-performance low-voltage applications.

Memory IC Replacement Considerations

The 24LC16H-E/SN may serve as a functional substitute if the application does not require the 1 MHz clock speed or 1.7V minimum voltage operation. Verify package pinout compatibility and temperature range specifications before substitution.
