FM24C16B-G1

Memory IC Overview

The FM24C16B-G1 is a 16-Kbit nonvolatile ferroelectric random access memory (F-RAM) logically organized as 2 K × 8 bits. It utilizes an advanced ferroelectric process to provide high-endurance of 10^14 read/write cycles and 151-year data retention. The device features NoDelay™ writes, eliminating internal write cycles. It operates with a fast 2-wire serial interface (I2C) supporting up to 1-MHz frequency and direct hardware replacement for serial EEPROMs. Power consumption includes 100 µA active current at 100 kHz and 4 µA typical standby current. Operating voltage ranges from 4.5 V to 5.5 V, with industrial temperature coverage from –40 °C to +85 °C in an 8-pin SOIC package.

Memory IC Feature Summary

• High endurance of 10^14 read/write cycles
• NoDelay™ writes without internal write cycles
• Direct hardware replacement for serial I2C EEPROMs
• Low power consumption with 4 µA typical standby current

Memory IC Applications

• Industrial control systems requiring frequent data logging
• Smart meters and utility instrumentation
• Automotive electronic control units
• Medical devices needing reliable nonvolatile storage

Memory IC Procurement Notes

Verify the specific suffix 'G1' against official Infineon or Cypress datasheets, as standard documentation typically lists 'G' for RoHS compliance. Confirm pinout compatibility if substituting for legacy EEPROMs. Ensure supply chain sources are authorized distributors to guarantee component authenticity and traceability.

Memory IC Selection Notes

Select this component when high write endurance and zero-write-delay are critical compared to traditional EEPROMs. It is suitable for applications requiring frequent parameter updates or data logging. Consider the 1-MHz I2C speed and 5V operation range. Verify that the 8-pin SOIC package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the FM24C series of F-RAM memories originally developed by Ramtron International Corporation, which was acquired by Cypress Semiconductor and later became part of Infineon Technologies. The series is designed to replace EEPROMs in applications demanding higher reliability and faster write speeds.

Memory IC Replacement Considerations

Officially documented substitutes include FM24C16B and FM24C16B-G. Verify pin compatibility and electrical specifications before replacing.
