FM3164-GTR

Specialized ICS Overview

The FM3164-GTR is a 64-Kbit Integrated Processor Companion with Ferroelectric Random Access Memory (F-RAM), manufactured by Infineon Technologies. It integrates nonvolatile memory, a real-time clock (RTC), and processor supervisor functions into a single 14-pin SOIC package. The device operates within a voltage range of 2.7 V to 5.5 V and supports an I2C interface frequency up to 1 MHz. Key features include high endurance of 10^14 read/write cycles, 151-year data retention, a programmable watchdog timer, low-voltage reset, and early power-fail warning capabilities. It is designed for industrial temperature ranges from -40 °C to +85 °C.

Specialized ICS Feature Summary

• Integrates 64-Kbit F-RAM with NoDelay writes and 10^14 write endurance
• Includes Real-Time Clock/Calendar with software calibration and battery backup support
• Features processor companion functions: low-VDD reset, watchdog timer, and event counters
• Supports I2C interface with up to 1 MHz speed and multiple device addressing

Specialized ICS Applications

• Processor-based systems requiring integrated nonvolatile memory and timing
• Industrial control systems needing robust power-fail detection and reset management
• Data logging applications requiring high endurance and long-term data retention

Specialized ICS Procurement Notes

Verify the specific ordering suffix and package variant against the official Infineon datasheet before procurement. Confirm that the 14-SOIC package meets the PCB layout requirements. Ensure compatibility with the system's I2C bus voltage levels and crystal specifications for the RTC function. Check for any end-of-life notices or alternative part recommendations from the manufacturer.

Specialized ICS Selection Notes

Select the FM3164-GTR when a combined solution for serial nonvolatile memory, real-time clock, and system supervision is required. Consider this component for designs where board space is limited and multiple discrete components would otherwise be needed. Ensure the application utilizes the I2C interface correctly and provides appropriate backup power to the VBAK pin if continuous timekeeping is necessary.

Specialized ICS Part Context

The FM3164-GTR belongs to the FM3164/FM31256 family of Integrated Processor Companions with F-RAM. This family combines ferroelectric memory with essential system management functions. The FM3164 specifically offers 64 Kbits of memory, whereas the FM31256 variant provides 256 Kbits. Both share similar functional blocks including the RTC and supervisor circuits.
