Product details
Overview
FM24V01A-GTR from Infineon Technologies (formerly Cypress) is a 128-Kbit (16K × 8) serial I²C ferroelectric RAM (F-RAM) nonvolatile memory IC, designed as a hardware-compatible replacement for EEPROM in microcontroller-based data logging and industrial control systems. It delivers NoDelay™ writes, 10¹⁴ read/write endurance, and 151-year data retention at industrial temperature (–40 °C to +85 °C), operating from 2.0 V to 3.6 V.
For engineers reviewing the FM24V01A-GTR datasheet, FM24V01A-GTR pinout, FM24V01A-GTR application, or FM24V01A-GTR equivalent, key selection criteria include write-speed-critical nonvolatile storage, low-power rapid-write cycles, I²C bus timing compatibility (100 kHz/400 kHz/3.4 MHz), and SOIC-8 footprint constraints in embedded telemetry and sensor node designs.
Technical Context
The FM24V01A-GTR implements a two-wire I²C interface with slave-only operation, supporting standard-mode (100 kHz), fast-mode (400 kHz), and high-speed mode (3.4 MHz) - though it does not fully comply with NXP's Fast-mode Plus or High Speed Mode voltage hysteresis specifications. Its internal logic uses a 14-bit address space (16K × 8) with A0–A2 device-select inputs enabling up to eight devices on one bus.
Unlike EEPROM, it performs true byte-write operations at bus speed without internal write-cycle delays or polling; data is committed immediately after successful I²C byte transfer. The Device ID register provides manufacturer ID (0x01) and product ID (0x09), accessible via dedicated I²C command sequence.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C128C-SSHL-T | 128 Kbit I²C EEPROM; 1M write cycles; 10 ms write time; 1.7–5.5 V operation | Lacks NoDelay™ write; requires polling; higher write energy; wider VDD range | Select only when legacy EEPROM firmware exists and endurance <10⁶ cycles suffices |
| MB85RC128A-GE1 | 128 Kbit I²C FRAM; 10¹⁴ endurance; 1.8–3.6 V; 1 MHz max I²C speed | Same core benefits but lacks Device ID register and 3.4 MHz mode support | Prefer when Device ID verification is unnecessary and 400 kHz bus speed is sufficient |
Compared with AT24C128C-SSHL-T, FM24V01A-GTR eliminates write latency and extends lifetime by 100,000×; versus MB85RC128A-GE1, it adds Device ID and 3.4 MHz capability - critical for secure, high-throughput edge logging.

FAQ
Is FM24V01A-GTR pin-compatible with standard EEPROMs in SOIC-8 packages?
Yes - FM24V01A-GTR uses identical SOIC-8 pinout and I²C protocol timing for 100 kHz and 400 kHz modes, allowing direct PCB-level replacement of EEPROMs like AT24C128 without layout changes. WP, A0–A2, SDA, SCL, VDD, and VSS map identically. No firmware modification is needed for basic read/write operations.
Does FM24V01A-GTR require external circuitry for I²C bus termination?
Yes - SDA and SCL lines require external pull-up resistors. Recommended values are 2.2 kΩ for 100 kHz, 1 kΩ for 400 kHz, and 470 Ω for 3.4 MHz operation, calculated per bus capacitance and VOL/IOL specs in the datasheet. No level shifters or active drivers are needed for 3.3 V systems.
How is the Device ID accessed and what information does it provide?
The Device ID is read via a dedicated I²C command sequence: START → Slave Address (0xA0) → Device ID Command (0x06) → RESTART → Read 3 bytes. It returns Manufacturer ID (0x01), Product ID (0x09), and Revision ID (0x00), enabling automated BOM verification and firmware version-aware initialization.
Can FM24V01A-GTR operate reliably below 2.0 V?
No - the absolute minimum VDD is 2.0 V per datasheet specifications. Operation below this threshold risks incomplete writes, data corruption, or failure to enter sleep mode. For sub-2.0 V applications, consider voltage supervisors or power-path management to ensure clean brownout detection and controlled shutdown before VDD drops below specification.
