Infineon Technologies FM24V10-GTR

Overview

FM24V10-GTR from Infineon Technologies (formerly Cypress) is a 1-Mbit serial I²C ferroelectric RAM (F-RAM), logically organized as 128K × 8, operating from 2.0 V to 3.6 V over –40 °C to +85 °C. It delivers NoDelay™ writes, 10¹⁴ read/write endurance, and 151-year data retention-enabling high-frequency data logging in industrial controllers and smart meters where EEPROM latency causes data loss.

For engineers reviewing the FM24V10-GTR datasheet, FM24V10-GTR pinout, FM24V10-GTR application, or FM24V10-GTR equivalent, key selection criteria include I²C bus speed compatibility (up to 3.4 MHz), write-protection via WP pin, device addressing using A2/A1 pins, and SOIC-8 package integration into space-constrained embedded systems.

Technical Context

The FM24V10-GTR implements a true nonvolatile memory core using lead zirconate titanate (PZT) ferroelectric capacitors, enabling RAM-like random access with zero write latency-no internal write cycle or polling required. Its I²C interface supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes while maintaining full backward compatibility with legacy EEPROM timing.

Memory addressing uses a 17-bit scheme: one page-select bit (A16) plus 16 address bits, allowing seamless access across the full 128K-byte array. Device identification includes fixed Manufacturer ID (0x01) and Product ID (0x09), plus optional unique serial number (FM24VN10 variant only).

FAQ

Is FM24V10-GTR pin-compatible with standard I²C EEPROMs like AT24C1024?

Yes-FM24V10-GTR uses an 8-pin SOIC package with identical pinout (VDD, VSS, SDA, SCL, WP, A1, A2, NC) and I²C slave address structure (0xA0–0xA7). No PCB redesign is needed; only firmware timing adjustments may be required to remove EEPROM polling loops.

Does FM24V10-GTR require external high-voltage circuitry for writes like EEPROM?

No-FM24V10-GTR performs all writes using standard VDD supply voltage (2.0–3.6 V); no internal charge pump or elevated voltage generation is used. This eliminates EEPROM-style write power spikes and simplifies power design in battery-operated systems.

Can the WP pin be left unconnected, or must it be actively driven?

WP is internally pulled down; leaving it unconnected results in write-enabled operation. For robust protection, tie WP directly to VDD (write-protected) or VSS (write-enabled)-do not float in noise-sensitive environments. External pull-up/down resistors are unnecessary unless board-level noise mitigation is required.

What is the maximum I²C clock frequency supported, and does it require special timing setup?

FM24V10-GTR supports up to 3.4 MHz in high-speed mode, but standard 400 kHz operation requires no special configuration. The device automatically detects bus speed via SCL timing; no register programming or mode selection is needed-ensuring plug-and-play compatibility with existing I²C masters.
