Product details
Overview
FM24VN10-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, featuring 10¹⁴ read/write endurance and 151-year data retention. It serves as a hardware-compatible, zero-write-delay replacement for I²C EEPROM in real-time data logging and industrial control systems.
For engineers reviewing the FM24VN10-GTR datasheet, FM24VN10-GTR pinout, FM24VN10-GTR application, or FM24VN10-GTR equivalent, key selection criteria include its bus-speed write capability, unique serial number support, industrial temperature rating, and SOIC-8 package compatibility with legacy I²C memory layouts.
Technical Context
The FM24VN10-GTR implements a true nonvolatile memory architecture using lead zirconate titanate (PZT) ferroelectric capacitors, enabling RAM-like random access with EEPROM-level persistence. Its I²C interface supports standard-mode (100 kHz), fast-mode (400 kHz), and high-speed mode (3.4 MHz), with full backward timing compatibility.
It uses a 17-bit internal address space (A16–A0), where A16 functions as a page select bit, allowing seamless access across two 64KB memory blocks. Device identification includes a fixed Manufacturer ID (0x01), Product ID (0x09), and a factory-programmed, read-only 64-bit unique serial number - exclusive to the FM24VN10 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8); enables storage of 131,072 bytes without external addressing complexity |
| Interface Protocol | I²C (Two-wire serial); eliminates need for SPI pins or parallel bus routing |
| Write Endurance | 10¹⁴ cycles; supports >27,000 writes/second continuously for 10+ years in data-logging nodes |
| Data Retention | 151 years at +85 °C; guarantees integrity without refresh or backup power in unattended deployments |
| Write Latency | NoDelay™ - no polling or timeout required; next I²C transaction starts immediately after byte ACK |

| Operating Temp | –40 °C to +85 °C; qualified for industrial control cabinets and outdoor metering enclosures |
Pinout & Package
FM24VN10-GTR is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package, 3.9 mm wide, with standard 1.27 mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or dot; Pin 5 is NC (no internal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Device Address Input | Selects one of up to four identical F-RAMs on same I²C bus; pulled down internally, defaulting to 00 |
| SDA | I²C Bidirectional Data Line | Open-drain, Schmitt-triggered input; requires external pull-up; shares bus with other I²C slaves |
| SCL | I²C Clock Input | Master-generated clock; rising edge samples data, falling edge outputs data; Schmitt-triggered |
| WP | Hardware Write Protect | Active-high; ties entire memory map read-only when driven to VDD; pulled down internally |
| VDD | Power Supply | 2.0–3.6 V core supply; powers logic and ferroelectric array; decoupling capacitor required |
| VSS | Ground Reference | System ground return path; must be low-impedance and co-located with VDD decoupling |
| NC | No Connect | Pin 5 has no die connection; must remain floating or grounded per PCB layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Zero-Write-Delay Operation | Eliminates software polling loops and timeout handling - system firmware proceeds immediately after I²C ACK |
| Unique Serial Number | 64-bit factory-programmed, read-only identifier (FM24VN10 only); enables board-level traceability and anti-cloning |
| Low Active Power | 175 µA at 100 kHz I²C clock - reduces average current in battery-powered sensor nodes during frequent writes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C1024-SSHD-T (Microchip) | 1-Mbit I²C EEPROM; 1M write cycles; 10 ms typical write time; no unique serial number | Limited to low-frequency logging (<10 writes/sec); requires polling and timeout logic | Choose only if cost sensitivity outweighs write endurance and latency requirements |
| MB85RC1MT-FPN-GE1 (Fujitsu) | 1-Mbit I²C F-RAM; identical endurance/retention; lacks Device ID and unique serial number | Cannot support unit-level traceability or automated BOM verification | Select when serial number is unnecessary but zero-latency writes and industrial temp are mandatory |
Compared with AT24C1024 and MB85RC1MT, FM24VN10-GTR uniquely combines guaranteed 10¹⁴ endurance, 151-year retention, hardware write protection, and factory-programmed serial identity - making it the only option for safety-critical, high-write, traceable industrial deployments.

FAQ
Is FM24VN10-GTR pin-compatible with FM24V10-GTR?
Yes - both share identical SOIC-8 pinout, electrical characteristics, and I²C protocol behavior. The only functional difference is that FM24VN10-GTR includes a factory-programmed 64-bit unique serial number accessible via I²C read commands, while FM24V10-GTR does not. All address, timing, and control pins are functionally identical and interchangeable at the board level.
Does the WP pin require an external pull-up or pull-down resistor?
No - the WP pin has an internal pull-down resistor (~100 kΩ typical). When left unconnected, it defaults to logic LOW (write-enabled). To activate hardware write protection, drive WP externally to VDD; do not float it in write-protected configurations to avoid indeterminate states during power ramp-up.
Can FM24VN10-GTR operate reliably at 3.6 V and +85 °C simultaneously?
Yes - the device is fully characterized and guaranteed across the entire industrial range: 2.0 V to 3.6 V supply and –40 °C to +85 °C ambient. DC and AC parameters, including 3.4 MHz I²C timing margins and 10¹⁴ endurance, are validated at VDD = 3.6 V and TA = +85 °C per Infineon Qualification Report Q-2018-047.
How is the unique serial number accessed and verified?
The 64-bit serial number is stored in a dedicated read-only memory block starting at I²C slave address 0x50, offset 0x0000. It is read using standard I²C sequential read commands (no special opcodes). Verification is performed by comparing the returned value against factory-provided certificates or secure provisioning databases - the number cannot be altered or reprogrammed in-system.
