Product details
Overview
FM24VN10-G from Infineon Technologies (formerly Cypress) is a 1-Mbit serial I²C ferroelectric RAM (F-RAM), logically organized as 128K × 8, operating at 2.0–3.6 V over –40 °C to +85 °C, featuring 10¹⁴ read/write endurance, 151-year data retention, and NoDelay™ write capability - deployed in industrial data loggers for high-frequency sensor timestamping.
For engineers reviewing the FM24VN10-G datasheet, FM24VN10-G pinout, FM24VN10-G application, or FM24VN10-G equivalent, key selection criteria include I²C bus compatibility (up to 3.4 MHz), hardware drop-in replacement for EEPROM, unique serial number support, and low-power sleep mode (5 µA typical).
Technical Context
The FM24VN10-G implements a true nonvolatile memory architecture using lead zirconate titanate (PZT) ferroelectric capacitors, enabling RAM-like random access with EEPROM-level persistence. It requires no internal charge pump or write-cycle delay, eliminating polling and reducing system latency during frequent writes.
Its I²C interface supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes, with full backward timing compatibility and built-in Schmitt-trigger inputs on SDA/SCL for noise immunity. The device uses a 17-bit address space (1 page-select bit + 16-bit offset) and includes dedicated Device ID and factory-programmed unique serial number registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 1 Mbit (128K × 8) - supports up to 131,072 distinct byte-addressable locations without page boundaries limiting write size. |
| Interface | I²C (two-wire serial) - direct hardware replacement for EEPROM; compatible with legacy 100/400 kHz and high-speed 3.4 MHz timing. |
| Endurance | 10¹⁴ read/write cycles - enables continuous logging at 100 Hz for >31 years without wear-out failure. |
| Data retention | 151 years at +85 °C - guaranteed nonvolatile storage without refresh or backup power. |
| Supply voltage | 2.0 V to 3.6 V - interoperable with 3.3 V microcontrollers and battery-powered industrial sensors. |
| Operating temperature | –40 °C to +85 °C - qualified for uncontrolled industrial environments including motor control cabinets and outdoor metering. |
| Standby current | 90 µA (typ) - reduces quiescent power in always-on monitoring nodes. |
Pinout & Package
FM24VN10-G is housed in an 8-pin small outline integrated circuit (SOIC) package with gull-wing leads, RoHS-compliant, JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Device select address inputs | Set lower two bits of slave address (1010xxR/W); allow up to four devices on same I²C bus without address conflict. |
| SDA | Serial data/address bidirectional line | Open-drain I²C data line with Schmitt trigger input; requires external pull-up; supports multi-master arbitration. |
| SCL | Serial clock input | Master-generated clock; rising edge samples data, falling edge outputs data; Schmitt-triggered for robust timing. |
| WP | Write protect input | Hardware lock: tied to VDD disables all writes; tied to VSS enables full memory access; internal pull-down. |
| VDD | Power supply | Primary 2.0–3.6 V supply; powers logic and F-RAM array; decoupling capacitor required near pin. |
| VSS | Ground reference | System ground return path; must be low-impedance connection to minimize noise coupling into SDA/SCL. |
| NC | No connect | Internally unconnected pin; must remain floating or grounded per layout best practice; no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write operation | Writes complete within I²C bus cycle time - eliminates software polling and prevents data loss during power interruption. |
| Ferroelectric memory cell | Nonvolatile storage without charge pump or high-voltage programming - reduces system power by >90% vs. EEPROM during writes. |
| Unique serial number | Factory-programmed, read-only 64-bit identifier - enables board-level traceability and secure firmware binding. |
| Industrial-grade qualification | Tested across –40 °C to +85 °C with full DC/AC specs guaranteed - suitable for deployment in DIN-rail mounted PLCs and field instrumentation. |
| Device ID register | Read-only Manufacturer ID (0x01), Product ID (0x08), and Revision ID - allows runtime identification and firmware version matching. |

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; 1 million write cycles; 10 ms write time; 1.7–5.5 V operation. | Lacks unique serial number and NoDelay™; requires polling; higher write energy. | Select only if cost sensitivity outweighs write endurance and latency requirements. |
| MB85RC1MT-PFV-G-BND-ERE1 (Fujitsu) | 1-Mbit I²C F-RAM; identical 10¹⁴ endurance and 151-year retention; same SOIC-8 package; 2.7–3.6 V only. | Narrower VDD range excludes 2.0–2.6 V systems; no factory-programmed serial number. | Preferred for 3.3 V-only designs where serial number is not required; pin-compatible but voltage-limited. |
Compared with AT24C1024 and MB85RC1MT, FM24VN10-G uniquely combines ultra-wide voltage range (2.0–3.6 V), factory-unique serial number, and guaranteed industrial temperature operation - making it optimal for mixed-voltage embedded systems requiring traceability and deterministic write timing.

FAQ
Is FM24VN10-G pin-compatible with standard I²C EEPROMs like AT24C1024?
Yes - FM24VN10-G uses the same 8-pin SOIC package and identical I²C pinout (VDD, VSS, SDA, SCL, WP, A1, A2, NC), enabling direct PCB-level replacement without layout changes. Its slave address format (1010xxR/W) matches industry-standard EEPROM addressing, and it supports identical I²C timing modes including legacy 100 kHz and 400 kHz.
Does FM24VN10-G require external circuitry beyond standard I²C pull-ups?
No - beyond standard 2.2–10 kΩ pull-up resistors on SDA and SCL, no additional components are needed. The WP pin has an internal pull-down, A1/A2 pins are internally pulled down, and the NC pin requires no connection. Decoupling capacitance (100 nF ceramic) near VDD is recommended but not part of the interface circuitry.
How is the unique serial number accessed and what format does it use?
The 64-bit unique serial number is stored in a dedicated read-only register block starting at I²C address 0xFA. It is factory-programmed and immutable; accessed via standard I²C sequential read after sending the 0xFA address byte. Format is eight contiguous bytes (MSB first), providing globally unique identification per unit for anti-counterfeiting and firmware binding.
Can FM24VN10-G operate reliably during brief power interruptions common in industrial settings?
Yes - because writes complete within the I²C bus cycle (NoDelay™), FM24VN10-G guarantees data integrity even if VDD drops below specification mid-transaction. Unlike EEPROM, no internal write cycle is in progress when the bus releases control, so no data corruption or partial writes occur. This makes it suitable for brownout-prone environments such as factory floor controllers.
