Product details
Overview
FM24V02A-GTR from Cypress Semiconductor is a 256-Kbit (32K × 8) serial I²C ferroelectric RAM (F-RAM) with NoDelay™ writes, 10¹⁴ read/write endurance, and 151-year data retention. It operates from 2.0 V to 3.6 V across –40 °C to +85 °C and replaces serial EEPROM in high-write-frequency applications such as industrial data logging and real-time metering.
For engineers reviewing the FM24V02A-GTR datasheet, FM24V02A-GTR pinout, FM24V02A-GTR application, or FM24V02A-GTR equivalent, key selection criteria include write-speed equivalence to SRAM, I²C bus compatibility at up to 3.4 MHz, low active current (175 µA @ 100 kHz), and hardware-level write protection via the WP pin.
Technical Context
The FM24V02A-GTR implements a true nonvolatile memory architecture using lead zirconate titanate (PZT) ferroelectric capacitors, enabling byte-level writes without erase cycles or write delays. Its I²C interface supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes - though it does not fully comply with NXP's Fast-mode Plus or High-Speed Mode voltage hysteresis specifications.
Internally, the device uses a 15-bit address latch for sequential and random access, with automatic incrementation after each byte transfer. Device ID (manufacturer and product ID) is read-only and accessible via dedicated I²C commands, supporting multi-device bus configuration using A0–A2 address pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 256 Kbit (32,768 × 8), directly addressable without page boundaries or erase overhead |
| Interface | I²C two-wire, compatible with legacy 100/400 kHz timing and extended to 3.4 MHz in Hs-mode |
| Write Endurance | 10¹⁴ cycles - enables continuous logging at 100 Hz for >31 years without wear-out |
| Data Retention | 151 years at +85 °C - eliminates periodic refresh or backup power requirements |
| Supply Voltage | 2.0 V to 3.6 V - interoperable with 2.5 V and 3.3 V microcontroller I/O domains |
| Operating Temp | –40 °C to +85 °C - qualified for industrial control and smart metering environments |
| Active Current | 175 µA at 100 kHz - reduces system power budget vs. EEPROM (typically >1 mA during write) |
Pinout & Package
FM24V02A-GTR is housed in an 8-pin SOIC package (5.3 mm × 5.3 mm, 1.27 mm pitch), RoHS-compliant and optimized for automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A2 | Device Select Input | Three LSBs of slave address; enable up to eight devices on same I²C bus; internally pulled down |
| SDA | Bidirectional Data Line | Open-drain I²C data line with Schmitt trigger input and slope-controlled output; requires external pull-up |
| SCL | Clock Input | Master-generated clock; rising edge samples input, falling edge outputs data; Schmitt-triggered for noise immunity |
| WP | Hardware Write Protect | High = full memory write-protected; low = write enabled; internally pulled down for default-enable behavior |
| VDD | Power Supply | 2.0–3.6 V supply; powers internal logic and F-RAM array; decoupling capacitor required |
| VSS | Ground Reference | System ground return path; must be low-impedance and co-located with VDD decoupling |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C256B-SSHL-T | 256-Kbit I²C EEPROM; 1M write cycles; 10 ms typical write time; 5.5 V max VDD | Lacks NoDelay™; requires polling or fixed delays; unsuitable for >10 Hz write rates | Select only when cost sensitivity outweighs write endurance and latency requirements |
| MB85RC256V | 256-Kbit I²C F-RAM; identical 10¹⁴ endurance and 151-yr retention; 2.7–5.5 V supply range | Wider VDD range enables direct use with 5 V microcontrollers; same pinout but different device ID | Preferred for 5 V systems or where Cypress supply continuity is constrained |
Compared with AT24C256B-SSHL-T, FM24V02A-GTR delivers 100,000× higher endurance and eliminates write latency; versus MB85RC256V, it offers tighter voltage tolerance (2.0–3.6 V) and Cypress-specific device ID support for legacy firmware compatibility.

FAQ
Is FM24V02A-GTR pin-compatible with standard 256-Kbit I²C EEPROMs like AT24C256?
Yes - FM24V02A-GTR uses an industry-standard 8-pin SOIC package with identical pin assignments (A0–A2, SDA, SCL, WP, VDD, VSS) and I²C protocol framing. No PCB redesign is needed for drop-in replacement, though firmware must disable EEPROM polling routines due to NoDelay™ operation.
Does FM24V02A-GTR support standard I²C clock stretching?
No - the FM24V02A-GTR does not implement clock stretching. It completes all internal operations within the I²C bus timing window, relying on its inherent zero-write-delay architecture. Host software must adhere to standard I²C timing without expecting SCL hold periods.
What is the maximum supported I²C bus speed, and are there timing caveats?
The FM24V02A-GTR supports up to 3.4 MHz in High-Speed Mode (Hs-mode), but it does not meet NXP's I²C specification for VHYS in Hs-mode or IOL in Fast-mode Plus. Designers must verify signal integrity and use appropriate pull-up strength (RPmin = (VDD – VOLmax)/IOL) per the datasheet.
How is write protection implemented, and can it be overridden in-system?
Write protection is controlled solely by the WP pin: tied to VDD for full memory lock, grounded for full write enable. There is no software-configurable lock or sector protection. The pin is internally pulled down, so floating WP defaults to write-enabled mode - no firmware initialization is required.
