Product details
Overview
FM24V05-GTR from Cypress Semiconductor is a 512-Kbit (64 K × 8) serial I²C ferroelectric RAM (F-RAM) providing nonvolatile data storage with RAM-like write performance, 10¹⁴ read/write endurance, and 151-year data retention at +85 °C. It operates from 2.0 V to 3.6 V across –40 °C to +85 °C and replaces I²C EEPROM in high-write-frequency applications such as industrial sensor logging and real-time metering.
For engineers reviewing the FM24V05-GTR datasheet, FM24V05-GTR pinout, FM24V05-GTR application, or FM24V05-GTR equivalent, key selection criteria include NoDelay™ write capability, I²C bus compatibility up to 3.4 MHz, WP-controlled hardware write protection, and SOIC-8 package integration in space-constrained embedded systems.
Technical Context
The FM24V05-GTR implements a true nonvolatile memory core using lead zirconate titanate (PZT) ferroelectric capacitors, enabling byte-level writes without erase cycles or write latency. Its I²C interface supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes, with full backward timing compatibility for legacy EEPROM firmware.
Internally, it uses a 16-bit address latch that auto-increments during sequential transfers, supports random-access reads after dummy-write addressing, and incorporates a fixed 0xA0–0xA7 slave address range determined by A2–A0 pins. Device ID includes manufacturer ID (0x01) and product ID (0x50), accessible via dedicated I²C command.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 512 Kbit (64 K × 8); supports full byte-addressable access without page boundaries or erase blocks. |
| Write Endurance | 10¹⁴ cycles; enables continuous logging at 100 Hz for >31 years without wear-out failure. |
| Data Retention | 151 years at +85 °C; eliminates periodic refresh or backup power requirements in sealed industrial deployments. |
| I²C Speed | Up to 3.4 MHz (Hs-mode); reduces 64 KB write time to <200 ms vs >20 s for equivalent EEPROM. |
| Supply Voltage | 2.0 V to 3.6 V; interoperable with 2.5 V and 3.3 V microcontroller I/O domains without level shifting. |
| Operating Temp | –40 °C to +85 °C; qualified for industrial control cabinets and outdoor metering enclosures. |
| Active Current | 175 µA at 100 kHz; minimizes average power in battery-backed data capture nodes. |
Pinout & Package
FM24V05-GTR is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant footprint, and RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A2 | Device Select Input | Three LSBs of I²C slave address (0xA0–0xA7); enable up to 8 devices on same bus without address conflict. |
| SDA | Bi-directional Data Line | Open-drain I²C data line with Schmitt-trigger input and slope-controlled output; requires external pull-up. |
| SCL | Clock Input | Master-generated I²C clock with Schmitt-trigger input; defines timing for all read/write transfers. |
| WP | Hardware Write Protect | Active-high pin; when tied to VDD, disables all write operations including Device ID reads - prevents accidental overwrites. |
| VDD | Power Supply | Primary 2.0–3.6 V supply; powers internal logic and F-RAM array; no internal charge pump required. |
| VSS | Ground Reference | System ground return path; must be low-impedance connection to ensure noise immunity during high-speed I²C operation. |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ Writes | Zero-latency byte writes: data committed immediately upon ACK; eliminates polling loops and bus blocking in real-time firmware. |
| Ferroelectric Core | Nonvolatile storage without charge pumps or high-voltage generators; reduces system EMI and simplifies power design. |
| I²C Drop-in Replacement | Pin- and protocol-compatible with standard 64 K × 8 I²C EEPROMs (e.g., AT24C512); requires no firmware changes for migration. |
| Low-Power Sleep Mode | 5 µA typical sleep current; enables always-on logging nodes with multi-year coin-cell battery life. |
| Device ID Register | Read-only 16-bit ID (0x0150) confirming Cypress origin and FM24V05 revision; supports automated BOM validation in production test. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C512B-PU | 512-Kbit I²C EEPROM; 1 million write cycles; 10 ms write latency per byte; requires polling. | Lower endurance and slower writes limit use to infrequent configuration storage - unsuitable for high-frequency logging. | Select only where cost is primary constraint and write frequency <1000 cycles/day. |
| MB85RC512T | 512-Kbit I²C F-RAM (Fujitsu); identical density and endurance; supports 1 MHz max I²C speed; no Device ID register. | Lacks manufacturer/product ID verification - limits traceability in regulated medical/automotive BOMs. | Prefer when I²C speed ≤1 MHz suffices and Device ID is not required for audit compliance. |
Compared with AT24C512B-PU and MB85RC512T, FM24V05-GTR uniquely combines 3.4 MHz I²C support, integrated Device ID, and Cypress's industrial qualification - making it optimal for safety-critical, high-throughput, and auditable embedded systems.

FAQ
Is FM24V05-GTR pin-compatible with standard I²C EEPROMs like AT24C512?
Yes - FM24V05-GTR uses identical SOIC-8 pinout, I²C slave address mapping (A2–A0), and protocol timing for 100 kHz and 400 kHz modes. No PCB redesign or firmware modification is needed for drop-in replacement, though Hs-mode (3.4 MHz) requires master-side enablement.
Does FM24V05-GTR require external circuitry for write protection?
No - the WP pin provides hardware-level write protection when pulled high to VDD. When WP = VDD, all memory locations and Device ID reads are locked; no external logic or resistors are required beyond the standard I²C pull-ups on SDA/SCL.
How does FM24V05-GTR achieve 151-year data retention at +85 °C?
This value is derived from accelerated retention testing per JESD22-A117, extrapolated using the Arrhenius model. The ferroelectric PZT capacitor retains polarization state without leakage-driven decay, unlike floating-gate EEPROM - enabling guaranteed data integrity over 151 years at maximum operating temperature.
Can FM24V05-GTR operate reliably below 2.0 V?
No - the absolute minimum VDD is 2.0 V per datasheet specifications. Below this threshold, internal logic may fail to decode I²C commands or commit writes correctly. For sub-2.0 V operation, consider Cypress's FM24V01 (1.8 V min) or verify actual behavior under your specific load conditions.
