Product details

Overview

FM25V02A-GTR from Infineon Technologies (formerly Cypress) is a 256-Kbit serial SPI F-RAM organized as 32K × 8, delivering NoDelay™ writes, 10¹⁴ read/write endurance, and 151-year data retention at industrial temperature (–40 °C to +85 °C). It operates from 2.0 V to 3.6 V and supports 40-MHz SPI bus speeds in modes 0 and 3 - enabling real-time nonvolatile logging in energy-constrained industrial sensors.

For engineers reviewing the FM25V02A-GTR datasheet, FM25V02A-GTR pinout, FM25V02A-GTR application, or FM25V02A-GTR equivalent, key selection criteria include write-cycle latency, SPI timing compatibility with legacy EEPROM/flash interfaces, hardware/software write protection granularity, and low-quiescent-current operation in sleep mode (8 µA).

Technical Context

The FM25V02A-GTR implements a ferroelectric memory array with zero-write-latency architecture: data commits immediately upon byte transfer completion, eliminating polling and timeout handling. Its SPI interface natively supports dual clock modes (0 and 3), with inputs latched on SCK rising edge and outputs driven on falling edge.

Write protection is implemented via three independent mechanisms: hardware WP pin control (active-low), software WREN/WRDI instructions, and configurable block protection (1/4, 1/2, or full array) managed through a nonvolatile status register - all guaranteed across –40 °C to +85 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	256 Kbit (32K × 8) - supports full byte-addressable access without page management overhead
Write endurance	10¹⁴ cycles - enables >27,000 writes/sec for 10 years in continuous data-logging systems
Data retention	151 years at +85 °C - eliminates periodic refresh or backup power requirements
SPI speed	Up to 40 MHz - matches high-speed microcontroller SPI peripherals without clock stretching
Supply voltage	2.0 V to 3.6 V - interoperable with 2.5 V and 3.3 V logic domains without level shifters
Standby current	150 µA - suitable for battery-backed systems requiring months of retention between wake events
Sleep current	8 µA - enables multi-year operation on coin-cell batteries in remote sensor nodes

Pinout & Package

FM25V02A-GTR is available in two RoHS-compliant packages: 8-pin SOIC (3.9 mm × 4.9 mm) and 8-pin DFN (2 mm × 3 mm) with exposed pad (NC). Both packages share identical pin functions and ordering code suffix "-GTR" denotes tape-and-reel packaging.

Pin/Terminal	Circuit Role	Design Meaning
CS	Chip Select input	Active-low enable: pulls device out of standby; falling edge initiates opcode sequence
SCK	Serial clock input	Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–40 MHz
SI	Serial input	Receives opcodes, addresses, and write data; must be driven to valid logic level for IDD compliance
SO	Serial output	Drives read data and status bits; tristated when CS HIGH or HOLD LOW
WP	Write protect input	Hardware lock for status register writes when WPEN = 1; must tie to VDD if unused
HOLD	Operation suspend input	Pauses ongoing read/write without losing internal state; transitions only allowed while SCK = LOW
VSS	Ground	Reference return path for all digital and analog circuitry; requires low-impedance PCB connection
VDD	Power supply	Primary supply rail (2.0–3.6 V); powers core logic, F-RAM array, and I/O buffers

Key Features

Feature	Design Value
NoDelay™ write architecture	Eliminates write polling and timeout firmware overhead - each byte commits before next SPI cycle begins
Ferroelectric memory process	Enables 100 million × higher endurance than EEPROM without wear-leveling firmware
Dual SPI mode support	Interoperates with existing Mode 0 and Mode 3 masters - no hardware or driver modification required
Three-tier write protection	Combines pin-based, instruction-based, and block-level locking to prevent accidental overwrites in field-deployed systems
Device ID register	Manufacturer ID (0x01) and Product ID (0x20) readable via RDID command - enables automatic BOM validation during boot

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial nonvolatile memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AT25DF041A-SSH-T	4-Mbit SPI flash; requires 25 ms page-program time; 100k write cycles; no built-in block protection	Lacks real-time write capability; unsuitable for high-frequency logging or power-fail-safe buffering	Select only when cost-per-bit dominates and write frequency is <100×/day
BR24G256FJ-WE2	256-Kbit I²C EEPROM; 1 MHz max clock; 400k write cycles; 100-year retention at 25 °C	Slower interface; limited to 1 MHz; no HOLD pin; lower endurance and retention at elevated temperatures	Prefer for space-constrained designs where I²C is already used and write rate is ≤10 Hz

Compared with AT25DF041A-SSH-T and BR24G256FJ-WE2, FM25V02A-GTR uniquely delivers bus-speed writes, 10¹⁴ endurance, and guaranteed 151-year retention at +85 °C - making it the only option for deterministic, high-cycle, wide-temperature nonvolatile storage without firmware complexity.

FAQ

Is FM25V02A-GTR a direct hardware replacement for standard SPI EEPROMs?

Yes - FM25V02A-GTR uses identical 8-pin SOIC/DFN footprints and pinout as common 256-Kbit SPI EEPROMs (e.g., AT25020, M95256), supports SPI modes 0 and 3, and requires no changes to PCB layout or driver initialization. Its NoDelay™ writes eliminate wait-state handling needed for EEPROM page programming.

How does the HOLD pin function during an active memory operation?

When HOLD is pulled LOW during any memory operation (read, write, or status access), the FM25V02A-GTR suspends the transaction immediately, retains internal address and state, and tri-states SO. The operation resumes on the next rising edge of SCK after HOLD returns HIGH - enabling CPU context switching without data loss or reinitialization.

What is the role of the EXPOSED PAD in the DFN package?

The EXPOSED PAD on the 8-pin DFN package is electrically unconnected (NC) and thermally isolated from the die. It must not be soldered to the PCB ground plane, as doing so risks shorting internal bond wires. Infineon specifies it as a mechanical anchor only - no thermal or electrical benefit is provided by connecting it.

Can FM25V02A-GTR be used in systems powered by a 1.8 V supply?

No - FM25V02A-GTR requires a minimum VDD of 2.0 V per its absolute maximum ratings and DC characteristics. Operation below 2.0 V may result in undefined behavior, failed writes, or premature data loss. For 1.8 V systems, consider Infineon's parallel-interface FM24CL64 or alternate low-voltage F-RAM families with validated 1.7–1.95 V operation.
