Product details

Overview

FM25V10-G from Cypress Semiconductor is a 1-Mbit (128K × 8) serial SPI 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, supports 40-MHz SPI (modes 0 and 3), and replaces serial EEPROM/flash in high-write-cycle data logging systems.

For engineers reviewing the FM25V10-G datasheet, FM25V10-G pinout, FM25V10-G application, or FM25V10-G equivalent, key selection criteria include write latency independence from bus speed, hardware/software write protection granularity (1/4, 1/2, full array), unique serial number (FM25VN10 variant), and industrial-grade reliability without wear leveling overhead.

Technical Context

The FM25V10-G implements a synchronous SPI slave interface with zero-latency write execution: data commits immediately upon byte transfer completion-no polling or internal write cycles required. Its ferroelectric memory array eliminates charge-pump-based programming delays inherent in flash/EEPROM.

It integrates dual write protection layers: hardware-level WP pin control (active-low, tied to VDD if unused) and software-configurable status register bits enabling block-level protection. The device also embeds read-only Manufacturer ID, Product ID, and (in FM25VN10) a unique 64-bit serial number for system traceability.

Key Specifications

Pinout & Package

FM25V10-G 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 share identical pin functions and electrical behavior.

Pin/Terminal	Circuit Role	Design Meaning
CS	Chip Select input	Active-low enable; places device in standby (90 µA) when HIGH; must fall before each opcode
SCK	Serial clock input	Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–40 MHz, interruptible
SI	Serial input	Receives opcodes, addresses, and write data; sampled on SCK rising edge; must be driven valid
SO	Serial output	Drives read data and status on SCK falling edge; 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 when LOW; requires SCK LOW during transition; internal weak pull-up
VDD	Power supply	2.0–3.6 V core and I/O supply; decoupling capacitor required per layout guidelines
VSS	Ground	Reference return path; must connect to system ground plane with low-inductance routing

Key Features

Feature	Design Value
NoDelay™ write architecture	Eliminates write latency and polling loops-data commits at bus speed, enabling deterministic real-time logging
Ferroelectric memory process	Enables 10¹⁴ endurance and 151-year retention without oxide degradation mechanisms of flash/EEPROM
Dual write protection	Hardware (WP pin) + software (status register) control over 1/4, 1/2, or full memory array locking
Unique serial number (FM25VN10)	64-bit factory-programmed read-only identifier for board-level serialization and anti-counterfeiting
SPI mode compatibility	Supports both Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) for drop-in replacement in legacy designs

Applications

Industrial Data Logger

Smart Meter Firmware Storage

Use Scenario: Continuous timestamped sensor readings (e.g., temperature, pressure) written every 100 ms in harsh environments.

IC Role / Device Role / Timing Role: Nonvolatile scratchpad memory handling rapid, unbuffered writes without data loss during power interruption.

Use Value: 10¹⁴ endurance ensures >30 years of operation at 100 Hz write rate; no wear leveling firmware required.

Use Scenario: Storing tariff tables, calibration coefficients, and usage history in electricity/water meters with infrequent firmware updates.

IC Role / Device Role / Timing Role: SPI-bootable configuration store accessed by metering SoC during cold start and runtime parameter lookup.

Use Value: 40-MHz SPI interface enables sub-millisecond coefficient reads; hardware WP prevents accidental corruption during field updates.

Automotive Body Control Module

Medical Diagnostic Equipment

Use Scenario: Recording door lock actuation counts, seat position memory, and error logs in 12 V automotive systems with wide voltage transients.

IC Role / Device Role / Timing Role: Fail-safe event logger interfacing directly to CAN-connected MCU via SPI, surviving load-dump conditions.

Use Value: 2.0–3.6 V operation tolerates brown-out events; 151-year retention preserves warranty-critical logs across vehicle lifetime.

Use Scenario: Capturing patient ECG waveforms and diagnostic settings in portable ultrasound or defibrillators requiring FDA-compliant data integrity.

IC Role / Device Role / Timing Role: High-reliability buffer between ADC subsystem and ARM Cortex-M host, ensuring lossless waveform capture during battery switchover.

Use Value: NoDelay™ writes guarantee zero-sample-drop acquisition at 1 kHz sampling; RoHS compliance meets medical regulatory requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar nonvolatile serial 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 serial number	Acceptable for infrequent firmware updates but unsuitable for high-frequency data logging due to write latency	Select only if cost-per-bit is primary and write frequency < 10×/hour
BR24G128FJ-WE2	128-Kbit I²C EEPROM; 1 MHz max clock; 1M write cycles; 200 ms write time; VDD = 1.7–5.5 V	Limited bandwidth and endurance make it inadequate for continuous logging; better for static configuration storage	Choose for ultra-low-power sleep mode (< 1 µA) where write speed and cycle count are secondary

Compared with AT25DF041A-SSH-T and BR24G128FJ-WE2, FM25V10-G delivers 100 million× higher endurance and eliminates write latency-critical for deterministic data capture-but trades off higher unit cost and lower density than flash alternatives.

FAQ

Is FM25V10-G pin-compatible with standard SPI EEPROMs or flash devices?

Yes-FM25V10-G uses an industry-standard 8-pin SOIC or DFN package with identical pinout (CS, SCK, SI, SO, WP, HOLD, VDD, VSS) and SPI command set as common serial EEPROMs and flash. It supports SPI modes 0 and 3, enabling direct hardware replacement without PCB redesign.

Does FM25V10-G require special initialization or firmware drivers?

No-FM25V10-G behaves electrically and logically like a standard SPI memory device. Standard SPI read/write opcodes (0x03, 0x02) are used; no special initialization sequence or wear-leveling driver is needed. Its NoDelay™ writes simplify firmware by removing polling loops and timeout handling.

What is the function of the HOLD pin, and when should it be used?

The HOLD pin suspends ongoing memory operations (read or write) when pulled LOW, allowing the host MCU to service higher-priority interrupts without data corruption. Transitions must occur while SCK is LOW. It is commonly used in real-time systems where deterministic response to external events is critical.

How does FM25V10-G achieve 151-year data retention at +85 °C?

This retention is guaranteed by Cypress's ferroelectric capacitor technology, which stores data as polarization states in lead zirconate titanate (PZT) film-not trapped charge in floating gates. Unlike flash/EEPROM, PZT polarization decay follows Arrhenius kinetics with extremely low activation energy, enabling multi-century retention at elevated temperatures.
