Product details

Overview

FM25V10-GTR 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 at up to 40 MHz over 2.0–3.6 V, supports SPI modes 0 and 3, and replaces serial flash/EEPROM in real-time data logging systems requiring rapid nonvolatile writes.

For engineers reviewing the FM25V10-GTR datasheet, FM25V10-GTR pinout, FM25V10-GTR application, or FM25V10-GTR equivalent, key selection criteria include write latency (zero wait states), industrial temperature range (–40°C to +85°C), hardware/software write protection, unique serial number capability (FM25VN10 variant), and RoHS-compliant 8-pin SOIC/DFN packaging.

Technical Context

The FM25V10 implements a synchronous SPI slave interface with no internal write cycles or polling-data commits immediately upon byte transfer completion. Its ferroelectric memory array eliminates erase-before-write overhead and enables true byte-level random access without block management.

It integrates a nonvolatile status register with configurable block protection (1/4, 1/2, or full array), hardware WP pin control, and device identification logic delivering manufacturer ID, product ID, and (on FM25VN10) a factory-programmed unique serial number.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	1 Mbit (128K × 8); supports byte-serial read/write without address alignment constraints
Interface	SPI slave, modes 0 and 3; compatible with standard MCU hardware SPI peripherals
Max Clock Frequency	40 MHz; enables ≤25 ns per bit transfer, achieving ~4 MB/s effective throughput
Write Endurance	10¹⁴ cycles; supports continuous logging for >30 years at 10k writes/sec without wear-out
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 2.5 V and 3.3 V logic domains without level shifting
Operating Temperature	–40°C to +85°C; qualified for industrial control, metering, and automotive body electronics

Pinout & Package

FM25V10-GTR is available in RoHS-compliant 8-pin SOIC (3.9 mm × 4.9 mm) and 8-pin DFN (5 mm × 6 mm) packages. Both variants 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; initiates all opcodes on falling edge
SCK	Serial clock input	Synchronizes all SI/SO transfers; rising edge latches input, falling edge drives output
SI	Serial input	Receives opcodes, addresses, and write data; must be driven to valid logic level at all times
SO	Serial output	Drives read data and status bits; high-impedance 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; requires SCK LOW during transition
VDD	Power supply	2.0–3.6 V core supply; decoupling capacitor required per layout guidelines
VSS	Ground	Reference return path; separate analog/digital grounding not required

Key Features

Feature	Design Value
NoDelay™ write architecture	Eliminates write latency and polling loops-next SPI transaction begins immediately after byte transfer
Ferroelectric memory process	Enables 100 trillion write cycles and 151-year data retention without charge-pump circuitry or wear leveling
Dual write protection scheme	Combines hardware (WP pin) and software (WRSR-controlled block locks) for robust firmware update safety
Device ID and serial number	Read-only Manufacturer ID (0x01), Product ID (0x20), and (on FM25VN10) unique 64-bit serial for board traceability
Low-power operation	5 µA sleep current enables battery-backed operation in energy-constrained IoT endpoints

Use Value: No-delay writes capture final 500 ms of signal without DMA or cache buffering; 2.0 V min VDD supports operation during battery fallback.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MB85RS1MT-FPN-GE1	1 Mbit FRAM, 40 MHz SPI, but only 10¹² endurance and no unique serial number	Lacks device ID readout and serial number; limited to basic logging where traceability is not required	Select when cost sensitivity outweighs need for 100× higher endurance or board-level serialization
AT25SF041-MAHD-T	4 Mbit serial flash, 104 MHz QSPI, but requires erase cycles, 100k write endurance, and polling	Requires software erase management and timeout handling; unsuitable for sub-millisecond write-critical paths	Choose only when density >1 Mbit is mandatory and write frequency is low (<100 writes/hour)

Compared with MB85RS1MT-FPN-GE1, FM25V10-GTR delivers 100× greater endurance and integrated serialization; versus AT25SF041-MAHD-T, it eliminates erase latency and extends lifetime by 10⁹× in high-write environments-making it optimal for deterministic real-time logging.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability nonvolatile memory and programmable system-on-chip solutions for industrial, automotive, and IoT applications.

FAQ

Is FM25V10-GTR pin-compatible with standard SPI EEPROMs like AT25DF041?

Yes-FM25V10-GTR uses identical 8-pin SOIC/DFN footprints and SPI command set (including WREN, WRDI, RDSR, WRSR), enabling direct hardware replacement without PCB redesign. All timing parameters meet or exceed JEDEC-standard serial EEPROM requirements, and mode 0/3 compatibility ensures drop-in use with legacy drivers.

Does FM25V10-GTR require external high-voltage programming or special write sequences?

No-FM25V10-GTR performs writes at bus speed using standard SPI transactions. Unlike flash or EEPROM, it needs no pre-erase cycles, no high-voltage pulses, and no status polling. A write completes within one SPI frame (8 clocks per byte), and the next instruction may begin immediately after CS deassertion.

Can the HOLD pin be left unconnected in a simple microcontroller design?

No-HOLD has a weak internal pull-up but must be tied to VDD if unused. Leaving it floating risks unintended suspension of memory operations due to noise coupling, especially in electrically noisy industrial environments. Cypress explicitly recommends hard-wiring HOLD to VDD unless actively used for multi-task arbitration.

What is the functional difference between FM25V10-GTR and FM25VN10-GTR?

FM25VN10-GTR adds a factory-programmed 64-bit unique serial number accessible via dedicated opcode (0x4B), while FM25V10-GTR omits this feature. Both share identical memory density, timing, endurance, and pinout. The 'N' suffix denotes serialization capability-required for traceability in regulated medical or aerospace deployments.
