Product details

Overview

FM25V10-PG 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 2.0–3.6 V over –40 °C to +85 °C and supports 40-MHz SPI modes 0 and 3. Used in industrial data loggers for real-time parameter storage where EEPROM write latency causes data loss.

For engineers reviewing the FM25V10-PG datasheet, FM25V10-PG pinout, FM25V10-PG application, or FM25V10-PG equivalent, key selection criteria include write-cycle endurance, zero-write-delay timing behavior, SPI bus compatibility with legacy EEPROM/flash firmware, and hardware write protection via WP pin.

Technical Context

The FM25V10-PG implements a synchronous SPI slave interface with dual-mode support (Mode 0 and Mode 3), latching inputs on SCK rising edge and driving outputs on falling edge. Its internal F-RAM array eliminates erase-before-write overhead, enabling immediate byte-level writes without polling.

It integrates a nonvolatile status register with configurable block protection (1/4, 1/2, or full array), hardware write protection via active-low WP pin, and device identification (Manufacturer ID + Product ID). The HOLD pin suspends ongoing transfers synchronously when SCK is low, preserving bus state during host interrupts.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	1 Mbit (128K × 8); supports byte- and page-write without erase cycles
Write Endurance	10¹⁴ cycles; enables >100 years of daily 1000-write logging at 1 Hz
Data Retention	151 years at 85 °C; no refresh required across industrial temperature range
SPI Speed	Up to 40 MHz; matches high-speed microcontroller SPI peripherals without timing margin loss
Supply Voltage	2.0 V to 3.6 V; compatible with 3.3 V I/O domains and brown-out tolerant operation
Active Current	300 µA at 1 MHz; reduces system power budget in battery-backed data capture
Standby Current	90 µA typical; enables low-power sleep between sensor sampling intervals

Pinout & Package

FM25V10-PG is supplied in an 8-pin SOIC package (PG suffix), with lead-free, RoHS-compliant construction and standard JEDEC MS-012AC footprint.

Pin/Terminal	Circuit Role	Design Meaning
CS	Chip Select input	Active-low enable; places device in standby and tristates SO when HIGH
SCK	Serial clock input	Synchronizes all SPI transfers; rising edge latches SI, falling edge drives SO
SI	Serial input	Receives opcodes, addresses, and write data; must be driven to valid logic level
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; tie to VDD if unused
HOLD	Bus hold control	Suspends ongoing SPI transfer synchronously; transitions only allowed when SCK = LOW
VDD	Power supply	2.0–3.6 V core and I/O supply; decoupling capacitor required near pin
VSS	Ground	System reference ground; must be low-impedance connection to minimize noise

Key Features

Feature	Design Value
NoDelay™ write architecture	Eliminates write polling and timeout handling in firmware; next SPI transaction starts immediately after byte transfer
Ferroelectric memory cell	Enables 10¹⁴ write cycles - 100 million × more than standard EEPROM - with no wear leveling required
Dual SPI mode support	Interoperates with both Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) masters without configuration change
Hardware/software write protection	Combines WP pin lock with software-configurable block protection (1/4, 1/2, or full array) for robust data integrity
Device ID and status register	Allows host to verify manufacturer, density, revision, and current protection state via standardized SPI commands

Applications

Industrial Data Logging

Smart Metering

Use Scenario: Continuous timestamped recording of sensor readings (e.g., temperature, pressure) in factory automation PLCs.

IC Role / Device Role / Timing Role: Nonvolatile scratchpad memory storing last-known state and incremental logs between power cycles.

Use Value: Eliminates risk of lost samples during power interruption due to zero-write-delay and no erase latency.

Use Scenario: Storing tariff schedules, consumption history, and tamper-event timestamps in electricity/water meters.

IC Role / Device Role / Timing Role: High-endurance parameter store updated hourly/daily under constrained power budgets.

Use Value: Supports >100 years of daily writes without degradation, exceeding meter lifetime requirements.

Medical Diagnostic Devices

Automotive Telematics

Use Scenario: Capturing real-time ECG waveform segments and fault codes during portable diagnostic sessions.

IC Role / Device Role / Timing Role: Buffer memory retaining critical diagnostics even during unexpected shutdowns.

Use Value: Guarantees data persistence without backup capacitors or complex power-fail interrupt schemes.

Use Scenario: Recording vehicle OBD-II event codes, GPS coordinates, and crash-triggered snapshots in black-box modules.

IC Role / Device Role / Timing Role: Crash-robust nonvolatile storage synchronized to CAN bus triggers.

Use Value: Writes complete within single SPI frame (<250 ns at 40 MHz), ensuring capture before power collapse.

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 requires external V_DD decoupling per JEDEC spec; no HOLD pin	Lacks suspend-on-HOLD capability; unsuitable for hosts requiring mid-transfer bus arbitration	Select when HOLD functionality is unused and board layout allows tighter decoupling
AT25DF041A-SSH-T	4-Mbit serial flash, 85-MHz DTR mode, but 20-ms page-program time and 100k-cycle endurance	Requires firmware polling and wear leveling; incompatible with zero-latency write protocols	Select only when density >1 Mbit is mandatory and write frequency is <100×/day

Compared with MB85RS1MT-FPN-GE1 and AT25DF041A-SSH-T, FM25V10-PG uniquely delivers guaranteed sub-microsecond write commit, 10¹⁴-cycle endurance, and synchronous HOLD suspension - making it the only choice for deterministic, high-frequency, mission-critical logging.

FAQ

Is FM25V10-PG pin-compatible with standard SPI EEPROMs like AT25XXX?

Yes - FM25V10-PG uses identical 8-pin SOIC pinout and SPI command set (WREN, WRDI, RDSR, WRSR, READ, WRITE) as industry-standard serial EEPROMs. Firmware migration requires only recompilation; no PCB or schematic changes are needed.

Does FM25V10-PG require special PCB layout considerations compared to flash memory?

No special high-speed routing is needed, but a 0.1 µF ceramic decoupling capacitor must be placed within 5 mm of VDD/VSS pins. Unlike flash, no large bulk capacitance is required since write current is continuous and low (300 µA active), not pulsed.

Can the HOLD pin be left unconnected?

No - HOLD has a weak internal pull-up, but Cypress specifies tying it to VDD if unused to prevent unintended bus suspension from noise coupling. Leaving it floating risks spurious hold activation during ESD events or signal crosstalk.

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

FM25VN10-PG adds a factory-programmed unique 64-bit serial number and extended device ID register. FM25V10-PG lacks this feature but shares identical memory array, timing, endurance, and pinout - making it suitable for cost-sensitive applications where board-level serialization is unnecessary.
