Product details
Overview
FM25V10-DGTR from Cypress Semiconductor is a 1-Mbit (128K × 8) serial SPI ferroelectric RAM (F-RAM) with NoDelay™ write capability, 40-MHz max SPI clock, and 1014 read/write endurance. It operates from 2.0 V to 3.6 V across –40 °C to +85 °C and replaces serial EEPROM/flash in data-logging, industrial control, and metering systems where rapid nonvolatile writes are critical.
For engineers reviewing the FM25V10-DGTR datasheet, FM25V10-DGTR pinout, FM25V10-DGTR application, or FM25V10-DGTR equivalent, key selection criteria include guaranteed bus-speed writes without polling, hardware/software write protection, unique serial number support (FM25VN10 variant), industrial temperature rating, and RoHS-compliant 8-pin SOIC packaging.
Technical Context
The FM25V10-DGTR implements a synchronous SPI slave interface supporting modes 0 (CPOL = 0, CPHA = 0) and 3 (CPOL = 1, CPHA = 1), with data latched on SCK rising edge and output on falling edge. Its internal F-RAM array eliminates erase cycles and write latency inherent in flash/EEPROM.
Write operations complete within one SPI byte transfer cycle - no status polling required - enabled by ferroelectric cell architecture and integrated write-enable latch control. The device integrates a 3-bit nonvolatile status register for block protection (1/4, 1/2, or full array), WP pin hardware lock, and HOLD pin for transaction suspension.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8); supports byte-level random access without page/sector erase overhead |
| SPI Clock Frequency | Up to 40 MHz; enables ≤25 ns per bit transfer, matching microcontroller bus speed |
| Write Endurance | 1014 cycles; supports >27,000 writes/sec continuously for 151 years at 25 °C |
| Data Retention | 151 years at 25 °C; guaranteed over full industrial temperature range without refresh |
| Supply Voltage | 2.0 V to 3.6 V; compatible with 2.5 V and 3.3 V logic domains without level shifting |
| Active Current | 300 µA at 1 MHz; enables low-power data capture in battery-backed systems |
| Standby Current | 90 µA typical; reduces quiescent power during host idle periods |
Pinout & Package
FM25V10-DGTR is supplied in an 8-pin small outline integrated circuit (SOIC) package with gull-wing leads, JEDEC MS-012AC compliant, body size 5.3 mm × 6.2 mm × 1.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby and tristates SO when HIGH; initiates all commands on falling edge |
| SCK | Serial clock input | Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–40 MHz with interruptible clock |
| SI | Serial input | Receives opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |
| 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 state; transitions only allowed while SCK is LOW |
| VDD | Power supply | 2.0–3.6 V core and I/O supply; decoupling capacitor required per datasheet layout guidelines |
| VSS | Ground | Reference return path for all signals and power; must connect to system ground plane |
Key Features
| Feature | Design Value |
|---|---|

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-FPNSE1 | 1-Mbit FRAM, 40-MHz SPI, but requires 1.8–3.6 V supply and lacks unique serial number | Valid for low-voltage systems (<2.0 V), but not suitable where traceability or 2.0 V minimum operation is required | Select when operating below 2.0 V or when serial number is unnecessary |
| AT25DF041A-SHN-T | 4-Mbit serial flash with 80-MHz DTR mode, but requires erase-before-write and has only 100K endurance | Applicable for code storage or infrequent config updates, not for high-frequency data logging | Select only for read-mostly applications where write frequency is <100x/day |
Compared with MB85RS1MT-FPNSE1 and AT25DF041A-SHN-T, FM25V10-DGTR uniquely delivers guaranteed 2.0 V operation, 1014 endurance, and built-in serial number - making it the sole choice for mission-critical, high-write industrial and medical data buffers requiring long-term reliability without voltage margin compromise.

FAQ
Is FM25V10-DGTR pin-compatible with standard 8-pin SOIC SPI flash or EEPROM devices?
Yes - FM25V10-DGTR uses identical 8-pin SOIC footprint and SPI signal mapping (CS, SCK, SI, SO, WP, HOLD, VDD, VSS) as industry-standard serial flash and EEPROM. Pin functions match JEDEC-standard SPI memory pinouts, enabling direct PCB-level replacement without layout changes.
Does FM25V10-DGTR require special initialization or firmware drivers beyond standard SPI?
No - FM25V10-DGTR uses standard SPI opcodes (0x02 for write, 0x03 for read, 0x05 for status read) and requires no erase commands or status polling. Existing SPI flash/EEPROM drivers can be reused with minor modifications to remove wait loops and adjust timing parameters.
What is the functional difference between FM25V10-DGTR and FM25VN10-DGTR?
FM25VN10-DGTR is a factory-programmed variant of FM25V10-DGTR that includes a unique, read-only 64-bit serial number stored in dedicated ROM. Both share identical memory density, timing, and electrical specs; only FM25VN10 provides board-level traceability via its unalterable serial ID.
Can FM25V10-DGTR operate reliably at 2.0 V while sustaining 40-MHz SPI communication?
Yes - FM25V10-DGTR is fully specified for 40-MHz operation down to 2.0 V, as confirmed in AC switching characteristics (Table 17, Rev. *K datasheet). At 2.0 V, tCLK min remains 25 ns, supporting full-speed transfers without derating or timing margin loss.
