Product details

Overview

FM25VN10-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 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 sensor storage where EEPROM latency causes data loss.

For engineers reviewing the FM25VN10-G datasheet, FM25VN10-G pinout, FM25VN10-G application, or FM25VN10-G equivalent, key selection criteria include write-cycle speed without polling, guaranteed 10¹⁴ endurance, unique serial number support, and hardware/software write protection for mission-critical nonvolatile storage.

Technical Context

The FM25VN10-G implements a synchronous SPI slave interface with dual-mode compatibility (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 true byte-level random access at bus speed.

Write protection is implemented via three independent mechanisms: hardware WP pin control, software WREN/WRDI instructions, and configurable block protection (1/4, 1/2, or full array) through the nonvolatile status register. Device identification includes fixed Manufacturer ID (0x01), Product ID (0x20), and a factory-programmed unique 64-bit serial number.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	1 Mbit (128K × 8); enables direct replacement of 1-Mbit serial flash/EEPROM without address remapping
Write endurance	10¹⁴ cycles; supports >27,000 writes/sec continuously for 10+ years in high-frequency logging
Data retention	151 years at +85 °C; eliminates periodic refresh or backup power requirements
SPI speed	Up to 40 MHz; achieves ~4 MB/s effective write throughput with zero wait states
Supply voltage	2.0 V to 3.6 V; interoperable with 3.3 V and 2.5 V logic domains without level shifters
Operating temperature	–40 °C to +85 °C; qualified for industrial control cabinets and outdoor metering enclosures
Active current	300 µA at 1 MHz; reduces average power in battery-backed data acquisition nodes

Pinout & Package

FM25VN10-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 (not connected).

Pin/Terminal	Circuit Role	Design Meaning
CS	Chip Select input	Active-low enable; places device in standby (90 µA) when HIGH; required falling edge precedes every opcode
SCK	Serial clock input	Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–40 MHz with arbitrary pauses
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; tristated during HOLD or when CS is HIGH
WP	Write protect input	Hardware lock for status register; must be tied to VDD if unused; overrides software protection when asserted
HOLD	Operation suspend input	Pauses ongoing transfer without losing state; transitions only allowed while SCK is LOW
VDD	Power supply	2.0–3.6 V core supply; decoupling capacitor required within 10 mm of pin
VSS	Ground	Reference return path; must connect to system ground plane with low-impedance trace

Key Features

Feature	Design Value
NoDelay™ write architecture	Eliminates polling loops and timeout handling in firmware; write completion is implicit after final SCK edge
Unique 64-bit serial number	Factory-programmed, read-only identifier enabling board-level traceability and anti-cloning in field-deployed systems
Dual SPI mode support	Compatible with legacy and modern microcontrollers using either mode 0 (CPOL=0, CPHA=0) or mode 3 (CPOL=1, CPHA=1)
Three-tier write protection	Hardware (WP pin), instruction-based (WREN/WRDI), and granular (1/4–full array) software locking prevent accidental corruption
Low-power sleep mode	5 µA quiescent current enables multi-year operation from coin-cell batteries in remote monitoring nodes

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
MB85RS1MT-FPN-GE1	Fujitsu 1-Mbit SPI F-RAM; identical 40-MHz speed and 10¹⁴ endurance but lacks unique serial number and uses different status register layout	No built-in board ID; requires external tracking for serialization-sensitive deployments	Select when serial number is unnecessary and existing Fujitsu qualification exists
AT25DF041A-SSH-T	Atmel 4-Mbit SPI flash; requires page erase before write, 100k-cycle endurance, 20-year retention, and polling overhead	Higher density but unsuitable for sub-millisecond write-critical logging	Select only for static configuration storage where write frequency < 100/day

Compared with MB85RS1MT-FPN-GE1, FM25VN10-G offers traceability via unique serial number and Cypress's mature F-RAM driver ecosystem; versus AT25DF041A-SSH-T, it delivers 10⁹× higher endurance and eliminates write-latency-induced data gaps in real-time systems.

FAQ

Is FM25VN10-G pin-compatible with standard 8-pin SPI flash or EEPROM devices?

Yes-FM25VN10-G shares identical 8-pin SOIC and DFN footprints and SPI signal mapping (CS, SCK, SI, SO, WP, HOLD, VDD, VSS) with industry-standard serial flash and EEPROM. No PCB redesign is needed for drop-in replacement, though firmware must disable polling and adjust status register handling.

Does the unique serial number require special initialization or command sequence?

No-the 64-bit serial number is factory-programmed and permanently stored in read-only memory. It is accessed using the standard RDID (0x9F) command followed by a 4-byte read sequence (Manufacturer ID, Product ID, then two serial number bytes), requiring no setup or unlock sequence.

How does the HOLD pin behave during an active write operation?

When HOLD is pulled LOW during a write, the FM25VN10-G immediately suspends data transfer without corrupting the current byte. The internal address counter and state machine freeze; resuming with HOLD HIGH restores operation from the exact suspended point-no retransmission or restart is needed.

Can FM25VN10-G operate reliably at 2.0 V while sustaining 40-MHz SPI communication?

Yes-Cypress specifies full 40-MHz operation down to 2.0 V. The device maintains timing compliance (tSU, tH, tV) across the entire 2.0–3.6 V range, verified per AC switching characteristics in Rev. *H datasheet, making it suitable for brownout-prone battery-powered systems.
