Product details

Overview

FM25V01A-GTR from Cypress Semiconductor is a 128-Kbit (16K × 8) serial SPI F-RAM nonvolatile memory 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 in an 8-pin SOIC package and serves as a hardware drop-in replacement for serial EEPROM and flash in high-write-frequency data logging systems.

For engineers reviewing the FM25V01A-GTR datasheet, FM25V01A-GTR pinout, FM25V01A-GTR application, or FM25V01A-GTR equivalent, key selection criteria include SPI mode 0/3 compatibility, write-protection granularity (1/4, 1/2, full array), 40-MHz max clock rate, and ultra-low 8-μA sleep current - all critical for deterministic real-time logging and industrial control firmware.

Technical Context

The FM25V01A-GTR implements a ferroelectric memory array with zero-latency write execution: each byte is committed immediately upon SPI transfer completion, eliminating polling and timeout handling. Its status register supports configurable block protection and WP pin hardware lock, enabling robust field-upgrade and parameter storage integrity.

It uses synchronous SPI slave architecture with dual-mode support (CPOL/CPHA = 0/0 and 1/1), rising-edge input sampling and falling-edge output driving, and a dedicated Device ID register returning manufacturer and product revision codes - essential for multi-vendor BOM validation and firmware auto-detection.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Kbit (16K × 8) - supports 16,384 unique byte-addressable locations for compact firmware parameter tables or sensor history buffers.
Write Endurance	10¹⁴ cycles - enables >27 years of continuous 100-Hz logging without wear-out, unlike EEPROM limited to ~10⁶ cycles.
Data Retention	151 years at +85 °C - guarantees unpowered data integrity across full industrial lifecycle without refresh or backup power.
SPI Speed	Up to 40 MHz - achieves 4 MB/s effective write throughput with no inter-byte delay, matching RAM-like system responsiveness.
Supply Voltage	2.0 V to 3.6 V - interoperates directly with 3.3-V microcontrollers and low-power IoT SoCs without level-shifting.
Operating Temp	–40 °C to +85 °C - qualified for deployment in motor drives, PLC modules, and outdoor metering enclosures.
Standby Current	150 μA - minimizes quiescent power in battery-backed data recorders during idle intervals.

Pinout & Package

FM25V01A-GTR is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package with standard 1.27-mm pitch and gull-wing leads, compatible with automated SMT assembly and IPC-7351B footprint IPC_0805_SOIC_8.

Pin/Terminal	Circuit Role	Design Meaning
SCK	Serial Clock Input	Synchronizes all SPI transfers; sampled on rising edge, supports 0–40 MHz; clock may be paused mid-transaction.
CS	Chip Select Input	Active-low enable; device enters standby and tri-states SO when HIGH; falling edge initiates opcode sequence.
SI	Serial Data Input	Receives opcodes, addresses, and write data; latched on rising SCK edge; must be driven to valid logic level for IDD compliance.
SO	Serial Data Output	Drives read data and status bits on falling SCK edge; high-impedance when CS HIGH or HOLD LOW.
WP	Hardware Write Protect	Active-low lock for Status Register writes when WPEN=1; must be tied to VDD if unused to prevent accidental protection.
HOLD	Bus Hold Control	Pauses ongoing SPI operation when LOW; requires SCK=LOW before transition; enables CPU context switching without bus arbitration.
VSS	Ground Reference	System ground return path; must be low-impedance connection to minimize noise coupling into F-RAM core.
VDD	Power Supply	2.0–3.6 V supply; decoupling capacitor (0.1 μF) required within 5 mm for stable 40-MHz operation.

Key Features

Feature	Design Value
NoDelay™ Writes	Zero-latency byte-level commits eliminate polling loops and reduce firmware complexity in time-critical logging tasks.
10¹⁴ Endurance	Supports >100 million times more writes than EEPROM, enabling reliable high-frequency sensor sampling without wear leveling.
SPI Mode 0/3 Compatibility	Interoperates with legacy and modern microcontrollers (e.g., STM32, PIC, MSP430) without custom driver modifications.
Configurable Block Protection	Software-selectable 1/4, 1/2, or full-array write lock via Status Register - secures calibration data while allowing runtime parameter updates.
Device ID Readback	Manufacturer ID (0x01) and Product ID (0x01) returned on command - enables automatic BOM verification and counterfeit detection in production test.

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	Fujitsu 1-Mbit FRAM; 5-V tolerant; 20-MHz max SPI; no HOLD pin; different status register layout.	Lacks HOLD functionality and 40-MHz speed; suitable only where lower bandwidth and simpler control suffice.	Select when 1-Mbit density is required and system clock <20 MHz; verify WP/HOLD signal mapping in PCB layout.
AT25DF041A-SSH-T	Microchip 4-Mbit serial flash; 85-MHz DTR capable; requires 25-ms erase/write; no inherent endurance guarantee.	Requires erase-before-write and polling; unsuitable for sub-10-ms write intervals or >10⁶ lifetime writes.	Choose only for static firmware storage where infrequent updates and higher density outweigh latency and endurance constraints.

Compared with MB85RS1MT-FPNSE1 and AT25DF041A-SSH-T, FM25V01A-GTR uniquely delivers deterministic 40-MHz write throughput, 10¹⁴ endurance, and HOLD-assisted transaction suspension - making it the sole choice for real-time embedded logging requiring both speed and longevity.

FAQ

Is FM25V01A-GTR pin-compatible with standard SPI EEPROMs like AT25XXX series?

Yes - FM25V01A-GTR uses identical 8-pin SOIC packaging and matches the pinout of common 8-pin SPI EEPROMs (CS, SO, WP, VSS, VDD, SI, SCK, HOLD). Its SPI command set is also backward-compatible with standard read/write opcodes, enabling direct hardware substitution without PCB redesign.

Does FM25V01A-GTR require external high-voltage programming or erase pulses?

No - FM25V01A-GTR performs all writes at standard VDD levels (2.0–3.6 V) with no erase cycle or high-voltage charge pump. Each byte is written synchronously with the SPI clock, eliminating erase timing windows, voltage margining, and associated reliability risks found in flash and EEPROM.

How does the HOLD pin function during an active read or write operation?

When HOLD is pulled LOW during any SPI transaction, the FM25V01A-GTR suspends communication immediately: SCK is ignored, CS remains active, and SO goes high-impedance. The internal address counter and state machine retain position, allowing seamless resumption after HOLD returns HIGH - ideal for interrupt-driven MCU architectures.

What is the significance of the Device ID feature in FM25V01A-GTR?

The Device ID (Manufacturer ID = 0x01, Product ID = 0x01) allows host firmware to verify authentic Cypress silicon at boot time, detect counterfeit parts, and auto-configure drivers for density and protection features - critical for secure field updates and regulatory compliance in medical and industrial deployments.
