Product details

Overview

FM25V20-GTR from Infineon Technologies (formerly Cypress) is a 2-Mbit serial SPI F-RAM memory organized as 256 K × 8, operating at up to 40 MHz with 2.0–3.6 V supply, 10¹⁴ write endurance, and 151-year data retention. It serves as a hardware-compatible nonvolatile memory replacement for serial flash/EEPROM in real-time data logging and industrial control systems where rapid, delay-free writes are critical.

For engineers reviewing the FM25V20-GTR datasheet, FM25V20-GTR pinout, FM25V20-GTR application, or FM25V20-GTR equivalent, key selection criteria include NoDelay™ write performance, SPI Mode 0/3 compatibility, hardware/software write protection, industrial temperature range (–40 °C to +85 °C), and dual-package availability (SOIC-8/TDFN-8).

Technical Context

The FM25V20-GTR implements ferroelectric memory technology enabling true RAM-like random access with nonvolatile data retention. Its SPI interface supports full-duplex communication at up to 40 MHz, with inputs latched on SCK rising edge and outputs driven on falling edge in both Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1).

Internal architecture includes an 18-bit address counter, nonvolatile status register with WPEN bit, device ID register (Manufacturer ID 0x01, Product ID 0x20), and dedicated HOLD/CS-controlled transaction suspension. Write operations complete within one SPI byte transfer cycle-no polling or erase cycles required.

Key Specifications

Interface Speed	Up to 40 MHz SPI clock - enables ~5 MB/s sequential write throughput
Write Endurance	10¹⁴ read/write cycles - supports >27,000 writes/sec continuously for 10+ years
Data Retention	151 years at +85 °C - guaranteed nonvolatile storage without refresh or backup power

Operating Temp	–40 °C to +85 °C - qualified for industrial control, metering, and automotive body electronics
Active Current	300 µA at 1 MHz - enables low-power sensor node memory buffering

Pinout & Package

FM25V20-GTR is available in two RoHS-compliant packages: 8-pin SOIC (3.9 mm × 4.9 mm) and 8-pin TDFN (3 mm × 2 mm) with exposed pad (unconnected). Both packages share identical pin functions and ordering code suffix "-GTR" denotes tape-and-reel packaging.

Pin/Terminal	Circuit Role	Design Meaning
CS	Chip Select input	Active-low enable; places device in standby (100 µA) when HIGH; must fall before each opcode
SCK	Serial clock input	Synchronizes all I/O; rising edge latches SI, falling edge drives SO; supports 0–40 MHz
SI	Serial input	Receives opcodes, addresses, and write data; sampled on SCK rising edge
SO	Serial output	Drives read data and status bits on SCK falling edge; high-impedance when CS HIGH or HOLD LOW
WP	Write protect input	Hardware lock for status register when WPEN=1; must be tied to VDD if unused
HOLD	Operation suspend input	Pauses ongoing read/write when pulled LOW while SCK is LOW; resumes on next CS fall
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 internal circuitry and I/O; separate analog/digital ground not required

Key Features

Feature	Design Value
NoDelay™ Writes	Byte-level writes complete within one SPI clock cycle - eliminates timeout polling and firmware overhead
Ferroelectric Memory Core	10¹⁴ write cycles and 151-year retention without wear leveling or ECC management
Dual SPI Mode Support	Native compatibility with Mode 0 and Mode 3 - interoperable with STM32, PIC, MSP430, and NXP Kinetis MCUs
Multi-Layer Write Protection	Hardware (WP pin), software (WREN/WRDI), and block-level (1/4, 1/2, full array) locking
Device Identification	Read-only Manufacturer ID (0x01) and Product ID (0x20) - enables automatic BOM validation and firmware detection

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY14B102QN-SP	Same F-RAM core, but 2.7–3.6 V only; no 2.0 V support; TQFP-44 package	Requires higher VDD; unsuitable for 2.5 V systems or space-constrained layouts	Select only if existing design uses TQFP footprint and operates ≥2.7 V
AT25SF041-SSHD-B	4 Mbit SPI flash; requires 25 ms page program time; 100k write cycles; no NoDelay™	Needs firmware polling and wear leveling; incompatible with burst-write timing constraints	Acceptable only for infrequent configuration storage where write latency <100 ms is tolerable

Compared with CY14B102QN-SP and AT25SF041-SSHD-B, FM25V20-GTR uniquely delivers 2.0 V operation, 10¹⁴ endurance, and zero-latency writes in compact SOIC/TDFN packages - making it the sole choice for high-frequency data capture in power-sensitive industrial and medical systems.

FAQ

Is FM25V20-GTR pin-compatible with standard SPI EEPROMs like AT25DF041?

Yes - FM25V20-GTR uses identical SOIC-8 and TDFN-8 footprints and SPI command set (WREN, WRDI, RDSR, WRSR, READ, WRITE) as legacy serial EEPROMs. No PCB redesign is needed; only firmware timing adjustments are eliminated due to NoDelay™ writes.

Does FM25V20-GTR require external high-voltage programming or erase pulses?

No - FM25V20-GTR performs all write and erase operations using only the standard 2.0–3.6 V VDD supply. There is no need for charge pumps, external VPP pins, or sector-erase commands. Each byte writes independently at bus speed.

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

When HOLD is pulled LOW while SCK is LOW, the FM25V20-GTR immediately suspends the current write or read transaction. The internal address counter and status remain preserved. Operation resumes on the next falling edge of CS, continuing from the exact suspended byte position.

Can FM25V20-GTR be used in SPI multi-drop configurations with other slaves?

Yes - FM25V20-GTR operates as a standard SPI slave with dedicated CS input. Multiple FM25V20-GTR devices can share the same SCK, SI, and SO lines when each has its own CS signal routed from the master MCU GPIO.
