FM25V20-PG

Memory IC Overview

The FM25V20-PG is a 2-Mbit (256 K × 8) serial ferroelectric random access memory (F-RAM) manufactured by Infineon Technologies. It utilizes an industry-standard SPI interface with clock frequencies up to 40 MHz and supports SPI modes 0 and 3. The device operates within a voltage range of 2.0 V to 3.6 V and functions across an industrial temperature range of –40 °C to +85 °C. It is housed in an 8-pin small outline integrated circuit (SOIC) package.

Memory IC Feature Summary

• Provides high-endurance performance capable of supporting 10^14 read/write cycles.
• Features NoDelay writes that operate at bus speed without requiring data polling.
• Includes sophisticated write protection schemes utilizing hardware WP pins and software block protection.
• Offers low power consumption with active, standby, and sleep mode current specifications.

Memory IC Applications

• Data collection systems requiring frequent or rapid write cycles
• Industrial controls where long write times of other nonvolatile memories cause data loss
• Hardware drop-in replacements for serial flash and EEPROM

Memory IC Procurement Notes

Verify the specific ordering suffix 'PG' corresponds to the 8-pin SOIC package variant as documented in the official datasheet. Confirm that the component status aligns with the provided documentation indicating this specification is obsolete. Ensure compatibility with existing PCB footprints designed for the SOIC-8 form factor before procurement.

Memory IC Selection Notes

Select this component when applications demand extreme write endurance and zero-write-delay performance compared to traditional nonvolatile memories. It is suitable for designs requiring direct hardware replacement for serial flash or EEPROM while maintaining SPI compatibility. Consider the industrial temperature range and low-voltage operation requirements for system integration.
