Memory IC datasheet and documents for FM25VN05-G
Memory IC Overview
The FM25VN05-G is a 512-kbit (64K x 8) Ferroelectric Random Access Memory (F-RAM) manufactured by Infineon Technologies, formerly Ramtron. It utilizes a Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 2.0 V to 3.6 V. The device supports clock frequencies up to 40 MHz and is housed in an 8-pin SOIC package. It features nonvolatile data retention without write delays and includes hardware and software write protection schemes.
Memory IC Feature Summary
- Nonvolatile ferroelectric memory technology enabling instantaneous writes without erase cycles
- Serial Peripheral Interface (SPI) compatibility with standard modes 0 and 3
- Integrated unique serial number for individual device identification
- Dual-layer write protection via hardware pins and software commands
Memory IC Applications
- Data logging systems requiring high endurance and fast write speeds
- Industrial control units needing reliable nonvolatile storage
- Smart metering applications with frequent parameter updates
- Automotive electronics demanding robust data retention
Memory IC Procurement Notes
Verify the manufacturer designation as Infineon Technologies, reflecting the acquisition of Ramtron. Confirm the specific suffix 'G' indicates lead-free and RoHS compliance. Ensure the SPI interface timing parameters match the target system's maximum clock frequency requirements before integration.
Memory IC Selection Notes
Select this component when high-cycle endurance and byte-level write granularity are required. It serves as a direct hardware replacement for serial flash memory in many designs. Consider the 64K x 8 organization and 40 MHz SPI speed for performance matching against alternative FRAM or EEPROM solutions.
Memory IC Part Context
This part belongs to the FM25V series of serial F-RAM devices. It shares architectural similarities with the FM25V05-G but adds a unique serial number feature. The series is characterized by low power consumption and industrial temperature range operation, positioning it between standard FRAM and specialized secure memory variants.
Memory IC Replacement Considerations
The FM25V05-G is a functional substitute lacking the unique serial number feature. Verify pinout compatibility and SPI command set alignment when substituting with other serial FRAM devices from the same family.
