Data Sheet - FM25V20A-DG

Infineon FRAM, 2MB Memory Size, SPI Interface - FM25V20A-DG

This fram is a serial non-volatile memory device intended for high-reliability storage in embedded systems. It operates within common automotive and industrial temperature ranges and communicates via a serial peripheral interface, making it suitable for designs that require frequent writes and fast access without specialised EEPROM management.

Features and Benefits:

• 16ns maximum random access time enables rapid data retrieval
• 40MHz maximum clock frequency supports high-speed SPI transfers
• 2MB memory capacity provides extensive on-board storage
• 8-bit data bus width simplifies byte-oriented integration
• AEC-Q100 automotive standard suitability aids vehicle electronics use
• Operates from 2V to 3.6V supplying low-voltage systems compatibility

Applications

• Suitable for automotive data-logging modules in vehicles
• Ideal for industrial control units requiring frequent writes
• Used with microcontrollers needing non-volatile scratchpad memory
• Can be used for sensor calibration storage in harsh environments
• Appropriate for power-loss-safe transaction recording systems

How many addressable words does it offer for software mapping?

The device organisation provides 256K words of 8 bits each, allowing straightforward byte-aligned addressing across the full memory space.

What physical package should designers anticipate when laying out PCBs?

It is supplied in a DFN surface-mount package with an 8-pin configuration and a low-profile height suited to compact board designs.

What environmental limits must be considered for deployment?

The permitted ambient range spans from -40°C up to 85°C, accommodating many automotive and industrial applications.

Which supply constraints must be observed to ensure correct operation?

Ensure the supply rail stays between 2V minimum and 3.6V maximum to maintain device functionality and data integrity.
