The FM22L16 is a 16kb parallel F-RAM (Ferroelectric Random Access Memory) device manufactured by Ramtron. F-RAM offers a unique combination of RAM-like speed with non-volatile data storage. It retains data even when power is removed, similar to flash memory, but with significantly faster write speeds and higher endurance.

Applications

• Data logging
• Metering
• Industrial controls
• Medical devices
• Gaming applications

Features

• 16kb (2K x 8) non-volatile memory
• Parallel interface
• Fast write speeds (virtually no write delay)
• Unlimited read/write cycles (high endurance)
• Low power consumption
• RoHS compliant

Benefits

• Instant write data retention
• Eliminates the need for battery backup in many applications
• Simplified system design
• Improved system reliability
• Lower power consumption compared to EEPROM or flash memory

Technical Specifications

Based on available datasheets and typical F-RAM characteristics, the FM22L16 likely features the following specifications:

• Memory Size: 16kb (2048 x 8 bits)
• Interface: Parallel
