Applications

1. Industrial Automation andamp; Control Systems

Examples: PLCs (Programmable Logic Controllers), smart sensors, motor drives, industrial robots.

Why itand#39;s suitable: These systems need to continuously and rapidly log operational parameters, event logs, fault data, or production counts. The F-RAMand#39;s ultra-high endurance and fast, delay-free writes ensure critical data is saved completely even at the moment of power loss, preventing data loss due to write delays.

2. Automotive Electronics

Examples: Event Data Recorders (EDR) in ADAS, automotive black boxes, instrument clusters, body control modules.

Why itand#39;s suitable: Requires instant logging of large amounts of sensor data during an accident or sudden power loss. F-RAMand#39;s fast write characteristic is ideal. Its high endurance is also suitable for frequently updated data like mileage or door open/close counts.

3. Medical Equipment

Examples: Portable medical monitors (e.g., glucose meters, heart rate monitors), implantable devices, diagnostic equipment.

Why itand#39;s suitable: Devices need to reliably record patient data, usage logs, and calibration information. F-RAMand#39;s low power consumption and high reliability are crucial for data security and long-term stable operation.

4. Smart Metering andamp; Measurement Systems

Examples: Smart electricity meters, water meters, gas meters.

Why itand#39;s suitable: Requires updating cumulative usage data every few seconds and saving the final value instantly before power loss. Daily frequent writes are a significant challenge for EEPROM but are not an issue for F-RAM.

5. Data Loggers

Examples: Environmental monitoring (temperature, humidity, pressure loggers), GPS trackers.

Why itand#39;s suitable: These applications require continuous logging of data streams at high frequencies. F-RAMand#39;s high write speed and infinite endurance allow seamless data logging without the risk of data loss or bottlenecks caused by write delays inherent in EEPROM.

6. High-End Consumer Electronics

Examples: Professional audio equipment, smart home hubs, gaming peripherals.

Why itand#39;s suitable: When fast saving of user settings, game state, or real-time sensor data is needed, F-RAM provides a smoother and more reliable experience than EEPROM.

Description

The FM25CL64B is a 64-Kbit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories.

Unlike serial flash and EEPROM, the FM25CL64B performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte is successfully transferred to the device. The next bus cycle can commence without the need for data polling. In addition, the product offers substantial write endurance compared with other nonvolatile memories. The FM25CL64B is capable of supporting 1014 read/write cycles, or 100 million times more write cycles than EEPROM.

These capabilities make the FM25CL64B ideal for nonvolatile memory applications requiring frequent or rapid writes. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls where the long write time of serial flash or EEPROM can cause data loss.

The FM25CL64B provides substantial benefits to users of serial EEPROM or flash as a hardware drop-in replacement. The FM25CL64B uses the high-speed SPI bus, which enhances the high-speed write capability of F-RAM technology. The device specifications are guaranteed over an industrial temperature range of andndash;40 C to +85 C.
