Overview

Description

The FM25V20A-DG is a 2-Mbit (256K x 8) non-volatile memory chip from the Ferroelectric RAM (FRAM) family, designed for applications requiring high-speed data storage with low power consumption. Unlike traditional flash memory, FRAM offers fast write speeds, unlimited write cycles, and low operating voltages, making it ideal for applications such as data logging, metering, and industrial automation.
Key features include a serial peripheral interface (SPI) for easy integration with microcontrollers, a wide operating temperature range, and robust data retention capabilities. The FM25V20A-DG is particularly advantageous in scenarios where frequent writes are necessary, as it can withstand millions of write cycles without degradation.
This memory chip is often used in consumer electronics, medical devices, and automotive applications due to its reliability and performance. Its compact size and efficient operation make it a suitable choice for embedded systems and portable devices.

Features

The FM25V20A-DG is a 2 megabit (256K x 8) Serial Flash memory device. Key features include:
1. Interface: SPI (Serial Peripheral Interface) with support for both standard and dual I/O modes.
2. Voltage Range: Operates between 2.7V and 3.6V, making it suitable for a variety of applications.
3. Read Speed: Fast read speeds up to 40 MHz, allowing for efficient data retrieval.
4. Write/Erase: Supports page programming and sector erase, with a typical write time of 2.5 ms per page.
5. Endurance: Capable of withstanding 100,000 program/erase cycles, ensuring reliability over time.
6. Data Retention: Offers data retention of up to 100 years at 85°C.
7. Package: Available in an 8-pin SOIC or other compact packages, suitable for space-constrained designs.
These features make the FM25V20A-DG ideal for applications in consumer electronics, automotive, and industrial systems requiring non-volatile memory solutions.

Package

The FM25V20A-DG is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) format.

Pinout

The FM25V20A-DG is a serial NOR flash memory device with a total of 8 pins. Here are the pin functions:
1. VCC: Power supply (typically 2.7V to 3.6V).
2. GND: Ground reference.
3. SCK: Serial clock input used to synchronize data transmission.
4. SI: Serial input for sending data to the device.
5. SO: Serial output for data read from the device.
6. CS: Chip select, used to activate the device for communication.
