FM28V020-SGTR FRAM (Ferroelectric RAM) Memory IC 256Kbit Parallel 140 ns 28-SOIC
The FM28V020-SGTR is a high-performance 2-Mbit (256K × 8) non-volatile Ferroelectric RAM (FRAM) that combines the speed of SRAM with the data retention of flash memory. Operating at 3.3V, this memory chip offers virtually unlimited read/write endurance (10^14 cycles) and 10-year data retention, making it ideal for applications requiring frequent data updates and high reliability. With a fast 70ns access time and low power consumption, the FM28V020-SGTR is well-suited for industrial automation, metering, automotive systems, and IoT devices where fast writes and non-volatility are critical.
The FRAM device features a standard parallel interface, ensuring easy integration with microcontrollers and legacy systems. Unlike traditional EEPROM or flash memory, FRAM technology enables byte-level read/write operations without erase cycles, significantly improving system performance. The FM28V020-SGTR also supports industrial temperature ranges (-40°C to +85°C), ensuring stable operation in harsh environments. Its high noise immunity and radiation-resistant properties make it a preferred choice for aerospace, medical, and automotive applications where data integrity is paramount.
Key applications include data logging, power meters, industrial control systems, and automotive black boxes, where fast and reliable non-volatile memory is essential. The FM28V020-SGTR is available in a 44-pin TSOP-II package, providing a compact footprint for space-constrained designs. Additionally, its low standby current and fast write speeds make it an excellent alternative to battery-backed SRAM, eliminating the need for external power backup solutions.
Alternative FRAM memory Models:
● FM18W08-SG: 1-Mbit (128K × 8) FRAM, lower density but same endurance and speed.
● CY15B104Q-SXE: 4-Mbit (512K × 8) FRAM, higher capacity with SPI interface.
● MR25H40CDF: 4-Mbit (512K × 8) MRAM, alternative non-volatile memory with similar performance.
● AT24C1024B: 1-Mbit EEPROM, lower endurance but cost-effective for less demanding applications.
