FM24CL64B / FM24CL16-G / FM6316FE SOP-8 I²C / SPI FRAM Memory IC – Pack of 5

FM24CL64B / FM24CL16-G / FM6316FE SOP-8 FRAM Memory IC – Pack of 5

FRAM (Ferroelectric RAM) is a non-volatile memory technology that combines the best properties of SRAM and EEPROM: it writes at SRAM speed (no write delay), has virtually unlimited write endurance (100 trillion cycles vs 1 million for EEPROM), and retains data without power like EEPROM. The FM24CL64B, FM24CL16-G, and FM6316FE from Cypress Semiconductor (now Infineon) are the most widely used FRAM ICs in embedded systems requiring frequent non-volatile writes – data logging, odometers, event counters, and real-time parameter storage. This 5-piece SOP-8 pack is ideal for engineers who need reliable, high-endurance non-volatile storage.

FRAM vs EEPROM – Why FRAM Wins for Frequent Writes

• EEPROM write endurance: 1,000,000 cycles – exhausted in 11 days at 1 write/ms
• FRAM write endurance: 100,000,000,000,000 cycles – effectively unlimited
• EEPROM write time: 5ms per byte (blocking)
• FRAM write time: No delay – write completes at bus speed
• Use FRAM for: odometers, event counters, real-time data logging, power-fail safe storage
• Use EEPROM for: infrequent configuration writes where cost matters more than endurance

Typical Applications

• Odometers and hour meters: Frequent non-volatile counter updates without wear
• Real-time data logging: Log sensor data at high rates without write delay or wear
• Power-fail safe storage: Write critical data instantly before power loss
• Event counters: Count events millions of times per day without EEPROM wear
• Industrial control: Real-time parameter storage in PLCs and control systems
• Wearable devices: High-endurance storage for health monitoring data
