About

High performance

The new F²MC 8FX CISC CPU has a maximum operating frequency of 16.25 MHz and a minimum instruction execution time of 61.5 ns delivering superior CPU core performance for an 8-bit CPU. The number of cycles of each instruction has been optimized to deliver the required processing capacity at relatively low frequencies, helping reduce power consumption.

Composite timer

The built-in composite timer can be programmatically selected from the PWM, PWC, interval timer, and input capture functions for each channel, enabling the timer to flexibly support a variety of system requirements.

Highly reliable flash

The product line features a variety of flash, ROM, and RAM configurations. The highly reliable flash guarantees data retention for 20 years with 100,000 write/erase cycles. A flash security function prevents unauthorized external reading of the program. The system is capable of EEPROM emulation using the built-in dual-operation flash.

Other features

The product includes UART and I²C interfaces. The oscillator, reset IC, and EEPROM are built into the microcontroller, helping reduce costs. The devices, which feature 16-bit arithmetic operation, can be configured for various low-power-consumption modes. Other features include BIT-branch-test and BIT-test-manipulation instructions, an optional main-clock and sub-clock resources, an external clock, an external interrupt with an edge detector interrupt capability, an on-chip debugging unit, a hardware/software watchdog, a low-voltage detector, and programmable port-input voltage levels. The devices are available in a 64-pin package.
