■ OUTLINE
The MB90220 series of general-purpose high-performance 16-bit microcontrollers has been developed primarily for applications that demand high-speed real-time processing and is suited for industrial applications, office automation equipment, process control, and other applications. The F2MC-16F CPU is based on the F2MC*-16 Family with improved high-level language support functions and task switching functions, as well as additional addressing modes.
On-chip peripheral resources include a 4-channel PWC timer, a 4-channel ICU (Input Capture Unit), a 1-channel 24-bit timer counter, an 8-channel OCU (Output Compare Unit), a 6-channel 16-bit reload timer, a 2-channel 16-bit PPG timer, a 10-bit A/D converter with 16 inputs, and a 4-channel serial port with a UART function (one channel includes the CTS function).
