DESCRIPTION
MB90660A series microcontrollers are 16-bit microcontrollers optimized for high speed realtime processing of consumer equipment and system control of air conditioner video cameras, VCRs, and copiers. Based on the F2MC*-16 CPU core, an F2MC-16L is used as the CPU. This CPU includes high-level language-support instructions and robust task switching instructions, and additional addressing modes.

FEATURES
• F2MC-16L CPU
• Minimum execution time: 62.5 ns/4 MHz oscillation (uses PLL multiplier): fastest speed at quadruple operation
• Instruction set optimized for controller applications Upward compatibility at object level with the F2MC-16(H) Various data types (bit, byte, word, long-word) Higher speed due to review of instruction cycle Expanded addressing modes: 23 types High coding efficiency Two access methods (bank system or linear pointer) Improved multiply-and-divide instructions (additional signed instructions) Improved high-precision operation with 32-bit accumulator Extended intelligent I/O services (access area extended by 64 Kbytes) Large memory space: 16 Mbytes
