MC*
1
-16L family designed
to be combined with an ASIC (Application Specific IC) core. The MB90670/675 series is a high-performance
general-purpose 16-bit microcontroller for high-speed real-time processing in various industrial equipment, OA
equipment, and process control.
The instruction set of F
2
MC-16L CPU core inherits AT architecture of F
2
MC-8 family with additional instruction
sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and en-
hanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long word data
(32-bit).
The MB90670/675 series has peripheral resources of UART0, UART1(SCI), an 8/10-bit A/D converter, an
8/16-bit PPG timer, a 16-bit reload timer, a 24-bit free run timer, an output compare (OCU), an input capture (ICU),
DTP/external interrupt circuit, an I
