F2MC-16F MB90246A Series
MB90246A
s DESCRIPTION
The MB90246A series is a 16-bit microcontroller optimum to control mechatronics such as a hard disk drive unit.
The instruction set of F2MC-16F CPU core inherits AT architecture of F2MC*-16/16H family with additional
instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division
instructions, and enhanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for
processing long word data (32-bit).
The MB90246A series contains a production addition unit as peripheral resources for enabling easy
implementation of functions supported by IIR and FIR digital filters. It also supports a wealth of peripheral functions
including:
- an 8/10-bit A/D converter having eight channels;
- an 8-bit D/A converter having three channels;
- UART;
- an 8-bit PWM timer having four channels;
- a timer having three plus one channels;
- an input capture (ICU) having two channels; and
- a DTP/external interrupt circuit having four channels.
* : F2MC stands for FUJITSU Flexible Microcontroller.
