F²MC-16LX MB90820B Series

MB90822B/823B/F822B/F823B/F828B/V820B

■ DESCRIPTION

The MB90820B series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control

applications which require high-speed real-time processing, such as consumer products.

While inheriting the AT architecture of the F²MC family, the instruction set for the F²MC-16LX CPU core of the

MB90820B series incorporates additional instructions for high-level languages, supports extended addressing

modes, and contains enhanced multiplication and division instructions as well as a substantial collection of

improved bit manipulation instructions. In addition, the MB90820B series has an on-chip 32-bit accumulator which

enables processing of long-word data.

The peripheral resources integrated in the MB90820B series include : an 8/10-bit A/D converter, 8-bit D/A con-

verters, UARTs (SCI) 0, 1, multi-functional timer (16-bit free-run timer, input capture units (ICUs) 0 to 3, output

compare units (OCUs) 0 to 5, 16-bit PPG timer 0, waveform generator), 16-bit PPG timer 1, 2, PWC 0, 1, 16-bit

reload timer 0, 1 and DTP/external interrupt.

Note : F²MC is the abbreviation of FUJITSU Flexible Microcontroller.

■ FEATURES

• Minimum execution time of instruction : 42 ns / 4 MHz oscillation (uses PLL clock multiplication) maximum

multiplier = 6

• Maximum memory space 16 M bytes, Linear/bank access

• Instruction set optimized for controller applications

Supported data types : bit, byte, word, and long-word types

Standard addressing modes : 23 types

32-bit accumulator enhancing high-precision operations

Signed multiplication/division instructions and enhanced RETI instructions
