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

■ DIFFERENCES AMONG PRODUCTS
Memory Size
In evaluation with an evaluation product, note the difference between the evaluation product and the product
actually used. The following items must be taken into consideration.
• The MB90V820B does not have an internal ROM, however, operations equivalent to chips with an internal
ROM can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of
the development tool.
• In the MB90V820B, images from FF8000H to FFFFFFH are mapped to bank 00, and FE0000H to FF7FFFH are
mapped to bank FE and bank FF only. (This setting can be changed by configuring the development tool.)
• In the MB90822B/F822B/F828B, images from FF8000H to FFFFFFH are mapped to bank 00, and FF0000H to
FF7FFFH are mapped to bank FF only. In the MB90823B/F823B/F828B, images from FF8000H to FFFFFFH
are mapped to bank 00, and FE0000H to FF7FFFH are mapped to bank FE and bank FF only.
Clock Supervisor Function
The clock supervisor is built-in in MB90F828B only. Note that the evaluation products and products actually used
are different when evaluating evaluation products. Please contact the sales representatives for more information
on evaluation of this function.
Modify ROM data
The registers include this function between 001FF0H and 001FF5H which overlap the RAM area of MB90F828B.
Do not access to the RAM when using this function in MB90F282B.
