MB90497G/F497G/F498G/V495G
■
DESCRIPTION
The MB90495G Series is a general-purpose, high-performance 16-bit microcontroller. It was designed for devices
like consumer electronics, which require high-speed, real-time process control. This series features an on-chip
full-CAN interface.
In addition to being backwards compatible with the F
2
MC* family architecture, the instruction set has been ex-
panded to add support for high-level language instructions, expanded addressing mode, and enhanced multiply/
divide and bit processing instructions. A 32-bit accumulator is also provided, making it possible to process long
word (32-bit) data.
The MB90495G Series peripheral resources include on chip 8/10-bit A/D converter, UART (SCI) 0/1, 8/16-bit
PPG timer, 16-bit I/O timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU) ) , and CAN controller.

MC is the abbreviation of FUJITSU Flexible Microcontroller.

PRODUCT COMPARISON
Memory Size
When evaluating with evaluation chips and other means, take careful note of the different between the evaluation
chip and the chip actually used. Take particular note of the following.
• While the MB90V495G does not feature an on-chip ROM, the dedicated development tool can be used to
achieve operation equivalent to a product with built-in ROM. Therefore, the ROM size is configured by the
development tool.
