DESCRIPTION
The MB90980 series is a 16-bit general-purpose FUJITSU microcontroller designed for process control in con-
sumer devices and other applications requiring high-speed real-time processing.
The F2MC-16LX CPU core instruction set retains the AT architecture of the F2MC*1 family, with additional instruc-
tions for high-level languages, expanded addressing mode, enhanced multiply-drive instructions, and complete
bit processing. In addition, a 32-bit accumulator is provided to enable long-word processing.
The MB90980 series features embedded peripheral resources including 8/16-bit PPG, expanded I/O serial inter-
face, UART, 10-bit A/D converter, 16-bit I/O timer, 8/16-bit up/down-counter, PWC timer, I2C*2 interface, DTP/
external interrupt, chip select, and 16-bit reload timer.
*1 : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
*2 : Purchase of Fujitsu I2C components conveys a license under the Philips I2C Patent Rights to use, these
components in an I2C system provided that the system conforms to the I2C standard Specification as defined by
Philips.

*1 : 3V/5V I/F pin : All pins should be for 3 V power supply without P24 to P27, P30 to P37, P40 to P42,
P70 to P74, P76, and P77.
*2 : P76/P77 pins are N-ch open drain pins (without P-ch) at built-in I2C.
*3 : It is setting of Jumper switch (TOOL VCC) when Emulator (MB2147-01) is used.
Please refer to the hardware manual of MB2147-01 or MB2147-20 (“3.3 Emulator-dedicated Power Supply
Switching”) about details.
Note : Ensure that you must write to Flash at VCC = 3.13 V to 3.60 V (3.3 V + 10%, 5%) .
