The V850E/IF3 incorporates four 16-bit interval timer M (TMM) channels, five 16-bit timer/event counter
AA (TAA) channels, two 16-bit timer/event counter AB (TAB) channels, and two 16-bit timer/event counter
T (TMT) channels, and can measure pulse interval widths or frequency, enable an inverter function for
motor control, and output a programmable pulse.
A watchdog timer is equipped to detect program loops, system abnormalities, etc.
It generates a non-maskable interrupt request signal (INTWDT) or internal reset signal (WDTRES) after an
overflow occurs.
The V850E/IF3 incorporates eight serial interface channels: for three asynchronous serial interface A
(UARTA) channels, one asynchronous serial interface B (UARTB) channel, three clocked serial interface B
(CSIB) channels, and one I

For UARTA, data is transferred via the TXDAn and RXDAn pins (n = 0 to 2).
For UARTB, data is transferred via the TXDB and RXDB pins.
For CSIB, data is transferred via the SOBn, SIBn, and SCKBn pins (n = 0 to 2).
For I
One channel is provided for each of the high-speed, high-resolution 12-bit A/D converters (ADC0, ADC1)
(total of two channels), which have five analog input pins respectively, and one channel is provided for the
10-bit A/D converter (ADC2), which has four analog input pins.
Both one of the ADC0 channels and three of the ADC1 channels include an operational amplifier and a
comparator so that these A/D converters can amplify an analog input voltage and detect overvoltage input.
An on-chip debug function supporting MINICUBE2 can be used, so that a simple, inexpensive debug
environment can be organized.
As shown below, the following ports have general-purpose port functions and control pin functions.
