SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER

32171 Group
Built-in Two Independent A-D Converters
The microcomputer contains two 16-channel converters with
10-bit resolution (A-D0 converter and A-D1 converter). In
addition to single conversion on each channel, continuous
A-D conversion on a combined group of 4, 8, and 16 chan-
nels is possible. The A-D converted value can be read out in
either 10 bits or 8 bits.

Interrupt request generation
When A-D conversion is finished, when comparate operation is finished, when single-shot
scan is finished, or when one cycle of continuous scan is finished.
DMA transfer request generation
When A-D conversion is finished, when comparate operation is finished, when single-shot
scan is finished, or when one cycle of continuous scan is finished.
Note 1: The rated value of conversion accuracy here is that of the microcomputer's own as a single unit which can be exhibited when the
microcomputer is used in an environment where it may not be affected by the power supply wiring or noise on the board.
Note 2: When input clock (XIN) = 10 MHz, f(BCLK) = 20 MHz.
In addition to ordinary A-D conversion, the converters sup-
port comparator mode in which the set value and A-D con-
verted value are compared to determine which is larger or
smaller than the other.
When A-D conversion is finished, the converters can generated
a DMA transfer request, as well as an interrupt.
The A-D converters are interfaced using a dedicated power
supply to allow for connections to the peripheral circuits op-
erating with 5V or 3.3V.
