1. Overview

12-bit A/D converter (S12ADH)

(Products with 64 Kbytes of RAM)

 12 bits (4 channels × 2 units, 14 channels × 1 unit)

 12-bit resolution

 Minimum conversion time

0.9 µs per channel (when ADCLK operates at 60 MHz)

 Operating mode

Scan mode (single scan mode, continuous scan mode, or 3 group scan mode)

Group A priority control (only for 3 group scan mode)

 Sample-and-hold function

channel-dedicated sample-and-hold function (unit 0 × 3 channels, unit 1 × 3 channels)

included

 Sampling variable

Sampling time can be set up for each channel.

 Conversion function in order of arbitrarily selected channels (Serial conversion of the

same channel cannot be allowed)

 Double trigger mode (A/D conversion data duplicated)

 Three ways to start A/D conversion

Software trigger, synchronous trigger (MTU, GPTW, TMR, ELC), external trigger

 Prioritization in group scanning can be controlled among group A, B, and C.

 Digital comparison

Method: Comparison to detect voltages above or below thresholds and window

comparison

Measurement: Comparison of two results of conversion or comparison of a value in the

comparison register and a result of conversion

 Self-diagnostic function

 Detection of analog input disconnection

 Event linking by the ELC

 Input signal amplification function by the programmable gain amplifier

(unit 0 × 3 channels, unit 1 × 3 channels)

12-bit D/A converter (R12DAb)

 2 channels

 12-bit resolution

 Output voltage: 0 V to AVCC2

 Capable of providing as a reference voltage for comparator

 Event linking by the ELC

Comparator C (CMPCa)

 6 channels

 Function to compare the reference voltage and the analog input voltage

 Reference voltage is selectable from 4 inputs

 Analog input voltage is selectable from 4 inputs

 Digital filtering
