General Description
The device are 8-bit, high performance, RISC architec-
ture microcontroller devices specifically designed for
A/D applications that interface directly to analog signals,
such as those from sensors.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, multi-channel A/D Converter, HALT
and wake-up functions, enhance the versatility of these
devices to suit a wide range of A/D application possibili-
ties such as sensor signal processing, etc.
The device provides two comparators and programma-
ble pulse generator (PPG). It is particularly suitable for
use in products such as induction cooker and home ap-
pliances.
