General Description
The HT45R06 is an 8-bit high performance, RISC archi-
tecture microcontroller devices specifically designed for
cost-effective multiple I/O control product applications.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, watchdog timer,
buzzer driver, multi-channel A/D converter, Pulse Width
Modulation function, HALT and wake-up functions,
enhance the versatility of these devices to suit a wide
range of A/D application possibilities such as security
systems, smoke detectors and smart tags.
