HT46R53A/HT46R54A -- A/D Type 8-Bit OTP MCU
General Description
The HT46R53A/HT46R54A are 8-bit high performance, RISC architecture microcontroller devices specifically designed for A/D applicati*** that interface directly to analog signals, such as those from sensors. The advantages of low power c***umption, I/O flexibility, timer functi***, oscillator opti***, multi-channel A/D converter, Pulse Width Modulation function, HALT and wake-up functi***, watchdog timer, as well as low cost, enhance the versatility of these devices to suit a wide range of A/D application possibilities such as sensor signal processing, chargers, motor driving, industrial control, c***umer products, subsystem controllers, etc.
