General Description
The HT46RU75D-1 is an 8-bit high performance, RISC
architecture microcontroller device specifically de-
signed for A/D with LCD applications that interface di-
rectly to analog signals, such as those from sensors.
The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, Dual slope A/D
converter, LCD display, UART function, HALT and
wake-up functions, watchdog timer, as well as low cost,
provide the flexibility to suit a wide range of AD with LCD
application possibilities such as sensor signal process-
ing, scales, consumer products, subsystem controllers,
etc.
