HT46RU75D-1 -- Dual Slope A/D Type MCU with LCD

General Description

The HT46RU75D-1 is an 8-bit high performance, RISC architecture microcontroller device specifically designed for A/D with LCD applications that interface directly to analog signals, such as those from sensors. The advantages of low power consumption, I/O flexibility, 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 processing, scales, consumer products, subsystem controllers, etc.
