HT46R75D-3
Overview
The HT46R75D-3 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, HALT and wake-up functions, watchdog timer, as well as low cost, enhance the versatility of these devices to suit for a wide range of AD with LCD application possibilities such as sensor signal processing, scales, consumer products, subsystem controllers, etc. 1 July 19, 2011.
