HT46R73D-1A -- Dual Slope A/D Type MCU with LCD (限用產品)
General Description
The HT46R73D-1A 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.
