General Description
The HT46R71D-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, HALT and wake-up functions,
watchdog timer, as well as low cost, enhance the versa-
tility of these devices to suit for a wide range of AD with
LCD application possibilities such as sensor signal pro-
cessing, scales, consumer products, subsystem con-
trollers, etc.
