General Description

The HT46R64/HT46C64 are 8-bit, high performance,

RISC architecture microcontroller devices specifically

designed for A/D product applications that interface di-

rectly to analog signals and which require LCD Inter-

face. The mask version HT46C64 is fully pin and

functionally compatible with the OTP version HT46R64

device.

The advantages of low power consumption, I/O flexibil-

ity, timer functions, oscillator options, multi-channel A/D

Converter, Pulse Width Modulation function, HALT and

wake-up functions, in addition to a flexible and

configurable LCD interface enhance the versatility of

these devices to control a wide range of applications re-

quiring analog signal processing and LCD interfacing,

such as electronic metering, environmental monitoring,

handheld measurement tools, motor driving, etc., for

both industrial and home appliance application areas.

Description

Bidirectional 8-bit input/output port. Each bit can be configured as wake-up in-

put by option. Software instructions determine the CMOS output or Schmitt

Trigger input with or without pull-high resistor (determined by pull-high op-

tions: bit option). The BZ, BZ and PFD are pin-shared with PA0, PA1 and

PA3, respectively.

I/O

Pull-high

Bidirectional 8-bit input/output port. Software instructions determine the

CMOS output, Schmitt trigger input with or without pull-high resistor (deter-

mined by pull-high option: bit option) or A/D input. Once a PB line is selected

as an A/D input (by using software control), the I/O function and pull-high re-

sistor are disabled automatically.

I/O

Pull-high

PWM

Bidirectional 4-bit input/output port. Software instructions determine the

CMOS output, Schmitt trigger input with or without a pull-high resistor (deter-

mined by pull-high option: bit option). The PWM0/PWM1/PWM2/PWM3 out-

put function are pin-shared with PD0/PD1/PD2/PD3 (dependent on PWM

options).

Bidirectional 4-bit input/output port. Software instructions determine the

CMOS output, Schmitt trigger input with or without a pull-high resistor (deter-

mined by pull-high option: bit option). The INT0, INT1, TMR0 and TMR1 are

pin-shared with PD4/PD5/PD6/PD7.

SEG32 can be set as a segment or as a common output driver for LCD panel

by options. COM0~COM2 are outputs for LCD panel plate.

LCD driver outputs for LCD panel segments. SEG0~SEG23 can be optioned

as logical outputs.

OSC1 and OSC2 are connected to an RC network or a crystal (by options) for

the internal system clock. In the case of RC operation, OSC2 is the output ter-

minal for 1/4 system clock. The system clock may come from the RTC oscilla-

tor. If the system clock comes from RTCOSC, these two pins can be floating.

Real time clock oscillators. OSC3 and OSC4 are connected to a 32768Hz

crystal oscillator for timing purposes or to a system clock source (depending

on the options). No built-in capacitor
