General Description

The HT46R24/HT46C24 are 8-bit, high performance,

RISC architecture microcontroller devices specifically

designed for A/D applications that interface directly to

analog signals, such as those from sensors. The mask

version HT46C24 is fully pin and functionally compatible

with the OTP version HT46R24 device.

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

ity, programmable frequency divider, timer functions,

oscillator options, multi-channel A/D Converter, Pulse

Width Modulation function, I

C interface, HALT and

wake-up functions, enhance the versatility of these de-

vices to suit a wide range of A/D application possibilities

such as sensor signal processing, motor driving, indus-

trial control, consumer products, subsystem controllers,

etc.

Description

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

input by option (bit option). Software instructions determine the CMOS out-

put or Schmitt trigger input with or without pull-high resistor (determined by

pull-high options: bit option). The PFD and INT are pin-shared with PA3

and PA5, respectively. Once the I

C Bus function is used, the internal reg-

isters related to PA6 and PA7 cannot be used.

I/O

Pull-high

Bidirectional 8-bits 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 se-

lected as an A/D input (by using software control), the I/O function and

pull-high resistor are automatically disabled.

Pull-high

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

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

mine by pull-high option: byte option).

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

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

The PWM0 output function is pin-shared with PD0.

The PWM1 output function is pin-shared with PD1 and TMR1.

(determined by pull-high option: byte option)

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

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

termined by pull-high option: byte option). The PWM0/PWM1/PWM2/

PWM3 output function are pin-shared with PD0/PD1/PD2/PD3 (depending

on the PWM options).

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

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

mine by pull-high option: byte option).

Timer/Event Counter 0 Schmitt trigger input (without pull-high resistor)

Timer/Event Counter 1 Schmitt trigger input (without pull-high resistor).

Schmitt trigger reset input, active low

Negative power supply, ground

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 terminal for 1/4 system clock.
