Preface

Preface

Since the founding of the company, Holtek Semiconductor has concentrated much of its design ef
forts in the area of microcontroller development. Although supplying a wide range of semiconduc
tor devices,the microcontroller category has always been a key product category within the Holtek
range, and one which will continue to expand as their devices increase in functionality and matu
rity. By capitalizing on the substantial accumulated skills within its dedicated microcontroller devel
opment department, Holtek has been able to release a comprehensive range of high quality
low-cost microcontroller devices for a wide range of application areas. Many important application
areas have the need to digitize analog input signals, such as those which interface to external sen
sors, and to display the result on a Liquid Crystal Display. Applications that fall into this category
will all require an A/D converter to digitize the signals and an LCD driver function to display the re
sults. To address these needs, Holtek has developed its range of A/D with LCD microcontrollers,
which in addition to having all the features and functions of the A/D range of devices, also include
an LCD driver function that can directly interface to a custom Liquid Crystal Display, providing re­lated users with a fully integrated solution with which to measure and display analog signals. This
high level of device integration and consequent reduction in need for external components there­fore provide a high function low cost solution for any users with applications that require both ana­log signal processing and Liquid Crystal Display functions.

This handbook is divided into three parts for user convenience. Most details regarding general
datasheet information and device specification is located within Part I. Information related to
microcontroller programming such as device instruction set, instruction definition, and assembly
language directivesis found within Part II. Part III relates to the Holtek range ofDevelopment Tools
where information can be found on their installation and use.

By compiling all relevant data together in one handbook, we hope users of the Holtek range of A/D
with LCD Type microcontroller devices will have at their fingertips a useful, complete and simple
means to efficiently implement their microcontroller applications. Holtek's efforts to combine infor
mation on device specifications, programming and development tools into one publication have
produced a handbook which with careful use by the user should result in trouble free designs and
the maximum benefit being gained from the many features of Holtek microcontroller devices.
Holtek welcomes feedback and comments from our customers regarding further improvements.

Hardware Structure

This sectionis the main datasheet section of the A/D withLCD Type microcontrollerhandbook and
contains all the parameters and information related to the hardware. The information contained
provides designers with details on all the main hardware features of the A/D with LCD Type
microcontroller range which together with the programming section contains the information to en
able swift and successful implementation of user microcontroller applications. By proper consulta
tion of the relevant parts of this section, users can ensure that they make the most efficient use of
the flexible and multi-function features within the A/D with LCD Type microcontroller series.

Introduction

The HT46R62/HT46C62, HT46R63/HT46C63, HT46R64/HT46C64 and HT46R65/HT46C65
form the series of 8-bit high performance RISC architecture microcontrollers, designed especially
for product applications that interface directly to analog signals and which require to display the
measured dataon aLiquid Crystal Display. Device flexibility is enhanced with the usual features of
the other microcontroller range such as HALT and wake-up functions, integrated timer functions,
oscillator options, programmable frequency divider in addition to Pulse Width Modulator outputs
etc. These features combine to ensure applications require a minimum of external components
and therefore reduce overall product costs. Having the benefits of integrated analog to digital con­version functions which together with integrated LCD driver circuits and, in addition to the usual
Holtek advantages of low power consumption, high performance, I/O flexibility, as well as low cost,
these devices have the versatility to suit a wide range of application possibilities in areas such as
sensor signal processing and displaying, electronic metering, motor driving etc., for both industrial
and homeappliance application areas. Many features are common to all devices however, they dif
fer in areas such as I/O pin count, RAM and ROM capacity, timer number and size, A/D channels,
PWM outputs, LCD outputs etc.

The HT46R62, HT46R63, HT46R64 and HT46R65 are OTP devices offering the advantages of
easy and effective program updates, using the Holtek range of development and programming
tools. These devices provide the designer with the means for fast and low cost product develop
ment cycles. However, for applications that are at a mature state in their design process, the
HT46C62, HT46C63, HT46C64 and HT46C65 mask version devices offer a complementary de
vice for products with high volume and low cost demands. Fully pin and functionally compatible
with their OTP sister devices, such mask version devices provide the ideal substitute for products
which have gone beyond their development cycle and are facing cost down demands.

Description

Bidirectional 8-bit input/output port. Each individual bit
on this port can be configured as a wake-up input by a
configuration option. Software instructions determine if
the pin is a CMOS output or Schmitt Trigger input. Con
figuration options determine which pins on the port
have pull-high resistors. Pins PA0, PA1 and PA3 are
pin-shared with BZ, BZ
tion of which is chosen via configuration options.

Bidirectional 6-bit input/output port. Software instruc
tions determine if the pin is a CMOS output or Schmitt
Trigger input. Configuration options determine which
pins on the port have pull-high resistors. PB is
pin-shared with the A/D input pins. The A/D inputs are
selected via software instructions. Once selected as an
A/D input, the I/O function and pull-high resistor func
tions are disabled automatically.

Bidirectional 6-bit input/output port. Software instruc
tions determine if the pin is a CMOS output or Schmitt
Trigger input. Configuration options determine which
pins on the port have pull-high resistors. PD0~PD2 are
pin-shared with PWM0~PWM2, the function of each pin
is selected via a configuration option. Pins PD4 and
PD5 are pin-shared with external interrupt input pins
INT0

and INT1 respectively. Configuration options de­termine the interrupt enable/disable and the interrupt
low/high trigger type. Pin PD6 is pin-shared with the ex­ternal timer input pin TMR.

OSC1 and OSC2 are connected to an external RC net
work or external crystal (determined by configuration
option) for the internal system clock. For external RC
system clock operation, OSC2 is an output pin for 1/4
system clock. If an RTC oscillator on pins OSC3 and
OSC4 is used as a system clock, then the OSC1 and
OSC2 pins should be left floating.

OSC3 andOSC4 are connected to a 32768Hz crystal to
form a real time clock for timing purposes or to form a
system clock.

Bidirectional 8-bit input/output port. Each individual bit
on this port can be configured as a wake-up input by a
configuration option. Software instructions determine
if the pin is a CMOS output or Schmitt Trigger input.

pin-shared with the A/D input pins. The A/D inputs are
selected via software instructions. Once selected as
an A/D input, the I/O function and pull-high resistor
functions are disabled automatically.

OSC1 andOSC2 are connected to an external RC net­work or external crystal (determined by configuration
option) for the internal system clock. For external RC
system clock operation, OSC2 is an output pin for 1/4
system clock. If an RTC oscillator on pins OSC3 and
OSC4 is used as a system clock, then the OSC1 and
OSC2 pins should be left floating.

OSC3 and OSC4 are connected to a 32768Hz crystal
to form a real time clock for timing purposes or to form
a system clock.
