A. Introduction
HE84771 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. User
can chose any one of combination among 32COM4096 dots LCD Driver + 24 Bit I/O Port...3328
dots LCD Driver + 48 Bit I/O Portor 48COM
5376 dots LCD Driver + 24 Bit I/O Port...4224 dots
LCD Driver + 48 Bit I/O Portor 64COM
6144 dots LCD Driver + 24 Bit I/O Port...4608 dots LCD
Driver + 48 Bit I/O Portor 80COM6400 dots LCD Driver + 24 Bit I/O Port...4480 dots LCD
Driver + 48 Bit I/O Port. Users can choose one of LCD configuration through "Mask Option". With
built-in regulator circuit, LCD display will be stable. The built-in OP comparator can be used with
(lightvoicetemperaturehumility) sensor and used as battery low detection. 7-bit current-type D/A
converter and PWM device provide the complete speech output mechanism. The 1M ROM Size can be
used in the storage of speechgraphictext etc.. It can be used in TranslatorData BankPocket Dialer
Educational ToyDigital Voice Recording System etc
The instruction set of HE8XXXX are quite easy to learn and simple to use. Only about thirty instructions
with four-type addressing mode are provided. Most of instructions take only 3 oscillator clocks (machine
cycles). The processing power is enough to most of battery operation system.
B. HE84771 Features
Operation Voltage 2.4V 3.6V
System Clock
4MHz ~ 8MHz
Internal ROM
1M Bytes(256K Program ROM+768K Data ROM)
Internal RAM 16K
Bytes
Dual Clock System Normal(Fast) clock:
32.768K ~ 8MHz(No Internal Clock)
Slow
clock:
32.768KHz
Operation Mode DUALFASTSLOWIDLESLEEP Mode.
With WDT (WATCH DOG TIMER) to prevent deadlock condition.
24~48 bit Bi-directional I/O port.
Mask Option can select PUSH-PULL or OPEN DRAIN output
mode for each I/O pin. 24 of them are shared with LCD segment pins.
The new built-in hardware auto scan keyboard (4*20) (shared with LCD SEG Pin) not only reduces
the hardware cost, but also reduces the firmware effort.
One built-in OP comparator.
One Voltage Detector with two detecting threshold Vth. (Vth=2.4V/2.4v).
Users can select any one of four LCD configuration---32COM*128SEG LCD , 48COM*112SEG
LCD , 64COM*96SEG LCD or 80COM*80SEG LCD. All of LCD configuration are B
TYPE(please refer to HE80000 user's manual, section 4.3.9 LCD control register)It is built-in
type-III regulator, the LCD can display stably. The highest LCD voltage LVP must small than 8.5
Volt.

Normally, The LCD refresh rate is around 64 Hz. But for this IC, 32 COM configuration ~= 170 Hz
and 48 COM configuration ~= 110 Hz
One 7-bit current-type DAC output.
PWM device. (No Rate Selection, connect with VDD & PWMP)
