A. HE80320S Introduction

HE80320S is a member of Jess Tech HE8000 series 8-bit CMOS micro-controller. This chip is a
Power Speech Controller. It built-in one internal Op-Amp, one 7-bit D/A converter and one
PWM output module to provide a speech output interface. Use the built-in 960K ROM can store
around 320 seconds of speech data (8KHz sampling rate ADPCM). Use external SRAM or Flash
RAM for recording function. The HE80320S provides a very simple and effective instruction set,
each instruction byte occupies only 1.5 clock cycle time, therefore, it is suitable to apply in the
high performance systems.

External Slow Clock pin .
Connecting with
32768Hz crystal or resistor
as slow clock and
providing clock source for
LCD display, TIMER 1,
Time-Base and other
internal blocks.

Mask Option settings :
MO_FCK/SCKN=00Slow Clock only

01Illegal
10Dual Clock
11Fast Clock only

MO_FOSCE=0Internal fast osc.

1External fast osc.

MO_FXTAL=0RC osc. for Fast Clock

1X'tal osc. for Fast Clock

MO_SXTAL=0RC for 32768Hz clock

1X'tal for 32768Hz clock

Use OP1and OP2 to switch among different operation
mode (NORMAL, SLOW, IDEL and SLEEP). In Dual
Clock mode, the main system clock is still the Fast
Clock. The 32768Hz clock is for LCD and timer1 only.

RSTP_N

System Reset

Level trigger, active low. Except for using this pin, using
mask option (MO_PORE=1) could enable IC build-in
power-on reset circuit.
Besides, MO_WDTE can set Watch Dog Timer :
MO_WDTE =0Disable Watch Dog Timer

=1Enable Watch Dog Timer

TSTP_P

Test Pin.

Please bond this pin and add a test point on PCB for
debugging. Leave this pin floating is OK.

PRTD[7:0]

8-pin bi-directional I/O
port. PRTD[7..2] as wake-
up pin. PRTD[7..6] as
external interrupt pin.

Mask Option
MO_CPP[7:0] =1 : Push-pull

= 0 : Open-drain.

Output must be "1" before reading whenever use them as
input (No tri-state structure).

PWMP

PWM positive output can
drive speaker or buzzer
directly.

Set the bit-2 of VOC register as one to turn on PWM

PWMN

PWM negative output can
drive speaker or buzzer
directly.

Set the bit-2 of VOC register as one to turn on PWM

DAC Voice Output

Set the bit-1(VO =1) of VOC register to turn on DAC
with VO output.

DAO

D/A output, for OP use

Set the bit-0(OP =1) of VOC register to turn on DAC
with VO output and also turn OP comparator on.

OPIN

Negative input of OP

comparator

OPIP

Positive input of OP

comparator

OPO

Output of OP comparator

Set the bit0(OP=1) of VOC register to turn on OP

comparator

VDD

Positive Power Input

GND

Power Ground Input

Adding 0.1mF capacitor as by-pass capacitor is between

VDD and GND is necessary
