A. HE80042M Introduction
HE80042M 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 128K ROM can store
around 42 seconds of speech data (8KHz sampling rate ADPCM). Use external SRAM or Flash
RAM for recording function.
The HE80042M 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 Fast Clock pin.
Connecting to crystal or
RC to generate 32.768KHz
~ 8MHz frequency.
Mask Option settings :

10Dual Clock
11Fast Clock only
MO_FOSCE=0Internal fast oscillation

I,
O
External Slow Clock pin.
Connecting with 32768Hz
crystal or resistor as slow
clock and providing clock
source for LCD display,
TIMER1, Time-Base and
other internal blocks.
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 OP1 and 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 Timer 1 only.
