A. HE80068L Introduction
HE80068L is a 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 208K ROM can store around 68 seconds of speech data (6KHz
sampling rate ADPCM). Use external SRAM or Flash RAM for recording function.
The HE80068L 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.
Connect 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 Timer1 only.
