A. HE80085S Introduction
HE80085S 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 256K ROM can store around 85 seconds of speech data (6KHz
sampling rate ADPCM). Use external SRAM or Flash RAM for recording function.
The HE80085S 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.

H. Application Circuit
I. Important Note
For accessing any address large than 64KB, users must update TPP first, TPH then TPL. Only by
this order, the pre-charge circuit of ROM will work correctly. 5us waiting is necessary before LDV
instruction is executed since Data ROM is a low speed ROM. Users can not emulate this
accessing process in ICE. So 5us delay should be added by firmware.
Please bonds the TSTP_P, RSTP_N and PRTD[7:0] with test point on PCB (can be soldered and
probed) as you can, then JESS can do some IC testing job on PCB. Neither VDD nor GND
connection is necessary for TSTP_P. The following figure is an example (Testing point with
through hole.)

HE80 Series PWM application
Description:
For HE80 PWM application, the following points must be bare in mind.
1.
The PWM output can direct drive buzzer.
2.
For direct drive speaker, it must use 32
or above speaker.
3.
For speaker application, it must add capacitors between IC's VDD ground and its PWM
output, see below figure.
Note: the 1uF capacitor must be connected near IC's
