HE80128M Introduction HE80128M 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 384K ROM can store around 128 seconds of speech data (8KHz sampling rate ADPCM). Use external SRAM or Flash RAM for recording function. The HE80128M 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. B.

Application Circuit t4U.com .com DataShe e 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 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.
