HE80068S Introduction
HE80068S 8-bit CMOS micro-controller. This chip Power Speech Controller. built-in 7-bit converter output module provide speech output interfaces. built-in 208K store around seconds speech data (6KHz sampling rate ADPCM). simply function this functions removed Slow Clock, Internal Power-On Reset, Timer2, Watch-dig Timer. Please note. HE80068S provides very simple effective instruction set, each instruction byte occupies only clock cycle time, therefore, suitable apply high performance systems.

Application Circuit
Important Note
accessing address large than 64KB, users must update first, then TPL. Only this order, pre-charge circuit will work correctly. waiting necessary before instruction executed since Data speed ROM. Users emulate this accessing process ICE. delay should added firmware. 64KB Update r_tpp, r_tph, r_tpl Data pre-charge pre-charge 5us,, Data Please bonds TSTP_P, RSTP_N PRTD[7:0] with test point (can soldered probed) can, then JESS some testing PCB. Neither connection necessary TSTP_P. following figure example (Testing point with through hole.)
