HE80256S Introduction
HE80256S member Jess Tech HE8000 series 8-bit CMOS micro-controller. This chip Power Speech Controller. built-in internal Op-Amp, 7-bit converter output module provide speech output interface. built-in 768K store around seconds speech data (8KHz sampling rate ADPCM). external SRAM Flash recording function. HE80256S 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. 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.)
