HE80170L introduction HE80170L 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 512k rom can store around 170 seconds of speech data (8khz sampling rate adpcm). use external sram or flash ram for recording function. the HE80170L 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.
