KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE82015 HE80000 SERIES A. HE82015 Introduction HE82015 is a member of 8-bit Micro-controller series developed by King Billion Electronics Ltd. It is a power speech controller. The 7-bit current-type D/A converter and PWM device provide the complete speech output mechanism. The 128K ROM Size can be used in the storage of speech (40 seconds at 3Kbytes per second). In order to simplify IC function, this IC have not exit follow list circuit, Slow Clock, Internal Power-ON Reset, TP automatic increase, Timer2 and Watch-dog Timer. Please pay attention. The instruction set of HE82015 are quite easy to learn and simple to use. Only about thirty instructions with four-type addressing mode are provided. Most of instructions take only 3 oscillator clocks (machine cycles). The processing power is enough to most of battery operation system. B. HE82015 Features z Operation Voltage： z System Clock： 2.4V – 5.5V DC ~ 8MHz @ 5.0V z z z z DC ~ 4MHz @ 2.4V 128K Bytes(64K Program ROM, 64K Data ROM) 128 Bytes. Normal (Fast) clock： 32.768K ~ 8MHz FAST、SLEEP Mode. Internal ROM： Internal RAM： Single Clock System ： Operation Mode： z 8 bit Bi-directional I/O port. Mask Option can select PUSH-PULL or OPEN DRAIN output mode for each I/O pin. z One 7-bit current-type DAC output. z PWM device. z Two external interrupts and one internal timer interrupt. z One 16-bit timer. (Clock Source reference by Fast Clock) z Instruction set： 32 instructions, 4 addressing mode. 7-bit DATA POINTER for RAM and 17-bit TABLE POINTER for ROM. 1 V3.3E HE82015 KING BILLION ELECTRONICS CO., LTD 駿 億 電 子 股 份 有 限 公 司 HE80000 SERIES C.

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 KB 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). J.
