HE83145

      HE83145 is a member of Jess Tech HE80000 series 8-bit CMOS micro-controller. This IC can share the LCD pin and I/O pin (From 1024-dot of LCD driver + 8 Bit I/O Port) ... (768-dot of LCD driver + 24 Bit I/O Port)etc, 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, graphic, text etc. It can be applicable to the medium systems such as Small-Scale Dictionary, Data Bank, Pocket Dialer, Educational Toy, Digital Voice Recording System etc. The instruction set of HE83145 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.
      HE83145 Features 2.4V ­ 5.2V DC ~ 8MHz @ 5.0V DC ~ 4MHz @ 2.4V ROM size: 128K Bytes(64K Program ROM + 64K Data ROM) RAM size: 256 Bytes Dual Clock: Normal(Fast) clock: 32.768K ~ 8MHz Slow clock: 32.768KHz Operating Mode: DUAL FASTSLOWIDLESLEEP Mode 8~24 bit bi-directional I/O port, Mask Option can select PUSH-PULL or OPEN DRAIN output mode for each I/O pin. 8 of them are shared with LCD segment pins. One built-in OP Comparator. 1024~768 dots LCD driver (AB TYPE selectable) One 7-bit current-type DAC output. PWM device. Built-in DTMF Generator Two external interrupts and three internal timer interrupts. Two 16-bit timer and one Time-Base timer. Instruction Set : 32 Instructions, 4 addressing mode. 8-bit DATA POINTER for RAM and 17bit TABLE POINTER for ROM. Operating Voltage: Operation frequency Range:
      Application of HE83145: Applicable to the medium systems such as Small-Scale Dictionary, Data Bank, Pocket Dialer, Educational Toy, Digital Voice Recording System etc.
