This IC has built-in 320-dot LCD driver. PWM device provide the complete speech output mechanism. The 256K ROM Size can storage around 80 second’s speech. This IC is applicable to the small/medium systems such as LCD Games and Perpetual Calendar etc. This IC is very easy to learn and use. Most of instructions take only 3 oscillator clocks (machine cycles). As a result this IC is suitable for the applications that require higher performance system. B.HE83124 Features z z Operation Voltage： System Clock： 2.2V – 5.5V DC ~ 8MHz @ 5.0V DC ~ 4MHz @ 2.2V 256K Bytes(64K Program ROM+192K Data ROM) 256 Bytes Normal (Fast) clock： 32.768K ~ 8MHz Slow clock： 32.768KHz DUAL、FAST、SLOW、IDLE、SLEEP Mode. z z z Internal ROM： Internal RAM： Dual Clock System ： z Operation Mode： z z z With WDT (WATCH DOG TIMER) to prevent deadlock condition. 8-bit Bi-directional I/O port. Mask Option can select PUSH-PULL or OPEN DRAIN output mode for each I/O pin. 320 dots LCD driver (A、B TYPE selectable). z z z z PWM device. Two external interrupts and two internal timers interrupts. Two 16-bit timers. Instruction set： 32 instructions, 4 addressing mode. 8-bit DATA POINTER for RAM and 18-bit TABLE POINTER for ROM. C.
