HT86072

The HT86072 is designed as one kind of 8-bit high performance microcontroller with voice synthesizer and tone generator, that can be used in (1)Intelligent educational leisure products;(2)High end leisure product controllers;(3)Sound effect generators;(4)Alert and warning systems. This device is also excellent for versatile voice and sound effect product applications, and provides various sampling rates and beats, tone levels, tempos for speech synthesizer and melody generator. It has a single built-in high quality, D/A output.

Features of the HT86072 are:(1)Built-in voice ROM in various capacity; (2)One optional 32768Hz crystal oscillator for RTC time base (8-bit counter with 3-bit prescaler); (3)Watchdog Timer; (4)8-level subroutine nesting; (5)HALT function and wake-up feature reduce power consumption; (6)Up to 1 us (0.5 us) instruction cycle with 4MHz (8MHz) system clock; (7)Support 16-bit table read instruction (TBLP, TBHP); (8)63 powerful and efficient instructions; (9)68-pin PLCC package; (10)Operating voltage: 2.4V to 5.2V; (11)Build-in low supply voltage detection circuit (2.2V or 3.3V); (12)System clock: 4MHz to 8MHz; (13)Crystal or RC oscillator for system clock; (14)24 I/O pins with 4 shared pins included; (15)8K x 16-bit program ROM; (16)208 x 8-bit RAM; (17)One external interrupt input; (18)Three 16-bit programmable timer counter and overflow interrupts; (19)12-bit high quality D/A output by transistor or HT82V733.

The absolute maximum ratings of the HT86072 can be summarized as:(1)Supply Voltage: 2.4V to 5.2V;(2)Input Voltage: VSS-0.3V to VDD+0.3V;(3)Storage Temperature: -50 to 125 ;(4)Operating Temperature: -20 to 70 .
