1 / 79 page  HT86BXX/HT86BRXX Enhanced Voice 8-Bit MCU Rev. 1.60 1 October 20, 2009 General Description The Voice type series of MCUs are 8-bit high perfor- mance microcontrollers which include a voice synthe- sizer and tone generator. They are designed for applications which require multiple I/Os and sound ef- fects, such as voice and melody. The devices can pro- vide various sampling rates and beats, tone levels, tempos for speech synthesizer and melody generator. They also include an integrated high quality, voltage type DAC output. The external interrupt can be trig- gered with falling edges or both falling and rising edges. The devices are excellent solutions for versatile voice and sound effect product applications with their efficient MCU instructions providing the user with programming capability for powerful custom applications. The system frequency can be up to 8MHz at an operating voltage of 2.2V and include a power-down function to reduce power consumption. Features · Operating voltage: 2.2V~5.5V · System clock: 4MHz~8MHz · Crystal and RC system oscillator · 16/20/24 I/O pins · 8K´16-bit Program Memory · 192´8/384´8-bit Data Memory · External interrupt input · Three 8-bit programmable Timers with overflow interrupt and 8-stage prescaler · 12-bit high quality voltage type D/A output · PWM circuit direct audio output · External RC oscillator converter · 8 capacitor/resistor sensor input · Watchdog timer function · 8-level subroutine nesting · Low voltage reset function · Integrated voice ROM with various capacities · Power-down function and wake-up feature reduce power consumption · Up to 0.5ms instruction cycle with 8MHz system clock at VDD=5V · 63 powerful instructions Technical Document · Application Note - HA0075E MCU Reset and Oscillator Circuits Application Note |
