HT83F02 -- External Voice Memory Flash MCU

General Description
The Flash type voice of MCU has Flash type Program Memory and Connect External flash through SPI Serial Interface. Offering users the convenience of Flash Memory multi-programming features, this device also includes a wide range of functions and features which include a voice synthesizer and tone generator.
This device is designed for applications which require multiple I/Os and sound effects, such as voice and melody. It can provide various sampling rates and beats, tone levels, tempos for speech synthesizer and melody generator. It also includes two integrated high quality, voltage type DAC outputs and voltage type PWM outputs.
This device is 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 12MHz at an operating voltage of 5V and include a power-down function to reduce power consumption. A full choice of HXT, ERC and HIRC oscillator functions are provided including a fully integrated system oscillator which requires no external components for its implementation.
The MCU flash voice memory capacity determine by user, into which the user can download their voice data.
