HT83B60 -- Voice Mask MCU

General Description

The HT83B60 is the Mask version of the HT83F02 but also includes an integrated 8M bits of Voice ROM, connected to the MCU by an internal SPI Serial Interface. This 8-bit high performance microcontroller includes a wide range of functions and special audio 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 also includes an integrated high quality, voltage type DAC as well as a PWM generator.

This device will form an excellent solution 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 includes power-down functions to reduce power consumption. A full choice of oscillator functions are provided including a fully integrated system oscillator which requires no external components for its implementation.
