HT83FXX -- Flash Type Voice OTP MCU (产品终止信息)

General Description

The flash type voice series of MCUs have OTP type Program Memory and Flash type Voice Memory.

The devices are 8-bit high performance microcontrollers which include a voice synthesizer and tone generator. They are designed for applications which require multiple I/Os and sound effects, such as voice and melody. The devices can provide various sampling rates and beats, tone levels, tempos for speech synthesizer and melody generator.

They also include two integrated high quality, voltage type DAC outputs and voltage type PWM outputs.

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 2.7V and include a power-down function to reduce power consumption.

The MCU flash voice memory capacity ranges from 2Mx8 bit to 128Kx8 bit, into which the user can download their voice data repeatedly.
