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
2M´8 bit to 128K´8 bit, into which the user can down-
load their voice data repeatedly.
