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 mel-
ody. 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 out-
puts.
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.
