eSL Series
16 Bits DSP Sound Processor
1 General Description
The ELAN eSL Series IC is a 16-bit DSP Sound Processor with multi-channel speech
and instrument playback. It is based on ELAN 16-bit DSP platform. The series has a
powerful 16-bit DSP architecture that handles most of the speech/melody functions.
Speech and melody can be played back simultaneously. The speech synthesis is
implemented by software, and it supports a wide range of compression bit rates and
various volume levels. The ELAN eSL Series provides real instrument waveform to
obtain good quality melody. The ELAN eSL peripheral includes ADC, RTC, Timer,
WDT, SPI, DAC, PWM, etc.
The ELAN eSL Series IC offer Fast, Sleep, Green, and Slow modes of operation.
The use of Green/Slow mode will further reduce the power consumption. Green
mode also provides RTC function for wake-up purposes.
The ELAN eSL Series enhanced features make it suitable for versatile voice and
sound effect product applications. These enhanced versatile features allow users to
create products with a wide variety of new fancy ideas.
The ELAN eSL Series has extreme high performance in speech application based on
powerful DSP architecture and good algorithm in audio compression.
