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.

NOTE
The AVDD_AD, VREF are analog voltage input that need to separate with other digital
voltage input to reduce noise issue. For example, you can use on-chip regulator to be
the analog voltage source. Or you can refer to development board reference circuit.

Figure 8-2 ELAN eSL Series Application Circuit Diagram with A/D, D/A using BJT, SPI and PWM for 4.5V Support
NOTE
The AVDD_AD, VREF are analog voltage input that need to separate with other digital
voltage input to reduce noise issue. For example, you can use on-chip regulator to be
the analog voltage source. Or you can refer to development board reference circuit.
NOTE
For different package type, the system characteristic issue such as power
consumption due to IO pad floating must controlled by software. For example, if user
don’t bonding IO pad, you must set IO pad type is input with pull-up resister or output
to prevent power consumption.
