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 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 mode, Sleep mode, Green mode, and Slow mode of operation. The use of Green/Slow mode will further reduce power consumption. The Green mode also provides RTC function for wake-up purpose. The ELAN eSL Series enhanced features make it suitable for versatile voice and sound effect product applications; besides, users are motivated to explore a wide variety of new creative ideas and products. The ELAN eSL Series has extreme high performance in speech application based on powerful DSP architecture and good algorithm in audio compression. We provide up to 2-channel speech with different channel sample rate or 1-channel speech + 8channel melody. 2 Features MCU • • • • • 16-bit RISC CPU architecture CPU clock: 20MHz @ 3.3V Programmable PLL Four CPU operation modes: fast, slow, green, sleep Powerful DSP Instruction Set supports multiplication, division, repeat, loop and soft interrupt instructions • Saturation mode supported for multimedia applications • Eight general purpose registers (GPR) • 21 interrupt sources with 2-level priority Memory • 32K-word program memory • 2K-word data RAM • 128/256/512K-word data ROM Peripherals • Real Time Clock (RTC) with wake-up function • Four 8-bit timers, two general purpose timers, two multiple-function timers Product Specification (V0.7) 06.14.2006 (This specification is subject to change without further notice) •1 eSL Series 16 Bits DSP Sound Processor • • • • 8-bit Watchdog Timer (WDT) with general purpose timer capability 40 GPIO + 8 Output Serial Peripheral Interface (SPI) 12-bit Analog to Digital Converter (ADC) with touch panel and MIC inputs Audio • • • • • • • 12-bit current-steering Digital to Analog Converter (DAC) 10-bit resolution Pulse Width Modulation (PWM) Built-in software voice synthesizer (0.8K ~ 40Kbps@8kHz) Multiple flash with volume level option Control port output value directly by waveform (waveform control port) Support mark code in waveform Up to 2-channel speech with different channel sample rate or 1-channel speech + 8-channel melody 3 Block Diagram Program Co unter I/O Space (SFR) I/O Direct ADC RAM Addressing Control Unit DAC 17 x17 Multiplier / Di vi der (+16 bi t ALU) ALU Bus Bus INT PWM I/O Instructi on Decoder G eneral Purpose Regi sters Data Reg Addressing Addressing ROM Port A~D Timer RTC A CC D WDT Status Reg SPI OSC/PLL R AM C o nto l S ig na ls Figure 2-1 ELAN eSL System Block Diagram 2• Product Specification (V0.7) 06.14.2006 (This specification is subject to change without further notice) eSL Series 16 Bits DSP Sound Processor 4 Selection Table The ELAN eSL Series integrates an extensive range of features, most of which are common to all devices, except for some distinctive features like Data ROM and Coding Type.
