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 eAMS Series provides real instrument waveform to obtain good quality melody. The ELAN eAMS peripheral includes RTC, Timer, WDT, DAC, PWM, etc. The ELAN eAMS Series IC’s offer Fast mode, Sleep mode, Green mode, and Slow mode 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 eAMS 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 eAMS Series have extreme high performance in melody application based on powerful DSP architecture and good algorithm in audio compression. 2 Features MCU • 16-bit RISC CPU architecture • CPU clock: 20 MHz @ 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 is supported for multimedia applications • Eight general purpose registers (GPR) • 18 interrupt sources with 2-level priority Memory • 32K-word program memory • 2K-word data RAM • 096/128/192/256/384/512K-word data ROM Peripherals • Real Time Clock (RTC) with wake-up function • Four 8-bit timers, two general purpose timers, two multiple-function timers • 8-bit Watchdog Timer (WDT) with general purpose timer capability • 24 GPIO Product Specification (V1.7) 12.1.2009 (This specification is subject to change without further notice) •1 eAMS Series 16 Bits DSP Sound Processor 3 Block Diagram Figure 3-1 ELAN eAMS System Block Diagram 2• Product Specification (V1.7) 12.1.2009 (This specification is subject to change without further notice) eAMS Series 16 Bits DSP Sound Processor 4 Selection Table The ELAN eAMS 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.
