1、SPCE061A 32K x 16 SOUND CONTROLLER1. GENERAL DESCRIPTIONThe SPCE061A, a 16-bit architecture product, carries the newest 16-bit microprocessor, ynSPTM (pronounced as micro-n-SP), developed by Sunplus Technology. This high processing speed assures the gnSP is capable of handling complex digital signal
2、 processes easily and rapidly. Therefore, the SPCE061A is applicable to the areas of digital sound process and voice recognition. The operating voltage of 3.0V through 3.6V and speed of 0.32MHz through 49.152MHz yield the SPCE061A to be easily used in varieties of applications. The memory capacity i
3、ncludes 32K-word flash memory plus a 2K-word working SRAM. Other features include 32 programmable multi-functional I/Os, two 16-bit timers/counters, 32768Hz Real Time Clock, Low Voltage Reset/Detection, eight channels 10-bit ADC (one channel built-in MIC amplifier with auto gain controller), 10-bit
