4 / 49 page  GPCE4XXXX © Generalplus Technology Inc. Proprietary & Confidential 4 Jun. 26, 2017 Version: 1.1 16-BIT SOUND CONTROLLER 1 GENERAL DESCRIPTION GPCE4xxxx, a 16-bit architecture sound controller with USB interface, features the newest 16-bit microprocessor, ’nSP2.0™ (pronounced as micro-n-SP 2.0). This high processing speed assures the ’nSP2.0™ is capable of handling complex digital signal processes easily and rapidly. Therefore, GPCE4xxxx is applicable for the areas of digital sound process and voice recognition. The operating voltage of 2.4V through 5.5V and speed up to 48MHz yield the GPCE4xxxx to be easily used in varieties of applications. The memory capacity includes ROM (or OTP) plus a 4K-word working SRAM and 2K-word Cache RAM (also can be working RAM). Other features including 48 programmable multi-functional I/Os, five 16-bit timers/counters, 32768Hz Real Time Clock, Low Voltage Reset/Detection, eight channels 12-bit ADC (one channel built-in MIC amplifier with auto gain controller), capacitive touch sensor, one SPI flash controller, one 16-bit DAC with push-pull amplifier and many others. 2 FEATURES 16-bit ’nSP2.0™ microprocessor CPU Clock: max. 48MHz Operating Voltage: 2.4V - 5.5V Power regulator built-in with input voltage: 2.4~5.5V, output voltage: 2.4~3.3V IO PortA & B & C Operating Voltage: 2.4V - 5.5V Fast speed OTP or ROM (by body) 4K-word working SRAM 2K-word cache SRAM (also can be released to working-RAM) Total 384-byte buffer RAM Software-based audio processing Two sets of 14-bit software channel with noise filter, mixer and scalar to play high quality sound Standby mode for power saving Total five 16-bit timers, including three general-purpose 16-bit timers/counters, two touch-sensing timers (also can released for general-purpose use). One 14-bit DAC with push-pull amplifier. Supports cascade mode as well as stereo mode 48 general I/Os (bit programmable) Key wakeup function (IOA0 - 15, IOB0-15, IOC0-15) Capacitor touch-sensing hardware for 48 I/O PLL feature for system clock 32768Hz Real Time Clock (RTC), crystal or internal resistor oscillator selected. Eight channels 12-bit AD converter, Built-in microphone amplifier and AGC or PGA function selected Low voltage reset and low voltage detection Watchdog Enable (option) Two SPI serial interface I/Os. One is SPI flash controller which supports one-I/O, two-I/O, four-I/O modes and support auto read/program mode. The other is normal SPI interface. Supports USB 2.0 full speed (12MHz) compliant device with built-in transceiver (by body option) 3 APPLICATION FIELD Voice Recognition Products Intelligent Interactive Talking Toys Advanced Educational Toys Kids Learning Products Kids Storybook General Speech Synthesizer Long Duration Audio Products Recording / Playback Products |
