GPDS301A中文资料16 bit DSP Sound Processor数据手册Generalplus规格书

描述 Description

GPDS301A, an advanced speech decoder, is designed to co-work with a host controller for speech/melody decoder. The host controller is able to issue commands and data to GPDS301A as well as receiving status from GPDS301A through Generalplus Serial Interface IO (SIO). GPDS301A supports S200 (1.4Kbps, 2.8Kbps, 3.36Kbps), S480 (4.8Kbps), S720 (7.2Kbps), A1600 (10Kbps~ 24Kbps), MS01 (4-channel FM, 2 channel ADPCM), not only does the host store data efficiently, but it also retains a good resolution to the original sound. User can easily get high quality speech sound from 12-bit PWM without any amplifier to drive a speaker.
