- GENERAL DESCRIPTION GPDS301A, an advanced speech decoder, is designed to co-work with a host co ntroller for spe ech/melody dec oder. The host controller is able to issue co mmands and dat a to GPDS301A as well as receivin g st atus from GPDS301A thro ugh Gene ralplus Serial Interface IO (SIO). GPDS301A support s S200 (1. 4Kbps, 2.8Kbps, 3.36K bps), S480 (4.8 Kbps), 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 easil y get high qualit y speech sound fr om 12-bit PWM without an y amp lifier to drive a speaker. 2. FEATURES Operating voltage : 2.4V ~ 3.6V A pair of PWM output with 12-bit resolution Built in Generalplus Serial Interface (SIO) R oscillator Algorithms: − S200 (1.4K, 2.8K, 3.36K bps), supports speed control and pitch control. − S480/S720 (4.8K/7.2K bps) − A1600 (10K, 12K, 14K, 16K, 20K, 24K bps) − MS01(4 channel FM, 2 channel ADPCM) 3.
