.. Speech And Music Processor Data sheet Features Advanced, Integrated Speech Synthesizer for High-Quality Sound Operates up to 12.32 MHz (Performs up to 12 MIPS) Slave Mode Enables Hours of Speech Using an External Processor and Memory Master Mode Allows 6.8 Minutes of Speech Onboard Supports High-Quality Synthesis Algorithms such as MX, CX, Simple CX, LX, ADPCM, and Polyphonic Music Simultaneous Speech Plus Music Capabilities Very Low-Power Operation, Ideal for Hand-Held Devices Low-Voltage Operation, Sustainable by Three (3) Batteries Reduced Power Standby Modes, Less Than 10 µA in Deep-Sleep Mode 16 General-Purpose I/O Pins (in Master Mode) or 4 General-Purpose I/O Pins (in Slave Mode) Resistor-Trimmed Oscillator or 32.768-k Hz Crystal Reference Oscillator Slave Interface Logic Contains 64K Bytes Words Onboard ROM (2K Words Reserved) 640-Word RAM Direct Speaker Drive, 32 Ω (PDM) One-Bit parator With Edge Detection Interrupt Service Serial Scan Port for In-Circuit Emulation, Monitor, and Test Available in Die Form or 64-Pin LQFP Package Description The SC-604 is a low-cost, mixed-signal processor that bines a speech synthesizer with a dedicated slave interface logic, generalpurpose I/O, onboard ROM, and direct speakerdrive in a single package. The putational unit uses a powerful new DSP that gives the SC604 unprecedented speed and putational flexibility pared with previous devices of its type. The SC-604 supports a variety of speech and audio coding algorithms, providing a range of options with respect to speech duration and sound quality.
