Texas Instruments MSP50C604
The MSP50C604 is a low-cost, mixed-signal processor that combines a speech synthesizer with a dedicated slave interface logic, general-purpose I/O, onboard ROM, and direct speaker-drive in a single package. The computational unit uses a powerful new DSP that gives the MSP50C604 unprecedented speed and computational flexibility compared with previous devices of its type. The MSP50C604 supports a variety of speech and audio coding algorithms, providing a range of options with respect to speech duration and sound quality.MSP50C604 MIXED-SIGNAL PROCESSOR D Advanced, Integrated Speech Synthesizer for High-Quality Sound D Operates up to 12.32 MHz (Performs up to 12 MIPS) D Slave Mode Enables Hours of Speech Using an External Processor and Memory D Master Mode Allows 6.8 Mins of Speech Onboard D Supports High-Quality Synthesis Algorithms such as MELP, CELP, LPC, ADPCM, and Polyphonic Music D Simultaneous Speech Plus Music Capabilities D Very Low-Power Operation, Ideal for Hand-Held Devices D Low-Voltage Operation, Sustainable by Three (3) Batteries D Reduced Power Standby Modes, Less Than 10 µA in Deep-Sleep Mode SPSS028B – MAY 2000 – REVISED FEBRUARY 2001 D 16 General-Purpose I/O Pins (in Master Mode) or 4 General-Purpose I/O Pins (in Slave Mode) D Resistor-Trimmed Oscillator or 32.768-kHz Crystal Reference Oscillator D Slave Interface Logic D Contains 64K Bytes-Words Onboard ROM (2K Words Reserved) D 640-Word RAM D Direct Speaker Drive (32 Ω) (PDM) D One-Bit Comparator With Edge Detection Interrupt Servi...
