FEATURES
Advanced, integrated speech synthesizer for high-quality sound. Operates up to 12.32 MHz (performs up to 12 MIPS). Single chip solution for up to 37 minutes of speech (using 2.36 Mb of onboard program plus data ROM). 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 batteries. Reduced power stand-by modes, less than 10 µA in Deep-Sleep mode. 640-word RAM. 32 I/O pins consisting of: 24 general-purpose bit configurable I/O, 8 inputs with programmable pullup resistors and a dedicated interrupt (keyscan). Direct speaker driver, 32 Ω (PDM). One-bit comparator with edge-detection interrupt service. Resistor-trimmed oscillator or 32.768 kHz crystal reference oscillator. Serial scan port for in-circuit emulation and diagnostics. An emulator device is available in a ceramic package for development (SC-614-P).
