Speech And Music Processor

Data sheet

Features

ꢀ Advanced, integrated speech synthesizer for

high-quality sound.

ꢀ 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 (key-

scan).

ꢀ 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).

ꢀ Direct speaker driver, 32 Ω (PDM).

ꢀ One-bit

comparator with edge-detection

ꢀ Supports high-quality synthesis algorithms

Such as: MX, CX, Simple CX, LX, ADPCM, and

Polyphonic Music.

interrupt service.

ꢀ Resistor-trimmed oscillator or 32.768 kHz

crystal reference oscillator.

ꢀ Simultaneous speech plus music capabilities.

ꢀ Very low-power operation, ideal for hand-held

devices.

ꢀ Serial scan port for in-circuit emulation and

diagnostics.

ꢀ The SC-605 is sold in die form or 100-pin LQFP

package.

ꢀ Low-voltage operation, sustainable by three

batteries.

ꢀ An emulator device is available in a ceramic

package for development (SC-614-P).

ꢀ Reduced power stand-by modes, less than 10

µA in Deep-Sleep mode.

single package. The

computational unit utilizes a powerful new DSP

which gives the SC-605 unprecedented speed

and computational flexibility compared with

previous devices of its type. The SC-605

supports a variety of speech and audio coding

algorithms, providing a range of options with

respect to speech duration and sound quality.

COMPARATOR

The device consists of a micro-DSP core,

embedded program, and data memory, and a self-contained clock generation system. General-purpose

periphery is comprised of 32 bits of partially configurable I/O. The core processor is a general-purpose 16-bit

microcontroller with DSP capability. The basic core block includes computational unit (CU), data address unit,

program address unit, two timers, eight level interrupt processor, and several system and control registers. The

core processor gives the SC-605 break-point capability in emulation.

The processor is Harvard type for efficient DSP algorithm execution. It requires separate program and data

memory blocks to permit simultaneous access. The ROM has a protection scheme to prevent third-party

pirating. It is configured in 32K 17-bit words.

The total ROM space is divided into three areas:

1) The lower 2K words are reserved by Sensory, Inc. for the purposes of a built-in self-test

2) The upper 30K words are for user program/data

3) Additional 1.83 Mb data ROM provides data for up to 37 minutes of speech.
