SC-601

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)

Single chip solution for up to 24 Minutes of

speech (using 1.57 Mb of onboard program +

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 handheld

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 resistor and a dedicated interrupt (Key-

Scan)

Direct Speaker Driver, 32Ω (PDM)

One-bit comparator with edge-detection

interrupt service

Resistor-trimmed oscillator or 32.768kHz crystal

reference oscillator

Serial scan port for in-circuit emulation and

diagnostics

The SC-601 is sold in die form or 100-pin LQFP

package.

An emulator device is available in a ceramic

package for development (SC-614-P).

Description

The SC-601 is a low-cost, mixed-signal

processor that combines a speech synthesizer,

general-I/O, onboard ROM, and direct speaker

drive in a single package. The computational

unit utilizes a powerful DSP which gives the SC-

601 unprecedented speed and computational

flexibility compared with previous devices of its

type. The SC-601 supports a variety of speech

and audio coding algorithms, providing range of

options for speech duration and sound quality.

The device consists of a micro-DSP core,

embedded program, and data memory, and a

self-contained 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 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-601 break-capability in emulation.

The processor is Harvard type for efficient DSP algorithm execution. It requires separate program and 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 a built-in self-test

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

3. An additional 1 Mb data ROM provides for up to 24 minutes of speech.
