devices.
Low-voltage operation, sustainable by three
batteries.
Reduced power stand-by modes, less than 10
μ
A 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 (key-
scan).
Direct speaker driver, 32
(
PDM).
One-bit
comparator
interrupt service.
Resistor-trimmed oscillator or 32.768 kHz
crystal reference oscillator.
Serial scan port for in-circuit emulation and
diagnostics.

Description
The SC-605 is a low-cost, mixed-signal
processor that combines a speech synthesizer,
general-purpose I/O, onboard ROM, and direct
speaker drive in a 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.
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.
