Advance Information
16-BIT DIGITAL SIGNAL PROCESSOR
P R E L I M I N A R Y The general-purpose, programmable DSP56167 is an enhanced version of the DSP56166 with
added features. Designed primarily for speech coding and digital communications, the
DSP56167 has a built-in Σ∆ codec and Phase Lock Loop (PLL). This MPU-style DSP also contains
memories and digital peripherals that provide a cost effective, high performance solution to
many DSP applications. On-Chip Emulation (OnCE) circuitry provides convenient and
inexpensive debug facilities normally available only through expensive external hardware. This
RAM-based DSP contains a 2 K × 16 Program RAM and a 4 K × 16 data RAM. The Central
Processing Unit (CPU) consists of three execution units operating in parallel allowing up to six
operations to occur in an instruction cycle. This parallelism greatly increases the effective
processing speed of the DSP56167. The MPU-style programming model and instruction set
allow straightforward generation of efficient, compact code. The DSP56167 is a member of
Motorola’s DSP56100 family of 16-bit Digital Signal Processors (DSPs).

Data Sheet Conventions
This data sheet uses the following conventions:
OVERBAR
“asserted”
“deasserted”
Examples:
Used to indicate a signal that is active when pulled low; for example, the RESET
pin is active when low
Means that a high true (active high) signal is high or that a low true (active low)
signal is low
Means that a high true (active high) signal is low or that a low true (active low)
signal is high
