1.2 DSP56852 Description

The DSP56852 is a member of the DSP56800E core-based family of Digital Signal Processors (DSPs). On

a single chip it combines the processing power of a DSP and the functionality of a microcontroller with a

flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost,

configuration flexibility, and compact program code, the DSP56852 is well-suited for many applications.

The DSP56852 includes many peripherals especially useful for low-end Internet appliance applications

and low-end client applications such as telephony; portable devices; Internet audio; and point-of-sale

systems such as noise suppression; ID tag readers; sonic/subsonic detectors; security access devices;

remote metering; and sonic alarms.

The DSP56800E core is based on a Harvard-style architecture consisting of three execution units operating

in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming

model and optimized instruction set allow straightforward generation of efficient, compact code for both

DSP and MCU applications. The instruction set is also highly efficient for C-Compilers, enabling rapid

development of optimized control applications.

The DSP56852 supports program execution from either internal or external memories. Two data operands

can be accessed from the on-chip Data RAM per instruction cycle. The DSP56852 also provides two

external dedicated interrupt lines, and up to 11 General Purpose Input/Output (GPIO) lines, depending on

peripheral configuration.

The DSP56852 DSP controller includes 6K words of Program RAM, 4K words of Data RAM and 1K of

Boot RAM. It also supports program execution from external memory.

This DSP controller also provides a full set of standard programmable peripherals that include one improved

Synchronous Serial Interface (SSI) or one Serial Peripheral Interface (SPI), one Serial Communications

Interface (SCI), and one Quad Timer. The SSI, SPI, SCI I/O and three chip selects can be used as General

Purpose Input/Outputs when its primary function is not required. The SSI and SPI share I/O, so, at most,

one of these two peripherals can be in use at any time.

1.3 State of the Art Development Environment

• Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-

use component-based software application creation with an expert knowledge system.

• The Code Warrior Integrated Development Environment is a sophisticated tool for code navigation,

compiling, and debugging. A complete set of evaluation modules (EVMs) and development system

cards will support concurrent engineering. Together, PE, Code Warrior and EVMs create a

complete, scalable tools solution for easy, fast, and efficient development.
