• IP phones

• Client-side IP applications

• IADs

• Voice and audio processing

• Voice recognition and command

• General purpose devices

• Easy to program with flexible

application development tools

• Flexible 6-Channel Direct Memory

Access (DMA) allows both internal and

external memory transfers with almost

no CPU interruption

• Supports multiple processor

connections

• Serial peripheral interface with master

and slave mode supporting connection

to other processors or serial memory

devices

• 16-bit quad timer module (with four

external pins) that allows

capture/compare functionality, and can

be cascaded

• Two enhanced synchronous serial

interfaces with three transmitters per

module provide support for 5.1 channel

surround sound for audio applications

• Quad timer module can also be used for

simple digital-to-analog conversion

functionality

• Enhanced synchronous serial interface

with enhanced network and audio modes

• Time of Day for applications requiring

clock display

The 56858 offers a rich feature set and on-chip

memory interface. It includes external memory

expansion with up to 2M words of program or up to

8M words of data addressing space, and is

available in both 144 LQFP and 144 MBGA

56858 16-BIT DIGITAL SIGNAL PROCESSORS

• 120 MIPS at 120MHz

• Serial Peripheral Interface (SPI)

packages. The 56858 includes 40K words of on-chip

program SRAM and 24K words of on-chip data

SRAM. With two enhanced serial synchronous serial

interfaces (ESSIs), this device can provide outputs

for 5.1-channel surround sound. The 56858 is ideal

for client-side telecom/datacom applications

requiring up to four channels, including IP phones.

This device can be designed into multi-processor

systems to provide internet audio and speech

processing functionalities and can provide a

stand-alone device for internet audio.
