HYBRID MCU/DSP

56853

120 MIPS Hybrid Processor

TARGET APPLICATIONS

BENEFITS

• DTAD

• 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

• Feature phone

• Voice recognition and command

• Embedded modem/data pump

• Voice processing

• Supports multiple processor

connections

• Serial peripheral interface with master

and slave mode supporting connection

to other processors or serial memory

devices

• Low bit rate audio processing

• Multi-processor Telephony

Systems

• LCD and keypad support

• General purpose devices

• Automotive hands-free

• 16-bit quad timer module (with four

external pins) that allows

capture/compare functionality, and can

be cascaded

• External memory expansion up to 2M

words program memory or up to 8M

words data memory increases

capabilities of device for larger

algorithms

• 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 56853’s memory and peripheral set make it

ideal for a variety of applications, with a total of

four external timer outputs for the quad timer, an

additional SCI/UART, an 8-bit host interface and

6-channel direct memory access (DMA). Also, the

56853 offers an enhanced synchronous serial

interface (ESSI), with enhanced networking mode

and audio capabilities. The external memory

expansion is also increased for an additional 2 MB

of data addressing space. The 56853 also includes a

Time of Day module for applications, requiring clock

features. With the host interface and serial

peripherals, multiple 56853 devices can be designed

into a system to interface gluelessly with other

Motorola processors, such as the MPC8xx and

ColdFire processors, adding such DSP functionality

as voice processing to network applications.

The 56853 is available in a 128-pin LQFP package

and is an ideal stand-alone processor for client-side

telecom/datacom applications, requiring only a

few channels.
