DSP56303

Target Applications

MOTOROLA DSP56303P/D 3

• Off-chip memory expansion

– Data memory expansion to two 256 K x 24-bit word memory spaces

– Program memory expansion to one 256 K x 24-bit word memory space

– External memory expansion port

– Chip select logic requires no additional circuitry to interface to SRAMs and

SSRAMs

– On-chip DRAM controller requires no additional circuitry to interface to DRAMs

• On-chip peripherals

– 8-bit parallel Host Interface (HI08), ISA-compatible bus interface, providing a

cost-effective solution for applications not requiring the PCI bus

– Two Enhanced Synchronous Serial Interfaces (ESSI)

– Serial Communications Interface (SCI) with baud rate generator

– Triple timer module

– Up to thirty-four programmable General Purpose I/O pins (GPIO), depending on

which peripherals are enabled

• Reduced power dissipation

– Very low power CMOS design

– Wait and Stop low power standby modes

– Fully-static logic, operation frequency down to DC

– Optimized power management circuitry

TARGET APPLICATIONS

The DSP56303 is intended for use in telecommunication applications, such as multi-line

voice/data/fax processing, videoconferencing, audio applications, control, and general

digital signal processing.
