DSP56362 Advance Information

MOTOROLA

Overview

Features

•

End-of-block-transfer interrupts

•

Triggering from interrupt lines and all peripherals

–

Phase-locked loop (PLL)

•

Software programmable PLL-based frequency synthesizer for the core clock

•

Allows change of low-power divide factor (DF) without loss of lock

•

Output clock with skew elimination

–

Hardware debugging support

•

On-Chip Emulation (OnCE‘) module

•

Joint Action Test Group (JTAG) test access port (TAP)

•

Address trace mode reflects internal program RAM accesses at the external port

•

On-Chip Memories

–

Modified Harvard architecture allows simultaneous access to program and data memories

–

30720 x 24-bit on-chip program ROM1 (disabled in 16-bit compatibility mode)

–

6144 x 24-bit on-chip X-data ROM1

–

6144 x 24-bit on-chip Y-data ROM1

–

Program RAM, instruction cache, X data RAM, and Y data RAM sizes are programmable

–

192 x 24-bit bootstrap ROM (disabled in sixteen-bit compatibility mode)

•

Off-Chip Memory Expansion

–

Data memory expansion to 256K x 24-bit word memory for P, X, and Y memory using SRAM.

–

Data memory expansion to 16M x 24-bit word memory for P, X, and Y memory using DRAM.

–

External memory expansion port( twenty-four data pins for high speed external memory

access allowing for a large number of external accesses per sample)

–

Chip select logic for glueless interface to SRAMs

–

On-chip DRAM controller for glueless interface to DRAMs

•

Peripheral and Support Circuits

–

Enhanced serial audio interface (ESAI) includes:

•

Six serial data lines, 4 selectable as receive or transmit and 2 transmit only.

•

Master or slave capability

•I2S, Sony, AC97, and other audio protocol implementations

1.These ROMs may be factory programmed with data or programs provided by the application developer.
