DSP56004ROM
Motorola designed the Symphony™ family of high-performance, programmable Digital Signal
Processors (DSPs) to support a variety of digital audio applications, including Dolby ProLogic,
ATRAC, and Lucasfilm Home THX processing. Software for these applications is licensed by
Motorola for integration into products like audio/video receivers, televisions, and automotive
sound systems with such user-developed features as digital equalization and sound field
processing. The DSP56004 is an MPU-style general purpose DSP, composed of an efficient 24-bit
Digital Signal Processor core, program and data memories, various peripherals optimized for
audio, and support circuitry. As illustrated in Figure 1, the DSP56000 core family compatible
DSP is fed by program memory, two independent data RAMs and two data ROMs, a Serial
Audio Interface (SAI), Serial Host Interface (SHI), External Memory Interface (EMI), dedicated
I/O lines, on-chip Phase Lock Loop (PLL), and On-Chip Emulation (OnCE) port.

Data Sheet Conventions
This data sheet uses the following conventions:
OVERBAR
“asserted”
“deasserted”
Examples:
Used to indicate a signal that is active when pulled low (For example, the RESET
pin is active when low.)
Means that a high true (active high) signal is high or that a low true (active low)
signal is low
Means that a high true (active high) signal is low or that a low true (active low)
signal is high
