Advance Information
INTEGRATED CELLULAR BASEBAND PROCESSOR
Motorola designed the ROM-based DSP56652 to support the rigorous demands of the cellular
subscriber market. The high level of on-chip integration in the DSP56652 minimizes application
system design complexity and component count, resulting in very compact implementations.
This integration also yields very low-power consumption and cost-effective system
performance. The DSP56652 chip combines the power of MotorolaÕs 32-bit M¥CORE (TM)
MicroRISC Engine (MCU) and the DSP56600 digital signal processor (DSP) core with on-chip
memory, protocol timer, and custom peripherals to provide a single-chip cellular base-band
processor. Figure 1 shows the basic block diagram of the DSP56652.

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
