External Memory Expansion
• Data memory expansion to two 16 M × 24-bit word memory spaces in 24-Bit mode or two 64 K
× 16-bit memory spaces in 16-Bit Compatibility mode
• Program memory expansion to one 16 M × 24-bit words memory space in 24-Bit mode or 64 K ×
16-bit in 16-Bit Compatibility mode
• External memory expansion port
• Chip Select Logic for glueless interface to SRAMs
• Internal DRAM Controller for glueless interface to dynamic random access memory (DRAMs)
Reduced Power Dissipation
• Very low-power CMOS design
• Wait and Stop low-power standby modes
• Fully static design specified to operate down to 0 Hz (dc)
• Optimized power management circuitry (instruction-dependent, peripheral-dependent, and
mode-dependent)
Packaging
The DSP56301 is available in a 208-pin thin quad flat pack (TQFP) or a 252-pin molded array
process-ball grid array (MAP-BGA) package. Both packages are available in lead-bearing and
lead-free versions.
Target Applications
Examples of target applications include:
• Wireless and wireline infrastructure applications
• Multi-channel wireless local loop systems
• DSP resource boards
• High-speed modem banks
• Packet telephony
