External Memory Expansion
• Data memory expansion to two 256 K × 24-bit word memory spaces using the standard external
address lines
• Program memory expansion to one 256 K × 24-bit words memory space using the standard external
address lines
• External memory expansion port
• Chip Select Logic for glueless interface to static random access memory (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 DSP56309 is available in a 144-pin TQFP package or a 196-pin MAP-BGA package.
Target Applications
The DSP56309 is intended for applications benefiting from a large amount of internal memory, such as
wireless infrastructure applications.
