Description
• 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) up to 100
MHz operating frequency
• 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)
• Molded array plastic-ball grid array (MAP-BGA) package in lead-free or lead-bearing versions.
Target Applications
DSP56311 applications require high performance, low power, small packaging, and a large amount of internal
memory. The EFCOP can accelerate general filtering applications. Examples include:
• Wireless and wireline infrastructure applications
• Multi-channel wireless local loop systems
• DSP resource boards
• High-speed modem banks
• IP telephony
