19 ns Instruction Cycle Time @ 3.3 Volts, 52 MIPS Sustained Performance
Single-Cycle Instruction Execution Set Extensions
80K Bytes of On-Chip RAM, Configured as 16K Words Program Memory RAM and 16K Words Data Memory RAM
Dual Purpose Program Memory for InstructionÊ and Data Storage

Single-Cycle Instruction Execution
16-Bit Internal DMA Port for High Speed Access to On-Chip Memory (Mode Selectable)
4 MByte Memory Interface for Storage of Data Tables and Program Overlays (Mode Selectable)
8-Bit DMA to Byte Memory for Transparent Program and Data Memory Transfers (Mode Selectable)

The ADSP-2185L is a single-chip, 3.3V microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.

The ADSP-2185L integrates 80K bytes of on-chip memory configured as 16K words (24-bit) of program RAM and 16K words (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-2185L is available in 100-pin LQFP package.

In addition, the ADSP-2185L supports new instructions, which include bit manipulations- bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking, for increased flexibility.
