ADSP-2188MBCA-266

Digital Signal Processor Dsp Overview

The ADSP-2188MBCA-266 is a fixed-point digital signal processor from the ADSP-2100 family, fabricated in a high-speed CMOS process. It features a 13.3 ns instruction cycle time and sustains 75 MIPS performance. The device integrates 256K bytes of on-chip memory, configured as 48K words (24-bit) of program RAM and 56K words (16-bit) of data RAM. It operates with a 2.75 V internal core voltage and supports 2.75 V or 3.3 V I/O levels. The processor utilizes a three-bus architecture allowing dual operand fetches and single-cycle context switching.
