Description

Electronic Component Model: XC56301PW80D

Product Category: IC Chips

The Motorola DSP56307 is a 24-BIT digital signal processor that belongs to the DSP56300 family of programmable DSPs. It is specifically designed to support wireless infrastructure applications, particularly in general filtering operations. With its on-chip enhanced filter coprocessor (EFCOP), the DSP56307 is capable of processing filter algorithms in parallel with core operation, resulting in improved overall DSP performance and efficiency. Equipped with a high-performance, single-clock-cycle-per-instruction engine (code-compatible with Motorolas popular DSP56000 core family), a barrel shifter, 24-bit addressing, an instruction cache, and a direct memory access controller, the DSP56307 offers top-notch performance of 100 million instructions per second (MIPS) using an internal 100 MHz clock with a 2.5V core and independent 3.3V input/output power.
