DSP56321VF275

The Freescale (now NXP Semiconductors) DSP56321VF275 is a high-performance 24-bit digital signal processor from the DSP56300 family. It is designed for applications requiring significant processing power, such as networking, security encryption, and home entertainment.

This processor features a single-clock-cycle-per-instruction engine, a barrel shifter, 24-bit addressing, an instruction cache, and a DMA controller. It achieves a performance of 275 million multiply-accumulates per second (MMACS), which can be boosted to 550 MMACS when the EFCOP is in use. The device operates with an internal 275 MHz clock, a 1.6-volt core, and independent 3.3-volt input/output (I/O) power.

The DSP56321VF275 is intended for applications that require a large amount of internal memory, including networking and wireless infrastructure. The onboard EFCOP is capable of accelerating general filtering applications like echo cancellation, correlation, and convolution-based algorithms. It is supplied in a 196-MAPBGA (15x15) package and supports surface mount.

Key specifications include a 275 MHz clock rate, 1.6V core voltage, 3.3V I/O voltage, and an operating temperature range of -40°C to 100°C (TJ). It offers 576kB of on-chip memory and various interfaces including Host Interface, SSI, and SCI.
