TMS320C31PQA40 Description

Short technical summary and product information.

The Texas Instruments TMS320C31PQA40 is a high-performance 32-bit floating-point digital signal processor (DSP) from the TMS320C3x generation. Fabricated using 0.6 μm EPIC CMOS technology, this DSP offers a 40MHz clock rate, enabling 220 MOPS, 40 MFLOPS, and 20 MIPS performance.

 

Key features include a 32-bit instruction word, 24-bit addresses, and 8.25kB of on-chip dual-access RAM. It supports parallel arithmetic/logic unit (ALU) and multiplier operations in a single cycle. On-chip peripherals include a serial port, two 32-bit timers, and a single-channel DMA coprocessor for concurrent I/O and CPU operation.

 

The TMS320C31PQA40 is housed in a 132-pin Plastic Quad Flat Package (PQ Suffix) and is designed for surface mounting. It operates with a core and I/O voltage of 5V and has an operating temperature range of -40°C to 125°C (TC).

 

This DSP is suitable for demanding real-time applications requiring high-speed arithmetic and parallel processing capabilities, such as signal processing, communications, and control systems.
