SM320C32PCMM50EP

The SM320C32PCMM50EP is a 32-bit floating-point digital signal processor (DSP) from Texas Instruments, part of the C3x family, offered in an Enhanced Product (EP) grade for high-reliability embedded computing. Operating at 50 MHz, it integrates a high-performance floating-point arithmetic unit capable of delivering 50 MFLOPS and 25 MIPS, supported by an external memory interface with glueless connection to SRAM and peripherals. The architecture includes a 24-bit address and 32-bit data bus, two 32-bit timers, and a high-speed serial port, all housed in a 144-lead plastic quad flat pack (PQFP) package. The EP qualification indicates a controlled baseline, extended temperature range, and enhanced manufacturing flow intended for mission-critical environments.

Typical applications center on computationally intensive signal processing within aerospace, defense, and industrial automation systems—such as radar and sonar processing, flight control computers, avionics, vibration analysis, and high-speed motor control. The floating-point architecture simplifies algorithm implementation for fast Fourier transforms, digital filtering, and matrix arithmetic, reducing development effort in systems where dynamic range and precision are paramount. From a procurement perspective, the EP suffix denotes a product built under Texas Instruments’ Enhanced Product lifecycle management, offering extended availability and change control suitable for long-term defense and industrial programs. As the C3x family is a mature platform, design and supply-chain teams should incorporate obsolescence risk planning; the EP designation helps mitigate this by locking the baseline and providing extended support, making the device a reliable choice for sustaining legacy systems and next-generation high-reliability upgrades alike.
