Frequently Asked Questions
What is the CPU performance and RAM capacity of the TMS320C28343ZAYT?
The TMS320C28343ZAYT features a 32-bit C28x CPU core running at up to 150 MHz for 200 MIPS of performance, paired with a hardware floating-point unit. It integrates 260KB of on-chip SRAM, enabling large data buffers and dual-mapped program and data memory access typical of DSP applications.
Does the TMS320C28343ZAYT have an external memory interface?
Yes, the TMS320C28343ZAYT includes an External Memory Interface (EMIF) with a 20-bit address bus, allowing connection of external SRAM, Flash, or other memory devices. This makes it suitable for applications requiring more program or data memory than available on-chip, such as large look-up table storage or real-time data logging.
What is the supply voltage and operating temperature range of the TMS320C28343ZAYT?
The TMS320C28343ZAYT operates from a 3.3V supply (as noted in its specification) and supports an operating temperature range of -40 to 105 degrees C. This industrial temperature range makes it suitable for harsh environments such as motor drives, solar inverters, and factory automation equipment.
What package does the TMS320C28343ZAYT use?
The TMS320C28343ZAYT is housed in a 179-ball NFBGA (Non-leaded Fine-pitch Ball Grid Array) package with the suffix ZAYT. The BGA package provides a large number of I/O connections in a compact area with excellent thermal and electrical performance, requiring BGA-capable PCB design with appropriate via-in-pad or via-dog-bone escape routing.
What applications is the TMS320C28343ZAYT best suited for?
The TMS320C28343ZAYT excels in real-time digital control applications such as multi-axis AC motor drives, high-frequency DC/DC converters, UPS inverters, and solar power conditioning systems. Its 200 MIPS FPU-equipped core handles computationally intensive control algorithms like field-oriented control (FOC) and model-predictive control (MPC) with deterministic loop times well under 10 microseconds.
