Frequently Asked Questions
What processing speed does the TMS320C28343ZFEQ achieve, and how does floating-point support help in motor control?
The TMS320C28343ZFEQ operates at up to 300 MHz, delivering 300 MFLOPS of IEEE 754 single-precision floating-point performance. Native hardware floating-point eliminates the need for fixed-point scaling in FOC and SVM algorithms, reducing code complexity and cutting execution time per control iteration by 30% to 50% compared to fixed-point C28x variants.
What supply voltage does the TMS320C28343ZFEQ require, and can it interface directly with 3.3 V peripherals?
The TMS320C28343ZFEQ operates at a 3.3 V core and I/O supply, allowing direct interface with 3.3 V logic peripherals such as gate drivers, encoders, and communication transceivers without level-shifting. A separate 1.8 V internal core regulator is typically required for the CPU core, but GPIO and peripheral pins are 3.3 V tolerant, simplifying board design.
How large is the address space on the TMS320C28343ZFEQ, and what memory configurations does it support?
The TMS320C28343ZFEQ features a 22-bit address bus providing a 4 MB total addressable space, which accommodates on-chip Flash, SARAM, and external memory expansion. Its large address space supports demanding real-time operating systems and complex firmware images in multi-phase converter controllers with extensive fault-logging and communication stack requirements.
Does the TMS320C28343ZFEQ include boundary scan, and how does that simplify board-level testing in production?
Yes, the TMS320C28343ZFEQ supports JTAG boundary scan per IEEE 1149.1, allowing automated in-circuit testing of all device I/O pins without physical test probes. This reduces PCB test fixture complexity and enables functional testing of interconnects at production throughputs above 1000 boards per hour in automated test equipment setups for industrial drive and inverter assemblies.
