Product details
Overview
TMS320F28335ZJZA from Texas Instruments is a high-performance 32-bit real-time microcontroller featuring a 150-MHz C28x CPU with IEEE 754 single-precision FPU, 256K × 16 flash, 34K × 16 SARAM, and 12-bit 16-channel ADC with 80-ns conversion time. It delivers deterministic control for industrial motor drives, solar inverters, and EV traction systems.
For engineers reviewing the TMS320F28335ZJZA datasheet, TMS320F28335ZJZA pinout, TMS320F28335ZJZA application, or TMS320F28335ZJZA equivalent, key selection factors include FPU-enabled closed-loop computation, 18 ePWM/6 HRPWM outputs with 150-ps MEP resolution, dual CAN interfaces, and BGA-176 packaging for thermal and layout stability in high-power control designs.
Technical Context
The TMS320F28335ZJZA implements a Harvard bus architecture with unified memory programming model, enabling efficient C/C++ execution and fast interrupt response. Its six-channel DMA controller offloads ADC, ePWM, McBSP, and XINTF data transfers, reducing CPU overhead in real-time servo and inverter control loops.
It integrates a 12.5-MSPS 12-bit ADC with dual sample-and-hold and two 8-channel multiplexers, supporting simultaneous sampling across multiple current/voltage sensing paths. The on-chip oscillator, PLL, watchdog timer, and PIE block managing 58 peripheral interrupts provide robust system-level timing and fault handling for safety-critical power electronics.
