Product details
Overview
TMS320F28334PTPQ from Texas Instruments is a high-performance 32-bit real-time microcontroller with IEEE 754 single-precision FPU, 150-MHz CPU clock, 128K × 16 flash, 34K × 16 SARAM, and 12-bit 16-channel ADC operating at 12.5 MSPS. It supports automotive-grade operation (–40°C to 125°C) and integrates dual eCAN, three SCI, two McBSP, SPI, I²C, six ePWM modules, and HRPWM with 150-ps MEP resolution - deployed in motor control and power conversion systems.
For engineers reviewing the TMS320F28334PTPQ datasheet, TMS320F28334PTPQ pinout, TMS320F28334PTPQ application, or TMS320F28334PTPQ equivalent, key selection criteria include FPU-enabled C28x core performance, AEC-Q100 qualified thermal rating, HLQFP-176 package compatibility, and peripheral feature parity with F28335/F28332 for migration paths in industrial and automotive control designs.
Technical Context
The TMS320F28334PTPQ implements the C28x CPU core with Harvard bus architecture, unified memory model, and hardware FPU - enabling deterministic floating-point math for real-time closed-loop control. Its peripheral set includes six ePWM modules with high-resolution HRPWM outputs, two independent eCAN controllers supporting ISO 11898-1, and a 12-bit ADC with dual sample-and-hold and simultaneous sampling capability across 16 channels.
System-level features include a 6-channel DMA controller servicing ADC, ePWM, McBSP, XINTF, and SARAM; PIE block managing 58 peripheral interrupts; and 128-bit security key/lock protecting flash, OTP, and RAM. Clocking uses on-chip oscillator with PLL support, and low-power modes (IDLE, STANDBY, HALT) enable dynamic power management in battery-sensitive applications.
