Texas Instruments TMS320F28062PFPS

Overview

TMS320F28062PFPS from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and 12-bit 3.46-MSPS ADC, designed for closed-loop motor control and digital power conversion in industrial inverters and EV charging modules.

For engineers reviewing the TMS320F28062PFPS datasheet, TMS320F28062PFPS pinout, TMS320F28062PFPS application, or TMS320F28062PFPS equivalent, key selection factors include its 80-pin HTQFP package, 64KB flash/34KB RAM configuration, ePWM with HRPWM capability, dual-sample-and-hold ADC, and USB 2.0 support in select variants.

Technical Context

The TMS320F28062PFPS implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, paired with a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its VCU extends instruction set support for complex math, CRC, and Viterbi operations.

Peripheral integration includes eight ePWM modules (16 total channels, 8 HRPWM-capable), three eCAP, four HRCAP, two eQEP, dual SCI/UART, two SPI, one I²C, one eCAN, one McBSP, and full-speed USB 2.0 - all accessible via DMA and coordinated through a centralized PIE interrupt controller.

FAQ

What is the maximum operating frequency of the TMS320F28062PFPS?

The TMS320F28062PFPS operates at a maximum CPU clock frequency of 90 MHz, corresponding to an 11.11-ns instruction cycle time. This frequency is achieved using the on-chip PLL with either internal oscillators or external crystal input (X1/X2). The device maintains full peripheral functionality and timing specifications at this speed, as validated across the –40°C to 125°C temperature range.

Does the TMS320F28062PFPS include USB functionality?

No, the TMS320F28062PFPS does not include USB functionality. While the F2806x family includes USB on U/M/F variants, the TMS320F28062PFPS is explicitly excluded from USB support per the official device comparison table (Table 5-1, SPRS698J). Pins 26 and 27 are assigned to ECAP3/SPICLKB and HRCAP2/SPISTEB/USB0DM respectively, confirming USB is not implemented on this variant.

What is the flash memory capacity of the TMS320F28062PFPS?

The TMS320F28062PFPS integrates 64KB of on-chip flash memory organized as 16-bit words. This capacity is partitioned into eight equal sectors for flexible erase/write operations and supports secure code protection via the CSM module. It is sufficient for typical FOC or DQ-based motor control firmware with calibration tables and communication stacks.

Which package type and thermal features does the TMS320F28062PFPS use?

The TMS320F28062PFPS uses the 80-pin HTQFP (PFP) package with PowerPAD™ thermal enhancement. The exposed thermal pad must be soldered to a PCB ground plane using an array of thermal vias - it is not electrically connected to internal VSS. This construction achieves lower junction-to-board thermal resistance, critical for sustained operation at 125°C ambient in enclosed power modules.

How many high-resolution PWM channels does the TMS320F28062PFPS support?

The TMS320F28062PFPS supports 8 high-resolution PWM (HRPWM) channels, distributed across its eight ePWM modules. Each HRPWM channel provides 150-ps resolution for fine edge positioning, enabling precise dead-time control and frequency modulation in wide-bandgap power stages - confirmed in the device comparison table and functional block diagram.
