Texas Instruments TMS320F28062FPNT

Overview

TMS320F28062FPNT from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and high-resolution PWM peripherals, designed for closed-loop motor control and digital power conversion. It delivers 11.11-ns instruction cycle time, 12-bit 3.46-MSPS ADC with dual sample-and-hold, and 16 ePWM channels (8 HRPWM-capable), operating from a single 3.3-V supply in industrial temperature range (–40°C to 105°C).

For engineers reviewing the TMS320F28062FPNT datasheet, TMS320F28062FPNT pinout, TMS320F28062FPNT application, or TMS320F28062FPNT equivalent, this page provides verified functional specifications, package mapping to 80-pin LQFP (PN), validated peripheral roles, and direct alternative options for motor drive and inverter design.

Technical Context

The TMS320F28062FPNT implements a Harvard-architecture C28x CPU with atomic operations and unified memory model, coupled with a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU. Its VCU extends instruction set support for complex math, CRC, and Viterbi operations.

Peripheral integration includes three eCAP modules, four HRCAP modules, two eQEP interfaces, dual SCI/UART, dual SPI, I²C, eCAN, and USB 2.0 - all accessible via a 32-bit peripheral bus with DMA support. The device uses on-chip oscillators and PLL-based clocking with missing-clock detection and watchdog timer.

Key Specifications

Pinout & Package

Package: 80-pin Low-Profile Quad Flatpack (LQFP, PN), 12 mm × 12 mm body with exposed thermal pad (PowerPAD™). The pad is electrically isolated from die VSS and must be soldered to PCB ground plane via thermal vias for effective heat dissipation.

FAQ

What is the maximum ADC sampling rate supported by the TMS320F28062FPNT?

The TMS320F28062FPNT supports a maximum ADC conversion rate of 3.46 million samples per second (MSPS) with its 12-bit dual sample-and-hold architecture. This allows simultaneous sampling of up to two analog signals (e.g., phase current and DC-link voltage) within a single 289-ns conversion window. The ADC is tightly synchronized with ePWM triggers to ensure precise timing alignment in motor control loops.

Does the TMS320F28062FPNT include a hardware security module?

Yes, the TMS320F28062FPNT integrates a Code Security Module (CSM) with 128-bit password protection and one-time programmable (OTP) ROM. This secures on-chip flash, SARAM, and OTP memory blocks against unauthorized read-out or firmware cloning. The CSM enforces secure boot and prevents debugger access unless explicitly unlocked with the correct password sequence.

Which communication interfaces are available on the TMS320F28062FPNT?

The TMS320F28062FPNT provides two SCI/UART modules, two SPI modules, one I²C bus, one eCAN controller, one McBSP interface, and full-speed USB 2.0 device-mode support. All interfaces are DMA-accessible and mapped to the 32-bit peripheral bus. Notably, USB operates in device-only mode and does not support host functionality.

What is the role of the CLA in the TMS320F28062FPNT?

The Control Law Accelerator (CLA) in the TMS320F28062FPNT is an independent 32-bit floating-point processor that executes control algorithms - such as PID, FOC, or observers - in parallel with the main C28x CPU. It accesses shared RAM and peripherals directly, enabling sub-microsecond loop execution without CPU intervention, critical for high-bandwidth motor and power control.

Is the TMS320F28062FPNT pin-compatible with other F2806x family members?

No, the TMS320F28062FPNT is not pin-compatible with 100-pin variants like TMS320F28069PZP. It uses the 80-pin LQFP (PN) package, whereas higher-feature variants use 100-pin LQFP (PZ) or HTQFP (PZP/PFP) packages. Pin assignments differ significantly between 80-pin and 100-pin versions, requiring distinct PCB layouts and signal routing.
