Texas Instruments TMS320F28062PZPS

Overview

TMS320F28062PZPS 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 TMS320F28062PZPS datasheet, TMS320F28062PZPS pinout, TMS320F28062PZPS application, or TMS320F28062PZPS equivalent, this device delivers deterministic low-latency control via dual-edge HRPWM, on-chip analog comparators routed to ePWM, and secure firmware protection using 128-bit encryption and OTP ROM.

Technical Context

The TMS320F28062PZPS implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, enabling deterministic real-time response. Its CLA operates independently of the main CPU to offload floating-point control law computation, while the VCU accelerates complex math and CRC operations.

Peripheral integration includes eight ePWM modules (16 channels, 8 HRPWM-capable), three eCAP, four HRCAP, two eQEP, and dual-sample-and-hold ADC with ratio-metric reference support. The device uses a single 3.3-V supply with internal voltage regulation and supports JTAG boundary scan per IEEE 1149.1.

Key Specifications

Pinout & Package

The TMS320F28062PZPS is housed in a 100-pin PowerPAD™ Thermally Enhanced Thin Quad Flatpack (HTQFP), with the exposed thermal pad electrically isolated from die ground and requiring direct soldering to PCB ground plane for optimal thermal dissipation.

FAQ

What is the maximum operating frequency of the TMS320F28062PZPS?

The TMS320F28062PZPS operates at a maximum CPU frequency of 90 MHz, delivering a 11.11-ns instruction cycle time. This clock speed is achieved using an internal PLL with either an external crystal (X1/X2) or the on-chip zero-pin oscillators, and is fully supported across its –40°C to 125°C industrial temperature range. All timing-critical peripherals-including ePWM, ADC, and CLA-scale deterministically with this clock.

Does the TMS320F28062PZPS include a floating-point unit (FPU)?

Yes, the TMS320F28062PZPS integrates a native single-precision floating-point unit (FPU) that executes IEEE 754-compliant operations directly in hardware. This eliminates software emulation overhead and enables efficient implementation of complex control algorithms such as field-oriented control (FOC) and adaptive filtering-critical for high-fidelity real-time motor and power conversion applications using the TMS320F28062PZPS.

How many high-resolution PWM (HRPWM) channels does the TMS320F28062PZPS support?

The TMS320F28062PZPS supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel enables sub-150-ps duty-cycle resolution via digital window comparators and extended TBCLK prescaling-essential for resonant LLC and soft-switching topologies. These 8 channels are part of the device's total 16 ePWM outputs, all accessible on the 100-pin PZP package used by the TMS320F28062PZPS.

Is the TMS320F28062PZPS pin-compatible with other F2806x devices?

Yes, the TMS320F28062PZPS shares identical pinout and package (100-pin PZP HTQFP) with other PZP variants in the F2806x family-including TMS320F28069PZPS and TMS320F28067PZPS. This allows direct PCB reuse across models differing only in flash size, peripheral enablement (e.g., VCU), or feature sets-enabling scalable design migration without layout changes for the TMS320F28062PZPS.

What security features are implemented in the TMS320F28062PZPS?

The TMS320F28062PZPS includes hardware-based security features: a 128-bit password-protected Code Security Module (CSM), 1 KB of one-time programmable (OTP) ROM for secure key storage, and flash/SARAM locking to prevent unauthorized readout or reprogramming. These mechanisms protect firmware intellectual property and ensure boot integrity-key requirements for industrial and automotive deployments of the TMS320F28062PZPS.
