Texas Instruments F280045PMS

Overview

TMS320F280045PMS from Texas Instruments is a 32-bit real-time microcontroller (MCU) with 100MHz C28x CPU, IEEE 754 FPU, and CLA accelerator, designed for high-precision motor control and digital power conversion. It integrates three 3.45MSPS 12-bit ADCs, 16 ePWM channels with 150ps resolution, dual CAN interfaces, and 128KB flash/100KB RAM - deployed in EV charging stations and solar string inverters.

For engineers reviewing the TMS320F280045PMS datasheet, TMS320F280045PMS pinout, TMS320F280045PMS application, or TMS320F280045PMS equivalent, key selection criteria include CLA offload capability, analog front-end PGA gain options (3/6/12/24), SDFM sigma-delta filtering support, and 64-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).

Technical Context

The TMS320F280045PMS implements a dual-core real-time control architecture: the main C28x CPU executes deterministic control loops at 100MHz with TMU/VCU-I acceleration for fast trigonometric and complex math, while the independent CLA runs parallel floating-point tasks (e.g., current loop calculations) without CPU intervention. Both cores share access to ECC-protected memory and synchronized peripherals.

Its analog subsystem features seven programmable gain amplifiers (PGAs), three independent ADCs with four post-processing blocks each, and seven windowed comparators with integrated 12-bit DAC references - enabling simultaneous high-speed sampling, on-chip signal conditioning, and hardware-triggered trip actions for overcurrent/overvoltage protection in power stages.

FAQ

What is the maximum operating frequency of the TMS320F280045PMS CPU?

The TMS320F280045PMS features a TMS320C28x 32-bit CPU running at 100MHz. This clock speed is fixed and supported across its full industrial temperature range (–40°C to 125°C). The device also includes a separate 100MHz Control Law Accelerator (CLA) that operates concurrently with the main CPU, enabling parallel execution of time-critical control algorithms without affecting CPU bandwidth. Both cores derive timing from the same system clock domain.

Does the TMS320F280045PMS include a hardware floating-point unit?

Yes, the TMS320F280045PMS integrates an IEEE 754 single-precision Floating-Point Unit (FPU) within its C28x CPU. This FPU accelerates mathematical operations essential for real-time control - including division, square root, and transcendental functions - eliminating reliance on slower software emulation. The FPU is fully supported by TI's C2000 compiler toolchain and works in conjunction with the Trigonometric Math Unit (TMU) and Viterbi/Complex Math Unit (VCU-I) for optimized motor and power conversion algorithms.

What analog peripherals are integrated into the TMS320F280045PMS?

The TMS320F280045PMS integrates three independent 12-bit Analog-to-Digital Converters (ADCs), each capable of 3.45MSPS sampling. It includes seven Programmable Gain Amplifiers (PGAs) with selectable gains of 3, 6, 12, or 24, seven windowed comparators (CMPSS) with integrated 12-bit reference DACs, two buffered DAC outputs, and four Sigma-Delta Filter Module (SDFM) input channels. These peripherals collectively support high-accuracy current/voltage sensing, hardware-based fault detection, and isolated sensor interfacing in power electronics applications.

Is the TMS320F280045PMS pin-compatible with other devices in the F28004x family?

The TMS320F280045PMS uses the 64-pin LQFP (PM) package and shares identical pinout and electrical characteristics with other PM-package F28004x variants, including TMS320F280041PMS and TMS320F280048PMS. Pin compatibility is confirmed across all GPIO, power, analog, and communication signals in this package variant. However, feature availability (e.g., CLA, CLB, InstaSPIN-FOC™) differs between part numbers - functionality must be validated per device datasheet, even when pinouts match.

What functional safety certifications apply to the TMS320F280045PMS?

The TMS320F280045PMS is classified as Functional Safety Quality-Managed (FS-QM) per TI's documentation. While it supports hardware features required for safety-critical design - including ECC memory, ERAD debug module, windowed watchdog, and BOR circuit - it is not individually certified to ASIL B or SIL 3. Certified alternatives include F280048CPMQR and F280049PZQR. System-level compliance must be achieved through proper implementation per ISO 26262 or IEC 61508 guidelines using TI's Functional Safety Manual.
