Texas Instruments F280041CPZQR

Overview

F280041CPZQR from Texas Instruments is a 32-bit real-time microcontroller (MCU) with 100MHz C28x CPU, IEEE 754 FPU, CLA accelerator, 128KB flash, and 100KB RAM. It integrates three 3.45MSPS 12-bit ADCs, seven PGAs, 16 ePWM channels with 150ps resolution, two CAN interfaces, and InstaSPIN-FOC™ ROM support-designed for high-precision motor control in EV charging power modules and solar inverters.

For engineers reviewing the F280041CPZQR datasheet, F280041CPZQR pinout, F280041CPZQR application, or F280041CPZQR equivalent, key selection criteria include its 100-pin LQFP package, ASIL-B functional safety compliance, CLA offloading capability, dual-zone security, and hardware trip zones for fast fault response in closed-loop power conversion systems.

Technical Context

The F280041CPZQR implements a dual-core real-time control architecture: the main C28x CPU executes at 100MHz with TMU/VCU-I acceleration for trigonometric and complex math, while the independent CLA runs parallel floating-point code at 100MHz with dedicated memory and direct peripheral access. Both cores share a unified bus architecture supporting deterministic interrupt latency via ePIE.

Its analog subsystem features three synchronized 12-bit ADCs (3.45MSPS), each with four post-processing blocks and integrated reference DACs; seven windowed comparators with 12-bit DACs enable real-time overvoltage/undervoltage monitoring; and seven programmable-gain amplifiers (gain settings: 3/6/12/24) condition signals before ADC conversion.

FAQ

What is the maximum operating frequency of the C28x CPU in the F280041CPZQR?

The C28x CPU in the F280041CPZQR operates at a maximum frequency of 100MHz. This clock speed enables deterministic execution of real-time control algorithms, including field-oriented control (FOC) loops, with sub-microsecond latency. The F280041CPZQR maintains this frequency across its full operating temperature range (–40°C to 125°C junction), ensuring consistent performance in demanding industrial and automotive environments.

Does the F280041CPZQR include hardware support for functional safety certification?

Yes, the F280041CPZQR is Functional Safety Quality-Managed (FS-QM) and supports system-level ASIL B compliance per ISO 26262. It includes hardware features such as ECC-protected memory, windowed watchdog timers, missing-clock detection, and hardware trip zones. While not individually certified like the F280049C-Q1, the F280041CPZQR provides the necessary architectural elements for developers to achieve ASIL B in end equipment when used with TI's Functional Safety Manual and diagnostic software libraries.

How many analog-to-digital converters does the F280041CPZQR integrate, and what are their key specifications?

The F280041CPZQR integrates three independent 12-bit analog-to-digital converters (ADCs), each capable of 3.45MSPS sampling with a 290ns conversion time. Each ADC supports up to 21 external input channels and includes four integrated post-processing blocks (PPBs) for real-time filtering and averaging. These ADCs are synchronized and share common reference voltages (VREFHIA/B/C and VREFLOA/B/C), enabling precise multi-channel acquisition for motor phase current and DC-link voltage measurement.

What communication interfaces are available on the F280041CPZQR?

The F280041CPZQR provides two Controller Area Network (CAN) ports, one Inter-Integrated Circuit (I2C) interface, two UART-compatible Serial Communication Interfaces (SCIs), two Serial Peripheral Interface (SPI) ports, one Local Interconnect Network (LIN) interface, one Power Management Bus (PMBus) interface, and one Fast Serial Interface (FSI). All interfaces except FSI are pin-bootable, allowing flexible configuration during startup. The dual CAN ports support redundancy and diagnostics in automotive and industrial networks.

Is the Configurable Logic Block (CLB) available on the F280041CPZQR?

Yes, the F280041CPZQR includes the Configurable Logic Block (CLB) with four programmable logic tiles. This feature is explicitly confirmed in TI's Device Comparison table for the F280041C variant. The CLB augments existing peripherals-such as ePWM and eCAP-to implement custom position manager logic, hardware-based protection states, or glue logic without consuming CPU cycles or requiring external FPGA components.
