Texas Instruments F2800155QPNRQ1

Overview

F2800155QPNRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 120 MHz, IEEE 754 FPU, Trigonometric Math Unit (TMU), and 128KB flash with ECC protection. It integrates two 4-MSPS 12-bit ADCs, 14 ePWM channels (4 with 150-ps resolution), one CAN FD/MCAN port, and functional safety support up to ASIL B for motor control and power electronics systems.

For engineers reviewing the F2800155QPNRQ1 datasheet, F2800155QPNRQ1 pinout, F2800155QPNRQ1 application, or F2800155QPNRQ1 equivalent, key selection considerations include its dual-core lockstep architecture for fault detection, integrated analog signal chain with post-processing blocks, high-resolution PWM for precise timing control, and automotive-grade thermal and qualification compliance (–40°C to 125°C).

Technical Context

The F2800155QPNRQ1 implements a dual-C28x lockstep CPU subsystem with hardware-level redundancy checking, enabling deterministic fault detection without software overhead. Its real-time control pipeline includes dedicated accelerators-FPU32, TMU, and VCRC-for fast execution of motor control algorithms, trigonometric computations, and CRC-based integrity checks.

Analog-to-digital conversion is tightly coupled to control peripherals via two independent 12-bit ADCs (4 MSPS each) with four post-processing blocks per ADC and integrated windowed comparators (CMPSS with 12-bit DACs). The device supports flexible clocking with dual internal 10-MHz oscillators, crystal input, and missing-clock detection for robust system timing.

FAQ

What is the maximum operating frequency of the F2800155QPNRQ1?

The F2800155QPNRQ1 operates at a maximum CPU frequency of 120 MHz. This applies to both C28x cores running in lockstep mode. The PLL supports stable operation across the full temperature range (–40°C to 125°C), and all peripherals-including ADCs, ePWM, and communications interfaces-are fully functional at this rate. Timing margins are validated per TI's recommended operating conditions in the datasheet.

Does the F2800155QPNRQ1 support CAN FD communication?

Yes, the F2800155QPNRQ1 includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) port compliant with ISO 11898-1:2015. It supports data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B. The MCAN module includes message RAM, error counters, and loopback self-test modes verified in TI's functional safety documentation.

How much flash memory does the F2800155QPNRQ1 have, and is it ECC-protected?

The F2800155QPNRQ1 contains 128KB (64KW) of on-chip flash memory, organized in 64 sectors. All flash is protected by single-bit error correction and double-bit error detection (SECDED) using hardware ECC logic. This protection is active during both read and program/erase operations and is integral to the device's ASIL B functional safety certification.

What analog peripherals are integrated into the F2800155QPNRQ1?

The F2800155QPNRQ1 integrates two independent 12-bit analog-to-digital converters (ADCs), each capable of 4 million samples per second (MSPS). Each ADC includes four post-processing blocks (PPB) for real-time filtering and correction. It also features one full-featured comparator subsystem (CMPSS) with 12-bit DACs and ramp generators, plus three lightweight comparators (CMPSS_LITE) with 9.5-bit effective DACs.

Is the F2800155QPNRQ1 qualified for automotive applications?

Yes, the F2800155QPNRQ1 is AEC-Q100 Grade 1 qualified and ISO 26262 ASIL B certified by TÜV SÜD. It is rated for operation from –40°C to 125°C ambient temperature and includes built-in diagnostic features such as memory POST, windowed watchdog timer, missing clock detection, and dual-clock comparator (DCC) - all documented in TI's functional safety manual SPRUIJ9.
