Texas Instruments F2800155QPMRQ1

Overview

F2800155QPMRQ1 from Texas Instruments is an automotive-grade real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 120MHz, IEEE 754 FPU, Trigonometric Math Unit (TMU), and 128KB ECC-protected flash. It integrates two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD/MCAN port, and functional safety certification up to ASIL B for motor control in electric powertrain systems.

For engineers reviewing the F2800155QPMRQ1 datasheet, F2800155QPMRQ1 pinout, F2800155QPMRQ1 application, or F2800155QPMRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 64-pin LQFP package with 37 GPIOs (11 shared with analog), dual-zone security, and support for high-resolution PWM-driven inverter gate timing in automotive DC/DC converters and on-board chargers.

Technical Context

The F2800155QPMRQ1 implements a lockstep dual-C28x CPU architecture with hardware redundancy checking, enabling ASIL B compliance without significant software overhead. Its real-time signal chain includes tightly coupled 4MSPS ADCs with four post-processing blocks per converter and integrated windowed comparators with 12-bit DACs for fast overcurrent protection.

System-level timing is managed via dual internal 10MHz oscillators, crystal/external clock input, windowed watchdog, missing-clock detection, and Dual-Clock Comparator (DCC). The device operates at 1.2V core and 3.3V I/O with internal VREG and brownout reset, supporting automotive ambient temperatures from –40°C to 125°C.
