Product details
Overview
F2800157QRHBRQ1 from Texas Instruments is a functional-safety-certified real-time microcontroller with dual 32-bit C28x lockstep CPUs operating at 120MHz, IEEE 754 FPU, Trigonometric Math Unit (TMU), and 256KB ECC-protected flash. It integrates two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD/MCAN port, and supports ASIL B/SIL 2 compliance for automotive powertrain control.
For engineers reviewing the F2800157QRHBRQ1 datasheet, F2800157QRHBRQ1 pinout, F2800157QRHBRQ1 application, or F2800157QRHBRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 32-pin VQFN (RHB) package, -40°C to 125°C ambient operation, and integrated safety features including memory POST, dual-zone security, and windowed watchdog.
Technical Context
The F2800157QRHBRQ1 implements dual C28x cores in hardware lockstep for fault detection, enabling ASIL B compliance without significant software overhead. Its analog subsystem tightly couples two 12-bit ADCs (4MSPS) with four post-processing blocks per ADC and one CMPSS with 12-bit DAC for real-time closed-loop control.
Control peripherals include 14 ePWM channels with integrated dead-band generation and hardware trip zones, three eCAP modules, two eQEP modules supporting CW/CCW, and an embedded pattern generator. Communication is supported via PMBus, two I²C, one CAN, one CAN FD, three SCI, one LIN, and one SPI interface.
