Product details
Overview
F2800154QRHBRQ1 from Texas Instruments is a functional-safety-compliant, dual-core C28x real-time microcontroller for automotive power electronics control. It operates at 120MHz with IEEE 754 FPU, TMU, and VCRC acceleration; integrates 128KB ECC-protected flash, 36KB ECC/parity-protected RAM; supports CAN FD, PMBus, and 14 ePWM channels (4 with 150ps resolution); and targets ASIL B–compliant inverter & motor control systems.
For engineers reviewing the F2800154QRHBRQ1 datasheet, F2800154QRHBRQ1 pinout, F2800154QRHBRQ1 application, or F2800154QRHBRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 120MHz lockstep dual-C28x performance, 32-pin VQFN thermal package, integrated analog subsystem (dual 4MSPS ADCs + CMPSS), and functional safety documentation for ISO 26262 system integration.
Technical Context
The F2800154QRHBRQ1 implements dual TMS320C28x CPUs in hardware lockstep to achieve ASIL B compliance without software redundancy overhead. Its real-time control subsystem includes dedicated accelerators: Trigonometric Math Unit (TMU) for fast sine/cosine and arctan, and VCRC engine for CRC-16/32 computation in single-cycle instructions.
It features two independent 4MSPS, 12-bit ADCs with up to 21 external channels and four post-processing blocks per ADC, plus one full CMPSS with 12-bit ramp DAC and three CMPSS_LITE modules with 9.5-bit static DACs - tightly coupled to ePWM modules for closed-loop timing-critical protection.
