Product details
Overview
F2800156QPMRQ1 from Texas Instruments is an automotive-grade real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 100 MHz, IEEE 754 FPU, 256KB flash (ECC-protected), 36KB RAM (ECC/parity-protected), and AEC-Q100 Grade 1 qualification for operation from –40°C to 125°C. 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 per ISO 26262.
For engineers reviewing the F2800156QPMRQ1 datasheet, F2800156QPMRQ1 pinout, F2800156QPMRQ1 application, or F2800156QPMRQ1 equivalent, key selection criteria include its 100-MHz dual-core lockstep architecture, automotive temperature range, integrated high-resolution PWM and CAN FD, and hardware-level functional safety features for motor control and power conversion systems.
Technical Context
The F2800156QPMRQ1 implements a dual-C28x CPU lockstep architecture with shared instruction fetch and parallel execution monitoring, enabling hardware-level fault detection without software overhead. Its real-time control subsystem includes dedicated accelerators: Trigonometric Math Unit (TMU) for fast sine/cosine computation and VCRC engine for CRC-32/CRC-16 acceleration in communication and firmware integrity checks.
System-level timing is managed via dual internal 10-MHz oscillators, external crystal support, and a programmable PLL; clock integrity is enforced by missing-clock detection and a windowed watchdog timer. Analog signal chain performance is enhanced by four post-processing blocks (PPB) per ADC and integrated windowed comparators with 12-bit DAC references.
