Product details
Overview
F2800156QPHPQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 100 MHz, IEEE 754 FPU, TMU, and VCRC acceleration. It integrates 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, 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 DC/DC converters and HVAC compressor modules.
For engineers reviewing the F2800156QPHPQ1 datasheet, F2800156QPHPQ1 pinout, F2800156QPHPQ1 application, or F2800156QPHPQ1 equivalent, key selection criteria include its 100 MHz dual-core lockstep operation, HTQFP-48 package with thermal enhancement, ASIL B certification, 256KB flash size, and support for CAN FD, PMBus, and high-resolution PWM in power electronics control systems.
Technical Context
The F2800156QPHPQ1 implements a dual-C28x CPU lockstep architecture with hardware-level fault detection, enabling deterministic real-time execution and systematic capability up to ASIL D. Its analog subsystem includes two synchronized 12-bit ADCs with four post-processing blocks per ADC and one full CMPSS with 12-bit DAC ramp generators.
Control peripherals are tightly coupled via XBARs: 14 ePWM channels (4 high-resolution) feed directly into dead-band logic and hardware trip zones, while three eCAP and two eQEP modules support precise timing capture and position feedback for motor commutation and encoder-based motion control.
