Product details
Overview
F2800157QPNRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 120 MHz, IEEE 754 FPU, Trigonometric Math Unit (TMU), and 256KB ECC-protected flash. It integrates two 4-MSPS 12-bit ADCs, 14 ePWM channels (4 with 150-ps resolution), one CAN FD/MCAN port, and functional safety certification up to ASIL B for motor control in EV inverters and DC/DC converters.
For engineers reviewing the F2800157QPNRQ1 datasheet, F2800157QPNRQ1 pinout, F2800157QPNRQ1 application, or F2800157QPNRQ1 equivalent, key selection criteria include lockstep CPU architecture, ASIL B certification, 120-MHz deterministic timing, dual ADC throughput, and automotive-grade thermal range (–40°C to 125°C).
Technical Context
The F2800157QPNRQ1 implements a dual-core lockstep execution model where both C28x cores execute identical instructions with cycle-by-cycle comparison, enabling hardware-level fault detection without software overhead. Its real-time control subsystem includes dedicated accelerators-TMU for sine/cosine and VCRC for fast CRC computation-optimized for digital power and motor control loops.
It supports multiple boot modes including zero-pin boot and JTAGLOCK-secured debug access, with dual-zone security enforcing memory isolation between application and secure firmware. The analog subsystem tightly couples ADC sampling, post-processing blocks (PPB), and CMPSS comparators to ePWM triggers for sub-microsecond closed-loop response.
