Texas Instruments F2800157QPHPRQ1

Overview

TMS320F2800157QPHPRQ1 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, 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 per ISO 26262 for motor control in EV inverters and DC/DC converters.

For engineers reviewing the TMS320F2800157QPHPRQ1 datasheet, TMS320F2800157QPHPRQ1 pinout, TMS320F2800157QPHPRQ1 application, or TMS320F2800157QPHPRQ1 equivalent, this page delivers verified technical context, package-specific pin mapping, safety-critical peripheral integration details, and validated alternative options for automotive powertrain designs requiring deterministic real-time control and fault containment.

Technical Context

The TMS320F2800157QPHPRQ1 implements dual C28x cores executing in hardware-enforced lockstep to achieve ASIL B compliance without software overhead. Its analog subsystem tightly couples two 4MSPS 12-bit ADCs with four post-processing blocks per converter and a dedicated 12-bit ramp-generator DAC for CMPSS, enabling closed-loop timing-critical feedback in power stage control.

System-level safety is reinforced by memory power-on self-test (MPOST), dual-clock comparator (DCC), windowed watchdog, brownout reset, and dual-zone security with JTAGLOCK and zero-pin boot. The device supports multiple low-power modes and features integrated dead-band generation, hardware trip zones, and embedded pattern generation for robust gate-driver interfacing.
