Product details
Overview
F2800157QPNQ1 from Texas Instruments is a dual-core lockstep C28x real-time microcontroller for automotive power electronics control, featuring 120MHz operation, 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, IEEE 754 FPU, TMU, and VCRC acceleration. It integrates 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 engineers reviewing the F2800157QPNQ1 datasheet, F2800157QPNQ1 pinout, F2800157QPNQ1 application, or F2800157QPNQ1 equivalent, this page delivers verified technical context, key specifications, package mapping, functional safety design implications, and automotive-grade peripheral interoperability details required for motor control, DC/DC converter, and battery management system implementation.
Technical Context
The F2800157QPNQ1 implements dual TMS320C28x CPUs in hardware lockstep with synchronized instruction execution and error-detection logic, enabling ASIL B compliance without software overhead. Its real-time signal chain includes tightly coupled 4MSPS ADCs with four post-processing blocks per channel and a dedicated 12-bit DAC-based windowed comparator (CMPSS) for fast overcurrent protection.
System-level timing relies on dual internal 10MHz oscillators, crystal/external clock input, and a programmable PLL; power integrity is maintained via 1.2V core (internal VREG) and 3.3V I/O domains with brownout reset. Communication interfaces include PMBus, dual I²C, SCI (3), LIN, SPI, CAN, and CAN FD-each supported across multiple pin-mux options in the 80-pin LQFP package.
