Texas Instruments F2800155SPNR

Overview

F2800155SPNR from Texas Instruments is a dual-core C28x real-time microcontroller with lockstep architecture, 120MHz operation, IEEE 754 FPU, TMU, and VCRC engine. It integrates 128KB ECC-protected flash, 36KB ECC/parity-protected RAM, two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD port, and functional safety certification up to ASIL B for automotive motor control and digital power applications.

For engineers reviewing the F2800155SPNR datasheet, F2800155SPNR pinout, F2800155SPNR application, or F2800155SPNR equivalent, key selection criteria include dual-C28x lockstep execution, 128KB flash size, 120MHz clock speed, CAN FD interface support, and AEC-Q100 Grade 1 qualification in the 64-pin LQFP package.

Technical Context

The F2800155SPNR implements two identical TMS320C28x CPUs operating in lockstep for fault detection, with shared memory and synchronized instruction execution. Its real-time control subsystem includes dedicated hardware accelerators - Trigonometric Math Unit (TMU) for sine/cosine/arctan, and VCRC engine for fast CRC computation - tightly coupled to the CPU pipeline.

System-level timing is managed via dual internal 10MHz oscillators, crystal/external clock input, PLL-based frequency synthesis, windowed watchdog timer, missing-clock detection, and Dual-Clock Comparator (DCC). The analog subsystem features two independent 12-bit ADCs with four post-processing blocks each and one full-featured CMPSS with 12-bit DAC plus three CMPSS_LITE modules.
