Product details
Overview
F2800155SPHPR from Texas Instruments is a dual-core C28x real-time microcontroller with lockstep safety architecture, 120MHz operation, IEEE 754 FPU, TMU, and 128KB ECC-protected flash. It integrates two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD interface, and functional safety certification up to ASIL B for automotive powertrain and industrial motor control.
For engineers reviewing the F2800155SPHPR datasheet, F2800155SPHPR pinout, F2800155SPHPR application, or F2800155SPHPR equivalent, this page delivers verified specifications, package mapping, functional safety context, and direct alternative part comparisons for automotive BMS, inverter control, and DC/DC converter designs.
Technical Context
The F2800155SPHPR implements dual TMS320C28x CPUs in lockstep with hardware-level fault detection, enabling ASIL B compliance without software overhead. Its real-time signal chain includes tightly coupled ADCs with four post-processing blocks per channel and integrated CMPSS with 12-bit DACs for fast analog loop closure.
It supports multiple clock sources - dual 10MHz internal oscillators, crystal input, or external clock - and features a windowed watchdog timer, missing-clock detection, and dual-clock comparator (DCC) for robust system monitoring in harsh environments.

FAQ
What is the operating temperature range for F2800155SPHPR?
The F2800155SPHPR is rated for –40°C to 125°C ambient temperature (TA), matching the industrial-grade F280015xS series specification. This range supports deployment in under-hood automotive modules and industrial enclosures without forced cooling, provided PCB thermal design meets TI's recommended layout guidelines for the PHP package.
Does F2800155SPHPR support CAN FD communication?
Yes, F2800155SPHPR includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) bus port compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps and payloads up to 64 bytes - enabling high-bandwidth diagnostics and firmware updates in modern vehicle networks.
How many high-resolution PWM channels does F2800155SPHPR provide?
F2800155SPHPR provides four ePWM channels with high-resolution capability (150 ps resolution): ePWM1 and ePWM2 on both A and B outputs. These channels support fine-grained dead-time control and phase-shifted modulation essential for SiC/GaN-based power converters.
Is F2800155SPHPR pin-compatible with other F280015x variants?
No, F2800155SPHPR uses the 48-pin HTQFP (PHP) package, while other variants like F2800155-Q1 offer RHB (32-pin VQFN) or PN/PM (80/64-pin LQFP) options. Pin counts, layouts, and thermal pad configurations differ - direct replacement requires PCB redesign and signal reassignment.
What functional safety documentation is available for F2800155SPHPR?
Texas Instruments provides ISO 26262 ASIL B certification reports (TÜV SÜD), safety manual, FMEDA data, and hardware/software safety analysis packages for F2800155SPHPR.
