Texas Instruments F2800156EPHPQ1

Overview

F2800156EPHPQ1 from Texas Instruments is an automotive-grade real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 100MHz, IEEE 754 FPU, 256KB ECC-protected flash, and 36KB ECC/parity-protected RAM. 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 for motor control in DC/DC converters and HVAC compressor modules.

For engineers reviewing the F2800156EPHPQ1 datasheet, F2800156EPHPQ1 pinout, F2800156EPHPQ1 application, or F2800156EPHPQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 100MHz CPU frequency, HTQFP-48 package with thermal pad, dual-core lockstep architecture, and integrated analog-peripheral timing synchronization for power electronics control loops.

Technical Context

The F2800156EPHPQ1 implements a dual-C28x lockstep core architecture with deterministic real-time execution, supported by TMU and VCRC acceleration units for trigonometric and CRC-intensive control algorithms. Its memory subsystem includes 256KB of single-bank flash with ECC and 36KB of RAM with parity/ECC protection, enabling robust code and data integrity in automotive environments.

System-level timing is managed via dual internal 10MHz oscillators, crystal/external clock input, windowed watchdog, missing-clock detection, and dual-clock comparator (DCC). Analog signal chain performance is enhanced by tight coupling between ADCs, CMPSS blocks (including 12-bit DAC-based ramp generators), and ePWM modules for closed-loop power stage control.

FAQ

What is the maximum operating frequency of the F2800156EPHPQ1?

The F2800156EPHPQ1 operates at a maximum CPU frequency of 100MHz. This is confirmed in the Device Information table and distinguishes it from the 120MHz F2800157-Q1 variant. The 100MHz clock is derived from the internal PLL and supports deterministic real-time execution for motor control and digital power applications without exceeding thermal or timing margins in the HTQFP-48 package.

Does the F2800156EPHPQ1 include a floating-point unit (FPU)?

Yes, the F2800156EPHPQ1 includes an IEEE 754-compliant 32-bit floating-point unit (FPU32). This accelerator is integral to the C28x CPU and enables efficient execution of floating-point math in field-oriented control (FOC), sensor fusion, and adaptive filtering algorithms without software emulation overhead.

What functional safety certifications apply to the F2800156EPHPQ1?

The F2800156EPHPQ1 is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. These certifications cover hardware safety mechanisms including lockstep CPU checking, memory ECC/parity, watchdog timers, and dual-clock comparators-enabling its use in automotive safety-related systems without requiring external safety monitors.

Which package type does the F2800156EPHPQ1 use, and what are its thermal characteristics?

The F2800156EPHPQ1 uses the 48-pin HTQFP (PHP) package with PowerPAD™ thermal enhancement. Its nominal body size is 9mm × 9mm with a 7mm × 7mm die pad area. Thermal resistance (θ_JA) is 32.5°C/W, enabling reliable operation at 125°C ambient in motor drive applications with appropriate PCB copper pour and thermal vias.

How many high-resolution PWM channels does the F2800156EPHPQ1 support?

The F2800156EPHPQ1 supports four high-resolution ePWM channels with 150ps resolution. These are implemented on ePWM1–ePWM4 and are used for precise gate driving in SiC/GaN-based power stages, where sub-nanosecond dead-time control minimizes shoot-through risk and switching losses.
