Texas Instruments F2800156QPHPRQ1

Overview

F2800156QPHPRQ1 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 F2800156QPHPRQ1 datasheet, F2800156QPHPRQ1 pinout, F2800156QPHPRQ1 application, or F2800156QPHPRQ1 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 alignment for power electronics control loops.

Technical Context

The F2800156QPHPRQ1 implements a dual-C28x lockstep core architecture with deterministic 100MHz execution, enabling ASIL B compliance without software overhead. Its analog subsystem tightly couples two 4MSPS ADCs and four post-processing blocks per ADC with ePWM trigger synchronization for closed-loop timing accuracy within ±1ns jitter.

System-level safety is enforced via hardware-based DCSM security zones, JTAGLOCK, zero-pin boot, and memory power-on self-test (MPOST). The device supports multiple clock sources-including crystal oscillator, dual 10MHz internal oscillators with ExtR resistor tuning-and includes windowed watchdog, missing-clock detection, and dual-clock comparator (DCC) for runtime fault monitoring.

FAQ

What is the maximum operating frequency of the F2800156QPHPRQ1?

The F2800156QPHPRQ1 operates at a maximum CPU frequency of 100MHz. This is confirmed in the Device Information table and Device Comparison section of the official datasheet (SPRSP68D), where F2800156-Q1 is explicitly listed with "Frequency (MHz): 100". The dual C28x cores execute synchronously in lockstep at this rate, ensuring deterministic timing for real-time control tasks.

Does the F2800156QPHPRQ1 support CAN FD communication?

Yes, the F2800156QPHPRQ1 includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) bus port, as specified in the "Communications peripherals" section and confirmed in Table 4-1 (Device Comparison). This enables data rates up to 5Mbps and payloads up to 64 bytes, supporting modern automotive communication requirements such as OTA updates and high-bandwidth sensor fusion in ADAS systems.

What package type does the F2800156QPHPRQ1 use?

The F2800156QPHPRQ1 uses the 48-pin PowerPAD™ Thermally Enhanced Thin Quad Flatpack (HTQFP), designated by the "PHP" suffix in TI's nomenclature. This is verified in the Package Information table and Device Comparison, where F2800156-Q1 is listed with "PHP (HTQFP, 48)" and "9mm × 9mm" package size. The exposed thermal pad supports efficient heat dissipation in high-power automotive modules.

Is the F2800156QPHPRQ1 qualified for automotive applications?

Yes, the F2800156QPHPRQ1 is AEC-Q100 Grade 1 qualified and certified to ISO 26262 ASIL B by TÜV SÜD. The "Q1" suffix denotes automotive qualification, and the Device Information table explicitly lists it under "AEC-Q100: Grade 1" with operating temperature range –40°C to 125°C. Functional safety documentation and hardware safety mechanisms (lockstep, DCC, MPOST) are provided to support system-level ASIL B compliance.

How much flash memory does the F2800156QPHPRQ1 have?

The F2800156QPHPRQ1 contains 256KB (128KW) of single-bank flash memory with ECC protection, as stated in the Device Information table and Feature list. This capacity supports complex control algorithms, safety monitor routines, and dual-bank firmware images for robust field updates-consistent across all F2800156-Q1 variants regardless of package option.
