Texas Instruments F2800155QPHPRQ1

Overview

F2800155QPHPRQ1 from Texas Instruments is an automotive-grade real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 120MHz, IEEE 754 FPU, Trigonometric Math Unit (TMU), and 128KB ECC-protected flash. 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 F2800155QPHPRQ1 datasheet, F2800155QPHPRQ1 pinout, F2800155QPHPRQ1 application, or F2800155QPHPRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 128KB flash size, HTQFP-48 package with thermal pad, dual-core lockstep architecture for fault detection, and integrated analog-peripheral coupling for real-time power stage control.

Technical Context

The F2800155QPHPRQ1 implements a dual-C28x lockstep CPU subsystem with FPU32, TMU, and VCRC acceleration to enable deterministic real-time control of power electronics. Its memory subsystem includes 128KB flash (ECC-protected) and 36KB RAM (ECC/parity-protected), with DCSM-based dual-zone security and zero-pin boot capability.

Peripherals are tightly coupled for low-latency signal chains: two 4MSPS ADCs feed four post-processing blocks per converter; 14 ePWM channels (4 high-resolution) support dead-band generation and hardware trip zones; and communication interfaces include MCAN, PMBus, SPI, three SCI, two I²C, LIN, and CAN.

FAQ

What is the maximum operating frequency of the F2800155QPHPRQ1?

The F2800155QPHPRQ1 operates at a maximum CPU frequency of 120MHz. This speed applies to both C28x cores running in lockstep mode and is sustained across the full –40°C to 125°C ambient temperature range. The device achieves this performance using an internal PLL fed by either an external crystal or its dual 10MHz internal oscillators, with ExtR resistor tuning for improved stability. All timing-critical peripherals-including ePWM, ADC, and CAN FD-are synchronized to this clock domain.

Does the F2800155QPHPRQ1 support functional safety certification?

Yes, the F2800155QPHPRQ1 is ISO 26262 certified up to ASIL B by TÜV SÜD and IEC 61508 certified up to SIL 2. Certification covers hardware integrity, diagnostic coverage, and systematic capability, with built-in features including dual-core lockstep comparison, memory ECC/parity, windowed watchdog timer, missing clock detection, and dual-clock comparator (DCC). Documentation for system-level integration-including safety manuals and FMEDA reports-is available from Texas Instruments.

What package type does the F2800155QPHPRQ1 use?

The F2800155QPHPRQ1 uses the 48-pin PowerPAD™ Thermally Enhanced Thin Quad Flatpack (HTQFP) package, designated PHP suffix. It measures 9mm × 9mm with a 7mm × 7mm body and includes an exposed thermal pad on the underside for direct PCB thermal vias. This package is AEC-Q100 Grade 1 qualified and supports junction temperatures up to 140°C, making it suitable for under-hood automotive environments with high power dissipation requirements.

How much flash memory does the F2800155QPHPRQ1 have?

The F2800155QPHPRQ1 contains 128KB (64KW) of on-chip flash memory, implemented as a single bank with full ECC protection. This memory is organized into 64 sectors and supports read-while-write operation, allowing background firmware updates without halting real-time control execution. Flash endurance is rated for 1,000 program/erase cycles, and data retention exceeds 20 years at 125°C junction temperature.

Which communication interfaces are integrated into the F2800155QPHPRQ1?

The F2800155QPHPRQ1 integrates one MCAN (CAN FD) port, one PMBus interface, one SPI port, three UART-compatible SCI modules, one LIN interface, and two I²C ports. All interfaces support pin multiplexing across GPIOs, with dedicated hardware FIFOs and DMA triggers. The MCAN module supports bit rates up to 5Mbps and payloads up to 64 bytes, while PMBus enables direct digital power management with SMBus 2.0 compatibility.
