Texas Instruments F2800156EPHPRQ1

Overview

F2800156EPHPRQ1 from Texas Instruments is an automotive-grade real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 100 MHz, IEEE 754 FPU, 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, and functional safety certification up to ASIL B per ISO 26262 for motor control and power electronics applications.

For engineers reviewing the F2800156EPHPRQ1 datasheet, F2800156EPHPRQ1 pinout, F2800156EPHPRQ1 application, or F2800156EPHPRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 100 MHz CPU frequency (vs. 120 MHz in F2800157-Q1), absence of high-resolution PWM channels, and support for CAN FD, dual I²C, three SCI, and two 4-MSPS 12-bit ADCs with four post-processing blocks each.

Technical Context

The F2800156EPHPRQ1 implements a dual-core lockstep architecture for fault detection in safety-critical systems, with dedicated hardware accelerators including Trigonometric Math Unit (TMU) and VCRC engine to accelerate real-time control algorithms. Its memory subsystem includes 256KB flash organized in 128 sectors with ECC protection and 36KB RAM split into M0/M1 (4KB) and LS0/LS1 (32KB) banks with parity/ECC coverage.

System-level timing relies on dual internal 10MHz oscillators, crystal oscillator input, or external clock source, with windowed watchdog timer, missing-clock detection, and Dual-Clock Comparator (DCC) for clock monitoring. The analog subsystem integrates two 12-bit ADCs (4 MSPS), one full CMPSS with 12-bit DAC, and three CMPSS_LITE modules with 9.5-bit DACs - all tightly coupled to ePWM and eCAP peripherals for deterministic signal chain latency.

FAQ

What is the maximum operating frequency of the F2800156EPHPRQ1?

The F2800156EPHPRQ1 operates at a maximum CPU frequency of 100 MHz. This is confirmed in the Device Information table and distinguishes it from the 120 MHz F2800157-Q1 variant. The 100 MHz clock is generated via the on-chip PLL from internal or external sources, and all peripherals-including ADC, ePWM, and communications interfaces-are fully functional at this rate. F2800156EPHPRQ1 maintains full real-time determinism and ASIL B compliance at this frequency.

Does the F2800156EPHPRQ1 support high-resolution PWM (HRPWM)?

No, the F2800156EPHPRQ1 does not include high-resolution PWM channels. According to the Device Comparison table, HRPWM capability (150 ps resolution) is present only in F2800157 and F2800153-Q1 variants. F2800156EPHPRQ1 provides 14 standard ePWM channels with integrated dead-band and trip-zone support, sufficient for conventional 3-phase inverter and PFC control but not for topologies requiring sub-nanosecond timing precision.

What package type is used for the F2800156EPHPRQ1?

The F2800156EPHPRQ1 uses the 48-pin PowerPAD™ Thermally Enhanced Thin Quad Flatpack (HTQFP), designated by the PHP suffix. This package measures 9mm × 9mm with a 7mm × 7mm body and features an exposed thermal pad for enhanced heat dissipation-critical for automotive power electronics applications where sustained thermal performance is required.

Is the F2800156EPHPRQ1 certified for automotive functional safety standards?

Yes, the F2800156EPHPRQ1 is ISO 26262 certified up to ASIL B by TÜV SÜD and IEC 61508 certified up to SIL 2. These certifications apply to the device's hardware safety mechanisms-including lockstep CPU execution, memory ECC/parity, windowed watchdog, and dual-clock comparator-and are documented in TI's functional safety collateral for the F280015x-Q1 family.

How many ADC channels does the F2800156EPHPRQ1 support?

The F2800156EPHPRQ1 supports up to 21 external single-ended ADC input channels, with 9 shared with GPIO pins in the 48-pin HTQFP package. It integrates two independent 12-bit ADCs, each capable of 4 MSPS sampling and equipped with four post-processing blocks (PPB) for hardware-accelerated filtering, averaging, and oversampling-enabling precise current and voltage measurement without CPU load.
