Texas Instruments F2800156QPMQ1

Overview

F2800156QPMQ1 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 flash (ECC-protected), 36KB RAM (ECC/parity-protected), and ASIL B functional safety certification per ISO 26262. It integrates two 4-MSPS 12-bit ADCs, 14 ePWM channels (4 with 150-ps resolution), one CAN FD/MCAN port, and operates from –40°C to 125°C in a 64-pin LQFP package for motor control in EV inverters.

For engineers reviewing the F2800156QPMQ1 datasheet, F2800156QPMQ1 pinout, F2800156QPMQ1 application, or F2800156QPMQ1 equivalent, key selection criteria include its 100-MHz dual-core lockstep execution, AEC-Q100 Grade 1 qualification, integrated high-resolution PWM and analog signal chain, and support for safety-critical power electronics control in automotive traction inverters and DC/DC converters.

Technical Context

The F2800156QPMQ1 implements dual C28x CPU cores operating in hardware lockstep to enable fault detection for ASIL B compliance without software overhead. Its real-time control subsystem includes TMU and VCRC accelerators, dual 12-bit ADCs with four post-processing blocks each, and ePWM modules with integrated dead-band generation and hardware trip zones.

System-level timing is managed via dual internal 10-MHz oscillators, crystal/external clock input, windowed watchdog, missing-clock detection, and dual-clock comparator (DCC). The device uses 1.2-V core and 3.3-V I/O domains with internal VREG and brownout reset circuitry, supporting multiple low-power modes and zero-pin boot capability.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar real-time control applications.

Compared with F2800157-Q1, F2800156QPMQ1 trades 20 MHz CPU frequency and removes CMPSS ramp-DAC functionality while retaining identical safety certification and peripheral count-making it ideal for cost-sensitive, ASIL B-compliant inverter control where 100 MHz suffices. Against F2800155-Q1, it doubles flash capacity for larger control law storage and future firmware updates without changing PCB layout.

The TMS320F280015x family is part of TI's C2000™ real-time microcontroller portfolio, designed specifically for ultra-low-latency control of power electronics-including inverters, motor drives, and digital power supplies-where deterministic timing and analog integration are critical.

FAQ

What is the maximum operating frequency of the F2800156QPMQ1?

The F2800156QPMQ1 operates at a maximum CPU frequency of 100 MHz. This applies to both C28x cores running in lockstep mode. The frequency is achieved using the on-chip PLL with either internal oscillators or external crystal input. All timing-critical peripherals-including ePWM, ADC, and communication modules-are synchronized to this clock domain, ensuring deterministic real-time behavior for motor control loops.

Does the F2800156QPMQ1 support functional safety certification?

Yes, the F2800156QPMQ1 is ISO 26262 certified up to ASIL B by TÜV SÜD and IEC 61508 certified up to SIL 2. It includes hardware safety mechanisms such as lockstep CPU execution, ECC-protected flash and RAM, memory built-in self-test (MPOST), windowed watchdog timer, and dual-clock comparator (DCC). Documentation supporting system-level safety integration is provided by Texas Instruments for automotive and industrial safety applications.

What package options are available for the F2800156QPMQ1?

The F2800156QPMQ1 is offered exclusively in the 64-pin Low-profile Quad Flatpack (LQFP) package, designated by the "PM" suffix. This package measures 12 mm × 12 mm with a 10 mm × 10 mm body size and is AEC-Q100 Grade 1 qualified. Unlike other members of the F280015x-Q1 family, the F2800156QPMQ1 does not have 80-pin PN, 48-pin PHP, or 32-pin RHB variants-only the PM package is orderable for this specific part number.

How much flash and RAM memory does the F2800156QPMQ1 include?

The F2800156QPMQ1 includes 256 KB (128 KW) of single-bank flash memory with ECC protection and 36 KB (18 KW) of on-chip RAM with ECC/parity protection. The flash is organized into 128 sectors for flexible firmware partitioning and over-the-air update support. The RAM comprises M0-M1 (4 KB) and LS0-LS1 (32 KB) blocks, all accessible by both C28x CPUs and peripherals via the shared memory bus.

Which communication interfaces are integrated into the F2800156QPMQ1?

The F2800156QPMQ1 integrates one Power Management Bus (PMBus) interface, two I2C interfaces, one CAN port, one CAN FD/MCAN port, one SPI port, three UART-compatible SCI interfaces, and one LIN interface. All interfaces support pin multiplexing and share GPIO resources. The MCAN module complies with ISO 11898-1:2015 and supports bit rates up to 5 Mbps, making it suitable for high-speed vehicle network communication in ASIL B systems.
