Product details
Overview
F2800156QPNQ1 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, and 36KB ECC/parity-protected RAM. It integrates two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD port, and functional safety certification up to ASIL B for motor control in EV inverters and DC/DC converters.
For engineers reviewing the F2800156QPNQ1 datasheet, F2800156QPNQ1 pinout, F2800156QPNQ1 application, or F2800156QPNQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 100 MHz CPU frequency (vs. 120 MHz in F2800157-Q1), absence of CMPSS 12-bit DAC, and support for 80-pin LQFP (PN) packaging with 52 GPIOs - critical for high-reliability power electronics design.
Technical Context
The F2800156QPNQ1 implements a dual-core lockstep architecture for fault-detection compliance with ISO 26262 ASIL B, using hardware redundancy without software overhead. Its real-time control subsystem includes TMU and VCRC accelerators to accelerate trigonometric and CRC operations essential for digital power control loops.
It supports multiple clock sources including crystal oscillator, external clock input, and two internal 10MHz oscillators with ExtR resistor tuning. System-level safety features include windowed watchdog timer, missing clock detection, dual-clock comparator (DCC), and memory power-on self-test (MPOST) for flash and RAM integrity verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800157-Q1 | 120 MHz dual-core, includes CMPSS with 12-bit DAC, same 256KB flash and 36KB RAM. | Supports advanced analog comparators for overcurrent protection with dynamic ramp generation - required for high-fidelity fault response in traction inverters. | Select when higher CPU performance and integrated comparator DAC are needed; pin-compatible but requires updated timing constraints in PCB layout. |
| TMS320F2800155-Q1 | 100 MHz dual-core, 128KB flash, 36KB RAM, no CMPSS 12-bit DAC, same peripheral set otherwise. | Targeted at cost-sensitive applications where reduced firmware footprint suffices - e.g., auxiliary DC/DC or low-power pump controllers. | Select when flash capacity can be reduced by 50% and comparator DAC is not required; shares identical package and pinout with F2800156QPNQ1. |
Compared with F2800157-Q1, F2800156QPNQ1 trades 20 MHz CPU speed and CMPSS DAC capability for identical ASIL B certification and package compatibility; compared with F2800155-Q1, it doubles flash capacity while retaining the same frequency and safety grade - making it optimal for complex OBC or inverter firmware with safety-critical diagnostics.

FAQ
What is the maximum operating frequency of the F2800156QPNQ1?
The F2800156QPNQ1 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.

Does the F2800156QPNQ1 include a 12-bit comparator subsystem (CMPSS) with DAC?
No, the F2800156QPNQ1 does not include the CMPSS with 12-bit DAC. Per the Device Comparison table, CMPSS (with dynamic DAC) is marked "–" for F2800156-Q1, unlike F2800157-Q1 which includes one. It does support three CMPSS_LITE modules with 9.5-bit effective reference DACs for basic overvoltage/overcurrent detection.
Which packages are supported by the F2800156QPNQ1?
The F2800156QPNQ1 is offered in four package options: 80-pin LQFP (PN), 64-pin LQFP (PM), 48-pin HTQFP (PHP), and 32-pin VQFN (RHB). The "QPNQ1" suffix explicitly denotes the 80-pin LQFP (PN) package with AEC-Q100 Grade 1 qualification and –40°C to 125°C ambient temperature rating.
Is the F2800156QPNQ1 certified for functional safety standards?
Yes, the F2800156QPNQ1 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 comparison, memory ECC, watchdog timers, and diagnostic firmware libraries provided in C2000Ware Safety Software Library.
How many GPIO pins does the F2800156QPNQ1 provide in the 80-pin LQFP package?
In the 80-pin LQFP (PN) package, the F2800156QPNQ1 provides 52 individually programmable GPIO pins. Of these, 11 are shared with analog inputs (AIO), and 4 are shared with JTAG signals (TDI, TDO, X1, X2), which may be repurposed as GPIO when cJTAG or internal oscillator modes are enabled.
