Product details
Overview
F2800157EPHPQ1 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 256KB 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 per ISO 26262 for motor control in electric powertrain systems.
For engineers reviewing the F2800157EPHPQ1 datasheet, F2800157EPHPQ1 pinout, F2800157EPHPQ1 application, or F2800157EPHPQ1 equivalent, this page delivers verified technical context, package-specific pin mapping, functional safety design implications, and validated alternative options for automotive power electronics development.
Technical Context
The F2800157EPHPQ1 implements a dual-core lockstep architecture with hardware-level redundancy checking, enabling ASIL B compliance without significant software overhead. Its real-time control subsystem includes dedicated accelerators: TMU for fast sine/cosine computation and VCRC for efficient CRC generation-both critical for closed-loop motor control and communication integrity.
It features tightly coupled analog and PWM subsystems: two 4MSPS ADCs with four post-processing blocks each, one 12-bit CMPSS with ramp DAC, three 9.5-bit CMPSS_LITE modules, and 14 ePWM channels with integrated dead-band and hardware trip zones-optimized for 3-phase inverter, PFC, and multilevel power topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800155-Q1 | 128KB flash, same 120MHz dual-core lockstep, identical PHP package and peripheral set except reduced flash size. | Suitable for less complex motor control firmware with smaller code footprint; lacks headroom for future feature expansion or OTA updates. | Select when cost sensitivity outweighs need for firmware scalability and diagnostic logging capacity. |
| TMS320F2800153-Q1 | 64KB flash, same PHP package, but only 9 ADC channels and no HRPWM capability-no 150ps resolution ePWM channels. | Limited to lower-performance applications such as HVAC blower control or seat motor actuation where sub-ns timing is unnecessary. | Choose only for cost-constrained, non-safety-critical industrial or body electronics where ASIL B is not required. |
Compared with F2800157EPHPQ1, the F2800155-Q1 retains full functional safety and timing capability but trades flash capacity for cost, while the F2800153-Q1 sacrifices HRPWM, ADC channel count, and safety-certified memory protection-making it unsuitable for traction or steering applications.
