Product details
Overview
F2800157SPN from Texas Instruments is a dual-core C28x real-time microcontroller with lockstep architecture, 120MHz operation, IEEE 754 FPU, TMU, and 256KB ECC-protected flash. 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 automotive motor control and digital power applications.
For engineers reviewing the F2800157SPN datasheet, F2800157SPN pinout, F2800157SPN application, or F2800157SPN equivalent, key selection criteria include dual-lockstep CPU integrity, 120MHz deterministic timing, integrated analog signal chain coupling, and AEC-Q100 Grade 1 qualification for automotive powertrain modules.
Technical Context
The F2800157SPN implements dual TMS320C28x CPUs in hardware lockstep with cycle-by-cycle comparison and error reporting, enabling ASIL B compliance without software overhead. Its real-time control subsystem includes dedicated accelerators: Trigonometric Math Unit (TMU) for fast sine/cosine computation and VCRC engine for CRC-32/16 acceleration in communication stacks.
Peripherals are tightly coupled via crossbars: ADC results feed directly into ePWM trip zones and CMPSS comparators; ePWM outputs synchronize with ADC sampling windows; and GPIO multiplexing supports dynamic reconfiguration of analog/digital I/O across 52 pins (11 shared with analog inputs), supporting flexible signal routing in motor drive and power converter topologies.

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 | AEC-Q100 Grade 1 qualified; identical core/peripheral spec but automotive-qualified package and screening | Required for production automotive ECUs needing ASIL B certification and temperature range –40°C to 125°C | Select F2800157SPN for industrial or non-automotive designs where AEC-Q100 is not mandated |
| TMS320F2800155 | 128 KB flash, same 120 MHz CPU, identical peripherals except reduced ADC channel count (18 vs. 21) and no CMPSS_LITE | Suitable for cost-sensitive motor drives with lower memory and analog I/O requirements | Choose F2800155 when 256 KB flash and full 21-channel ADC are unnecessary to reduce BOM cost |

FAQ
What is the operating temperature range for F2800157SPN?
The F2800157SPN operates across a free-air temperature range of –40°C to 125°C. This specification aligns with industrial and extended commercial environments and is validated per TI's recommended operating conditions. The F2800157SPN does not carry AEC-Q100 qualification, distinguishing it from the automotive-grade F2800157-Q1 variant.
Does F2800157SPN support CAN FD communication?
Yes, F2800157SPN includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) bus port supporting data rates up to 5 Mbps and payloads up to 64 bytes. This interface is fully compliant with ISO 11898-1:2015 and enables high-bandwidth diagnostics and actuator coordination in modern powertrain and industrial networks.
How many high-resolution PWM channels does F2800157SPN provide?
F2800157SPN provides four ePWM channels with high-resolution capability at 150 ps step resolution - specifically ePWM1 and ePWM2. These channels support advanced gate driver control for SiC and GaN power devices, including fine dead-time adjustment and asymmetric waveform generation required in resonant and multilevel topologies.
Is F2800157SPN pin-compatible with other F280015x family members?
F2800157SPN in the 80-pin PN LQFP package shares identical pinout with F2800157-Q1, F2800155, and F2800155-Q1 in the same package option. Pin compatibility is confirmed across all 80-pin variants per TI's Device Comparison table and Package Information section, enabling direct PCB reuse for non-automotive designs.
What security features are implemented in F2800157SPN?
F2800157SPN implements JTAGLOCK to disable debug access, zero-pin boot for secure startup without external configuration pins, and dual-zone security to isolate protected code and data regions.
