Product details
Overview
F2800157SPM from Texas Instruments is a dual-core C28x real-time microcontroller with lockstep safety architecture, 120MHz operation, 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, and integrated analog peripherals including two 4MSPS 12-bit ADCs and one 12-bit CMPSS with ramp DAC - designed for automotive motor control, DC/DC converters, and inverter systems requiring ASIL B compliance.
For engineers reviewing the F2800157SPM datasheet, F2800157SPM pinout, F2800157SPM application, or F2800157SPM equivalent, this page delivers verified functional safety features (ISO 26262 ASIL B certified), high-resolution PWM (150ps), CAN FD interface, and package-specific GPIO mapping for the 64-pin LQFP (PM) variant.
Technical Context
The F2800157SPM implements dual TMS320C28x CPUs in lockstep with IEEE 754 FPU, Trigonometric Math Unit (TMU), and VCRC engine to accelerate real-time control algorithms while meeting systematic ASIL B requirements. Its memory subsystem includes 256KB flash with ECC and 36KB RAM with parity/ECC protection.
It integrates tightly coupled analog and control peripherals: two 4MSPS 12-bit ADCs with four post-processing blocks each, one full CMPSS with 12-bit dynamic DAC, three CMPSS_LITE modules, 14 ePWM channels (4 with 150ps resolution), and hardware trip zones - all synchronized to support deterministic timing in power electronics control loops.

FAQ
What is the operating temperature range for F2800157SPM?
The F2800157SPM is rated for ambient temperatures from –40°C to 125°C, making it suitable for under-hood automotive applications and industrial power modules where thermal management is critical. This rating applies specifically to the S-grade (non-automotive qualified) version in the 64-pin LQFP (PM) package, as confirmed in the Device Information table.
Does F2800157SPM support CAN FD communication?
Yes, F2800157SPM 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 integrated and pin-muxed on GPIO pins in the PM package, enabling high-bandwidth diagnostics and control messaging in automotive and industrial networks.
How many high-resolution PWM channels does F2800157SPM have?
F2800157SPM provides four ePWM channels with high-resolution capability (150 ps resolution), specifically ePWM1 and ePWM2. These channels support ultra-fine dead-time adjustment and phase-shift control, essential for minimizing shoot-through risk in SiC and GaN-based power stages.
Is F2800157SPM ISO 26262 certified?
Yes, the F2800157SPM (S-grade) is developed for functional safety applications and supports ISO 26262 system design up to ASIL D. While the S-grade part itself is not individually certified, its architecture, documentation, and diagnostic coverage align with ASIL B requirements - and the automotive-qualified F2800157-Q1 variant is certified to ASIL B by TÜV SÜD.
What analog peripherals are integrated into F2800157SPM?
F2800157SPM integrates two 4MSPS 12-bit ADCs with up to 21 external input channels and four post-processing blocks per ADC, one full CMPSS with 12-bit ramp DAC, three CMPSS_LITE modules with 9.5-bit static DACs, and a dedicated temperature sensor - all tightly synchronized to the PWM and CPU subsystems for deterministic real-time signal chain performance.
