TMS320F2800157-Q1 Overview
A C2000 real-time microcontroller is a specialized MCU family from TI designed for closed-loop control applications such as motor drives, power converters, and industrial automation. These devices combine a high-performance CPU with dedicated control peripherals (PWMs, ADCs, comparators) to execute control algorithms with deterministic timing.
Key features include 120 MHz C28x CPU, 256 KB flash, 256 KB RAM, 4 high-resolution PWM channels, 12-bit ADC with 3.46 MSPS, CAN-FD interface, and lockstep ASIL B functional safety capability for automotive Grade 0 and Grade 1 operation. The device supports up to 2MB of external memory via XINTF.
Architecture: The C28x core uses a modified Harvard architecture with unified memory map, executing up to 6 instructions per cycle. The CLA co-processor offloads math-intensive control loops. The HRPWM block provides 150 ps resolution, enabling precise power-stage control in interleaved converters.
Typical applications include automotive traction inverter control, DC-DC converters, on-board chargers (OBC), and integrated starter-generators. The CAN-FD interface supports vehicle network integration, while the functional safety features enable ASIL B certification in safety-critical systems.
Design consideration: For CAN-FD connectivity, use appropriate isolation - the ISO6442-Q1 digital isolator (available on XAIPART) pairs well. Ensure decoupling capacitors (0.1 uF and 10 uF) on all VDD pins for reliable 120-MHz operation.

- Can-FD with functional safety (vs TMS320F2800154-Q1)
Design Notes
Connect a 0.1 uF ceramic capacitor and 10 uF tantalum capacitor on each VDDIO pin. Use a 1.2 V regulator for the VDD core with 0.1 uF bypass. Separate analog and digital grounds, joining them at a single point near the MCU. This reduces noise effects on ADC measurements.
Place the crystal oscillator within 20 mm of XTAL pins with short traces. Route CAN-FD differential pairs with 120-ohm impedance and length matching. Keep high-frequency PWM traces away from analog input signals to prevent coupling into ADC channels.
Ensure XRS reset pin has a 10 kOhm pull-up to VDDIO and a 1 uF capacitor to ground for reliable power-on reset. For CAN-FD communication, use the ISO6442-Q1 isolator to protect the transceiver. Avoid floating unused input pins - connect them to appropriate logic levels.
Compliance Information
