Migrating from TI C2000 to other MCU

If you’re currently using TI C2000 MCUs (real-time control, fast ADCs, precise PWMs) and wish to migrate to another manufacturer, the key is to find MCUs with similar performance, timing determinism, analog performance, and control-centric peripherals.

Let’s go step-by-step

1. What Makes C2000 Unique

Before choosing alternatives, note what defines a C2000:

Deterministic real-time core (C28x CPU)
High-speed ADCs (up to 4 MSPS)
High-resolution PWM (HRPWM)
Dedicated control peripherals (comparators, DACs, CLA co-processor)
Low interrupt latency, designed for motor drives, PFC, inverters

So any replacement MCU must handle tight control loops (10–50 µs) and precise PWM timing.

2. Closest Alternatives by Manufacturer

STMicroelectronics – STM32G4 / STM32F3 / STM32H7

Closest general alternative to C2000 for motor control and power conversion.

Series	Key Features	Remarks
STM32G4	170 MHz Cortex-M4F, 5 MSPS ADC, advanced PWM timers	Designed for digital power & motor control; very good match to Piccolo C2000
STM32F3	72–144 MHz Cortex-M4, dual ADC, comparators, DACs	Lower cost, less capable
STM32H7	400 MHz Cortex-M7, high performance for complex control	Overkill for basic control but good for high-power or multi-axis

Software Ecosystem: STM32CubeIDE + STM32 Motor Control SDK
Strength: Widely available, rich development tools, low cost

Microchip – dsPIC33 / PIC32MK

Microchip’s control-optimized MCU line.

Series	Key Features	Remarks

MPLAB X / MCC offer digital power and motor libraries similar to TI’s controlSUITE

Strength: Excellent for digital power (PFC, LLC), motor drives; good long-term availability.
Feel: Very close to C2000 in control performance and peripherals.

Infineon – XMC4000 / AURIX TC3xx

Strong in industrial control and automotive.

Series	Key Features	Remarks
XMC4400/4800	Cortex-M4F, 12-bit 2 MSPS ADC, advanced CCU8/CCU4 timers	Designed for motor control & inverters
AURIX TC3xx	TriCore CPU, 200–300 MHz, safety-oriented (ASIL)	For automotive / high-power digital control

i.MX RT1010–1170	Very high-performance Cortex-M7, up to 1 GHz	Best if you need communication + control in one chip

Strength: Strong in automotive, safety-certified, robust CAN/LIN/FlexRay.
Weakness: PWM and ADCs not as tightly integrated as C2000 or dsPIC.

Renesas – RX24T / RX26T / RA6T

Renesas’ dedicated motor-control MCU line.

Series	Key Features	Remarks
RX24T / RX26T	32-bit RX core, high-res PWM, fast ADC	Designed for 3-phase inverter and digital power
RA6T1	Cortex-M4, enhanced motor control timer	Newer architecture, very efficient

Strength: Used in industrial drives, stable Japanese quality.
Weakness: Smaller ecosystem, limited community support compared to STM32.
