FAE Expert Insights
"The FCP32C334 is my recommendation for cost-sensitive motor control applications. While it doesn't have the HRPWM of the FCP32C335, the standard PWM at 100MHz is still excellent for most VFD and pump control applications. I've used this chip in several fan control projects where the 12 PWM channels are sufficient for 3-phase control with some I/O to spare. The 256KB Flash is adequate for most control algorithms, and the 12-channel ADC handles current and voltage sensing well. The LQFP-100 package is easy to work with and fits on 2-layer PCBs. For applications not requiring extreme precision, the FCP32C334 offers significant cost savings while maintaining reliable performance. I recommend it for high-volume consumer and industrial products where cost is critical."

Frequently Asked Questions
When should I choose FCP32C334 over FCP32C335?
Choose FCP32C334 when your application doesn't require the advanced features of FCP32C335. The FCP32C334 is suitable for: Basic VFD drives for fans and pumps where standard PWM resolution is sufficient. Cost-sensitive high-volume products where every dollar matters. Applications with simpler control algorithms that don't need 150MHz processing. Systems where 256KB Flash is adequate for the application code. Projects that don't require HRPWM precision. The FCP32C334 offers about 30-40% cost savings compared to FCP32C335 while maintaining reliable performance for standard industrial applications.
Select FCP32C334 for cost-sensitive applications. Upgrade to FCP32C335 if you need HRPWM or higher processing power.
What is the PWM resolution of FCP32C334?
FCP32C334 uses standard PWM with resolution determined by the system clock and switching frequency. At 100MHz system clock with 10kHz switching frequency, the PWM resolution is approximately 10,000 steps (100MHz/10kHz). This is sufficient for most VFD and pump control applications. For comparison, FCP32C335's HRPWM provides 150ps resolution which is about 655,000 steps at the same frequency. If your application requires extremely smooth motor operation or precise current control, consider upgrading to FCP32C335. For standard industrial drives, FCP32C334's PWM resolution is adequate.
FCP32C334 PWM is suitable for standard drives. Choose FCP32C335 HRPWM for precision servo applications.
Can FCP32C334 handle 3-phase motor control?
Yes, FCP32C334 is fully capable of 3-phase motor control. With 12 PWM channels, you have sufficient outputs for 3-phase inverter control (6 channels) plus additional PWMs for other functions. The 100MHz processing power is adequate for FOC (Field Oriented Control) algorithms at typical switching frequencies of 5-10kHz. The 12-channel ADC allows measurement of three-phase currents and DC bus voltage. Many successful VFD and servo drive designs use the FCP32C334 for 3-phase motor control. Funcience provides 3-phase motor control reference designs and example code.

What is the Flash programming method for FCP32C334?
FCP32C334 Flash can be programmed through multiple methods: JTAG interface using standard C2000 debuggers like XDS100. Serial port programming for production environments. CAN bootloader for field updates. Funcience provides Flash programming tools and utilities. The Flash supports at least 10,000 erase/program cycles with 10-year data retention. Programming time is approximately 1-2 seconds for the full 256KB Flash. For production, gang programmers or automated test equipment can be used. Funcience provides programming algorithms and support for major programming equipment.
Use JTAG for development, serial or CAN for production programming. Contact us for programming tools and production support.
Does FCP32C334 support code migration from other C2000 devices?
Yes, FCP32C334 supports code migration from other C2000 devices including TMS320F28035 and TMS320F28034. The C28x core is code-compatible across the family. Peripheral register maps are similar, requiring only minor code adjustments. Funcience provides migration guides detailing differences and required changes. Most control algorithms and driver code can be reused with minimal modification. The main considerations are memory size differences and peripheral availability. Customers typically achieve code migration within 2-4 weeks depending on application complexity.
