FAE Expert Insights
"The FCP32C335 has become my top recommendation for customers looking to replace TMS320F28335. I've supported multiple successful migrations where customers reported identical performance with significant cost savings. The HRPWM is genuinely impressive - at 150ps resolution, you can achieve extremely fine control for precision servo applications. I recently helped a customer implement FOC for a 5kW servo drive, and the FCP32C335 handled the control loop with plenty of headroom. The rich peripheral set means you often don't need external components - the integrated ADC and comparators are sufficient for many designs. Code migration from TI C2000 is straightforward; most projects need only minor header file changes. I recommend the LQFP-100 package for most applications unless you need the extra GPIO of the LQFP-176."

How do I select the appropriate package for FCP32C335?
FCP32C335 is available in LQFP-176 and LQFP-100 packages. The LQFP-176 offers 88 GPIO pins and is suitable for complex applications requiring many I/Os like multi-axis servo drives or systems with extensive peripheral connections. The LQFP-100 provides a reduced pin count with essential peripherals and is ideal for space-constrained designs or simpler applications. Both packages offer the same core performance and peripheral functionality. The LQFP-100 is more cost-effective and easier to layout on 2-layer PCBs. For most motor control applications, the LQFP-100 is sufficient.
Choose LQFP-100 for most applications; select LQFP-176 only if you need maximum GPIO count. Contact us for package selection guidance.
What is the ADC performance of FCP32C335?
FCP32C335 features a 12-bit SAR ADC with 16 input channels. The ADC supports simultaneous sampling of two channels, which is essential for motor current measurement. Conversion time is approximately 80ns per channel at 12.5MHz ADC clock. The ADC can be triggered by PWM events for synchronized sampling in motor control applications. Input range is 0-3.3V with built-in sample-and-hold. The ADC includes offset and gain calibration features. For high-precision applications, the 12-bit resolution provides 4096 steps, sufficient for most industrial control requirements. Funcience provides ADC driver code and calibration routines.
The 12-bit ADC is suitable for most motor control and power applications. Contact us for ADC configuration examples.
Does FCP32C335 support real-time debugging?
Yes, FCP32C335 supports real-time debugging through the JTAG interface. The chip is compatible with standard JTAG debuggers including XDS100 and XDS200 series. Real-time mode allows debugging without stopping the CPU, which is crucial for motor control applications where stopping would cause system failure. Code Composer Studio provides full debugging support including breakpoints, watch variables, and real-time data exchange. Flash programming is supported through JTAG. Funcience provides debugger configuration files and debugging guides.
