FAQ

What is the maximum operating frequency of the TMS320F28232PTPS?

The TMS320F28232PTPS operates at a maximum CPU frequency of 100 MHz, corresponding to a 10-ns instruction cycle time. This speed is achieved at 1.9-V core voltage and supports deterministic execution of real-time control algorithms in demanding applications such as motor drives and inverters. The device does not include a floating-point unit, distinguishing it from the F2833x series.

Does the TMS320F28232PTPS include a floating-point unit (FPU)?

No, the TMS320F28232PTPS does not include an IEEE 754 single-precision floating-point unit. It uses the fixed-point C28x CPU core. For FPU capability in the same family, engineers should consider the TMS320F28332PTPS or other F2833x devices. The TMS320F28232PTPS relies on optimized fixed-point math libraries for control law implementation.

What package type and thermal specifications apply to the TMS320F28232PTPS?

The TMS320F28232PTPS uses the HLQFP-176 (PTP) package: a thermally enhanced low-profile quad flatpack measuring 24.0 mm × 24.0 mm. It is rated for operation from –40°C to 125°C and features dedicated thermal pad and optimized copper pour recommendations in TI's PCB layout guidelines to manage junction temperature in high-power applications.

How many PWM and HRPWM channels does the TMS320F28232PTPS support?

The TMS320F28232PTPS supports six enhanced PWM (ePWM) modules, each providing complementary A/B outputs. Four of these (ePWM1–4) include high-resolution PWM (HRPWM) capability with 150-ps minimum edge placement resolution-enabling precise dead-time control and advanced modulation techniques in SiC/GaN-based power stages.

What ADC performance characteristics are specified for the TMS320F28232PTPS?

The TMS320F28232PTPS integrates a 12-bit analog-to-digital converter with 16 input channels, dual 8-channel multiplexers, and two sample-and-hold circuits. It achieves 12.5 MSPS throughput with 80-ns conversion time and supports both single and simultaneous sampling modes-critical for synchronized current and voltage acquisition in three-phase motor control.
