TMS320F28075PTPQ - 120MHz C2000 C28x MCU, 512KB Flash | TI
MPN： TMS320F28075PTPQ ✓ 啟用中TMS320F28075PTPQ 概覽
This device belongs to the C2000 microcontroller family, a real-time control MCU platform engineered for digital power, motor control, and industrial sensing. C2000 devices combine a deterministic C28x DSP core with control-oriented peripherals such as high-resolution PWMs, 12-bit ADCs, sigma-delta filter modules (SDFM), and the Control Law Accelerator (CLA) for parallel signal-chain processing. Within the C2000 hierarchy, the F2807x sits in the Piccolo series above F28004x and below F2837x/F2838x dual-core devices.
Key differentiating features include 120 MHz C28x core with IEEE-754 single-precision FPU, Trigonometric Math Unit (TMU) accelerating sin/cos/atan and a parallel Control Law Accelerator (CLA) effectively doubling real-time throughput. Integrated SDFM (Sigma Delta Filter Module) accepts isolated shunt current/voltage signals, while the 512 KB Flash with ECC supports functional-safety firmware patterns and field firmware updates. The 176-pin HLQFP (PTP) package provides ample GPIO and analog channel count for multi-axis motor control or multi-loop digital power stages.
The silicon uses a 40 nm process with on-chip 1.2 V core LDO and 3.3 V I/O; package construction is a wire-bond HLQFP with thermal pad. The C2000 platform is supported by TI's Code Composer Studio (CCS) and MotorControl SDK, accelerating real-time control firmware deployment. The -Q1 suffix (TPSuffix PTPQ encodes automotive grade) plus the device's functional-safety documentation make it suited to ISO 26262-oriented designs.
Typical applications include EV traction inverters and onboard chargers, industrial servo drives and field-oriented motor control (FOC), solar/photovoltaic string inverters and DC/DC converters, digital power supplies with PFC + LLC control loops, and automotive ADAS sensor fusion pre-processors. The CLA plus SDFM is particularly effective for multi-shunt phase current sampling in FOC firmware.
A design consideration: the F28075 requires a clean 3.3 V supply and decoupling network at every VDD/VSS pair; the HLQFP's exposed thermal pad must be soldered to a continuous copper pour to meet the 120 MHz power dissipation. Always confirm specific peripheral availability against the device-specific datasheet before committing to pinout.

設計說明
Decouple every VDD/VSS pair with a 100 nF ceramic cap placed within 3 mm of each pin pair, plus a 4.7 uF bulk cap per VDD rail. The F28075's internal 1.2 V LDO is sensitive to load transients above 50 mA/us; insufficient bulk capacitance causes core voltage droop and potential reset. Per TI C2000 hardware design guide, do not share decoupling between adjacent VDD pairs.
Solder the exposed thermal pad (EP) of the 176-HLQFP to a continuous copper pour on the top layer, stitched with thermal vias to inner ground planes. The HLQFP is a wire-bond package, so thermal pad solder quality directly impacts the junction-to-ambient thermal resistance. At full 120 MHz operation with all peripherals enabled, expect 200-500 mW dissipation requiring at least 1 sq-in of 2-oz copper for safe operation up to 85C ambient.
Route all ADC analog inputs (ADCINAx/ADCINBx) with differential pairs guarded by ground traces; keep digital switching signals (PWM outputs) at least 3 trace-widths away to minimize crosstalk. Per TI's C2000 PCB design guide, use a 4-layer PCB with a dedicated ground plane for best ADC SNR; 2-layer boards typically lose 3-5 ENOB. Place the crystal/oscillator within 5 mm of the X1/X2 pins and guard with a ground ring.
Confirm the boot-mode GPIO pin pull-up/pull-down configuration matches your firmware boot source before PCB fabrication - misconfigured boot pins cause 'brick dead' parts that require JTAG recovery. Also note that the F28075 (vs F28076/F2837x) has fewer DMA channels and lacks USB; verify peripheral availability against the device-specific datasheet section 1 before committing to pinout, as the datasheet covers the entire F2807x family.
The 12-bit ADC achieves best performance when sampling synchronous to PWM edges - use the SOC (start-of-conversion) signals driven by PWM modules rather than software triggering. The SDFM channels accept isolated sigma-delta bitstreams up to 20 MHz; route these traces as matched-length differential pairs and terminate per the modulator datasheet. According to TI's C2000 reference designs, improper SDFM clock routing is the most common cause of failed shunt current sensing.
