150 MHz C28x fixed-point DSP — real-time control engine
It integrates 128 KB of on-chip Flash program memory (64K x 16) and 18K x 16 of RAM, with a 16-channel 12-bit ADC, CAN, SPI, SCI, and McBSP serial interfaces.
Sourcing reality — EOL hot, last-time-buy channel
128-LQFP package — board-fit considerations
The 128-LQFP package (14x14 mm body) is a surface-mount footprint common in industrial control PCBs. The 56 general-purpose I/O pins provide enough flexibility for parallel sensor interfaces and PWM outputs.
Peripheral set for motor-drive and power-conversion designs
The on-chip peripherals are tailored for real-time control: a 16-channel 12-bit ADC captures three-phase currents and voltages simultaneously; the PWM module with dead-band generation drives IGBT or MOSFET gates directly; CAN and SCI interfaces handle fieldbus communication with a host controller or drive network. DMA offloads the C28x core during high-speed data transfers, and the watchdog timer provides fail-safe supervision in safety-critical applications.
