90 MHz C28x core — real-time loop timing
The TMS320F28064UPFPS: The 32-bit C28x core runs at 90 MHz.
128 KB Flash — firmware budget for field updates
Program memory is 128 KB of Flash, organized as 64K x 16. That holds a complete motor-control firmware stack with CANopen or Modbus RTU comms, plus room for a bootloader for in-field updates. The 50K x 16 RAM covers the variable arrays and buffer frames without spilling to external memory.
Peripheral set — PWM, ADC, and comms in one chip
Lifecycle and sourcing — verify before BOM freeze
This contradiction means the buyer should confirm current availability and lead time before committing the BOM line.
Supply and mounting
Core supply is 1.71 V to 1.995 V.
