The TMS320F2812GHHQ: The 150 MHz core clock delivers 150 MIPS of deterministic throughput. The 256 KB (128K x 16) on-chip Flash stores the firmware image, and the 18K x 16 RAM handles data buffers.
Buyers should qualify any alternate source for traceability and authenticity, given the part's age and the risk of counterfeit in the surplus market.
179-ball BGA MicroStar — layout and thermal considerations
The TMS320F2812GHHQ is supplied in a 179-LFBGA package (179-BGA MicroStar, 12x12 mm ball array). The fine-pitch BGA requires a multi-layer PCB with microvia or blind-via routing for signal breakout. Supply voltage is 1.81 V to 2 V for the core and I/O, so a dedicated 1.8 V rail is needed alongside the 3.3 V peripheral supply.
Peripheral set for motor control and CAN-based systems
The 16-channel 12-bit ADC with 56 general-purpose I/O pins provides enough analog inputs for three-phase current sensing and resolver feedback. The PWM module with dead-band generation and fault inputs is purpose-built for driving IGBT or MOSFET power stages in motor drives and inverters. The DMA controller offloads data transfers between ADC, memory, and serial peripherals without CPU intervention, preserving MIPS for the control algorithm.
