What are the key features of TMS320C2811PBKA?
- 32-bit fixed-point DSP/DSC core clocked up to 150 MHz with dual internal bus architecture for high-throughput real-time control
- Flexible supply operation: full 150 MHz at core voltage or reduced 135 MHz at 1.8 V supply for power-sensitive applications
- 128-pin PQFP with JTAG boundary scan, enabling thorough board-level test and debug in complex industrial PCB assemblies
What is TMS320C2811PBKA used for?
The TMS320C2811PBKA is purpose-built for real-time control tasks such as AC motor drives, digital power supplies, and servo controllers where 32-bit fixed-point arithmetic at 150 MHz provides the headroom for fast PID loops and complex modulation algorithms. Its on-chip ROM stores boot and math library routines, reducing external flash requirements in cost-sensitive industrial designs. The dual internal bus architecture allows simultaneous instruction fetches and data accesses, sustaining high throughput in demanding multi-axis motion control systems.

Frequently Asked Questions
What is the maximum clock frequency of the TMS320C2811PBKA, and can it run at a lower supply voltage?
The TMS320C2811PBKA operates at up to 150 MHz at its nominal core voltage, and also runs at 135 MHz when powered from a 1.8 V supply. This dual-voltage flexibility lets designers choose between maximum throughput and reduced power dissipation in the same hardware platform, making it practical for battery-assisted industrial controllers or energy-efficient motor drives.
Which motor-control or power-conversion designs benefit most from TMS320C2811PBKA's 32-bit fixed-point DSC core?
The TMS320C2811PBKA is well suited for three-phase AC induction motor drives, BLDC servo controllers, and switch-mode power supply controllers that require fast PID loop execution well under 10 µs. At 150 MHz, a single 32-bit multiply-accumulate completes in one clock cycle (approximately 6.7 ns), giving the control loop ample margin to execute space-vector PWM modulation in real time alongside sensor sampling and fault protection routines.
How does the JTAG boundary scan on TMS320C2811PBKA simplify board-level testing?
The TMS320C2811PBKA includes a full IEEE 1149.1 JTAG boundary-scan interface across all 128 pins of the PQFP package. This allows a board-level tester to shift in test vectors and check interconnect continuity for all I/O lines without applying functional power, dramatically reducing the cost and time of manufacturing test. It also enables in-circuit programming and real-time debugger connections via standard 14-pin JTAG headers.
What package and pin count does TMS320C2811PBKA use, and what does that mean for PCB routing density?
The TMS320C2811PBKA is housed in a 128-pin Plastic Quad Flat Package (PQFP-128, JESD-30 code S-PQFP-G128) with leads on all four sides. A 128-pin PQFP typically uses 0.5 mm lead pitch, so routing 128 signals requires careful impedance-controlled PCB layout with at least 4 signal layers to avoid congestion near the package periphery, especially for high-speed 150 MHz clock and data lines.
