Technical Context

The TMS320F2810PBKA implements the TMS320C28x CPU core with Harvard architecture, atomic instruction execution, and unified memory addressing up to 4M words. It integrates two independent Event Managers (EVA and EVB) supporting 16 PWM outputs, 6 capture/QEP channels, and trip-zone protection for IGBT gate drivers.

Its system-level timing architecture includes an on-chip oscillator, PLL-based clock module (configurable 1.8-V/1.9-V core at 135/150 MHz), watchdog timer, and Peripheral Interrupt Expansion (PIE) block servicing 45 peripheral interrupts - all synchronized to the 150-MHz SYSCLKOUT derived from the PLL.

FAQ

What is the maximum operating frequency of the TMS320F2810PBKA?

The TMS320F2810PBKA operates at a maximum CPU frequency of 150 MHz, achieving a 6.67-ns instruction cycle time. This speed is supported at 1.9-V core voltage under recommended operating conditions. The device includes an integrated PLL that multiplies the input clock (from crystal or external source) to generate the required SYSCLKOUT, and its performance is validated across the full industrial temperature range (–40°C to 85°C).

Does the TMS320F2810PBKA include an external memory interface?

No, the TMS320F2810PBKA does not include an external memory interface. Unlike the F2812 variants (e.g., PGF or GHH packages), the PBK package omits the XINTF signals (XA[0–18], XD[0–15], XZCSn, XRD, XWE, etc.). Its memory subsystem relies solely on on-chip resources: 64K × 16 flash, 18K × 16 SARAM, 4K × 16 boot ROM, and 1K × 16 OTP.

How many PWM outputs does the TMS320F2810PBKA support?

The TMS320F2810PBKA supports 16 dedicated PWM outputs via its two integrated Event Managers (EVA and EVB). Each module provides eight PWM channels with programmable frequency, duty cycle, dead-band, and synchronization capabilities. These outputs are directly mapped to pins such as PWM1–PWM12 and associated complementary pairs, enabling three-phase inverter control with hardware fault protection.

What ADC resolution and speed does the TMS320F2810PBKA provide?

The TMS320F2810PBKA integrates a 12-bit analog-to-digital converter with 16 input channels, capable of 80-ns conversion time (12.5 MSPS). It features two sample-and-hold circuits, dual 8-channel multiplexers, and supports both single and simultaneous sampling modes - critical for synchronized current measurement in motor phase legs.

Is the TMS320F2810PBKA pin-compatible with other F281x devices in the PBK package?

Yes, the TMS320F2810PBKA shares identical pinout and package dimensions (128-pin LQFP, PBK) with the TMS320F2811PBK. Both devices use the same signal mapping, power/ground distribution, and thermal pad layout. However, the F2811 includes 128K × 16 flash versus 64K × 16 in the F2810, and both lack the external memory interface present in F2812 variants.
