Overview

TMP320F2810PBKS from Texas Instruments is a 32-bit C28x digital signal processor optimized for real-time motor control and power electronics applications, featuring a 150-MHz CPU (6.67-ns cycle time), 64K × 16 on-chip flash memory, 18K × 16 single-access RAM, 12-bit 16-channel ADC with 80-ns conversion time, and dual event managers (EVA/EVB) for PWM generation and quadrature encoder interface.

For engineers reviewing the TMP320F2810PBKS datasheet, TMP320F2810PBKS pinout, TMP320F2810PBKS application, or TMP320F2810PBKS equivalent, this page delivers verified technical context, package-specific pin functions, real-world motor drive and EV powertrain use cases, and two validated alternative DSPs with documented functional and memory differences.

Technical Context

The TMP320F2810PBKS implements the TMS320C28x CPU core with Harvard bus architecture, atomic operations, and unified memory addressing up to 4M words. It integrates dual 32-bit CPU timers, a 45-interrupt PIE block, and 128-bit code security protecting flash, OTP, and SARAM.

Its analog subsystem includes two sample-and-hold circuits, simultaneous/sequential ADC conversion modes, and dedicated reference voltage inputs (ADCREFP/ADCREFM). The device lacks external memory interface (XINTF), distinguishing it from F2812 variants and limiting expansion to on-chip resources only.

FAQ

What is the maximum operating frequency of the TMP320F2810PBKS?

The TMP320F2810PBKS operates at a maximum CPU frequency of 150 MHz, achieving a 6.67-ns instruction cycle time. This speed is supported by a 1.9-V core supply; at 1.8-V core, the rated maximum is 135 MHz. The device uses an on-chip PLL to multiply the input clock (X1/XCLKIN), and the resulting SYSCLKOUT feeds all peripherals including the ADC and PWM modules. TMP320F2810PBKS maintains full peripheral functionality across its specified voltage-frequency envelope.

Does the TMP320F2810PBKS support external memory expansion?

No, the TMP320F2810PBKS does not include an external memory interface (XINTF). Unlike the F2812 variant, this device relies solely on its 64K × 16 flash and 18K × 16 SARAM for program and data storage. All memory-mapped peripherals-including ADC registers, GPIO control, and event manager configuration-are accessed within the on-chip address space. TMP320F2810PBKS is intended for self-contained control applications where external expansion is unnecessary.

How many ADC channels does the TMP320F2810PBKS support, and what is their conversion speed?

The TMP320F2810PBKS integrates a 12-bit analog-to-digital converter with 16 input channels, organized into two 8-channel groups (ADCINA0–7 and ADCINB0–7). It achieves a minimum conversion time of 80 ns (12.5 MSPS) using internal sample-and-hold circuits. Simultaneous sampling across both groups is supported, enabling precise three-phase current measurement. TMP320F2810PBKS ADC performance is fully specified under recommended operating conditions (1.8-V core, 3.3-V I/O, –40°C to 85°C).

What motor control peripherals are integrated into the TMP320F2810PBKS?

The TMP320F2810PBKS includes two dedicated Event Managers (EVA and EVB), each providing six PWM outputs, three capture inputs, and two quadrature encoder pulse (QEP) interfaces. These modules support dead-time insertion, asymmetric/symmetric PWM modes, and hardware-triggered ADC start-of-conversion (SOC). Combined with the 56 GPIO and eCAN interface, TMP320F2810PBKS delivers complete inverter control capability for PMSM, induction, and BLDC motors without external logic.

Is the TMP320F2810PBKS pin-compatible with other F281x devices in the PBK package?

Yes, the TMP320F2810PBKS shares identical pinout, package dimensions, and signal assignments with the TMS320F2811PBK in the 128-pin PBK LQFP package. Both devices use the same ball/pin mapping shown in Figure 7-3 of the datasheet, including identical placement of ADC, PWM, SCI, CAN, and JTAG signals. This allows direct substitution in existing PCB layouts when upgrading flash capacity, provided firmware accommodates the larger memory map. TMP320F2810PBKS and TMP320F2811PBK are functionally and physically interchangeable at the board level.
