Texas Instruments TMS320F2810PBKQR

Overview

TMS320F2810PBKQR 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, 64K × 16 on-chip flash memory, 18K × 16 single-access RAM (SARAM), 12-bit 16-channel ADC with 80-ns conversion time, and dual event managers (EVA/EVB) for PWM generation and quadrature encoding.

For engineers reviewing the TMS320F2810PBKQR datasheet, TMS320F2810PBKQR pinout, TMS320F2810PBKQR application, or TMS320F2810PBKQR equivalent, key selection criteria include its 128-pin LQFP (PBK) package, 1.8-V/1.9-V core voltage operation at 135/150 MHz, eCAN and SPI/SCI/McBSP serial interfaces, and code-security module supporting 128-bit key lock for firmware protection.

Technical Context

The TMS320F2810PBKQR implements the TMS320C28x CPU core with Harvard bus architecture, atomic operations, and unified memory programming model enabling efficient C/C++ execution. It integrates two independent Event Managers (EVA and EVB) each with three 16-bit GP timers, 16 PWM outputs, six capture/QEP inputs, and trip-zone protection logic for IGBT gate drive safety.

Its system-level timing architecture includes an on-chip oscillator, PLL-based clock module supporting SYSCLKOUT up to 150 MHz, programmable low-power modes (IDLE/STANDBY/HALT), and Peripheral Interrupt Expansion (PIE) block managing 45 peripheral interrupts across nine groups - critical for deterministic response in closed-loop motor control and power converter regulation.

FAQ

What is the maximum operating frequency of the TMS320F2810PBKQR CPU core?

The TMS320F2810PBKQR CPU core operates at up to 150 MHz, achieving a 6.67-ns instruction cycle time. This frequency is supported with a 1.9-V core supply voltage; at 1.8-V core voltage, the maximum rated frequency is 135 MHz. The device uses an internal PLL to multiply the input clock from the on-chip oscillator or external source, and the SYSCLKOUT frequency is fully programmable within these limits. All timing specifications in the datasheet assume operation at the rated voltage/frequency combination.

Does the TMS320F2810PBKQR support external memory expansion?

No, the TMS320F2810PBKQR does not support external memory expansion. Unlike the TMS320F2812 variant, it lacks the External Interface (XINTF) module and associated address/data bus pins. Its memory subsystem consists solely of on-chip resources: 64K × 16 flash, 18K × 16 SARAM, 4K × 16 boot ROM, and 1K × 16 OTP ROM. This design targets self-contained control applications where all firmware and runtime variables fit within internal memory.

How many PWM outputs does the TMS320F2810PBKQR provide, and what is their resolution?

The TMS320F2810PBKQR provides 16 dedicated PWM outputs via its two Event Managers (EVA and EVB). Each PWM channel supports 16-bit timer resolution with programmable period and duty cycle registers. The hardware supports complementary PWM pairs with programmable dead-time insertion, edge-aligned or center-aligned modes, and synchronization across multiple timers - essential for 3-phase inverter gate driving. No additional PWM generation is possible through GPIO bit-banging due to deterministic timing requirements.

What serial communication interfaces are integrated into the TMS320F2810PBKQR?

The TMS320F2810PBKQR integrates four serial communication interfaces: one enhanced Controller Area Network (eCAN) module compliant with ISO 11898-1, two Serial Communications Interfaces (SCI-A and SCI-B) implementing standard UART functionality, one Serial Peripheral Interface (SPI), and one Multichannel Buffered Serial Port (McBSP). These interfaces operate at 3.3-V I/O levels and support independent baud rates, enabling concurrent communication with gate drivers, sensors, host MCUs, and diagnostic tools without resource contention.

Is the TMS320F2810PBKQR pin-compatible with other devices in the F281x family?

The TMS320F2810PBKQR shares the same 128-pin PBK LQFP package and pinout with the TMS320F2811PBK, enabling direct PCB compatibility between these two variants. However, it is not pin-compatible with the 176-pin PGF or 179-ball BGA packages used by the F2812 series. Functional differences - such as flash size (64K vs. 128K) and absence of XINTF - must be verified in schematic and firmware design, even when footprint matches.
