Texas Instruments TMS320F2810PBKS

Overview

TMS320F2810PBKS from Texas Instruments is a 150-MHz C28x-core digital signal processor optimized for real-time motor control and power electronics applications, featuring 64K × 16 on-chip flash, 18K × 16 single-access RAM, 12-bit 16-channel ADC with 80-ns conversion time, dual event managers (EVA/EVB), and eCAN interface - deployed in industrial inverters and EV traction control units.

For engineers reviewing the TMS320F2810PBKS datasheet, TMS320F2810PBKS pinout, TMS320F2810PBKS application, or TMS320F2810PBKS equivalent, this page delivers verified package mapping (128-pin LQFP PBK), confirmed peripheral register compatibility with F281x family, validated security key lock implementation, and precise ADC timing constraints per SPRS174V Rev. V.

Technical Context

The TMS320F2810PBKS implements a Harvard-architecture 32-bit C28x CPU with atomic instruction execution, 4M linear address space, and little-endian data organization. It integrates two independent Event Managers supporting 16 PWM outputs, 6 capture/QEP inputs, and trip-zone protection for gate-driver interfacing.

Its system-level timing relies on an on-chip oscillator with PLL-based clock module generating SYSCLKOUT up to 150 MHz (6.67-ns cycle time), while low-power modes (IDLE/STANDBY/HALT) enable dynamic peripheral clock gating. The 12-bit ADC uses dual sample-and-hold circuits and supports simultaneous sampling across two 8-channel multiplexers.

FAQ

What is the maximum operating frequency and core voltage for TMS320F2810PBKS?

The TMS320F2810PBKS operates at a maximum frequency of 150 MHz with a 1.9-V core supply voltage. At 135 MHz, it supports 1.8-V core operation. Both configurations maintain full peripheral functionality and are validated across the full –40°C to 125°C temperature range specified for the Q-grade TMS320F2810PBKS device.

Does TMS320F2810PBKS include an external memory interface (XINTF)?

No, the TMS320F2810PBKS does not include the external memory interface (XINTF). This feature is exclusive to the TMS320F2812 variants (e.g., TMS320F2812PGF). The TMS320F2810PBKS relies solely on its on-chip 64K × 16 flash and 18K × 16 SARAM, making it suitable for self-contained control applications without external memory expansion needs.

What ADC performance specifications apply to TMS320F2810PBKS?

The TMS320F2810PBKS integrates a 12-bit successive-approximation ADC with 16 input channels (two 8-channel groups), 80-ns conversion time (12.5 MSPS), dual sample-and-hold circuits, and support for both single and simultaneous sampling modes. These specifications are identical across all F281x devices, including the TMS320F2810PBKS.

Is TMS320F2810PBKS AEC-Q100 qualified?

Yes, the TMS320F2810PBKS is AEC-Q100 qualified for Grade 1 (–40°C to 125°C) operation. This qualification applies specifically to the Q-grade variant denoted by the "Q" suffix in the part number, confirming reliability for automotive powertrain and chassis control applications per the AEC-Q100 standard.

How does the code security module function on TMS320F2810PBKS?

The TMS320F2810PBKS implements a 128-bit code-security key/lock that protects on-chip flash, OTP ROM, and L0/L1 SARAM from unauthorized read access. Once enabled, the security lock prevents JTAG-based firmware extraction and debug access, effectively blocking reverse engineering of proprietary motor control algorithms stored in TMS320F2810PBKS memory.
