Texas Instruments TMS320F28034PAGQ

Overview

TMS320F28034PAGQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated CLA accelerator, 32KB flash, 10KB SARAM, and automotive-qualified AEC-Q100 Grade 1 (–40°C to 125°C) operation. It delivers high-resolution PWM control, dual-sample-and-hold 12-bit ADC (4.6 MSPS), and eCAN/I2C/SPI/SCI/LIN peripherals for closed-loop motor and power conversion systems.

For engineers reviewing the TMS320F28034PAGQ datasheet, TMS320F28034PAGQ pinout, TMS320F28034PAGQ application, or TMS320F28034PAGQ equivalent, key selection criteria include CLA support for independent floating-point control law execution, 12-channel ePWM with HRPWM capability, on-chip temperature sensor, code security module with 128-bit key, and TQFP-64 package compatibility with industrial and automotive power electronics designs.

Technical Context

The TMS320F28034PAGQ implements a Harvard-architecture C28x CPU with atomic instructions and unified memory mapping, enabling deterministic real-time interrupt response within 6 cycles. Its CLA executes 32-bit floating-point math independently of the main CPU, offloading time-critical control loops such as field-oriented motor control or digital PFC algorithms.

Peripheral integration includes a 12-bit ADC with 16 input channels, dual sample-and-hold, and 216.67 ns conversion time; three 32-bit CPU timers; and enhanced control modules-ePWM (12 channels), eCAP (1 input), eQEP (1 module), HRCAP (2 modules), and comparators with integrated DACs-configured via multiplexed GPIO pins in the 64-pin TQFP package.

FAQ

What is the maximum operating frequency of the TMS320F28034PAGQ?

The TMS320F28034PAGQ operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67 ns instruction cycle time. This speed is achieved using an internal PLL driven by either an external crystal (X1/X2) or external clock source, with the on-chip oscillator supporting frequencies from 4 MHz to 20 MHz. The TMS320F28034PAGQ maintains this performance across its full AEC-Q100 Grade 1 temperature range (–40°C to +125°C).

Does the TMS320F28034PAGQ include a hardware accelerator for control algorithms?

Yes, the TMS320F28034PAGQ integrates a programmable Control Law Accelerator (CLA), a 32-bit floating-point math engine that executes control code independently of the main C28x CPU. This allows concurrent execution of time-critical tasks such as field-oriented control or digital PFC, reducing CPU load and improving real-time determinism. The CLA is present in the TMS320F28034PAGQ and confirmed in the device comparison table.

What analog-to-digital converter capabilities does the TMS320F28034PAGQ provide?

The TMS320F28034PAGQ features a 12-bit ADC with 16 input channels, 4.6 MSPS sampling rate, and 216.67 ns conversion time. It includes dual sample-and-hold circuitry for simultaneous sampling, ratio-metric reference support (VREFHI/VREFLO), and direct routing to ePWM trip zones. These capabilities are specified in the device comparison table and functional description for the TMS320F28034PAGQ.

Is the TMS320F28034PAGQ pin-compatible with other devices in the F2803x family?

Yes, the TMS320F28034PAGQ shares the same 64-pin TQFP (PAG) package footprint and pinout with other PAG-option F2803x devices-including TMS320F28030PAG, TMS320F28031PAG, TMS320F28032PAG, TMS320F28033PAG, and TMS320F28035PAG-as confirmed in the mechanical packaging data and pin diagrams. Peripheral signal assignments and GPIO multiplexing are consistent across the PAG variants.

What security features protect firmware on the TMS320F28034PAGQ?

The TMS320F28034PAGQ includes a dedicated code-security module with 128-bit encryption key and lock mechanism, protecting on-chip flash, SARAM, and OTP memory blocks from unauthorized read or copy. This prevents firmware reverse engineering and ensures intellectual property protection in production units. Security configuration is persistent and enforced at boot, as documented in the TMS320F28034PAGQ technical reference manual.
