Product details
Overview
TMS320F28034PNTR from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated Control Law Accelerator (CLA), 64KB flash, 10KB SARAM, 12-bit ADC (4.6 MSPS), 14 ePWM channels, and HRPWM capability - deployed in motor control, solar inverters, and EV charging power modules.
For engineers reviewing the TMS320F28034PNTR datasheet, TMS320F28034PNTR pinout, TMS320F28034PNTR application, or TMS320F28034PNTR equivalent, key selection criteria include CLA availability, 80-pin LQFP package compatibility, 60-MHz deterministic timing, eCAN/I2C/SCI peripheral support, and AEC-Q100 qualification status for automotive-grade designs.
Technical Context
The TMS320F28034PNTR implements a Harvard-architecture C28x CPU executing at 60 MHz (16.67 ns cycle time) with atomic operations and fast interrupt response. Its CLA executes floating-point control law code independently of the main CPU, enabling parallel real-time loop execution.
It integrates dual-sample-and-hold 12-bit ADC with 16 input channels, 14 ePWM outputs (including 7 high-resolution channels), 3 comparators with DACs, eCAN, I2C, SPI, SCI, LIN, and eQEP - all accessible via 45 GPIO pins multiplexed across 80 LQFP terminals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28035PNTR | 64KB flash, 10KB SARAM, CLA enabled - identical package and pinout; adds 2 more ePWM channels and 2 HRCAP modules | Higher PWM channel count supports 6-phase inverters or dual-motor control; enhanced capture supports resolver feedback | Select when additional PWM or HRCAP resources are required without changing PCB layout |
| TMS320F28034PAGT | 64-pin TQFP package (10 mm × 10 mm); same core, CLA, memory, and peripherals - but 33 GPIOs and reduced ePWM count (12 channels) | Compact footprint suits space-constrained designs; lower I/O count acceptable for simpler motor drives or DC/DC controllers | Select when board area is constrained and full 45-GPIO capability is not needed |
Compared with TMS320F28035PNTR, the TMS320F28034PNTR offers identical CLA acceleration and 80-pin LQFP compatibility but trades 2 ePWM/HRCAP channels for cost optimization; versus TMS320F28034PAGT, it provides 12 additional GPIOs and 2 more ePWM outputs in a larger, thermally robust package.

FAQ
What is the maximum operating frequency of the TMS320F28034PNTR CPU core?
The TMS320F28034PNTR CPU core operates at a maximum frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This timing is achieved using the internal PLL driven by either an external crystal (X1/X2) or single-ended clock input (XCLKIN), with system clock configuration managed via the CLKCTL register. All timing-critical peripherals - including ePWM, ADC, and CLA - are synchronized to this SYSCLK.
Does the TMS320F28034PNTR include a Control Law Accelerator (CLA)?
Yes, the TMS320F28034PNTR includes a dedicated 32-bit floating-point Control Law Accelerator (CLA) that executes control algorithms independently of the main C28x CPU. The CLA has direct access to key peripherals including ePWM, ADC, and RAM, enabling parallel real-time loop execution - for example, running FOC current loops on the CLA while the CPU handles communication, diagnostics, and higher-level state machines.
What package type and pin count does the TMS320F28034PNTR use?
The TMS320F28034PNTR uses an 80-pin Low-Profile Quad Flatpack (LQFP) package, designated "PN" in Texas Instruments' ordering nomenclature. Its body size is 12.0 mm × 12.0 mm with 0.5-mm pitch. This package provides 45 GPIOs, full peripheral signal access, and thermal performance suitable for industrial motor drive and power conversion applications.
How much on-chip flash and RAM does the TMS320F28034PNTR provide?
The TMS320F28034PNTR integrates 64KB of on-chip flash memory (16-bit word organization) and 10KB of SARAM (also 16-bit word). Flash supports secure code storage with 128-bit encryption and lock bits; SARAM is zero-wait-state and accessible by both CPU and CLA. Additionally, the device includes 8KB boot ROM and 1KB one-time-programmable (OTP) memory for calibration data or security keys.
Is the TMS320F28034PNTR qualified for automotive applications?
No - the TMS320F28034PNTR is the commercial/industrial variant rated for –40°C to 105°C operation. For automotive applications, Texas Instruments offers the TMS320F28034Q1PNTR, which is AEC-Q100 qualified for operation from –40°C to 125°C and includes additional reliability testing and traceability controls. Both share identical electrical specifications and pinout, but only the Q1 suffix denotes automotive qualification.
