Product details
Overview
TMS320F28035PAGS from Texas Instruments is a 64-pin TQFP C2000™ real-time microcontroller featuring a 60MHz C28x CPU, integrated Control Law Accelerator (CLA), 64KB on-chip Flash, 10KB SARAM, 12-bit 4.6 MSPS ADC with 16 channels, and dual-edge high-resolution PWM for motor control and digital power applications.
For engineers reviewing the TMS320F28035PAGS datasheet, TMS320F28035PAGS pinout, TMS320F28035PAGS application, or TMS320F28035PAGS equivalent, key selection criteria include CLA co-processing capability, HRPWM timing resolution, eCAN/LIN interface support, analog integration (comparators + temperature sensor), and automotive-grade –40°C to 125°C operation (S grade).
Technical Context
The TMS320F28035PAGS implements a Harvard-architecture 32-bit C28x CPU with atomic instructions and zero-wait-state memory access, paired with an independent 32-bit floating-point CLA for parallel control-loop execution. Its peripheral set includes seven ePWM modules (four with HRPWM), three eCAP inputs, one eQEP module, and dual-sample-and-hold ADC with ratio-metric reference support.
System-level features include single 3.3V supply operation with internal voltage regulation, JTAG boundary scan (IEEE 1149.1), programmable GPIO filtering, and hardware-based code security via 128-bit key locking of Flash/SARAM/OTP memory blocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28035PAGT | Same silicon, commercial temperature range (–40°C to 105°C); no automotive qualification | Not suitable for under-hood automotive use; lower cost for industrial motor drives | Select PAGT when ambient operating temperature remains ≤105°C and AEC-Q100 compliance is not required. |
| TMS320F28034PAGS | Identical package and temperature grade, but with 32KB Flash, 8KB SARAM, and no CLA accelerator | Lacks CLA for complex control algorithms; reduced memory limits firmware scalability | Choose PAGS only if CLA is unnecessary and memory requirements fit within 32KB Flash/8KB RAM. |
Compared with TMS320F28035PAGS, the PAGT variant trades automotive qualification for lower cost in non-automotive environments, while the PAGS-based F28034 offers identical packaging and temperature rating but omits the CLA and halves Flash/RAM-making it suitable only for less demanding control tasks.
