Product details
Overview
TMS320F28065UPZPS from Texas Instruments is a 90-MHz C28x-based real-time microcontroller with integrated FPU, CLA, and 12-bit 3.46-MSPS ADC, designed for closed-loop motor control and digital power conversion in industrial inverters and EV charging modules.
For engineers reviewing the TMS320F28065UPZPS datasheet, TMS320F28065UPZPS pinout, TMS320F28065UPZPS application, or TMS320F28065UPZPS equivalent, this page delivers verified package mapping (100-pin HTQFP), confirmed peripheral count (8 ePWM, 3 eCAP, 4 HRCAP, 2 eQEP), flash/RAM configuration (64KB Flash / 34KB RAM), and thermal rating (–40°C to 125°C).
Technical Context
The TMS320F28065UPZPS implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory model, paired with a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its VCU extends instruction set support for complex math, CRC, and Viterbi operations.
It integrates dual-sample-and-hold 12-bit ADC with 16-channel input multiplexing and ratio-metric reference capability, alongside three analog comparators with internal 10-bit DACs routed directly to ePWM trip zones - enabling fast overcurrent protection without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28069PZPS | 128KB Flash, 50KB RAM, VCU enabled, CLA disabled - higher memory, no independent control accelerator | Better suited for complex motion profiles with large lookup tables; lacks CLA for ultra-low-latency current loops | Select when firmware size exceeds 64KB or VCU-based CRC/complex math is required, but CLA is unnecessary |
| TMS320F280049CPZPR | Newer C28x+CLA architecture, 256KB Flash, 100KB RAM, enhanced analog (16-bit ADC, 4x PGA), 100-pin HTQFP | Supports higher-precision current sensing and advanced observer-based control; roadmap-compliant replacement | Choose for new designs requiring extended analog front-end, larger memory, or long-term supply assurance beyond F2806x lifecycle |
Compared with TMS320F28065UPZPS, the TMS320F28069PZPS offers more Flash/RAM but omits CLA - trading real-time determinism for storage capacity; the TMS320F280049CPZPR provides generational improvements in analog precision, memory, and toolchain support while maintaining pin compatibility for migration paths.

FAQ
What is the maximum operating temperature rating for the TMS320F28065UPZPS?
The TMS320F28065UPZPS is rated for operation from –40°C to +125°C (S-grade), validated per JEDEC JESD22-A108. This rating applies to the full 100-pin HTQFP (PZP) package with PowerPAD™ thermal pad properly soldered to the PCB ground plane. The device meets automotive-grade thermal robustness requirements without derating up to 125°C ambient.
Does the TMS320F28065UPZPS include a USB interface, and what modes does it support?
Yes, the TMS320F28065UPZPS integrates a full-speed USB 2.0 controller supporting both device mode (12 Mbps) and host mode (12 Mbps or 1.5 Mbps). It uses dedicated USB0DP and USB0DM pins (Pins 26 and 27) and requires external 27-Ω series resistors and ESD protection diodes. USB functionality is confirmed in the F2806xU variant family, and TMS320F28065UPZPS is explicitly listed as a U-series part in TI's device comparison table.
How much Flash memory is available on the TMS320F28065UPZPS, and is it secured?
The TMS320F28065UPZPS contains 64KB of on-chip Flash memory organized as 16-bit words, partitioned into eight equal sectors. All Flash is protected by TI's Code Security Module (CSM) using a 128-bit password key stored in OTP, preventing unauthorized read-out or firmware reverse-engineering. Secure boot ROM (32KB) further enforces authenticated startup sequences.
What distinguishes the CLA in the TMS320F28065UPZPS from the main C28x CPU?
The CLA in the TMS320F28065UPZPS is a fully autonomous 32-bit floating-point math accelerator with its own program and data RAM, interrupt vector table, and register set. It executes control law code in parallel with the main C28x CPU - eliminating CPU load during high-frequency current/voltage loops. Unlike the CPU, the CLA has no cache or branch prediction, ensuring deterministic, cycle-exact execution critical for sub-microsecond control timing.
Which analog peripherals are integrated into the TMS320F28065UPZPS for motor control feedback?
The TMS320F28065UPZPS integrates a 12-bit dual-sample-and-hold ADC with 16 input channels and 3.46 MSPS throughput, three analog comparators with internal 10-bit DACs, an on-chip temperature sensor, and dedicated analog I/O pins (AIO0–AIO14). These enable simultaneous current/voltage sensing, hardware-triggered fault shutdown via comparator-to-ePWM routing, and thermal monitoring - all without CPU intervention.
