Product details
Overview
TMS320F28069PZPQ from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and VCU, designed for closed-loop motor control and digital power conversion. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel 12-bit ADC at 3.46 MSPS, and 8 HRPWM-capable ePWM channels - deployed in EV charging station power modules and solar string inverters.
For engineers reviewing the TMS320F28069PZPQ datasheet, TMS320F28069PZPQ pinout, TMS320F28069PZPQ application, or TMS320F28069PZPQ equivalent, key selection criteria include AEC Q100 qualification (–40°C to 125°C), HTQFP-100 PowerPAD™ package thermal performance, dual-edge HRPWM timing resolution, and CLA-accelerated floating-point control law execution independent of the main CPU.
Technical Context
The TMS320F28069PZPQ implements a Harvard bus architecture with atomic C28x instructions and unified memory programming, enabling deterministic real-time response. Its CLA executes 32-bit floating-point math independently, while the VCU extends the instruction set for complex multiply, Viterbi, and CRC operations - critical for field-oriented control (FOC) and sensorless motor algorithms.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO referencing, analog comparators routed directly to ePWM trip zones, and dual 10-bit DACs for feedback signal conditioning. The device uses an internal voltage regulator for single 3.3-V rail operation and supports dual zero-pin oscillators plus external crystal input for robust clocking in automotive-grade systems.

FAQ
What is the operating temperature range certified for the TMS320F28069PZPQ?
The TMS320F28069PZPQ is AEC Q100-qualified for operation from –40°C to 125°C ambient temperature, validated per stress test standards including thermal cycling, high-temperature operating life, and latch-up immunity - making it suitable for under-hood automotive power electronics and industrial environments with elevated thermal loads.
Does the TMS320F28069PZPQ include hardware security features?
Yes, the TMS320F28069PZPQ integrates a Code Security Module (CSM) with 128-bit password protection, encrypted flash/SARAM access, and one-time programmable (OTP) ROM for secure key storage. These features prevent unauthorized firmware readout and enable secure boot authentication in safety-critical automotive and industrial applications.
How many high-resolution PWM channels does the TMS320F28069PZPQ support?
The TMS320F28069PZPQ supports 8 high-resolution PWM (HRPWM) channels distributed across its 8 ePWM modules. Each HRPWM channel enables sub-nanosecond duty-cycle adjustment via dual-edge control, critical for precise gate driving in SiC and GaN-based power converters operating above 100 kHz.
Is the TMS320F28069PZPQ pin-compatible with other F2806x devices?
No, the TMS320F28069PZPQ is not pin-compatible with lower-pin-count variants like the 80-pin PFP/PN packages. However, within the 100-pin PZ/PZP family (e.g., TMS320F28069PZ, TMS320F28069PZPQ), pin assignments and electrical characteristics are identical - allowing direct substitution where AEC Q100 qualification is required.
