Product details
Overview
TMS320F28069FPZPQ from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and VCU, designed for high-precision 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 16 ePWM channels (8 HRPWM-capable), operating across –40°C to 125°C for automotive AEC Q100-compliant systems.
For engineers reviewing the TMS320F28069FPZPQ datasheet, TMS320F28069FPZPQ pinout, TMS320F28069FPZPQ application, or TMS320F28069FPZPQ equivalent, key selection criteria include its dual-edge HRPWM capability, on-chip temperature sensor, 128-bit code security, USB 2.0 device/host support, and AEC Q100 qualification for EV charging and inverter control.
Technical Context
The TMS320F28069FPZPQ implements a Harvard bus architecture with atomic operations and unified memory programming, enabling deterministic real-time execution. Its C28x CPU executes single-cycle 32×32 MAC and dual 16×16 MAC operations, while the independent CLA accelerates floating-point control law computation without CPU intervention.
Peripheral integration includes three eQEP modules, four HRCAP units, six-channel DMA, and analog subsystems featuring three comparators with internal 10-bit DACs routed directly to ePWM trip zones. The device supports ratio-metric ADC references (VREFHI/VREFLO) and dual sample-and-hold for simultaneous sampling of up to 16 analog inputs.

FAQ
What is the operating temperature range and automotive qualification status of the TMS320F28069FPZPQ?
The TMS320F28069FPZPQ is rated for –40°C to +125°C and carries AEC Q100 qualification (Grade 0), confirming its suitability for under-hood automotive applications including EV charging stations and onboard power converters. This qualification covers stress testing for temperature cycling, humidity, and mechanical shock per automotive reliability standards.
Does the TMS320F28069FPZPQ support USB functionality, and what modes are available?
Yes, the TMS320F28069FPZPQ integrates a full-speed USB 2.0 PHY supporting both device mode (e.g., firmware update via PC) and host mode (e.g., connecting USB-to-UART bridges or HID peripherals). It requires no external transceiver and uses dedicated USB0DP/USB0DM pins routed to the 100-pin PZP package.
How many high-resolution PWM channels does the TMS320F28069FPZPQ provide, and what is their key timing capability?
The TMS320F28069FPZPQ provides eight high-resolution PWM (HRPWM) channels - one per ePWM module - enabling dual-edge modulation with 150-ps resolution. This allows precise frequency and phase control for resonant topologies in wireless charging and GaN-based power supplies without external delay ICs.
What security mechanisms are implemented in the TMS320F28069FPZPQ to protect firmware?
The TMS320F28069FPZPQ includes a Code Security Module (CSM) with 128-bit password protection, allowing selective locking of flash, RAM, and OTP memory blocks. Once secured, debug access is disabled unless the correct password is entered, preventing reverse engineering and unauthorized firmware extraction.
Is the TMS320F28069FPZPQ pin-compatible with other devices in the F2806x family, and which packages share the same footprint?
The TMS320F28069FPZPQ uses the 100-pin HTQFP PowerPAD™ (PZP) package, which shares mechanical and thermal footprint compatibility with TMS320F28069PZ (LQFP-100) but differs electrically due to PowerPAD grounding requirements. It is not pin-compatible with 80-pin variants (PFP/PN) or other F2806x derivatives like F28069M/F due to peripheral signal mapping differences.
