Texas Instruments TMS320F2806PZA

Overview

TMS320F2806PZA from Texas Instruments is a 100-MHz C28x digital signal processor optimized for real-time motor control and digital power conversion. It integrates a 32-bit CPU, 32K × 16 flash memory, 10K × 16 SARAM, 12-bit 16-channel ADC (160 ns conversion), six ePWM modules with HRPWM capability, dual CAN interfaces, and 35 GPIOs - all in a 100-pin LQFP package rated for –40°C to 85°C operation.

For engineers reviewing the TMS320F2806PZA datasheet, TMS320F2806PZA pinout, TMS320F2806PZA application, or TMS320F2806PZA equivalent, key selection criteria include deterministic 10-ns instruction cycle timing, on-chip code security (128-bit key), peripheral interrupt expansion (PIE) supporting 43 interrupts, and compatibility with TI's C2000™ real-time control ecosystem including Code Composer Studio™ and motor control libraries.

Technical Context

The TMS320F2806PZA implements the TMS320C28x CPU core with Harvard architecture, atomic operations, and unified memory model - enabling deterministic execution critical for closed-loop control. Its clock system includes an on-chip oscillator and PLL supporting 100 MHz operation at 1.8-V core/3.3-V I/O.

Peripheral integration centers on real-time control: six ePWM modules deliver up to 16 PWM outputs with 6 HRPWM channels (150-ps MEP resolution), two eCAN modules support robust industrial communication, and the 12-bit ADC features dual sample-and-hold and simultaneous sampling across two 8-channel MUX banks.

FAQ

What is the maximum operating frequency and core voltage of the TMS320F2806PZA?

The TMS320F2806PZA operates at a maximum CPU frequency of 100 MHz with a 10-ns instruction cycle time, supported by a 1.8-V core supply and 3.3-V I/O voltage. This dual-rail design optimizes power efficiency while maintaining compatibility with standard 3.3-V peripheral interfaces. The device achieves this performance using high-performance static CMOS technology and an integrated PLL.

Does the TMS320F2806PZA include hardware-based code protection?

Yes, the TMS320F2806PZA includes a 128-bit security key/lock module that protects on-chip flash memory, SARAM, and OTP blocks from unauthorized access or firmware reverse-engineering. This feature is enabled during programming and prevents read-back of secured memory contents, making it suitable for proprietary motor control or digital power algorithms.

How many PWM outputs does the TMS320F2806PZA support, and what is the resolution of its high-resolution PWM?

The TMS320F2806PZA supports up to 16 PWM outputs across six ePWM modules, including six HRPWM channels with 150-ps minimum pulse-width resolution. This level of timing precision enables accurate dead-time insertion and gate-drive control for wide-bandgap power devices such as SiC MOSFETs and GaN HEMTs in high-frequency power converters.

What ADC capabilities does the TMS320F2806PZA provide for real-time control applications?

The TMS320F2806PZA integrates a 12-bit, 16-channel ADC with two independent 8-channel input multiplexers, dual sample-and-hold circuits, and simultaneous sampling capability. Its 160-ns conversion time (6.25 MSPS) supports high-fidelity current and voltage sensing in fast-switching motor drives and digital power topologies.

Is the TMS320F2806PZA pin-compatible with other devices in the F280x family?

Yes, the TMS320F2806PZA shares identical 100-pin LQFP (PZ) packaging and pinout with TMS320F2809PZA, TMS320F2808PZA, TMS320F2802PZA, and TMS320F2801PZA. This allows direct PCB footprint reuse across the family, enabling scalable design migration - for example, upgrading from TMS320F2802PZA to TMS320F2806PZA for added flash and HRPWM without layout changes.
