Overview
TMS320F2802PZQ from Texas Instruments is a 60-MHz C28x digital signal processor optimized for real-time motor control and digital power conversion, featuring 32K × 16 flash memory, 6K × 16 SARAM, 12-bit 16-channel ADC with 267-ns conversion time, and automotive-grade AEC-Q100 qualification (–40°C to 125°C) in 100-pin LQFP package.
For engineers reviewing the TMS320F2802PZQ datasheet, TMS320F2802PZQ pinout, TMS320F2802PZQ application, or TMS320F2802PZQ equivalent, key selection criteria include ePWM/HRPWM channel count, CAN interface presence, ADC resolution and timing, security key support, and Q-temperature grade compliance for automotive powertrain and battery management systems.
Technical Context
The TMS320F2802PZQ implements the fixed-point TMS320C28x CPU core with Harvard architecture, atomic operations, and unified memory model, enabling deterministic real-time execution for closed-loop control algorithms. It integrates a Peripheral Interrupt Expansion (PIE) block supporting all 43 peripheral interrupts and three 32-bit CPU timers for precise task scheduling.
Its enhanced control peripherals include three ePWM modules (6 total outputs), three HRPWM channels with 150-ps MEP resolution, two eCAP inputs, one eQEP interface, and dual SPI, single SCI, single eCAN, and I²C serial interfaces - all synchronized to a low-jitter on-chip oscillator and PLL-based clock system.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28027PZT | 60-MHz C28x core, same 32K flash/6K RAM, but lacks eCAN and includes USB PHY | Preferred for USB-enabled industrial HMI or firmware update interfaces; not suitable for CAN-based vehicle networks | Select when CAN is unnecessary and USB device capability is required for field serviceability |
| TMS320F280049CPZQ | 100-MHz C28x core, 256K flash, 100-MSPS 16-bit ADC, dual eCAN, CLA co-processor | Targeted at higher-performance applications like multi-axis servo drives or advanced inverters requiring faster computation and richer peripherals | Choose for new designs needing scalability beyond F2802PZQ's resource ceiling, especially where CLA offloads PWM/ADC tasks |
