Overview

TMS320F2802PZA 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, 6K × 16 SARAM, 12-bit 16-channel ADC with 267 ns conversion time, three 32-bit CPU timers, and ePWM/ECAP/eQEP peripherals - deployed in brushless DC motor drives and AC-DC power supplies.

For engineers reviewing the TMS320F2802PZA datasheet, TMS320F2802PZA pinout, TMS320F2802PZA application, or TMS320F2802PZA equivalent, key selection criteria include its 100-pin LQFP (PZ) package, 1.8-V core / 3.3-V I/O voltage architecture, integrated code security module, and support for SCI-A, SPI-A/B, I2C-A, and single eCAN-A interfaces in industrial embedded control designs.

Technical Context

The TMS320F2802PZA implements the fixed-point TMS320C28x CPU core with Harvard bus architecture, atomic operations, and unified memory model, enabling deterministic real-time execution. It integrates a Peripheral Interrupt Expansion (PIE) block supporting 43 peripheral interrupts and uses little-endian data organization.

Its system control includes an on-chip oscillator, PLL-based clock generation, watchdog timer, and low-power modes (IDLE, STANDBY, HALT). The device supports boot from SCI, SPI, CAN, I2C, or parallel I/O via 4K × 16 boot ROM containing standard math tables.

FAQ

What is the maximum operating frequency of the TMS320F2802PZA?

The TMS320F2802PZA operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This speed is achieved using an internal PLL that multiplies the input clock (e.g., from X1/X2 crystal or external source). The device does not support 100-MHz operation - that capability is reserved for higher-tier F2806/F2808/F2809 variants. All timing specifications in the datasheet assume this 60-MHz base clock.

Does the TMS320F2802PZA include on-chip flash memory and security features?

Yes, the TMS320F2802PZA integrates 32K × 16 words (512 KB) of on-chip flash memory and supports full 128-bit code-security locking of flash, SARAM, and OTP blocks. This prevents unauthorized readout or firmware cloning. The security module enforces secure boot and restricts JTAG access when enabled. Unlike some later C2000 devices, it does not include a separate 1K × 16 OTP ROM - its security key resides in flash-protected memory space.

How many PWM outputs does the TMS320F2802PZA support, and what advanced timing features are included?

The TMS320F2802PZA supports six ePWM outputs (ePWM1–ePWM3, each with A/B pairs) and includes trip-zone inputs (TZ1–TZ6) for hardware fault shutdown, dead-band generation, and synchronization signals (EPWMSYNCI/EPWMSYNCO). It also provides three HRPWM outputs with 150-ps minimum edge placement resolution - essential for high-frequency digital power control. These features are implemented in dedicated hardware, ensuring deterministic timing independent of CPU load.

What analog-to-digital converter (ADC) capabilities does the TMS320F2802PZA provide?

The TMS320F2802PZA integrates a 12-bit successive-approximation ADC with 16 input channels, organized into two 8-channel multiplexers (ADCINA and ADCINB). It achieves a 267 ns conversion time (3.75 MSPS), supports simultaneous sampling across both banks, and includes two sample-and-hold circuits. Internal references (ADCREFP/M) and external reference support (ADCRESEXT) enable flexible sensor interfacing without external op-amps in most industrial applications.

Which communication interfaces are available on the TMS320F2802PZA, and are they pin-compatible with other F280x devices?

The TMS320F2802PZA includes SCI-A (UART), SPI-A/B, I2C-A, and one eCAN-A controller - consistent with the F2801/F2802/F2806 pinout group. All these interfaces use dedicated pins mapped in the 100-pin PZ package and are electrically and functionally identical across this subset. However, it lacks the second CAN (eCAN-B), second SCI, and additional SPI modules found in F2808/F2809, so migration to those devices requires firmware and layout adjustments.
