MPN： TMS320F28069PZT ✓ 啟用中TMS320F28069PZT 概覽
A microcontroller (MCU) is a compact integrated circuit designed to govern a specific operation in an embedded system. It contains a processor core, memory, and programmable input/output peripherals. The TMS320F28069PZT belongs to the C2000 family of real-time control MCUs, which are optimized for industrial and automotive applications requiring high-performance signal processing and control. The C28x core is a 32-bit fixed-point and floating-point architecture, and the CLA is a co-processor that enables parallel execution of control algorithms, offloading the main CPU.
Key features include a 90 MHz C28x CPU with FPU, a 32-bit CLA, a VCU for Viterbi and complex math, 256 KB flash, 100 KB RAM, a 12-bit ADC with up to 16 channels, and multiple communication interfaces including USB 2.0, CAN, SPI, I2C, and UART. The device also features a 6-channel DMA controller, an internal voltage regulator for single-rail operation, and low-power modes. The high integration and peripheral set make it suitable for complex real-time control applications.
Technically, the TMS320F28069PZT uses a Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. The FPU accelerates floating-point math, while the CLA can execute control loops independently, reducing CPU load. The VCU accelerates Viterbi decoding and complex arithmetic, beneficial for communication and motor control. The device includes a programmable control law accelerator, which is a 32-bit floating-point unit that can run at the same clock speed as the CPU, providing additional processing power for time-critical tasks.
Typical applications include motor control (e.g., field-oriented control of AC induction and BLDC motors), digital power conversion (e.g., solar inverters, server power supplies), industrial automation, and renewable energy systems. The device's high-speed ADC and PWM modules enable precise control loops, while the CAN and USB interfaces facilitate communication in industrial networks.
When designing with this MCU, ensure proper decoupling of the VDD and VDDIO pins with 100 nF capacitors placed close to the pins. The internal voltage regulator allows single-rail operation, but an external 1.8V supply can be used for lower power dissipation. The device requires a 10 MHz crystal or an external clock source; the on-chip oscillator can also be used with a 10 MHz crystal.

主要差異化特點
- Integrated VCU for Viterbi and complex math (對比TMS320F28069MPZT)
- Higher performance than TMS320F2806PZA (對比TMS320F2806PZA)
- Pin-compatible with higher-performance TMS320F28377SPTPQ (對比TMS320F28377SPTPQ)
設計說明
The TMS320F28069PZT has an internal voltage regulator that allows single-rail operation from a 3.3V supply. However, for lower power dissipation, an external 1.8V supply can be connected to the VDD pins. Ensure proper decoupling with 100 nF capacitors placed close to each VDD and VDDIO pin, and a 10 uF bulk capacitor on the main supply rail.
For the 100-pin LQFP package, use a 4-layer PCB with dedicated power and ground planes. Place the crystal oscillator (10 MHz) and its load capacitors as close to the X1/X2 pins as possible, with a ground guard ring to minimize noise. Route high-speed signals like USB and CAN with controlled impedance and proper termination.
Do not exceed the absolute maximum ratings for VDDIO (3.6V) and VDD (2.1V). Ensure the boot mode pins are configured correctly to avoid unintended boot from flash. When using the internal oscillator, note that it requires a 10 MHz crystal; using a different frequency may require software configuration. Also, avoid floating unused GPIO pins by configuring them as outputs or enabling internal pull-ups.
