F28027PTT 概要
A microcontroller (MCU) is a compact integrated circuit that combines a processor core, memory, and programmable input/output peripherals on a single chip. The C28x core is a 32-bit fixed-point DSP-optimized architecture from Texas Instruments, specifically engineered for real-time control tasks. It sits within the C2000 family, which is a subset of microcontrollers tailored for industrial and automotive control systems, such as motor drives, power conversion, and digital power supplies. The C28x core excels at executing control algorithms with high precision and low latency, making it a preferred choice for closed-loop systems.
Key features of the F28027PTT include a 60 MHz clock speed, 64KB flash memory, and a rich set of control peripherals. It integrates a 12-bit ADC, multiple PWM channels, and communication interfaces like SPI, SCI (UART), and I2C. The device operates over a temperature range of -40°C to 105°C, making it suitable for harsh environments. The internal voltage regulator simplifies power supply design, allowing operation from a single 3.3V rail.
Technically, the F28027PTT leverages the C28x core's Harvard architecture, which enables simultaneous instruction and data access, improving throughput. The flash memory supports on-chip programming, facilitating firmware updates in the field. The device also includes a boot ROM with factory-programmed bootloader routines, enabling flexible boot options from various interfaces. The analog-to-digital converter (ADC) offers 12-bit resolution with multiple sample-and-hold channels, crucial for precise sensor measurements in control loops.
Typical applications include white goods (such as washing machines and refrigerators), switched-mode power supplies (SMPS), and DC-DC multiple-output power supplies. The F28027PTT's high-performance C28x core and integrated peripherals make it ideal for implementing complex control algorithms like field-oriented control (FOC) for motors and digital power conversion. Its low pin count and small package footprint also suit space-constrained designs.
When designing with this device, ensure proper decoupling of the power supply pins and consider the thermal characteristics of the LQFP package. The internal voltage regulator requires an external capacitor for stability. Additionally, the ADC reference pins should be filtered to minimize noise, as this directly impacts measurement accuracy in control applications.

設計ノート
The F28027PTT has an internal voltage regulator that requires an external capacitor (typically 1uF to 10uF) on the VREG output pin for stability. Ensure the 3.3V supply is clean and well-decoupled with 0.1uF ceramic capacitors near each VDD pin. The internal regulator allows single-rail operation, simplifying power supply design, but proper decoupling is critical to prevent noise-induced resets.
For the 48-pin LQFP package, ensure adequate copper pour for thermal dissipation. The exposed pad (if present) should be soldered to a thermal via array to improve heat transfer. Place decoupling capacitors as close as possible to the power pins. For ADC accuracy, route analog inputs away from digital traces and provide a clean analog ground plane.
Do not exceed the absolute maximum ratings for supply voltage (3.3V typical). Ensure the crystal oscillator load capacitors match the crystal specification. When using the ADC, avoid floating input pins as they can cause excessive current draw. Also, be aware that the flash memory has a limited number of write cycles; use wear-leveling if frequent updates are expected.
