TMS320F28055PNS
Piccolo微处理器 Piccolo Microcontrollers
Description
The F2805x Piccolo™ family of microcontrollers provides the power of the C28x™ core and Control Law
Accelerator CLA coupled with highly integrated control peripherals in low pin-count devices. This family
is code-compatible with previous C28x-based code, as well as providing a high level of analog integration.
