TMS320F28026PTT

Piccolo微处理器 Piccolo Microcontrollers

Description

The F2802x Piccolo™ family of microcontrollers provides the power of the C28x core coupled with highly

integrated control peripherals in low pin-count devices. This family is code-compatible with previous C28x based code, and also provides a high level of analog integration.
