ST MCU 적용제품

STM32F373CCT6 - Sphero BB-8

스타워즈 깨어난 포스(Star Wars : The Force Awakens)에 새롭게 등장한 BB-8입니다.



Sphero에서 제작한 BB-8은 STM32F373CCT6을 Main MCU로 사용하였습니다.

Sphero는 기존에도 이와 비슷한 장난감인 Sphero 1을 출시한 적이 있습니다.




Sphero 1은 Cortex-M3 Core의 STM32F103CBT6을 사용하였습니다.


스타워즈 출시에 맞춰 새롭게 발표한 BB-8은 Cortex-M4 Core를 사용한 STM32F373CCT6을 적용하였습니다.






STM32F373은 FPU가 내장된 Cortex-M4 Core를 사용한 제품입니다.

최대 72Mhz의 속도로 동작하며 특징으로 16Bit Sigma Delta ADC가 내장되어 있습니다.
