요즘 IoT도 그렇고, 저전력이 많이 잇슈화 되는것 같습니다.
기존 Lxx 씨리즈 다음으로 더 적게 먹는 L0xx 씨리즈를 만들었네요.
Discovery 보드에는 E-ink, E-Paper 등등등 불리우는 E-display 가 달려 있습니다.
기존에는 디스플레이 방식의 차이로 인해 저전력, 느린 화면전환, refresh가 없어서 눈이 책을 보는것 같은 편안함을 느끼는 것을
특징으로만 알고 있었는데, 전원이 나가도 이미지가 그대로 남아 있네요.

T : TI
E : EFM ?
전력 얼마나 먹는지는 안나오고, 저전압 고클럭을 강조 하네요.
