SF32LB52x/XFlagship Model Series List

  • SF32LB52x/X:

    • xas numbers,为Lithium-ion Battery Powered系列,如SF32LB520/3/5/7,彼此可以Pin-to-pin Compatible

    • X为部分字母,为常规3.3V供电系列,包括SF32LB52B/E,彼此可以Pin-to-pin Compatible

    • X为部分字母,为特殊1.8V供电系列,包括SF32LB52A/D,用于Ultra-low Power Consumption Scenario

    • xas numbers与X为字母两个系列,相互独立,不能Pin-to-pin Compatible,3.3V型号与1.8V型号虽然可以pin-to-pin对齐,但是电压不兼容,因此也不兼容;从合封内容看的对应关系为:

      • 锂电  3.3V  1.8V

      • 520 – 52B – 52A

      • 523 – 52E – 52D

      • 525 – 52G – 52F

      • 527 – 52J  – 52H

  • SF32LB52x系列支持以下Display Interface

    • SPI/DSPI/QSPI,包括E-paper SPI Interface

    • 8080-8bit
