品佳集团力推 Microchip-Atmel ATSAMG55 Cortex M4 MCU助力VR sensor Hub 应用

 2016-11-09

Microchip-Atmel  SMART SAM G 系列针对超低功耗和高性能应用进行了优化。其小巧的外形基于 ARM® Cortex®-M4 内核,这些器件与浮点计算单元 (FPU) 捆绑,封装尺寸极小,仅为 3 x 3 mm 49 球型 WLCSP,工作效率无与伦比。SAM G 系列包含一组经过优化且高效的串行外设,包括一个 12 位 ADC、DMA 并具有最佳 SRAM 与闪存比。SAM G 器件是传感器集线器和电池供电消费应用的理想之选。

SAM G 包括四个系列:SAM G51、SAM G53、SAM G54 和 SAM G55。这些器件完全兼容,甚至连 WLCSP 封装也一样。
