品佳集團力推 Microchip Atmel ATSAMG55 Cortex M4 MCU 助力 VR sensor Hub 應用


Microchip-Atmel  SMART SAM G 系列針對超低功耗和高性能應用進行了優化。其小巧的外形基於 ARM® Cortex®-M4 內核,這些器件與浮點計算單元 (FPU) 捆綁,封裝尺寸極小,僅為 3 x 3 mm 49 球型 WLCSP,工作效率無與倫比。SAM G 系列包含一組經過優化且高效的串列外設,包括一個 12 位 ADC、DMA 並具有最佳 SRAM 與快閃記憶體比。SAM G 器件是感測器集線器和電池供電消費應用的理想之選。

SAM G 包括四個系列:SAM G51、SAM G53、SAM G54 和 SAM G55。這些器件完全相容,甚至連 WLCSP 封裝也一樣。
