Ameba series, IoT Low-Energy SoC

General Description

The Realtek RTL8711AM is a highly integrated single-chip with a low-power-consumption mechanism ideal for IoT (Internet of Things) applications. It combines an ARM®Cortex™-M3 MCU, WLAN MAC, a 1T1R capable WLAN baseband/RF and NFC in a single chip. It also provides configurable GPIOs that can function as digital peripherals for various product applications and control usage.
The RTL8711AF integrates internal memories and flash to minimize IoT end-product size and reduce development cost. The embedded memory configuration enables simpler and faster application development.
