5 WINC System Architecture

Figure 5-1 shows the WINC system architecture. The Soc contains two 32-bit CPUs APS3S-Cortus for Wi-: an

Fi and an APS3-Cortus for BLE. In addition it has separate built-in Wi-Fi IEEE-802.11 and BLE 4.0 physical

layers sharing a single nal RF front end. The firmware for Wi-Fi comprises the Wi-Fi IEEE-802.11 MAC layer

and embedded protocol stacks which ooad the host MCU. The firmware for BLE implements the entrie BLE

stack and privides an application supporting a prole defined for device provisioning. The components of the

system are described in the following sub-sections.

5.10 Bluetooth V2.1 MAC Firmware

The BLE subsystem implements all the critical real-time functions required for full compliance with Specication

of the Bluetooth System, v4.1, Bluetooth SIG. The rmware implements an integrated Bluetooth Low Energy

stack which is Bluetooth V4.1 compliant. The rmware supports access to the GAP, SMP, ATT, GATT client /

server and L2CAP service layer protocols. In the WINC3400 these services are used by a built-in AT

application for WI-Fi provisioning.

5.11 Memory Managers

The memory managers on both the Wi-Fi and BLE sides are responsible for the allocation and de-allocation of

memory chunks in both shared packet memory and data memory.

5.12 Power Managements

The Power Management modules on both the Wi-Fi and BLE sides are responsible for handling dierent power

saving modes supported by the WINC and coordinating these modes with the Wi-Fi and BLE transceiver. AT

5.13 WINC RTOS AT

The rmware includes a low-footprint real-time scheduler which allows concurrent multi-tasking on WINC AT

Wi-Fi CPU. The WINC RTOS provides semaphores and timer functionality. AT
