RapidConnect Bridge

Rev 0.1 | October 2018

General/Overview

• Zigbee and BLE to Wi-Fi bridge

• Thread Border Router

• External pluggable power supply connected via micro-USB

• 2 Status LEDs (White and Red) - conﬁgurable through software

• Dimensions: 65x59x20.5 (LxWxH)

• Power consumption: 400mA at 5V (worst case)

Detailed Specications

• Wi-Fi (Dual band 1x1 802.11 a/b/g/n)

• Bluetooth 5.0 (Mesh and BLE)

• 802.15.4 radio (Zigbee and Thread capable)

• QCA4020 architecture which has 3 independent processors:

1. ARM Cortex-M4F @ 128 MHz is the application/host processor. It runs the

Qualcomm® networking stack as well as application code.

2. ARM Cortex-M0 @ 64 MHz, which is utilized as the connectivity control

processor for BLE and 802.15.4.

3. XTENSA7 @ 130MHz which is a dedicated processor to run the Wi-Fi dual

band function.

Benets:

• Qualcomm Wi-Fi, BLE and 15.4 code has a known execution environment

without generating competition for processor resources from customer

code.

• The customer maintains ﬂexibility to choose the operating system for their

code.

• The execution environment of Qualcomm code is easier to separate from

customer code from a security perspective.

• Built in security hardware and trusted code support.

Memory

The RapidConnect Bridge is a RAM based device, with dedicated space for Customer

Applications. The device also supports Execute in Place ( XiP ) directly from its

external ﬂash with a speed penalty.

It is equipped with an external 32Mb SPI Flash that is used to:

• Store three versions of the ﬁrmware image simultaneously:

– Existing image

– Upgrade image

– Factory reset image

• Store RAW data in a Flash File System

• Extend code space through Execute in Place (XIP).

In typical MCU terms customers will have the following available for their

application, with vendor supplied libraries stored in a separate region :

• Flash - 296KB (expandable through XIP)

• RAM - 174 KB

• ‘External Storage’ - ~1MB
