2 Block Diagram

Figure 1 is a block diagram showing the architecture of

AMS00x Bluetooth Low Energy modules. The major

components are a Bluetooth Low Energy SoC from

Broadcom, 24MHz crystal, 8 Mbit serial flash and a PCB-

style antenna. The AMS001 version also includes a high-

efficiency DC-DC switching regulator to significantly re-

duce active mode power consumption.

The Bluetooth SoC is powered by an ARM Cortex M3-

based processor running at 24 MHz. The SoC is driven

by a 24 MHz crystal, an on-board real-time clock may

be (optionally) enabled by connecting an external

32kHz crystal.

The 8 Mbit serial flash memory stores the ACKme

TruConnect™ application and user configuration, and

enables secure Over-the-Air (OTA) wireless firmware

updates. The on-board PCB antenna simplifies RF inte-

gration into end products.

An extensive array of analog and digital peripherals in-

cluding ADCs, GPIOs, PWMs and multiple serial inter-

faces such as UART, SPI and I2C are accessible via mod-

ule pins.

The module is powered by a single-rail battery or mains

supply.
