AMS00x • Embedded Bluetooth Low Energy Solution

General Description, Section 1

1 General Description

The family of AMS00x ‘Bobcat’ modules from ACKme Networks is based on an ultra-low power Bluetooth Low Energy (Bluetooth Smart) SoC from Broadcom Corporation. All modules incorporate serial-flash memory and a printed antenna to provide a state-of-the-art fully-certified Bluetooth 4.1 solution.

An integrated solution avoids difficult RF layout and enables designers to rapidly embed Bluetooth Low Energy into virtually any device.

The AMS001 (Low Power) version slashes active power consumption for applications requiring multi-year battery life, while the AMS002 (Low Cost) version provides the lowest cost solution suitable for price sensitive applications. The modules are 100% footprint compatible.

Modules ship with ACKme TruConnect, an easy-to-use application enabling control and configuration via UART-serial and remote terminal interfaces. TruConnect virtually eliminates difficult and time-consuming software development effort and vastly reduces product development cycles.

With dimensions of just 17.6 x 11.4 mm, a wide temperature range, and an ultra-low power version, the module is suitable for integration into any batterypowered embedded wireless application.

The Bluetooth Low Energy SoC from Broadcom is purpose-designed to support the entire spectrum of Bluetooth Smart use cases for medical, home automation, accessory, sensor, retail and wearable market segments. Superior receive sensitivity, an integrated RF transmit power amplifier and transmit/receive switch, along with the on-board antenna, provide extended range and full compatibility with all Bluetooth 4.1 devices.

At the heart of all AMS00x modules is a Bluetooth Low Energy SoC with a high-performance ARM® 32-bit Cortex™-M3 core operating at a frequency of 24 MHz. The SoC includes is configured to boot applications stored in the 512xkB serial flash memory available on-board the module.

 7 x A/D converter channels  2 x UART interfaces: 1 x 4-wire, 1 x 2-wire  1 x SPI master, 1 x SPI slave bus  1 x I  Up to 12 x ultra-low power wake input  32kHz crystal interface

The module may be powered directly from a battery supply in the range 1.8-3.6V including 2xAAA, 2xAA, or a single Lithium coin cell.

Internal power domains are automatically adjusted to minimize power dissipation based on user activity. Various power modes, including an ultra-low power deep sleep mode, are provided to minimize total average power consumption and maximize battery life.

Custom factory settings may be saved to a non-erasable area of static memory to enable out-of-the-box custom product configuration and the ability to return products incorporating the module to a known factory reset state.

The module may be woken from deep sleep mode by a level transition on the GPIO assigned for stream mode selection. Other GPIOs may be dynamically allocated for control and status including a BLE connection indicator, serial bus mode control and status indicator, audible alerts and factory reset.

An internal 32kHz low-power oscillator is available by default for non-critical timing requirements. Applications requiring an accurate real-time clock may connect an (optional) external 32kHz crystal.

All versions of the module have Bluetooth BQB SIG certification, and FCC & IC modular approval for use in the United States and Canada, and CE approval for use in Europe and other countries.

C interface

Each module provides an extensive array of I/O and peripheral interfaces. The following list of interfaces are available, many of which are accessible with I/O multiplexing and alternate function capabilities.

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, 512xkbyte serial flash and a PCB-style antenna. The AMS001 version also includes a high-efficiency DC-DC switching regulator to significantly reduce active mode power consumption.

The Bluetooth SoC is powered by an ARM Cortex M3based 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 512 kByte 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 integration into end products.

An extensive array of analog and digital peripherals including ADCs, GPIOs, PWMs and multiple serial interfaces such as UART, SPI and I2C are accessible via module pins.

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

3.1 Absolute Maximum Ratings

CAUTION! The absolute maximum ratings in Table 1 and Table 2 indicate levels where permanent damage to the device can occur, even if these limits are exceeded for only a brief duration. Functional operation is not guaranteed under these conditions. Operation at absolute maximum conditions for extended periods can adversely affect longterm reliability of the device.

Table 1. Absolute Maximum Voltage Ratings

Table 2. Absolute Maximum Environmental Ratings

3.2 Recommended Operating Conditions

Functional operation is not guaranteed outside the limits shown in Table 3 and Table 4, and operation outside these limits for extended periods can adversely affect long-term reliability of the device.

DC Operating Conditions

Notes:

1. Overall performance degrades beyond minimum and maximum supply voltages.

2. The module may fail to boot if this condition is not met when power is initially applied.
