BMD-100 Module for Bluetooth 4.1 LE
The BLUMOD BMD-100 is a Bluetooth Smart master/slave network
processor module targeted for low-power sensors and accessories
using the ultralow power STMicroelectronics BlueNRG-MS chipset.
It integrates features required for a Bluetooth Smart application,
including Bluetooth radio, software stack, and GATT/ATT-based
access. The external host application processor, where the
application resides, connects using SPI20. This allows the best
microcontroller for the application to be chosen and C based
Bluetooth Low Energy profiles are available for compiling into your
application.
The module can be powered directly from a standard 3V coin cell
battery or a pair of AAA batteries with a maximum input current of
only 15 mA at the highest output power. On-module flash memory
allows in the field Bluetooth low energy stack upgrades.

The application controller interface (ACI) uses a standard SPI slave interface as the transport
Layer on five physical wires:
2 control wires (clock and slave select)
2 data wires with serial shift-out (MOSI and MISO) in full duplex
1 wire to indicate data availability from the slave
All the SPI pins have an internal pull-down except for the SPI_CS that has a pull-up. All the SPI
pins, except the SPI_CS, are in high impedance state during the low-power states. The SPI_IRQ pin
requires an external pull-down resistor.

7.4. Clocks
The BMD-100 integrates two low-speed frequency oscillators (LSOSC) and two high-speed
(32 MHz) frequency oscillators (HSOSC).

BMD-100-DS-V0.5 PRELIMINARY Page 7 of 17
The primary high frequency clock is a 32 MHz crystal oscillator. There is also a fast starting 12 MHz ring
oscillator that provides the clock while the crystal oscillator is starting up. Frequency tolerance of the high-
speed crystal is ±30 ppm.
The low frequency clock is used in Low Power mode and can be supplied either by a 32.7kHz oscillator that
uses an external crystal and guarantees up to ±50 ppm frequency tolerance, or by a ring oscillator with
maximum ±500 ppm frequency tolerance, which does not require any external components.

11. RF Design Notes
11.1. Recommended RF Layout & Ground Plane
The integrated ceramic chip antenna requires a suitable ground plane to radiate effectively. Reducing the
ground plane from that shown in figure 7 will reduce the effective radiated power.
The BMD-100 module should be placed at the edge of the ground plane with the antenna side towards the
edge. Place a copper keep-out under the antenna (area shown in red). The area under the keep-out and
extending out from the edge of the ground plane should be kept clear of copper and other metal. The BMD-
100 uses a Johanson Technology 2450AT07A0100 chip antenna. Additional information on the antenna can be
acquired from www.johansontechnology.com.

11.2. Mechanical Enclosure
Care should be taken when designing and placing the module into an enclosure. Metal should be kept clear
from the antenna area, both above and below. Any metal around the module can negatively impact RF
performance.
The module is designed and tuned for the antenna and RF components to be in free air. Any potting, epoxy fill,
plastic overmolding, or conformal coating can negatively impact RF performance and must be evaluated by
the customer.
