Overview
Module Description
The CYBLE-212020-01 module is a complete module designed to be soldered to the applications main board.
Module Dimensions and Drawing
Cypress reserves the right to select components (including the appropriate BLE devi ce) from various vendors to achieve the BLE
module functionality. Such selections will still guarantee that all height restrictions of the component area are maintained. Designs
should be held within the physical dimensions shown in the mechanical drawings in Figure 1. All dimensions are in millimeters (mm).

Pad Connection Interface
Host PCB Keep Out Area Around Trace Antenna
As shown in the bottom view of Figure 1 on page 5, the CYBLE-212020-01 connects to the host board via solder pads on the backside
of the module. Table 2 and Figure 2 detail the solder pad length, width, and pitch dimensions of the CYBLE-212020-01 module.

Name Connections Connection Type Pad Length Dimension Pad Width Dimension Pad Pitch
SP 31 Solder Pads 1.02 mm 0.71 mm 1.27 mm
Figure 2. Solder Pad Dimensions (Seen from Bottom)
To maximize RF performance, the host layout should follow these recommendations:
1. The ideal placement of the Cypress BLE module is in a corner of the host board with the trace antenna located at the far corner.
This placement minimizes the additional recommended keep out area stated in item 2. Please refer to AN96841 for module
placement best practices.
2. To maximize RF performance, the area immediately around the Cypress BLE module trace antenna should contain an additional
keep out area, where no grounding or signal trace are contained. The keep out area applies to all layers of the host board. The
recommended dimensions of the host PCB keep out area are shown in Figure 3 (dimensions are in mm).

Power Supply Connections and Recommended External Components
Two Ferrite Bead Option
Single Ferrite Bead Option
Power Connections
The CYBLE-212020-01 contains two power supply connections,
VDD and VDDR. The VDD connection supplie s power for both
digital and analog device operation. The VDDR connection
supplies power for the device radio.
VDD accepts a supply range of 1.71 V to 5.5 V. VDDR accepts
a supply range of 1.9 V to 5.5 V. These specifications can be
found in Table 9. The maximum power supply ripple for both
power connections on the module is 100 mV, as shown in
Table 7.
The power supply ramp rate of VDD must be equal to or greater
than that of VDDR.
Connection Options
Two connection options are available for any application:
1. Single supply: Connect VDD and VDDR to the same supply.
2. Independent supply: Power VDD and VDDR separately.
Figure 7. Recommended Host Schematic Options for a Single Supply Option
External Component Recommendation
In either connection scenario, it is recommended to place an
external ferrite bead between the supply and the module
connection. The ferrite bead should be positioned as close as
possible to the module pin connection.
Figure 7 details the recommended host schematic options for a
single supply scenario. The use of one or two ferrite beads will
depend on the specific application and configuration of the
CYBLE-212020-01.
Figure 8 details the recommended host schematic for an
independent supply scenario.
The recommended ferrite bead value is 330 , 100 MHz. (Murata
BLM21PG331SN1D).
