CY8CMOD-064B0S2-4343W (MOD1)
CY8CMOD-064B0S2-4343W is a castellated PCB module which consists mainly of PSoC 64 chip
and CYW4343W devices. The module also houses a 2.45 GHz/5.5 GHz dual-band chip antenna, RF
switch for antenna diversity, Low Power Oscillator (LPO) for CYW4343W, crystal oscillators for
PSoC 64, modulation and integration capacitors to support CapSense and other passive
components required for the proper working of PSoC 64 and CYW4343W. A pre-certified Type 1DX
module with CYW4343W from Murata, LBEE5KL1DX, is used for ease of development. CYW4343W
supports only the 2.45 GHz band, but the antenna used is a 2450AD14A5500 Dual Band 2.45 GHz/
5.5 GHz Mini Chip Antenna from Johanson, to use the same antenna across different designs. The
castellated PCB module has 137 castellated pads, which are used for different voltage rails and I/O
signals of the PSoC 64 device and the CYW4343W.
