4.2.1
CY8CMOD-064S0S2-4343W (MOD1)
CY8CMOD-064S0S2-4343W is a castellated PCB module which consists mainly of PSoC 64 MCU
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 MCU, modulation and integration capacitors to support CapSense and other passive
components required for the proper working of PSoC 64 MCU 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 MCU and the CYW4343W.
For more information, see the
datasheet.
