Key components
Dual-band 802.11ac-friendly radio with Bluetooth
®
5.0
This radio is purpose-built for IoT applications. This radio is a 28-nm, ultra-low-power device that integrates a
single-stream, dual band IEEE 802.11n-compliant, IEEE 802.11ac-friendly Wi-Fi sub-system, a Bluetooth
®
5.0-compliant Bluetooth
®
sub-system, and an advanced coexistence engine for maximum combined perfor-
mance. The 28-nm architecture enables dual band 802.11ac-friendly with Bluetooth
®
5.0 radio to offer
best-in-class power consumption in active and power saving modes. 802.11ac-friendliness enables the radio to
guarantee superior performance in terms of throughput and power consumption compared to 802.11n products
when operating in 802.11ac networks.
Crystal and oscillators
The CYSBSYS-RP01 system has an on-board 32.768-kHz oscillator shared between PSoC
®
6 MCU and the radio.
The 32.768-kHz oscillator is used by PSoC
®
6 MCU for the WCO block for Deep sleep operation for low-power-mode
timing.
Chip antenna for Wi-Fi and Bluetooth
®
The system has an ultra-miniature chip antenna that supports 5-GHz and 2.4-GHz bands. The selected antenna
has an efficiency of up to 51% at 2.4 GHz at 48% for 5 GHz. See
for optimal placement of the
CYSBSYS-RP01 board, and antenna efficiency details for different host board layouts.
CAPSENSE
®
external modulation and integration capacitors
To enable CAPSENSE
®
use cases on end applications, PSoC
®
6 MCU requires an external CMOD capacitor
(modulator capacitor) for self-capacitance sensing, and CINTA and CINTB (integration capacitors) for mutual
capacitance sensing. These external capacitors are connected between a dedicated GPIO pin and ground.
