PRELIMINARY
CYSBSYS-RP01
There are five major subsystems:
■ PSoC 6 MCU
■ Single-chip, ultra-low-power, IEEE 802.11n-compliant, IEEE 802.11ac-friendly Wi-Fi with Integrated Bluetooth
®
5.0 radio
■ Crystal and oscillators
■ Chip antenna for Wi-Fi / BT and u.FL connector
■ CapSense
®
external modulation and integration capacitors and other passives like bypass capacitors and limiting resistors.
PSoC 6 MCU
The PSoC 6 MCU product family, based on an ultra-low-power 40-nm platform, is a combination of a microcontroller with low-power
flash technology and digital programmable logic, high-performance analog-to-digital and digital-to-analog conversion, low-power
comparators, and standard communication and timing peripherals.
Dual-band 802.11ac-friendly Radio with BT 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 BT sub-system, and an advanced
coexistence engine for maximum combined performance. The 28-nm architecture enables dual-band 802.11ac-friendly with BT 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 onboard 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 / BT and u.FL Connector
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
“Recommended Host PCB Layout” on page 7 for optimal placement of the CYSBSYS-
RP01 board, and antenna efficiency details for different host board layouts.
An additional footprint for a u.FL connector is also provided on board; this is used to connect an external antenna. See
“Ordering
Information”
on page 22 for CYSBSYS-RP01 board variants with u.FL connector.
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.
