The evaluation board is for testing purposes only and, because it has limited functions and
limited resilience, is not suitable for permanent use under real conditions. If the evaluation board is
nevertheless used under real conditions, this is done at one’s responsibility;

Hardware
Microcontroller
Automotive PSoC® 4 MCU platform has an AEC-Q100 qualification established by
Automotive Electronics Council (AEC).
32-bit MCU subsystem includes:
•48-MHz Arm Cortex-M0+ CPU.
•Up to 384 KB of flash with accelerator, coupled to the CPU to improve average access
times from the flash block.
•Up to 32 KB of SRAM with zero wait-state access at 48 MHz.
•16-channel Direct Memory Access engine.
CapSense is supported on all pins in PSoC 4100S Max via a Multi-Sensing Converter
that can be connected to any pin via the Analog Mux Busses that any GPIO pin can be
connected to.
Programming Using External Connector
Users may use third-party programming devices to connect the CY8C4149AZE-S598
target via the P11 SWD connector. The onboard “KitProg3” debugger should not be powered
while using an external JTAG connector.
Power Sources
There are four ways to provide power for the MCU in RDK4:
1. KitProg3 USB Type-C port 5.5V maximum.
2. Arduino connector P3 pin 8 [VIN] 26V maximum.
3. VS AUX header P2 26V maximum.
4. Battery banana sockets J1 and J4 26V maximum.

Power Distribution Diagram
Select the main power supply using SW4 –the KitProg3 USB Type-C port USB or the
3.3V System Basis Chip VCC1 LDO output.
Insertion and Extraction of Wire from AVX 9296 Connectors
The RDK4 board has two AVX 9296 2-pin connectors for the Li-ion battery and load
connection (P13 and P6). The 20/22/24/26AWG wires are recommended to be striped from
3.5mm to 4.5mm before insertion. Once inserted it can be extracted without any tools. Gently
rotate the wire while pulling until the extraction is complete. Please refer to the application note
201-01-167 provided by the AVX for more detailed information.
