7. PSoC 64 reset button (SW1): This button is used to reset the PSoC 64 device. This button
connects the PSoC 64 reset (XRES) pin to ground when pressed.
8. Cypress 512-Mbit Semper NOR flash memory (S25HL512T, U6): An S25HL512TFABHI010
NOR flash of 512-Mbit capacity is connected to the serial memory interface (SMIF) of the PSoC
64 device. The NOR device can be used for both data and code memory with execute-in-place
(XIP) support and encryption.
9. PSoC 64 I/O headers (J1, J2): These headers provide connectivity to PSoC 64 GPIOs. Many of
these I/Os are also connected to on-board peripherals.
10. PSoC 64 user LEDs (LED3, LED4): The red LED (LED3) can operate at the entire operating
voltage range of the PSoC 64 chip, whereas the green LED (LED4) works only at 2.5 V and
higher. Both LEDs are active LOW, so the pins must be driven to ground to turn ON the LED.
11. PSoC 64 chip (CYB06445LQI-S3D42, U1): CYB06445LQI-S3D42 is a PSoC 64 "Secure Boot
MCU" with 448 KB of flash and 152 KB of SRAM available for user applications. The chip
features out-of-the-box security functionality, providing an isolated root-of-trust with true
attestation and provisioning services.
12. PSoC 64 program and debug header (J9): This 10-pin header allows you to program and
debug the PSoC 64 chip using an external programmer such as MiniProg4. Note that this is not
loaded by default.
13. PSoC 64 USB device connector (J4): The USB cable provided with the Prototyping Kit can
also be connected between this USB connector and the PC to use the PSoC 64 USB device
functionality in your applications.
14. System Power selection jumper (J3): This jumper is used to select the PSoC 64 supply
voltage (P6.VDD) between three voltages: 1.8 V, 2.5 V, and 3.3 V. It must be set to 2.5 V during
provisioning.
15. PSoC 64 user button (SW2): This button can be used to provide an input to the PSoC 64
device. Note that by default, the button connects the PSoC 64 device pin to ground when
pressed, so you need to configure the PSoC 64 pin as a digital input with resistive pull-up for
detecting the button press. This button can also provide a wake-up source from low-power
modes of the device.
16. PSoC 64 current measurement header (J6): This header can be used to measure the current
consumption of the PSoC 64 using an ammeter. It is not loaded by default and is bypassed using
a zero-ohm resistor across the two pins.
