Power supply sub system

Power supply inputs

The power supply system on this board is versatile, allowing the board to be supplied from any of the following sources:

  • 5 V input from on board KitProg3 Type-C USB connector ( J1 )

  • 5 V input from the PSOC™ Edge E84 MCU Type-C USB connector ( J2 )

  • 3 V - 5 V from the external/Battery power input connector ( J3 ) - by default this connector is not populated

PSOC™ Edge E84 MCU clock sources

The PSOC™ Edge E84 AI kit is designed to support advanced applications with its hardware features. It includes a

24 MHz

external clock source from a crystal oscillator (

Y3

) connected to

P7[4]

as primary clock source. A

17.2032 MHz

clock source from a crystal (

Y1

) connected to

P19[0]

and

P19[1]

and a

32.768 KHz

clock source from crystal (

Y2

) is connected to

P18[0]

,

P18[1]

to enable the ECO (External Crystal Oscillator) and WCO (Watch Crystal Oscillator) modes of the PSOC™ Edge E84 MCU.

The external clock source and ECO mode is used for high-performance clock generation, which is crucial for applications that require fast processing speeds. The WCO mode, on the other hand, is used for low-power operation, allowing the device to run at reduced power consumption while still maintaining accurate timekeeping.

For USB functionality, it is recommended to use an external clock source for precise clock generation. This is because USB communication requires a stable and precise clock signal to ensure reliable data transfer. The external clock source can be connected to the PSOC™ Edge E84 MCU's USB clock input, providing the necessary clock signal for USB operation.

By utilizing these features, the PSOC™ Edge E84 AI kit provides high-performance clock generation, low-power operation, and reliable USB communication, making it suitable for advanced applications.

Reset and user buttons

This Kit contains one reset button (

SW2

) for resetting the PSOC™ Edge E84 MCU. When this

SW2

button is pressed, the

PE84_RST_L

line of the PSOC™ Edge E84 MCU is pulled to the ground, which in turn resets the target device. The

4.7K

pull-up resistor on the

PE84_RST_L

is populated on the kit.

Figure 42.

Schematic for Reset button interface



The board features a user button

SW1

, which serves as a general user input or for controlling different application states. The PSOC™ Edge E84 MCU pin

P7[0]

connected to user button

SW1

is pulled to the ground through a

1K

resistor when this button is pressed.

User LED's and Power LED's

The kit contains two discrete user LEDs:

LED1

(GREEN),

LED2

(BLUE), one user RGB LED (

LED3

)

and a power LED

LED5

(AMBER) for indication.

The power LED (

LED5

) indicates that the board is powered from either the on board KitProg3 Type-C USB connector (

J1

), PSOC™ Edge E84 Type-C USB connector (

J2

), or external power/battery input connector (
