Figure 4-1. System Block Diagram
This board includes a custom LCD glass with maximum 128 segments. The glass has 24 pins (8
common and 16 segments lines) that are routed to the 20 × 2 pin connector and connected to the
configured I/O pins of PSoC.
I2C EEPROM is a ‘No Load’ component on the board. It is used to store information about the EBK
board number, so PSoC can recognize the board. ST M24C02-W is the 2-Kbit EEPROM with
operating voltage in the range 2.5 V to 5.5 V.
40-pin (20 × 2) connector helps to connect the configured PSoC I/O pins to the LCD glass pins.
From the 40 pins available, only 24 are used by the kit. All unused pins are left floating.
