PCF85263ATL-ARD evaluation board
3.3 Static handling requirements
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care
should be taken during transport and handling. You must use a ground strap
or touch the PC case or other grounded source before unpacking or handling
the hardware.
3.4 Minimum system requirements
This evaluation board requires a Windows PC workstation. Meeting these minimum
specifications should produce great results when working with this evaluation board.
•
Computer with Windows 10
•
One USB port (either 3.0 or 2.0 or 1.1 compatible)
•
One of three EVK boards (MIMXRT1050-EVK, LPC55S69-EVK, 8MMINILPD4-EVK)
along with the associated firmware / GUI software
•
USB cable for power and data connection between PC and EVK board (if not included
in the EVK package)
4 Getting to know the hardware
4.1 PCF85263ATL-ARD features
•
Connector for external access to I
2
C-bus
•
On-board LED for interrupt pin monitoring
•
Equipped with Arduino Uno R3 port for direct connection with Arduino devices
•
Fully compliant with IMXRT1050 EVK board, including GUI (Windows 10)
•
Fully compliant with LPCXpresso55S69 dev. board, including GUI (Windows 10)
•
Compliant with i.MX Mini LPDDR4 EVK board, including GUI (Windows 10)
Note: For i.MX Mini LPDDR4 EVK Board is necessary to use IMX8MMINI-IARD
interposer board between the EVK and PCF85263ATL-ARD daughterboard (see
IMX8MMINI-IARD User Manual).
4.2 Kit featured components
identifies the main components on the board. The main elements are called out
in the picture. The Arduino port connectors (J5, J6, J35, J36) are located on the bottom
side of the board.
The board was developed around the DUT IC, PCF85263A (U1, see
.
). Using the Arduino interface, the board ca be attached to any device equipped with
Arduino port. The PCF85263ATL-ARD daughterboard communicates with the host
device or EVK, through an I
2
C-bus, with a maximum speed of 400 kHz. The I
2
C-bus is
linked to the dedicated pins of the Arduino connector (J35) and to on-board connector
(J38), allowing the user to access the I
2
C-bus from external. For more details about I
2
C
description and bus transactions, see PCF85263A datasheet (NXP Semiconductors).
The INTA/CLK output (pin 9) of PC85263A IC is connected to J5, pin 3. The on-
board LED (D2) can be connected through jumper header J24 to the interrupt line
