Description

20-pin WL-CSP

28-pin SSOP

1, 7, 14, 22, 28

GND

Ground

RSTN

Reset Input. Pull this pin to logic low to reset all control registers (set to default

values). For normal operation pull this pin to VDD.

ADDR

I²C Address. Connect to external resistor for I²C address selection. Up to 8

devices can be connected on one bus. (see Table 6 on page 12)

SDA

Serial-Data I/O. Open drain digital I/O I²C data pin.

SCL

Serial-Clock Input

3, 10, 18, 19, 26

VDD

Positive Supply Voltage. Connect to a +2.7V to +5.5V supply. Bypass this pin

with 10 F capacitance to GND.

SYNC

Synchronization Clock Input or Output. The SYNC frequency for Input and

Output is 1MHz. For SYNC_OUT the frequency can be reduced to 32kHz.

IRQ

Interrupt Request. Programmable Open drain digital Output. It can be set via

an register after which event (Interface Timeout, POK, CP_Request, Error

Detection, End of Frame or End of Movie) the pin triggers an Interrupt Request.
