Bus Architecture
33
I2C-bus – parallel vs serial
Commonly described as “Two-wire bus”
One wire for data, one wire for clock
Serial bus to conserve pins (versus parallel)
Master-Slave hierarchy for simplicity
Good for low to medium speed applications (< 1 MHz)
I2C = Inter-IC
Parallel
V
CC
Logic
Costs EMC, interconnects and pins
Saves PCB space
Lot of programming
Easily expandable
Lots of wires
Better results, no hassle

Comments about Inductor Boost
Inductor size is large, but PCB area is primarily dominated by the size
of the LED layout area
Having multiple LEDs not only gives Xenon Flash physical
resemblance, but driving them by one output provides more and uniform
output light, resulting in taking high quality picture
YES
TX_MASK reducing output current, prevents over-draining battery in
push application such as downloading email
Separate LED indictor output for video-on
* One additional rectifying diode is required for asynchronous converter
Inductor boost converter that extends battery life in flash or video mode, is critical for high performance
camera phone
Driving single and multiple LED allows one inductor boost converter to use across multiple platforms
Having multiple LEDs not only gives Xenon Flash physical resemblance, but driving them by one output
allows inductor boost converter provides more and uniform output light, resulting in high quality picture
