4 Technical Descriptions
4.1. Main Board
4.1.1. CPU Block
CPU (IC101)
Operating Power Supply: 3.3V (for I/O) 1.2V (for Core)
Package: 344 pin LGA
Outline of Operation: This LSI encodes a picture signal input from a camera into a JPEG or an MPEG4 format and an audio sig-
nal input from a microphone into a G726 format, and then it distributes the data to the terminal on the IPV4 or IPV6 network
using the network server function achieved by processing the software of a built-in processor.
CMOS sensor (IC701) and Real Time Clock IC (IC3) on the Lens Board are accessed by I2C I/F. Ethernet PHY (IC105) is
accessed by MII (Media Independent Interface) I/F.
FLASH MEMORY (IC102)
Operating Power Supply: +3.3V
Package: 48 pin Ball DGA
Capacity: 64Mbit
Access Time: 60ns
Outline of Operation: Stores programs for CPU operation, MAC address and customer setup data. Version up is available from
Ethernet I/F.
SDRAM (IC103,IC104)
Operating Power Supply: +3.3V
Package: 54 pin TSOP
Capacity: 64Mbit
Outline of Operation: Stores the memory for CPU work and temporary saved images.
RESET IC (IC106)
Reset voltage: 2.9V
Package: 4 pin SOP
Outline of Operation: When 3.3V power starts up, it emits about 150ms reset pulse after detecting 2.9V.
Clear Setting Button (SW802)
Outline of Operation: It is possible to bring back the setting value of a Network Camera to a factory-shipments state, when you
push.
