2.4 Firmware Upload
When iMCU7100EVB is purchased, the LOOPBACK_TCPS Firmware is included in the CD. If user wants to
use a Firmware other than this, (ex: Firmware created by user) the corresponding Firmware can be
uploaded by using WizISP or the W7100 Debugger Program. Please refer to WizISP user’s guide and
W7100 Debugger user’s guide for more details on WizISP and W7100 Debugger program.

Table 3.1 Parts Description of iMCU7100EVB
3.1 iMCU W7100 (U1)
The W7100 is the one chip solution which includes an 8-bit internet microcontroller unit (iMCU),
embedded 8051 compatible MCU core, and a hardwired TCP/IP core.
zPlease refer to W7100 datasheet for more detail.
3.2 Ethernet Port (P1)
Ethernet Port (P1) is the connector that connects the UTP cable; and is structured of an internal RJ-45
connector with a transformer to connect iMCU7100EVB board to the network.
3.3 RS-232C Serial Port (P2, J11)
RS-232C Serial Port (P2, J11) is a serial interface supported by W7100. RS-232C Serial Port is basically
structured to use DSUB 9Pin Male type connector (P2). But RS-232C Serial Port is also structured to
independently connect three pin of TX/RX/GND, which are TTL signals, with the Pin header; allowing
the user to use user-produced cable. Fig.3.2 shows the structure.
