• 3.0–3.6V supply voltage with 5V tolerant inputs
TCP/IP Software
ZiLOG’s royalty-free TCP/IP Internet software
suite is an integrated, preemptive multitasking OS
and TCP/IP protocol stack that meets all of the rele-
vant RFCs. It is optimized for embedded systems
and is implemented as an extension to the ZiLOG
C-Compiler’s runtime library. Supported protocols
and network features are:
• TCP, UDP, IP, ARP, RARP, ICMP, IGMP, PPP
• FTP, SMTP, HTTP, TELNET, DNS
• TFTP, SNMP, DHCP/BOOTP, TIMEP
• In-system configuration or updates of network
parameters, web pages, and module firmware
A set of well-documented OS and network service
APIs allow system developers to quickly take
advantage of the ZiLOG TCP/IP software suite
while remaining focused on the main application.
Final binary output from the compiler/linker is the
complete user application with networking capabil-
ities across the Internet or any Intranet.
