WIZ820io is a new plug-in etwork module available from
Saelig that offloads Internet tasks to
a mini-board that includes WIZnet’s
popular W5200 IC (TCP/IP
hardwired chip + PHY), a mag-jack
(RJ45 with transformer), and other
peripheral logic. Housed in a very
small form factor ( 23 mm x 25 mm)
with two rows of 0.1” spaced pins,
WIZ820io can be used as a ready-made component for Internet-enabling a product or board, and is
an ideal solution for users who want
to develop networked systems
WIZ820io contains WIZnet’s
hardwired Ethernet stack IC W5200,
which supports eight independent
sockets simultaneously, and features
a high speed SPI interface, power-down mode, and Wake-On-LAN
function. WIZ820io handles TCP,
UDP, IP, ARP, ICMP, IGMP, PPPoE,
and MAC protocols.
WIZ820io operates at
temperatures from - 40 +85 deg C
on 3.3V/120 mA, but is 5V tolerant.
The module supports half/full duplex
operation, auto-negotiation, and auto
Off-loading the burden of the
TCP/IP stack into a second
peripheral chip (complete with
Ethernet MAC) can minimize product
debug issues and reduce time-to-market with TCP/IP stack problems
avoided. It also offers the additional
benefit of a more stable product,
with no possibility of stack overflows.
