As someone already pointed out, the WIC-4ESW is only supported on 1700 routers.

On 3640 You have option of using NM-16ESW, which is 16 ports 10/100
switch. You'll need IP Plus feature-set. The switching is wire-speed,
inter-VLAN routing will depend on Your CPU resources. Of course You
can do rate-limiting etc. on logical VLAN interfaces.

Considering the cost of NM-16ESW, You can go for either Cat2940,
which won't route, has only 8 ports, can be configured to
do trunking (802.1Q only) and is almost twice cheaper, or buy entire
router (!) cheaper than the network module - 1711 or 1712. It has
WIC-4ESW integrated, along with mounted fifth FastEthernet, and either
analog or ISDN BRI WIC. It has also VPN module, 96MB RAM and software
with firewall, IDS and VPNs. It may be the wisest and most
flexible solution.
