MSM7712
Wireless LAN Baseband Controller
DESCRIPTION
The MSM7712 is the first release in a series of wireless LAN baseband controllers, designated .XI (a suffix
of the IEEE P802.11 protocol). The MSM7712 integrates the baseband physical layer and the lower MAC
layers into a single IC that supports specific draft standards of the P802.11 specification. The architecture
targets optimum integration with maximum user flexibility, providing a migration path to low-cost mod-
ule handsets and access points. In accordance with all three P802.11 media, the MSM7712 directly sup-
ports frequency hopping (FH), spread spectrum, direct-sequence spread spectrum, and infrared
protocols., A board-level system contains the MSM7712, a radio, a 16-bit processor, and buffer memory
ICs.
The MSM7712 provides a seamless interface to the radio, hoist, processor, and memory subsystems. The
device directly interfaces with the PCMCIA R2.1 and ISA bus, with support for 16-bit data transfers. The
device can control antenna select, synthesizer programming, and power-save modes. The MSM7712 pro-
vides FH PLPC framing, with the FH modem on-board. A bypass mode allows support for other stan-
dards. MSM7712 firmware is available from Oki Semiconductor.
Portable handheld systems inherently require minimal current dissipation during operation and standby
modes. The MSM7712 offers low power consumption via its implementation of a 3-V core. Either 3-V or
5-V I/O are available for optimal RF and host-interface design.
The MSM7712 wireless LAN baseband controller is manufactured in Oki鈥檚 advanced Si-gate 0.5
