MSM7730
Wireless LAN Baseband Controller
DESCRIPTION
The MSM7730 is Oki’s second generation of wireless local area network (LAN) baseband controllers des-
ignated “.XI” (a suffix of the IEEE P802.11 protocol). The MSM7730 integrates the baseband physical
layer (PHY) and the lower medium access controller (MAC) layers into a single device that supports the
IEEE 802.11 specification. The MSM7730 supports frequency hopping (FH), spread spectrum, direct-
sequence spread spectrum (DSSS), and infrared (IR) protocols.
Portable hand-held systems require minimal current dissipation during normal and standby modes. The
addition of new hibernate and smart-hibernate power-down modes lowers power consumption to 2 mA.
Two voltages are required for the MSM7730; 3.3 V for the core, and 5 V for the input/output (I/O) inter-
face.
The MSM7730 is manufactured using Oki’s advanced Si-gate 0.5µm complementary metal-oxide semi-
conductor (CMOS) process. MSM7730 firmware is available from Oki Semiconductor.
