The raw processing power of
this highly integrated system-
on-a-chip device enables
developers to create next-
generation networking
products that offer
tremendous channel
densities, while maintaining
system flexibility, scalability,
and upgradeability. The
MSC8102 is offered in two
core speed levels: 250 and
275 MHz.
What’s New?
Rev. 12 includes the following
changes:
• New Section 2.5.2 adds start-
up sequence timing.
The MSC8102 is a highly integrated system-on-a-chip that combines four StarCore™ SC140 extended cores with
an RS-232 serial interface, four time-division multiplexed (TDM) serial interfaces, thirty-two general-purpose
timers, a flexible system interface unit (SIU), and a multi-channel DMA engine. The four extended cores can
deliver a total 4400 DSP MMACS performance at 275 MHz. Each core has four arithmetic logic units (ALUs),
internal memory, a write buffer, and two interrupt controllers. The MSC8102 targets high-bandwidth highly
computational DSP applications and is optimized for wireless transcoding and packet telephony as well as high-
bandwidth base station applications. The MSC8102 delivers enhanced performance while maintaining low power
dissipation and greatly reducing system cost.
