LM3S6965-IQC50-A2

Product Summary

The Stellaris
?
family of microcontrollers—the first ARM? Cortex?-M3 based controllers—brings
high-performance 32-bit computing to cost-sensitive embedded microcontroller applications. These
pioneering parts deliver customers 32-bit performance at a cost equivalent to legacy 8- and 16-bit
devices, all in a package with a small footprint.
The Stellaris
?
family offers efficient performance and extensive integration, favorably positioning
the device into cost-conscious applications requiring significant control-processing and connectivity
capabilities. The Stellaris
?
LM3S6000 series combines both a 10/100 Ethernet Media Access Control
(MAC) and Physical (PHY) layer , marking the first time that integrated connectivity is available with
an ARM Cortex-M3 MCU and the only integrated 10/100 Ethernet MAC and PHY available in an
ARM architecture MCU.
The LM3S6965 microcontroller is targeted for industrial applications, including remote monitoring,
electronic point-of-sale machines, test and measurement equipment, network appliances and
switches, factory automation, HV AC and building control, gaming equipment, motion control, medical
instrumentation, and fire and security .
For applications requiring extreme conservation of power, the LM3S6965 microcontroller features
a battery-backed Hibernation module to efficiently power down the LM3S6965 to a low-power state
during extended periods of inactivity . With a power-up/power-down sequencer , a continuous time
counter (RTC), a pair of match registers, an APB interface to the system bus, and dedicated
non-volatile memory, the Hibernation module positions the LM3S6965 microcontroller perfectly for
battery applications.
In addition, the LM3S6965 microcontroller offers the advantages of ARM's widely available
development tools, System-on-Chip (SoC) infrastructure IP applications, and a large user community .
Additionally , the microcontroller uses ARM's Thumb?-compatible Thumb-2 instruction set to reduce
memory requirements and, thereby , cost. Finally , the LM3S6965 microcontroller is code-compatible
to all members of the extensive Stellaris
?
family; providing flexibility to fit our customers' precise
needs.
T exas Instruments offers a complete solution to get to market quickly , with evaluation and
development boards, white papers and application notes, an easy-to-use peripheral driver library ,
and a strong support, sales, and distributor network. See “Ordering and Contact Information” on page
