DESCRIPTION
– MMC
The LH7A400, powered by an ARM922T, is a com-
plete System-on-Chip with a high level of integration to
satisfy a wide range of requirements and expectations.
– USB
• USB Device Interface (USB 2.0, Full Speed)
• Synchronous Serial Port (SSP)
– Motorola SPI™
This high degree of integration lowers overall
system costs, reduces development cycle time and
accelerates product introduction.
– Texas Instruments SSI
– National MICROWIRE™

NOTES:
1. Where ‘xx’ is a two digit revision number, e.g. B2; refer to
www.sharpmcu.com for a list of all the active revisions
2. Lead-free part
3. Devices containing lead-free solder formulations have different
reflow temperatures than leaded-solder formulations. When
using both solder formulations on the same PC board, designers
should consider the effect of different reflow temperatures on the
overall PCB assembly process.
