DESCRIPTION
The advent of 3G technology opens up a wide range
of multimedia applications in mobile information appli-
ances. The LH7A404 is designed from the ground up
with a 32-bit ARM922 Core to provide high processing
performance, low power consumption, and a high level
of integration. Features include 80 kB on-chip SRAM,
fully static design, power management unit, low voltage
(1.8 V Core, 3.3 V I/O) and on-chip PLL.
NOTE: Devices containing lead-free solder formulations have differ-
ent reflow temperatures than leaded-solder formulations.
When using both solder formulations on the same PC board,
designers should consider the effect of different reflow tem-
peratures on the overall PCB assembly process. (Refer to
www.nxp.com for an application note on recommended
soldering practices).
