DESCRIPTION
The LH79520, powered by an ARM720T, is a com-
plete System-on-Chip with a high level of integration to
satisfy a wide range of requirements and expectations
.
The LH79520 combines a 32-bit ARM720T RISC,
Color LCD controller, Cache, Local SRAM, a number of
essential peripherals such as Direct Memory Access,
Serial and Parallel Interfaces, Infrared support, Timers,
Real Time Clock, Watchdog Timer, Pulse Width Modu-
lators, and an on-chip Phase Lock Loop. Debug is
made simple by JTAG support.
This high level of integration lowers overall system
costs, reduces development cycle time and acceler-
ates product introduction. The LH79520’s fully static
design, power management unit, low voltage operation
(1.8 V Core, 3.3 V I/O, 1.8 V optional*), on-chip PLL,
fast interrupt response time, on-chip cache and SRAM,
powerful instruction set, and low power RISC core pro-
vide high performance.
To build an advanced portable device, advanced pro-
cessing capability is required. This capability must come
with increased performance in the display system and
peripherals, and yet demand less power from batteries.
The LH79520 is an integrated solution to fit these needs.
