DESCRIPTION

The LH79520, powered by an ARM720T, is a complete System-

on-Chip that breaks the cost/performance barrier with a high level of

integration to satisfy a wide range of requirements and expectations. The

LH79520 combines a 32-bit ARM7TDMI RISC, 8KB Cache, MMU, color

LCD controller, and local SRAM. Also included are a number of essential

peripherals such as a DMA Controller, Serial and Parallel Interfaces, Infra-

red Support, Counter/Timers, Real Time Clock, Watchdog Timer, Pulse

Width Modulators, and an on-chip Phase Lock Loop.

This high level of integration lowers overall system cost, reduces

development cycle time and accelerates product introduction. Featuring

5 V tolerant inputs, the LH79520’s fully static design, power management

unit, low voltage operation (1.8 V Core, 3.3 V Input/Output), on-chip

PLL, and very low power RISC core provide high performance at a low

current draw.
