1 PRODUCT OVERVIEW

INTRODUCTION

This user’s manual describes SAMSUNG's SC32442B 16/32-bit RISC microprocessor. SAMSUNG’s SC32442B

is designed to provide hand-held devices and general applications with low-power, and high-performance micro-

controller solution in small die size. To reduce total system cost, the SC32442B includes the following

components.

The SC32442B is developed with ARM920T core, 0.13um CMOS standard cells and a memory complier. Its low-

power, simple, elegant and fully static design is particularly suitable for cost- and power-sensitive applications. It

adopts a new bus architecture known as Advanced Micro controller Bus Architecture (AMBA).

The SC32442B offers outstanding features with its CPU core, a 16/32-bit ARM920T RISC processor designed by

Advanced RISC Machines, Ltd. The ARM920T implements MMU, AMBA BUS, and Harvard cache architecture

with separate 16KB instruction and 16KB data caches, each with an 8-word line length.

By providing a complete set of common system peripherals, the SC32442B minimizes overall system costs and

eliminates the need to configure additional components. The integrated on-chip functions that are described in

this document include:
