PRODUCT OVERVIEW
1.1 OVERVIEW
Samsung's S3C2501X 16/32-bit RISC microcontroller is a cost-effective, high-performance microcontroller
solution for Ethernet-based systems, for example, SOHO router, internet gateway, WLAN AP, etc.
A variety of communication features are embedded into S3C2501X required in many communication areas,
including two Ethernet MACs, a high speed UART, and a console UART. A security feature is also supported by
DES/3DES accelerator.
This highly integrated microcontroller enables customers to save system costs and increase performance
over other 32-bit microcontroller.
The S3C2501X is built based on an outstanding CPU core: The ARM940T cached processor is a member of the
ARM9 Thumb family of high-performance 32-bit system-on-a-chip processor solutions.
It provides a complete high performance CPU subsystem, including ARM9TDMI RISC integer CPU, 4KB
instruction/data caches, write buffer, and protection unit, with an AMBA bus interface.
The ARM9TDMI core within the ARM940T executes both the 32-bit ARM and 16-bit Thumb instruction sets,
allowing the user to trade off between high performance and high code density.
It is binary compatible with ARM7TDMI, ARM10TDMI, and Strong ARM processors, and is supported by a wide
range of tools, operating systems, and application software.
The following integrated on-chip functions are described in detail in this user's manual :
•
