S3F441FX

SAMSUNG S3F441FX 16/32-bit RISC micro-controller is a cost-effective and high-performance solution for HDD and general purpose applications.

An outstanding feature of the S3F441FX is its CPU core, a 16/32-bit RISC processor (ARM7TDMI) designed by Advanced RISC Machines, Ltd. The ARM7TDMI core is a low-power, general-purpose, microprocessor macrocell which was developed for the use in application-specific and customer-specific integrated circuits. Its simple, elegant, and fully static design is particularly suitable for cost-sensitive and power-sensitive applications.

The S3F441FX has been developed by using the ARM7TDMI core, CMOS standard cell, and data path compiler. Most of the on-chip function blocks have been designed by using a HDL synthesizer. The S3F441FX has been fully verified in SAMSUNG ASIC test environment including internal Qualification Assurance Process.

By providing a complete set of common system peripherals, the S3F441FX can minimize the overall system costs and eliminate the need to configure additional components, externally.

The integrated on-chip functions which are described in S3F441FX include:

  - Memory system manager: 3 external memory banks. (If the internal flash ROM is not used for
      a boot code, nCS0 will be used for a boot ROM )
  - Built-in 256Kbyte (64K x 32bit) Flash memory
  - 8K-bytes (2K x 32bit) internal SRAM for stack, data memory, and/or code memory
  - One channel UART
  - Six 16-bit internal timers with 8-bit pre-scaler and input Capture function
  - Power down mode: STOP and IDLE modes
  - One 8-bit basic timer and 3-bit watch-dog timer
  - Interrupt controller (Total of 19 interrupt sources including 3 external sources )
  - Sixteen programmable I/O ports
  - On-chip PLL
  - 64-pin LQFP
