1.1 INTRODUCTION
Samsung's S3F401F 16/32-bit RISC microcontroller is a cost-effective and high-performance microcontroller
solution for an inverter motor and a general-purpose application.
An outstanding feature of the S3F401F is its CPU core, a 16/32-bit RISC processor (ARM7TDMI-S) designed by
Advanced RISC Machines, Ltd. The ARM7TDMI-S core is a low-power, general purpose, microprocessor macro-
cell, 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 application. Using the
ARM7TDMI-S core, CMOS standard cell, and a data path compiler has developed the S3F401F. Most of the on-
chip function blocks have been designed using an HDL synthesizer
The integrated on-chip functions, which are described in this document include:
• Built-in 256Kbyte NOR-Flash memory
• Internal
20K byte SRAM for stack, data memory, or code memory
• Interrupt controller: 90 interrupt sources, interrupt priority control logic and interrupt vector generation by H/W.
• Three programmable I/O port groups
• Two inverter timer, Two channel 16bit encoder counter,
having PHASE A,B and Z
• Two-channel UART, Two-channel SSP
• Six-channel 16-bit timers with capture and PWM
• Fifteen-channel 12-bit ADC
• One-channel 8-bit basic timer and 3-bit watch-dog timer
• Crystal/Ceramic oscillator or external clock can be used as the clock source and PLL
• Power control: Normal, Idle, and Stop mode
• Clock monitor
