S3C8444

The S3C8444 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM8 CPU core. Stop and Idle power-down modes of S3C8444 were implemented to reduce power consumption. The size of the internal register file is logically expanded, increasing the addressable on-chip register space to 1040 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of program and data memory. The S3C8444 is a versatile microcontroller that is ideal for use in a wide range of general-purpose applications such as CD-ROM/DVD-ROM drives.

Using the SAM8 modular design approach, the following peripherals of S3C8444 were integrated with the SAM8 CPU core:
  - Six configurable 8-bit general I/O ports
  - One 8-bit n-channel, open-drain output port
  - One 8-bit input port for A/D converter input or digital input
  - Full-duplex serial data port with one synchronous and three asynchronous (UART) operating modes
  - Two 8-bit timers with interval timer or PWM mode
  - Two 16-bit timer/counters with four programmable operating modes
  - Two programmable 8-bit PWM modules with corresponding output pins
  - One 8-bit capture module with CAP input pin
  - A/D converter with 8 selectable input pins

The S3C8444 is a versatile microcontroller that is ideal for use in a wide range of general-purpose ROM-less applications such as CD-ROM/DVD-ROM drivers.
