KS88C4404 MICROCONTROLLER
The KS88C4404 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 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 KS88C4404 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 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 KS88C4404 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.
