KS88C4404 MICROCONTROLLER PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM8 PRODUCT FAMILY Samsung's new SAM8 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various mask-programmable ROM sizes. A dual address/data bus architecture and a large number of bit- or nibble-configurable I/O ports provide a flexible programming environment for applications with varied memory and I/O requirements. Timer/counters with selectable operating modes are included to support real-time operations. Many SAM8 microcontrollers have an external interface that provides access to external memory and other peripheral devices. The sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more interrupt sources and vectors. Fast interrupt processing (within a minimum six CPU clocks) can be assigned to specific interrupt levels. 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: 1–1 PRODUCT OVERVIEW KS88C4404 MICROCONTROLLER — 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.

XIN input high and low level width (tXH, tXL) Min – – 25 Typ – – – Max 20 10 500 Unit ms ms ns NOTE: Oscillation stabilization time (tST1) is the time required for the CPU clock to return to its normal oscillation frequency after a power-on occurs, or when Stop mode is ended by a signal. The RESET should therefore be held at low level until the tST1 time has elapsed (see Figure 15–3). 1 / fOSC1 tXL tXH XIN VDD – 0.5 V 0.4 V Figure 16–8.
