PRODUCT OVERVIEW
SAM87 RC PRODUCT FAMILY
Samsung's new SAM87RC 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. Timer/counters with selectable operating modes are included to support real-time operations. Many SAM87RC 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.
KS88C4504 MICROCONTROLLER
The KS88C4504 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM87RC 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 KS88C4504 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 SAM87RC modular design approach, the following peripherals were integrated with the SAM87RC CPU core: — Five configurable 8-bit general I/O ports — One 2-bit general I/O ports — Full-duplex serial data port with one synchronous operating modes — Two 8-bit timers with interval timer — Two 16-bit timers/counters with PWM operating modes or capture modes — One voltage level detector pin — Four embedded chip selection pins (CS0–CS4) or normal I/O ports — Two programmable 8-bit PWM modules with corresponding output pins — A/D converter with 4 selectable input pins
OTP
The KS88C4504 microcontroller is also avaiable in OTP(One Time Programmable) version, KS88P4504 The KS88P4504 microcontroller has an on-chip 4K-byte one-time-programable EPROM instead of masked ROM. The KS88P4504 is comparable To KS88C4504, both in function and in pin configuration.
