SAM87RI PRODUCT FAMILY
Samsung's SAM87RI family 8-bit single-chip CMOS microcontrollers offers fast efficient CPU, wide range integrated peripherals, various mask-programmable sizes. dual address/data architecture large number bit- nibble-configurable ports provide flexible programming environment applications with varied memory requirements. Timer/counters with selectable operating modes included support real-time operations. Many SAM87RI microcontrollers have external interface that provides access external memory other peripheral devices.
KS86C0004/P0004/C0104/P0104 MICROCONTROLLER
KS86C0004/P0004/C0104/P0104 single-chip 8-bit microcontroller fabricated using advanced CMOS process. built around powerful SAM87RI core. Stop Idle power-down modes were implemented reduce power consumption. increase on-chip register space, size internal register file logically expanded. KS86C0004/P0004/C0104/P0104 bytes program memory on-chip. Using SAM87RI design approach, following peripherals were integrated with SAM87RI core: Five configurable ports pins) bit-programmable pins external interrupts 8-bit timer/counter with three operating modes KS86C0004/P0004/C0104/P0104 versatile microcontroller that used wide range general purpose applications. especially suitable keyboard controller available 40-pin 44-pin package.
KS86C0004/C0104 microcontroller also available (One Time Programmable) version, KS86P0004/P0104. KS86P0004/P0104 microcontroller on-chip 8-Kbyte one-time-programmable EPROM instead masked ROM. KS86P0004/P0104 comparable KS86C0004/C0104, both function configuration.
