KS86C4004/C4104 MICROCONTROLLER

The KS86C4004/C4104 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM87Ri CPU core. The KS86C4004/C4104 is a versatile microcontroller, with its A/D converter and a zero-crossing detection capability it can be used in a wide range of general purpose applications. Stop and Idle power-down modes were implemented to reduce power consumption. To increase on-chip register space, the size of the internal register file was logically expanded. The KS86C4004/C4104 has 4-Kbytes of program memory on-chip (ROM) and 208-bytes of general purpose register area RAM.

Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core:

— Four configurable I/O ports (KS86C4004: 22 pins, KS86C4104: 16 pins)
— Six interrupt sources with one vector and one interrupt level
— Two 8-bit timer/counter with various operating modes
— Analog to digital converter (KS86C4004: 8-bit, 8-channel, KS86C4104: 10-bit, 5-channel)
— One zero cross detection module
