Description

The KS86C4208 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM87Ri CPU core. The KS86C4204is a versatile microcontroller, with its A/D converter, SIO, IIC 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 pace, the size of the internal register file was logically expanded. The KS86C4208 have 4-Kbyte or 8-Kbyte 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 (24 pins)
• Nine interrupt sources with one vector and one interrupt level
• Two 8-bit timer/counter with various operating modes
• Analog to digital converter with 12 input channels and 10-bit resolution
• One synchronous SIO module
• One IIC module
• Two 12-bit PWM output

The KS86C4208 microcontroller is ideal for use in a wide range of electronic applications requiring simple timer/counter, PWM, ADC, SIO, IIC, ZCD and capture functions. KS86C4208 is available in a 28/32-pin SOP and a 30-pin SDIP package.
