1 PRODUCT OVERVIEW

SAM87RI PRODUCT FAMILY

Samsung’s SAM87Ri 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 address/data bus architecture and a large number of bit-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.

KS86C4204/C4208/P4208 MICROCONTROLLER

The KS86C4204/C4208/P4208 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It
is built around the powerful SAM87Ri CPU core. The KS86C4204/C4208/P4208 is 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
space, the size of the internal register file was logically expanded. The KS86C4204/C4208/P4208 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 KS86C4204/C4208/P4208microcontroller is ideal for use in a wide range of electronic applications requiring
simple timer/counter, PWM, ADC, SIO, IIC, ZCD and capture functions. KS86C4204/C4208/P4208 is available in
a 28/32-pin SOP and a 30-pin SDIP package.

OTP

The KS86P4208 is an OTP (One Time Programmable) version of the KS86C4204/C4208 microcontroller. The
KS86P4208 has on-chip 8-Kbyte one-time-programmable EPROM instead of masked ROM. The KS86P4208 is
fully compatible with the KS86C4204/C4208, in function, in D.C. electrical characteristics and in pin configuration.
