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 dual address/data bus architecture and a large number of bit- or nibble-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. Many SAM87RI microcontrollers have
an external interface that provides access to external memory and other peripheral devices.
KS86C0004/P0004/C0104/P0104 MICROCONTROLLER
The KS86C0004/P0004/C0104/P0104 single-chip 8-bit microcontroller is fabricated using an advanced CMOS
process. It is built around the powerful SAM87RI CPU core.
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 KS86C0004/P0004/C0104/P0104 has 4 K
bytes of program memory on-chip.
Using the SAM87RI design approach, the following peripherals were integrated with the SAM87RI core:
— Five configurable I/O ports (32 pins)
— 12 bit-programmable pins for external interrupts
— 8-bit timer/counter with three operating modes
The KS86C0004/P0004/C0104/P0104 is a versatile microcontroller that can be used in a wide range of general
purpose applications. It is especially suitable for use as a keyboard controller and is available in a 40-pin DIP and
a 44-pin QFP package.
OTP
The KS86C0004/C0104 microcontroller is also available in OTP (One Time Programmable) version,
KS86P0004/P0104. KS86P0004/P0104 microcontroller has an on-chip 8-Kbyte one-time-programmable EPROM
instead of masked ROM. The KS86P0004/P0104 is comparable to KS86C0004/C0104, both in function and in pin
configuration.

14 KS86P0004/P0104 OTP
OVERVIEW
The KS86P0004/P0104 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the
KS86C0004/C0104 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is
accessed by serial data format.
The KS86P0004/P0104 is fully compatible with the KS86C0004/C0104, both in function and in pin configuration.
Because of its simple programming requirements, the KS86P0004/P0104 is ideal for use as an evaluation chip
for the KS86C0004/C0104.

OPERATING MODE CHARACTERISTICS
When 12.5 V is supplied to the VPP (EA) pin of the KS86P0004/P0104, the EPROM programming mode is
entered. The operating mode (read, write, or read protection) is selected according to the input signals to the pins
listed in Table 14-3 below.
