1 PRODUCT OVERVIEW
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.
S3C9004/P9004/C9014/P9014 MICROCONTROLLER
The S3C9004/P9004/C9014/P9014 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 S3C9004/P9004/C9014/P9014 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 S3C9004/P9004/C9014/P9014 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 S3C9004/C9014 microcontroller is also available in OTP (One Time Programmable) version,
S3P9004/P9014. S3P9004/P9014 microcontroller has an on-chip 8-Kbyte one-time-programmable EPROM
instead of masked ROM. The S3P9004/P9014 is comparable to S3C9004/C9014, both in function and in pin
configuration.

Description
Bit-programmable I/O port for Schmitt trigger
input or open-drain output. Port0 can also be
configured as external interface address lines A8-
A12.
Bit-programmable I/O port for Schmitt trigger
input, push-pull, or open-drain output. Port1 can
alternatively be used as external interface
address/data lines AD0-AD7.
Bit-programmable I/O port for Schmitt trigger
input or push-pull output. Port2 can be
individually configured as external interrupt
inputs. Especially, P2.0-2.3 can be configured for
external bus control signal.
Same general characteristics as Port1. Port3 are
designed for to drive LED directly. P3.3 can be
used to system clock output (CLO) port.
Bit-programmable I/O port. Input mode or n-
channel open-drain output mode is software
assignable. Port4 can be individually configured
as external interrupt inputs. Pull-up resistors are
also software assignable. Especially, P4.1 can be
used T0CLK input and P4.3 also T0OUT for
Timer 0.
System clock input and output pin (for RC
oscillator, crystal/ceramic oscillator, or external
clock source)
External interrupt for bit-programmable port2 and
port4 pins when set to input mode.
RESET signal input pin. Schmitt trigger input with
internal pull-up resistor.
External Memory Access (EA) pin with 2 modes:
0V = Normal Operation Mode
5V = ROMLESS Operation Mode
(Must be connected to VSS during normal
operation mode)
Power input pin
Vss1 is a ground power for CPU core.
Vss2 is a ground power for I/O and OSC block
No connection
(This pin would be better connecting to VSS)
