PRODUCT OVERVIEW
KS88-SERIES MICROCONTROLLERS
Samsung's KS88 series 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. Important CPU features include:
— Efficient register-oriented architecture
— Selectable CPU clock sources
— Idle and Stop power-down mode release by interrupt
— Built-in basic timer with watchdog function
A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more
interrupt sources and vectors. Fast interrupt processing (within a minimum six CPU clocks) can be assigned to
specific interrupt levels.
KS88C01416/C01424 MICROCONTROLLER
The KS88C01416/C01424 single-chip CMOS
microcontroller is fabricated using a highly advanced
CMOS process, based on Samsung’s newest CPU
architecture.
The KS88C01416/C01424 is the microcontroller
which has 16/24-Kbyte mask-programmable ROM.
The KS88P01416/P01424 is the microcontroller
which has 16/24-Kbyte one-time-programmable
EPROM.
Using a proven modular design approach, Samsung
engineers developed the KS88C01416/C01424 by
integrating the following peripheral modules with the
powerful SAM87 core:
— Four programmable I/O ports, including three
8-bit ports and one 2-bit port, for a total of 26
pins.
— Internal LVD circuit and twelve bit-
programmable pins for external interrupts.
— One 8-bit basic timer for oscillation stabilization
and watchdog functions (system reset).
— One 8-bit timer/counter and one 16-bit
timer/counter with selectable operating modes.
— One 8-bit counter with auto-reload function and
one-shot or repeat control.
The KS88C01416/C01424 is a versatile general-
purpose microcontroller which is especially suitable
for use as unified remote transmitter controller. It is
currently available in a 32-pin SOP and SDIP
package for KS88C01416 and KS88C01424. And
available in 40 DIP package only for KS88C01424.
OTP
The KS88P01416/P01424 is an OTP (One Time Programmable) version of the KS88C01416/C01424
microcontroller. The KS88P01416/P01424 microcontroller has an on-chip 16/24-Kbyte one-time-programmable
EPROM instead of a masked ROM. The KS88P01416/P01424 is comparable to the KS88C01416/C01424, both
in function and in pin configuration.

Description
I/O port with bit-programmable pins.
Configurable to input or push-pull output
mode. Pull-up resistors are assignable by
software. Pins can be assigned individually
as external interrupt inputs with noise filters,
interrupt enable/disable, and interrupt
pending control.
I/O port with bit-programmable pins.
Configurable to C-MOS input mode or
output mode. Pin circuits are either push-
pull or n-channel open-drain type. Pull-up
resistors are assignable by software.
General-purpose I/O port with bit-
programmable pins. Configurable to C-MOS
input mode, push-pull output mode, or n-
channel open-drain output mode. Pull-up
resistors are assignable by software. Lower
nibble pins, P2.3–P2.0, can be assigned as
external interrupt inputs with noise filters,
interrupt enable/disable, and interrupt
pending control.
2-bit I/O port with bit-programmable pins.
Configurable to C-MOS input mode, push-
pull output mode, or n-channel open-drain
output mode. Pull-up resistors are
assignable by software. The two port 3 pins
have high current drive capability.
System clock input and output pins
System reset signal input pin and back-up
mode input pin. The pin circuit is a C-MOS
input.
