PRODUCT OVERVIEW
KS88-SERIES MICROCONTROLLERS
Samsung's KS88 series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU with a wide
range of integrated peripheral, in various mask-programmable ROM sizes. Among its major CPU features are:
-- Efficient register-oriented architecture
-- Selectable CPU clock sources
-- Idle and Stop power-down mode release by interrupt
-- Built-in basic timer with watchdog function
The 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 of six CPU clocks) can be assigned to
specific interrupt levels.
KS88C0416/C0424 MICROCONTROLLER
The KS88C0416/C0424 single-chip CMOS microcontrollers are fabricated using a highly advanced CMOS
process, based on Samsung's newest CPU architecture.
The KS88C0416/C0424 are microcontrollers containing a 16/24-Kbyte mask-programmable ROM. The
KS88P0416/P0424 are microcontroller containing a 16/24-Kbyte one-time-programmable EPROM.
Using a proven modular design approach, Samsung engineers have successfully developed the
KS88C0416/C0424 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.
-- 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 KS88C0416/C0424 are versatile general-purpose microcontrollers especially suitable for use as a unified
remote transmitter controller.
OTP
The KS88P0416/P0424 is an OTP (One Time Programmable) version of the KS88C0416/C0424 microcontroller.
The KS88P0416/P0424 microcontroller has an on-chip 16/24-Kbyte one-time-programmable EPROM instead of a
masked ROM. The KS88P0416/P0424 is comparable to the KS88C0416/C0424, both in function and in pin
configuration.
