PRODUCT OVERVIEW

KS88-SERIES MICROCONTROLLES

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. Among the 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

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 of six CPU clocks) can be assigned to

specific interrupt levels.

KS88C2148/P2148 MICROCONTROLLER

The KS88C2148/P2148 single-chip CMOS

microcontroller is fabricated using the highly

advanced CMOS process, based on Samsung’s

newest CPU architecture.

The KS88C2148 is a microcontroller with a 48-Kbyte

mask-programmable ROM embedded.

The KS88P2148 is a microcontroller with a 48-Kbyte

one-time-programmable ROM embedded.

Using a proven modular design approach, Samsung

engineers have successfully developed the

KS88C2148/P2148 by integrating the following

peripheral modules with the powerful SAM8 core:

— Six programmable I/O ports, including five 8-bit

ports and one 7-bit port, for a total of 47 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.

— Watch timer for real time.

— 4-input A/D converter

— Serial I/O interface

The KS88C2148/P2148 is versatile microcontroller

for cordless phone, pager, etc. They are currently

available in 80-pin TQFP and 80-pin QFP package.

OTP

The KS88P2148 is an OTP (One Time Programmable) version of the KS88C2148 microcontroller. The

KS88P2148 microcontroller has an on-chip 48-Kbyte one-time-programmable EPROM instead of a masked ROM.

The KS88P2148 is comparable to the KS88C2148, both in function and in pin configuration.
