1 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.
