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. 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 four CPU clocks) can be assigned to
specific interrupt levels.
KS88C2416/P2416/C2432/P2432 MICROCONTROLLER
The KS88C2416/P2416/C2432/P2432 single-chip
CMOS microcontroller are fabricated using the highly
advanced CMOS process, based on Samsung's
newest CPU architecture.
The KS88C2416 is a microcontroller with a 16-Kbyte
mask-programmable ROM embedded.
The KS88C2432 is a microcontroller with a 32-Kbyte
mask-programmable ROM embedded.
The KS88P2416 is a microcontroller with a 16-Kbyte
one-time-programmable ROM embedded.
The KS88P2432 is a microcontroller with a 32-Kbyte
one-time-programmable ROM embedded.
Using a proven modular design approach, Samsung
engineers have successfully developed the
KS88 C2416/P2416/C2432/P2432 by integrating the
following peripheral modules with the powerful SAM8
core:
-- Six programmable I/O ports, including five 8-bit
ports and one 5-bit port, for a total of 45 pins.
-- Eight bit-programmable pins for external
interrupts.
-- One 8-bit basic timer for oscillation stabilization
and watchdog functions (system reset).
-- Two 8-bit timer/counter and two 16-bit
timer/counter with selectable operating modes.
-- Watch timer for real time.
-- 8-input A/D converter
-- Serial I/O interface
The KS88C2416/P2416/C2432/P2432 is versatile
microcontroller for camera, LCD and ADC
application, etc. They are currently available in 80-pin
TQFP and 80-pin QFP package
OTP
The KS88P2416/P2432 are OTP (One Time Programmable) version of the KS88C2416/C2432 microcontroller.
The KS88P2416 microcontroller has an on-chip 16-Kbyte one-time-programmable EPROM instead of a masked
ROM. The KS88P2432 microcontroller has an on-chip 32-Kbyte one-time-programmable EPROM instead of a
masked ROM. The KS88P2416 is comparable to the KS88C2416, both in function and in pin configuration.
The KS88P2432 is comparable to the KS88C2432, both in function and in pin configuration.
