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-time­programmable 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.
