Among the major CPUfeatures are: Efficient register-oriented architecture Selectable CPU clock sources Idle and Stop power-down mode release by interrupt Built-in basic timer with watchdog functionA sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or moreinterrupt sources and vectors. Fast interrupt processing (within a minimum of four CPU clocks) can beassigned to specific interrupt levels.KS88C2416/P2416/C2432/P2432 MICROCONTROLLERThe KS88C2416/P2416/C2432/P2432 single-chip CMOS microcontroller are fabricated using the highlyadvanced CMOS process, based on Samsungs 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 KS88C2416/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 interfaceThe 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.OTPThe KS88P2416/P2432 are OTP (One Time Programmable) version of the KS88C2416/C2432microcontroller. The KS88P2416 microcontroller has an on-chip 16-Kbyte one-time-programmable EPROMinstead 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 infunction and in pin configuration.MICOM DATA (CD)4PIN ASSIGNMENT7BLOCK
