KS88C0916/P0916 MICROCONTROLLER PRODUCT OVERVIEW 1 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. Important CPU features include: — 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 six CPU clocks) can be assigned to specific interrupt levels. KS88C0916/P0916 MICROCONTROLLER The KS88C0916/P0916 single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process and is based on Samsung’s newest CPU architecture. The KS88C0916 is the microcontroller which has 16Kbytes mask-programmable ROM. The KS88P0916 is the microcontroller which has 16Kbytes one-time-programmable EPROM. Using a proven modular design approach, Samsung engineers developed the KS88C0916/P0916 by integrating the following peripheral modules with the powerful SAM87 core: — Four programmable I/O ports, including three 8-bit ports and one 2-bit port, for a total of 26 pins. — Twelve bit-programmable pins for external interrupts. — One 8-bit basic timer for oscillation stabilization and watchdog functions (system reset). Figure 1-1. KS88C0916 Microcontroller — One 8-bit timer/counter and one 16-bit timer/counter with selectable operating modes. — One 8-bit counter with auto-reload function and one-shot or repeat control. The KS88C0916 is a versatile general-purpose microcontroller. It is currently available in a 32-pin SOP and SDIP package. 1-1 PRODUCT OVERVIEW KS88C0916/P0916 MICROCONTROLLER FEATURES CPU • SAM87 CPU core Timers and Timer/Counters • One programmable 8-bit basic timer (BT) for oscillation stabilization control or watchdog timer (software reset) function One 8-bit timer/counter (Timer 0) with three operating modes; Interval, Capture and PWM One 16-bit timer/counter (Timer 1) with two operating modes; Interval and Capture Memory • • 16-Kbyte internal program memory (ROM) 317-byte internal register file • • Instruction Set • • 78 instructions IDLE and STOP instructions added for powerdown modes Carrier Frequency Generator • One 8-bit counter with auto-reload function and one-shot or repeat control (Counter A) Instruction Execution Time • 750 ns at 8-MHz fOSC (minimum) • Operating Temperature Range – 20°C to + 85°C Interrupts • • • Six interrupt levels and 18 interrupt sources 15 vectors (14 sources have a dedicated vector address and four sources share a single vector) Fast interrupt processing feature (for one selected interrupt level) Operating Voltage Range • • 2.0 V to 5.5 V at 4 MHz fOSC 2.4 V to 5.5 V at 8 MHz fOSC Package Type I/O Ports • • Three 8-bit I/O ports (P0–P2) and one 2-bit port (P3) for a total of 26 bit-programmable pins Twelve input pins for external interrupts • • 32-pin SOP 32-pin SDIP 1-2 KS88C0916/P0916 MICROCONTROLLER PRODUCT OVERVIEW BLOCK DIAGRAM P0.0
