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.

— 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.

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).

Description

P0.0–P0.7 I/O I/O port with bit-programmable pins.

Configurable to input or push-pull output mode. Pull-up resistors are assignable by software. Pins can be assigned individually as external interrupt inputs with noise filters, interrupt enable/ disable, and interrupt pending control.

P1.0–P1.7 I/O I/O port with bit-programmable pins.

Configurable to Schmitt trigger input mode or output mode. Pin circuits are either pushpull or n-channel open-drain type. Pull-up resistors are assignable by software.

P2.0–P2.3 P2.4–P2.7
