PRODUCT OVERVIEW
SAM8 PRODUCT FAMILY
Samsungs SAM87 family 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 of six CPU clocks) can be assigned to specific interrupt levels.

S3C8075/P8075 MICROCONTROLLERS
S3C8075/P8075 single-chip 8-bit microcontrollers are based on the powerful SAM87 CPU architecture. The internal register file is logically expanded to increase the on-chip register space. The S3C8075 has 16-Kbyte mask-programmable ROM. The S3P8075 has 16-Kbyte one-time-programmable EPROM.

Following Samsungs modular design approach, the following peripherals are integrated with the SAM87 core:

— Seven programmable I/O ports (total 56 pins)
— One 8-bit basic timer for oscillation stabilization and watchdog functions
— One synchronous operating mode and three full-duplex asynchronous UART modes
— Two 8-bit timers with interval timer and PWM modes
— Two 16-bit general-purpose timer/counters
