S3C80A8 - Samsung semiconductor

S3C80A8 S3C8-series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU

Table 1-1. Pin Descriptions Pin Names P0.0–P0.7 Pin Type I/O Pin Description 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. Interrupt .

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. S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 MICROCONTROLLER The S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 single-chip CMOS microcontroller is fabricated using a highly advanced CMOS.
