PRODUCT OVERVIEW
S3C8-SERIES MICROCONTROLLERS
Samsung's S3C8 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. Among the major CPU features are:
— 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 four CPU clocks) can be assigned
to specific interrupt levels.
S3C826A MICROCONTROLLER
The S3C826A single-chip microcontroller are fabricated using the highly advanced CMOS process. Its design is
based on the powerful SAM88RC CPU core. Stop and idle (power-down) modes were implemented to reduce
power consumption.
The S3C826A is a microcontroller with a 48K-byte mask-programmable ROM embedded.
The S3P826A is a microcontroller with a 48K-byte one-time-programmable ROM embedded.
Using the SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC
CPU core:
— Large number of programmable I/O ports (Total 128 pins)
— Synchronous SIO module
— Three 8-bit timer/counters
— One 16-bit timer/counter
— LCD controller/driver
— A/D converter with 4 selectable input pins
OTP
The S3C826A microcontroller is also available in OTP (One Time Programmable) version, S3P826A.
The S3P826A microcontroller has an on-chip 48K-byte one-time-programmable EPROM instead of masked
ROM. The S3P826A is comparable to S3C826A, both in function and in pin configuration.
