General Description

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.

S3C825A MICROCONTROLLERERS

The S3C825A 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 S3C825A is a microcontroller with a 48K-byte mask-programmable ROM embedded. The S3P825A 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 67 pins)
- Synchronous SIO module
- Two 8-bit timer/counters
- Two 16-bit timer/counters
- LCD controller/driver
- A/D converter with 4 selectable input pins

OTP

The S3C825A microcontroller is also available in OTP (One Time Programmable) version, S3P825A.
The S3P825A microcontroller has an on-chip 48K-byte one-time-programmable EPROM instead of masked ROM. The S3P825A is comparable to S3C825A, both in function and in pin configuration.
