1 PRODUCT OVERVIEW

SAM88RCRI PRODUCT FAMILY

Samsung's SAM88RCRIfamily of 8-bit single-chip CMOS microcontrollers offer fast and efficient CPU, a wide range of integrated peripherals, and supports OTP device.

A dual address/data bus architecture and bit- or nibble-configurable I/O ports provide a flexible programming environment for applications with varied memory and I/O requirements. Timer/counters with selectable operating modes are included to support real-time operations.

S3C9228/P9228 MICROCONTROLLER

The S3C9228 can be used for dedicated control functions in a variety of applications, and is especially designed for application with FRS or etc.

The S3C9228/P9228 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built around the powerful SAM88RCRI CPU core.

Stop and Idle power-down modes were implemented to reduce power consumption. To increase on-chip register space, the size of the internal register file was logically expanded. The S3C9228/P9228 has 8K-byte of program ROM, and 264-byte of RAM (including 16-byte of working register and 20-byte LCD display RAM).

Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core:

—7 configurable I/O ports including ports shared with segment/common drive outputs

—10-bit programmable pins for external interrupts

—One 8-bit basic timer for oscillation stabilization and watch-dog functions

—Two 8-bit timer/counters with selectable operating modes

—Watch timer for real time

—4 channel A/D converter

—8-bit serial I/O interface

OTP

The S3C9228 microcontroller is also available in OTP (One Time Programmable) version. S3P9228 microcontroller has an on-chip 8K-byte one-time-programmable EPROM instead of masked ROM. The S3P9228 is comparable to S3C9228, both in function and in pin configuration.
