PRODUCT OVERVIEW
PRODUCT OVERVIEW
SAM88RCRI PRODUCT FAMILY
Samsung's SAM88RCRI 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.
A dual address/data bus architecture and a large number of 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. Many SAM88RCRI microcontrollers have an external interface that provides access to external memory and other peripheral
devices.
S3C9688/P9688 MICROCONTROLLER
The S3C9688/P9688 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 S3C9688 has 8 K bytes of program memory on-chip.
Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core:
— Five configurable I/O ports (32 pins)
— 20 bit-programmable pins for external interrupts
— 8-bit timer/counter with three operating modes
— Low speed USB function
The S3C9688/P9688 is a versatile microcontroller that can be used in a wide range of low speed USB support general purpose applications. It
is especially suitable for use as a keyboard controller and is available in a 42-pin SDIP and a 44-pin QFP package.
OTP
The S3C9688/P9688 microcontroller is also available in OTP (One Time Programmable) version, S3P9688. S3P9688 microcontroller has an
on-chip 8-Kbyte one-time-programmable EPROM instead of masked ROM. The S3P9688 is comparable to S3C9688/P9688, both in function
and in pin configuration.
