PRODUCT OVERVIEW
1 PRODUCT OVERVIEW
SAM87RI PRODUCT FAMILY
Samsung's SAM87RI 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 SAM87RI microcontrollers have
an external interface that provides access to external memory and other peripheral devices.
S3C9644/C9648/P9648 Microcontroller
The S3C9644/C9648/P9648 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is
built around the powerful SAM87RI 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 S3C9644 has 4K-bytes of program
memory on-chip and S3C9648 has 8K-bytes.
Using the SAM87RI design approach, the following peripherals were integrated with the SAM87RI 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 S3C9644/C9648/P9648 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 S3C9644/C9648 microcontroller is also available in OTP (One Time Programmable) version, S3P9648.
S3P9648 microcontroller has an on-chip 8K-byte one-time-programmable EPROM instead of masked ROM. The
S3P9648 is comparable to S3C9644/C9648, both in function and in pin configuration.
