PRODUCT OVERVIEW
SAM87RI PRODUCT FAMILY
Samsung's SAM87RI family 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.
S3C9614/P9614 MICROCONTROLLER
The S3C9614/P9614 microcontroller with USB function can be used in a wide range of general purpose
applications. It is especially suitable for mouse or joystick controller and is available in 20-pin DIP and 24-pin
SOP package.
The S3C9614/P9614 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 S3C9614/P9614 has 4K-bytes of program
memory on-chip and 208 bytes of RAM including 16 bytes of working register.
Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core:
— Two configurable I/O ports (11 pins)
— 7 bit-programmable pins for external interrupts
— 8-bit timer/counter with two operating modes
OTP
The S3C9614 microcontroller is also available in OTP (One Time Programmable) version, S3P9614. S3P9614
microcontroller has an on-chip 4K-byte one-time-programmable EPROM instead of masked ROM. The S3P9614
is comparable to S3C9614, both in function and in pin configuration.
