s3c9614/p9614 product overview 1- 1 1 product overview sam87ri product family samsung's sam87r i family of 8-bit single-chi p 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 t o 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 so p package. the s3c9614/p9614 single-chip 8-bit microcontroller is fabricated using an advanced cmos process. it is built around the powerful sam87r i 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.
