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 address/data bus architecture and a large number of bit-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.
S3C9432/C9434 MICROCONTROLLER
The S3C9432/C9434 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built
around the powerful SAM87Ri CPU core. The S3C9432/C9434 is a versatile microcontroller, with its A/D
converter, timer, PWM, and SIO it can be used in a wide range of general purpose applications.
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 S3C9432/C9434 have 2K-bytes or 4Kbytes of program memory on-chip (ROM) and 112-bytes of general purpose register area RAM.
Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core:
— Three configurable I/O ports (13 pins)
— Five interrupt sources with one vector and one interrupt level
— One 8-bit timer/counter with time interval mode
— Analog to digital converter with five input channels and 10-bit resolution
— One synchronous SIO module
— One 12-bit PWM output
The S3C9432/C9434 microcontroller is ideal for use in a wide range of electronic applications requiring simple
timer/counter, PWM, ADC, and SIO. S3C9432/C9434 is available in a 20/18/16-pin DIP and a 20-pin SOP
package.
OTP
The S3P9434 is an OTP (One Time Programmable) version of the S3C9432/C9434 microcontroller. The
S3P9434 has on-chip 4K-byte one-time-programmable EPROM instead of masked ROM. The S3P9434 is fully
compatible with the S3C9432/C9434, in function, in D.C. electrical characteristics and in pin configuration.
