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.
S3C9424/C9428/P9428 MICROCONTROLLER
The S3C9424/C9428/P9428 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is
built around the powerful SAM87Ri CPU core. The S3C9424/C9428/P9428 is a versatile microcontroller, with its
A/D converter, SIO, IIC and a zero-crossing detection capability 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 S3C9424/C9428/P9428 have 4K-byte or
8K-byte of program memory on-chip (ROM) and 208-bytes of general purpose register area RAM.
Using the SAM87Ri design approach, the following peripherals were integrated with the SAM87Ri core:
• Four configurable I/O ports (24 pins)
• Nine interrupt sources with one vector and one interrupt level
• Two 8-bit timer/counter with various operating modes
• Analog to digital converter with 12 input channels and 10-bit resolution
• One synchronous SIO module
• One IIC module
• Two 12-bit PWM output
The S3C9424/C9428/P9428 microcontroller is ideal for use in a wide range of electronic applications requiring
simple timer/counter, PWM, ADC, SIO, IIC, ZCD and capture functions. S3C9424/C9428/P9428 is available in a
28/32-pin SOP and a 30-pin SDIP package.
OTP
The S3P9428 is an OTP (One Time Programmable) version of the S3C9424/C9428 microcontroller. The
S3P9428 has on-chip 8-K-byte one-time-programmable EPROM instead of masked ROM. The S3P9428 is fully
compatible with the S3C9424/C9428, in function, in D.C. electrical characteristics and in pin configuration.
