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.

It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data format. The S3P9428 is fully compatible with the S3C9424/C9428, both in function and in pin configuration. Because of its simple programming requirements, the S3P9428 is ideal for use as an evaluation chip for the S3C9424/C9428.
