S3C9404/P9404/C9414/P9414 PRODUCT OVERVIEW

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.

S3C9404/C9414 MICROCONTROLLER

The S3C9404/C9414 single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built
around the powerful SAM87Ri CPU core. The S3C9404/C9414 is a versatile microcontroller, with its A/D
converter 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 S3C9404/C9414 has 4-Kbytes 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 (S3C9404: 22 pins, S3C9414: 16 pins)

— Six interrupt sources with one vector and one interrupt level
— Two 8-bit timer/counter with various operating modes
— Analog to digital converter (S3C9404: 8-bit, 8-channel, S3C9414: 10-bit, 5-channel)
— One zero cross detection module

The S3C9404/C9414 microcontroller is ideal for use in a wide range of electronic applications requiring simple
timer/counter, PWM, ADC, ZCD and capture functions. S3C9404 is available in a 30-pin SDIP and a 32-pin SOP
package. S3C9414 is available in a 24-pin SDIP and a 24-pin SOP package.

OTP

The S3P9404/P9414 is an OTP (one time programmable) version of the S3C9404/C9414 microcontroller. The
S3P9404/P9414 has on-chip 4-Kbyte one-time programmable EEPROM instead of masked ROM. The
S3P9404/P9414 is fully compatible with the S3C9404/C9414, in function, in D.C. electrical characteristics and in
pin configuration.

S3C9404/P9404/C9414/P9414 S3P9404/P9414 OTP

15 S3P9404/P9414 OTP

OVERVIEW

The S3P9404/P9414 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the

S3C9404/C9414 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed
by serial data format.

The S3P9404/P9414 is fully compatible with the S3C9404/C9414 , both in function and in pin configuration.
Because of its simple programming requirements, the S3P9404/P9414 is ideal for use as an evaluation chip for
the S3C9404/C9414 .
