PRODUCT OVERVIEW
1 PRODUCT OVERVIEW
SAM88RCRI PRODUCT FAMILY
Samsung's SAM88RCRI family of 8-bit single-chip CMOS microcontrollers offer 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.
S3C9454B/F9454B MICROCONTROLLER
The S3C9454B/F9454B single-chip 8-bit microcontroller is designed for useful A/D converter application field. The
S3C9454B/F9454B uses powerful SAM88RCRI CPU and S3C9454B/F9454B architecture. The internal register
file is logically expanded to increase the on-chip register space.
The S3C9454B/F9454B has 4K bytes of on-chip program ROM and 208 bytes of RAM. The S3C9454B/F9454B is
a versatile general-purpose microcontroller that is ideal for use in a wide range of electronics applications requiring
simple timer/counter, PWM. In addition, the S3C9454B/F9454’s advanced CMOS technology provides for low
power consumption and wide operating voltage range.
Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core:
— Three configurable I/O ports (18 pins)
— Four interrupt sources with one vector and one interrupt level
— One 8-bit timer/counter with time interval mode
— Analog to digital converter with nine input channels(MAX) and 10-bit resolution
— One 8-bit PWM output
The S3C9454B/F9454B microcontroller is ideal for use in a wide range of electronic applications requiring simple
timer/counter, PWM, ADC. S3C9454B/F9454B is available in a 20/16-pin DIP and a 20/16-pin SOP and a 20/16-
pin SSOP package.
MTP
The S3F9454B is an MTP (Multi Time Programmable) version of the S3C9454B microcontroller. The S3F9454B
has on-chip 4-Kbyte multi-time programmable flash ROM instead of masked ROM. The S3F9454B is fully
compatible with the S3C9454B, in function, in D.C. electrical characteristics and in pin configuration.
