PRODUCT OVERVIEW
SAM88RCRI PRODUCT FAMILY
Samsung's SAM88RCRI family of 8-bit single-chip CMOS microcontrollers offer fast and efficient CPU, a wide
range of integrated peripherals, and supports OTP device.
A dual address/data bus architecture and bit- or nibble-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.
S3C921F/P921F MICROCONTROLLER
The S3C921F can be used for dedicated control functions in a variety of applications, and is especially designed
for application with voice synthesizer or etc.
The S3C921F/P921F single-chip 8-bit microcontroller is fabricated using an advanced CMOS process. It is built
around the powerful SAM88RCRI CPU core.
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 S3C921F/P921F has 64 Kbytes of
program ROM and 192 Kbytes of data ROM on-chip (S3C921F), and 720 bytes of RAM including 16 bytes of
working register and 128 bytes of LCD display RAM.
Using the SAM88RCRI design approach, the following peripherals were integrated with the SAM88RCRI core:
— Four configurable I/O ports including ports shared with segment/common drive outputs
— 8-bit programmable pins for external interrupts
— One 8-bit basic timer for oscillation stabilization and watch-dog functions
— One 8-bit and one 16-bit timer/counter with selectable operating modes
— Watch timer for real time
— Two PWM modules for direct speaker drive
OTP
The S3C921F microcontroller is also available in OTP (One Time Programmable) version. S3P921F
microcontroller has an on-chip 256 Kbyte one-time-programmable EPROM instead of masked ROM. The
S3P921F is comparable to S3C921F, both in function and in pin configuration.
