1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
SAM87RC PRODUCT FAMILY
Samsung's new SAM87RC 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.
Timer/counters with selectable operating modes are included to support real-time operations. Many SAM87RC
microcontrollers have an external interface that provides access to external memory and other peripheral devices.
A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more
interrupt sources and vectors. Fast interrupt processing (within a minimum six CPU clocks) can be assigned to
one interrupt level at a time.
KS88C4708/C4716 MICROCONTROLLER
The KS88C4708/C4716 single-chip 8-bit microcontroller is designed for useful 10-bit resolution A/D converter,
UART, PWM application field. Its powerful SAM87RC CPU architecture includes. The internal register file is
logically expanded to increase the on-chip register space.
The KS88C4708/C4716 has 8/16 K bytes of on-chip program ROM. Following Samsung's modular design
approach, the following peripherals are integrated with the SAM87RC core:
— Large number of programmable I/O ports (42 SDIP: 34 pins, 44 QFP: 36 pins)
— One asynchronous UART module
— Analog-to-digital converter with eight input channels and 10-bit resolution
— One 8-bit basic timer for watchdog function
— One 8-bit timer/counter with three operating modes (Timer 0)
— One general-purpose 16-bit timer/counters with three operating modes (Timer 1)
The KS88C4708/C4716 is a versatile general-purpose microcontroller that is ideal for use in a wide range of
electronics applications requiring complex timer/counter, PWM, capture, and UART.
It is available in a 42-pin SDIP or 44-pin QFP package.
OTP
The KS88P4716 is an OTP (One Time Programmable) version of the KS88C4708/C4716 microcontroller. The
KS88P4716 microcontroller has an on-chip 16-Kbyte one-time-programmable EPROM instead of a masked
ROM. The KS88P4716 is comparable to the KS88C4708/C4716, both in function in D.C. electrical characteristics
and in pin configuration.
