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.
