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.

OVERVIEW
KS88P4716 OTP
The KS88P4716 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the KS88C4708/C4716 microcontroller. It has an on-chip OTP ROM instead of a masked ROM. The EPROM is accessed by serial data format. The KS88P4716 is fully compatible with the KS88C4708/C4716, both in function in D.C. electrical characteristics and in pin configuration. Because of its simple programming requirements, the KS88P4716 is ideal as an evaluation chip for the KS88C4708/C4716.

Table 16-1. Descriptions of Pins Used to Read/Write the EPROM Main Chip Pin Name P4.3 Pin Name SDAT Pin No. 9(3) During Programming I/O I/O Function Serial data pin. Output port when reading and input port when writing. Can be assigned as a Input/push-pull output port. Serial clock pin. Input only pin. Power supply pin for EPROM cell writing (indicates that OTP enters into the writing mode). When 12.5 V is applied, OTP is in writing mode and when 5 V is aplied, OTP is in reading mode. (Option) Chip Initialization Logic power supply pin. VDD should be tied to +5 V during programming.

OPERATING MODE CHARACTERISTICS When 12.5 V is supplied to the VPP (TEST) pin of the KS88P4716, the EPROM programming mode is entered. The operating mode (read, write, or read protection) is selected according to the input signals to the pins listed in Table 16-3 below. Table 16-3.
