KS57C4104/P4104/C4204/P4204/C4304/P4304	PRODUCT OVERVIEW

1 PRODUCT OVERVIEW

OVERVIEW

The KS57C4104/KS57C4204/KS57C4304 single-chip CMOS microcontroller has been designed for very high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontroller).

With an A/D converter, LED direct drive pins, an 8-bit serial I/O interface, and an 8-bit timer/counter, the KS57C4104/KS57C4204/KS57C4304 offers you an excellent design solution for a wide variety of home appliance applications — electric fans, cookers, boilers, and air conditioners, for example.

Up to 35 pins of the 42-pin SDIP or 44-pin QFP package can be dedicated to I/O. Seven vectored interrupts provide fast response to internal and external events.

In addition, the KS57C4104/KS57C4204/KS57C4304's advanced CMOS technology provides for low power consumption and a wide operating voltage range.

OTP

The KS57C4104/KS57C4204/KS57C4304 microcontroller is also available in OTP (One Time Programmable) version, KS57P4104/KS57P4204/KS57P4304. KS57P4104/KS57P4204/KS57P4304 microcontroller has an onchip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The KS57P4104/KS57P4204/KS57P4304 is comparable to KS57C4104/KS57C4204/KS57C4304, in function, in D.C. electrical characteristics and in pin configuration.

DEVELOPMENT SUPPORT

The Samsung Microcontroller Development System, SMDS, provides you with a complete PC-based development environment for KS57-series microcontrollers that is powerful, reliable, and portable. In addition to its window-based program development structure, the SMDS toolset includes versatile debugging, trace, instruction timing, and performance measurement applications.

The Samsung Generalized Assembler (SAMA) has been designed specifically for the SMDS environment and accepts assembly language sources in a variety of microprocessor formats. SAMA generates industry-standard hex files that also contain program control data for SMDS compatibility.

Table 14-10. A/D Converter Electrical Characteristics

(TA = – 10 °C to + 70 °C, VDD = 3.5 V to 5.5 V, VSS = AVSS = 0 V)

Parameter	Symbol	Condition	Min	Typ	Max	Units
Resolution	–	–	8	8	8	bit
Absolute accuracy (1)	–	2.5 V < AVREF < VDD	–	–	± 1.5	LSB
Conversion time (2)	tCON	–	–	96/fx (3)	–	µs

Analog input impedance	RAN	–	–	1000	–	MΩ

NOTES:

1.Absolute accuracy does not include the quantization error (± 1/2 LSB).

2.Conversion time is the time required from the moment a conversion operation starts until it ends (EOC = 0).

3.fx' is the abbreviation for system clock.

NOTES:

1.During oscillation stabilization time, CPU operation must be stopped to avoid unstable operation upon oscillation start.

2.The basic timer causes a delay of 217/fx after a reset.
