| KS57C0301/0302 MICROCONTOLLER PRODUCT OVERVIEW 1 PRODUCT OVERVIEW OVER VIEW The KS57C0301/0302 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core. With comparator inputs, high-current LED direct-drive pins, serial I/O interface, and a versatile 8-bit timer/counter, the KS57C0301/0302 offers an excellent design solution for a wide range of applications such as mouse controllers, subsystem controllers, and toys. Up to 15 pins of the 20-pin DIP or 20-pin SOP package can be dedicated to I/O. Pull-up resistors are assignable to all of the pins by software. Four vectored interrupts provide fast response to internal and external events. In addition, the KS57C0301/0302's advanced CMOS technology provides for very low power consumption and a wide operating voltage range. 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 easy to use window-oriented 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 object files that also contain program control data for SMDS compatibility. 1-1 PRODUCT OVERVIEW KS57C0301/0302 MICROCONTROLLER FEATURES Memory -- 1024 x 8-bit program memory (KS57C0301) (ROM) -- 2048 x 8-bit program memory (KS57C0302) (ROM) -- 128 x 4-bit data memory (KS57C0301) (RAM) -- 256 x 4-bit data memory (KS57C0302) (RAM) -- 8-bit receive-only mode -- LSB-first or MSB-first transmission selectable -- Internal or external clock source Interrupts -- One external interrupt vector -- Three internal interrupt vectors -- Two quasi-interrupts Memory-Mapped I/O Structure I/O Pins -- Up to 15 pins for 20-DIP and 20-SOP package Comparator Inputs -- 4-channel mode Internal reference: 4-bit resolution -- 3-channel mode External reference 8-Bit Basic Timer -- Programmable interval timer 8-Bit Timer/Counter -- Programmable interval timer -- External event counter function -- Timer clock output to TIO pin Two Power-Down Modes -- Idle mode: Only the CPU clock stops -- Stop mode: Main system clock stops On-Chip Crystal, Ceramic, Or RC Oscillator -- Crystal/ceramic: 4.19 MHz (typical) -- RC: 1 MHz (typical) -- CPU clock divider circuit (by 4, 8, or 64) Frequency Outputs -- Eight frequency outputs to the CLO pin Instruction Execution Times -- 0.95, 1.91, 15.3 s at 4.19 MHz (5 V), 4 s at 1 MHz (2.7 V) Operating Temperature: Watch Timer -- Time interval generation: 0.5 s, 3.9 ms at 4.19 MHz -- Four frequency outputs to BUZ pin Bit Sequential Carrier -- 16-bit serial data transfer in arbitrary format 8-Bit Serial I/O Interface -- 8-bit transmit/receive mode -- - 40C to 85C Operating Voltage Range: -- 2.7 V to 6.0 V Package Type: -- 20-DIP, 20-SOP 1-2 KS57C0301/0302 MICROCONTROLLER PRODUCT OVERVIEW BLOCK DIAGRAM RESET XIN XOUT P0.0/CLO P0.1/TIO P0.2/INT1 Basic Timer Interrupt Control Block Watch Timer Internal Interrupts P2.0 - P2.3 P3.0/SCK P3.1/SO P3.2/SI P3.3/BUZ I/O Port 2 Instruction Decoder I/O Port 3 Arithmetic and Logic Unit Serial I/O Port Program Status Word Clock Stack Pointer I/O Port 0 Program Counter 8-Bit Timer/ Counter Comparator Flags I/O Port 1 P0.0/KS0/CIN0 P0.1/KS1/CIN1 P0.2/KS2/CIN2 P0.3/KS3/CIN3 Data Memory (2) Program Memory (1) NOTES: 1.
