KS88C4504/P4504 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM87 RC 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. The 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 specific interrupt levels. KS88C4504 MICROCONTROLLER The KS88C4504 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is based on the powerful SAM87RC CPU core. Stop and Idle power-down modes were implemented to reduce power consumption. The size of the internal register file is logically expanded, increasing the addressable on-chip register space to 1040 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of program and data memory. The KS88C4504 is a versatile microcontroller that is ideal for use in a wide range of general-purpose applications such as CD-ROM/DVD-ROM drives. Using the SAM87RC modular design approach, the following peripherals were integrated with the SAM87RC CPU core: — Five configurable 8-bit general I/O ports — One 2-bit general I/O ports — Full-duplex serial data port with one synchronous operating modes — Two 8-bit timers with interval timer — Two 16-bit timers/counters with PWM operating modes or capture modes — One voltage level detector pin — Four embedded chip selection pins (CS0–CS4) or normal I/O ports — Two programmable 8-bit PWM modules with corresponding output pins — A/D converter with 4 selectable input pins OTP The KS88C4504 microcontroller is also avaiable in OTP(One Time Programmable) version, KS88P4504 The KS88P4504 microcontroller has an on-chip 4K-byte one-time-programable EPROM instead of masked ROM. The KS88P4504 is comparable To KS88C4504, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW KS88C4504/P4504 FEATURES CPU • SAM87RC CPU core General I/O Ports • • Memory • • 1040-byte internal register file 4-Kbyte internal program memory Interrupts • External Interface • • • 64K-byte external data memory 64K-byte external program memory area (ROMless) 60K-byte external program memory and 4K-byte internal program memory • • Six edge-driven external interrupts Two level-driven external interrupts Fast interrupt mode processing • Five 8-bit general I/O ports (port 0, 1, 2, 3, 4) One 2-bit general I/O port (port 5) Port 2 can drive LED directly PWM • • • Four output channels (PWM0, PWM1, TCPWM, TDPWM) 8-bit resolution with a 4-bit prescaler (PWM0, PWM1) From 16-bit counter (Timer C/D) (TCPWM, TDPWM) ADC • • SIO • • • • 8-bit transmit/receive mode 8-bit receive mode LSB-first or MSB-first transmission selectable Internal or external clock mode Can be used as a general input/output port 8-bit resolution four channels Embedded chip selection • To reduce interface glue logic, chip selection logic is bold Voltage level detector • To prevent MCU from malfunctioning in an unstable power level, a voltage level detector circuit is inserted 8-bit Timers • Two 8-bit timers with interval timer mode (Timer A and B) Operating Voltage Range • 2.7 V to 5.5 volts (@12 MHz) 16-bit Timer/Counters • • • • Two programmable 16-bit timer/counters Interval, or event counter mode operation 16-bit capture and 16-bit PWM mode Internal or external clock source Operating Temperature Range • – 40 °C to + 85 °C Package Types • 80-pin QFP or TQFP Basic Timer (Watchdog Timer) • • Overflow signal makes a system reset 8-bit timer with interval timer mode Operating frequency • 25 MHz (4.5 V to 5.5 V) 1-2 KS88C4504/P4504 PRODUCT OVERVIEW BLOCK DIAGRAM EXTERNAL ADDRESS/DATA A8–A15 A0–A7 D0–D7 External Interface Block RESET EA SAM8 BUS P5.1 P5.0( WAIT ) Port 5 Port I/O & Interrupt Control Watchdog time r Port 0 P0.0–P0.3 P0.4–P0.7/ ADC0–ADC3 P4.0–P4.7/ CS0–CS4 Port 4/ Chip selection Logic Port 1 P1.0–P1.4 P1.5–P1.7/ SI, SO, SCK Timers A and B SAM87 RC CPU Port 2 P2.0–P2.7/ INT0–INT7 TCCK TDCK TCOUT TDOUT SO SI SCK Timers C and D P3.0–P3.7/ TDCK, TCCK TDCAP, TCCAP TCOUT, TDOUT PWM0, PWM1 Serial Port 1040-Byte Register File Port 3 SAM8 BUS AV SS (Internal) AV REF VDD1,V SS1 VDD2 ,V SS2 PWM Module A/D Converter 4-Kbyte ROM ADC0 /P0.4 – ADC3 /P0.7 PWM0 PWM1 Figure 1-1.
