S3C8454/P8454 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. S3C8454 MICROCONTROLLER The S3C8454 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 S3C8454 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 S3C8454 microcontroller is also available in OTP(One Time Programmable) version, S3P8454 The S3P8454 microcontroller has an on-chip 4K-byte one-time-programmable EPROM instead of masked ROM. The S3P8454 is comparable to S3C8454, 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 • • • 64 Kbyte external data memory 64 Kbyte external program memory area (ROMless) 60 Kbyte external program memory and 4 Kbyte 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 S3C8454/P8454 PRODUCT OVERVIEW BLOCK DIAGRAM External Address/Data (A8-A15) (A0-A7) (D0-D7) External Interface Block RESET EA P5.1 P5.0(WAIT ) SAM8 BUS Port 0 Port 5 Port I/O & Interrupt Control Watchdog Timer P0.0-P0.3 P0.4-P0.7/ ADC0-ADC3 P4.0-P4.7/ CS0-CS4 Port4/ 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 1040-Byte Register File P3.0-P3.7/ TDCK, TCCK TDCAP, TCCAP TCOUT, TDOUT PWM0, PWM1 Serial Port Port 3 SAM8 BUS AVSS (Internal) AVREF VDD1, VSS1 VDD2, VSS2 PWM Module A/D Converter 4-Kbyte ROM ADC0/P0.4ADC3/P0.7 PWM0 PWM1 Figure 1-1.

It has an on-chip EPROM instead of masked ROM. The EPROM is accessed by serial data format. S3P8454 is fully compatible with S3C8454, both in function and in pin configuration. As it has simple programming requirements, S3P8454 is ideal for use as an evaluation chip for the S3C8454. 20-1 S3P8454 OTP S3C8454/P8454 A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 PM DM RD WR VLD P5.1 P5.0/WAIT CS3/P4.7 CS2/P4.6 SDAT/CS1/P4.5 SCLK/CS0/P4.4 VDD1/VDD1 VSS1/VSS1 XOUT XIN VPP/EA P4.3 P4.2 RESET/RESET P4.1 P4.0 PWM1/P3.7 PWM0/P3.6 TDOUT/P3.5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 S3P8454 80-QFP (Top View) 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 D7 D6 D5 D4 D3 D2 D1 D0 P0.0 P0.1 P0.2 VDD2 VSS2 P0.3 AVREF P0.4/ADC0 P0.5/ADC1 P0.6/ADC2 P0.7/ADC3 P1.0 P1.1 P1.2 P1.3 P1.4 NOTE: Figure 20-1.
