(3 for Timers, 6 for UART, 8 for External interrupts, 4 for DMA, 2 for RTC, 2 for IIC, 2 for RCSR (Remote Control Signal Receiver), and 7 for PCI)) • Software polling Interrupt mode • Selectable level- or edge-triggered external interrupts source • Programmable IRQ/FIQ for each interrupt request • Supports FIQ (Fast Interrupt Request) for very urgent interrupt request Timer • 3-ch 16-bit Timer with DMA-based or interrupt- based operation Watchdog Timer • 16-bit Watchdog Timer RCSR (Remote Control Signal Receiver) • 8-step FIFO • FIFO interrupt is generated on full (8) step overflow RTC (Real Time Clock) • Full clock feature: sec, min, hour, date, day, week, month, and year • 32.768 kHz input clock • Alarm interrupt • Time tick interrupt GPIO (General-Purpose Input/Output) Ports • 8 external interrupt ports • 44 multiplexed input/output ports. S3C2800 MICROCONTROLLER UART • 2-channel UART with DMA-based or interrupt based operation • Supports 5-bit, 6-bit, 7-bit, or 8-bit serial data transmit/receive • Supports hardware handshaking during transmit/receive operation • Programmable baud rates (up to 230.4Kbps). • Supports IrDA 1.0 (up to 115.2Kbps) • Loop back mode for testing • Program accessible 16-byte FIFO (2x16 byte FIFO for transmit/receive data) DMA Controller • 4-channel general-purpose Direct Memory Access controller without CPU intervention. • Support memory to memory, memory to I/O and I/O to I/O DMA operations of the following 6 types: Software, 3 internal function blocks (UART0, UART1, Timer), and 2 External requests • Burst transfer mode to enhance the transfer rate on the FPDRAM, EDODRAM and SDRAM IIC-BUS Interface • 2-ch Multi-Master IIC-Bus with interrupt-based operation • Serial, 8-bit oriented, bi-directional data transfers at up to 100 Kbit/s in the standard mode or up to 400 Kbit/s in the fast mode Operating Voltage Range • Core: 1.8 V -0.1 V/+0.15 V • I/O: 3.3 V ± 0.3 V Operating Frequency • Up to 200 MHz. Package • 208-pin LQFP 3 5 Page PRELIMINARY DATA SHEET S3C2800 MICROCONTROLLER Table 2. 208-Pin LQFP Pin Assignment (Continued) Pin # Pin Name 71 GPE2/nCTS1 72 GPE3/nRTS1 73 VDD 74 VSS 75 GPE4/nXDREQ0 76 GPE5/nXDACK0 77 GPE6/nXDREQ1 78 GPE7/nXDACK1 79 GPF0/EXTINT0 80 GPF1/EXTINT1 81 GPF2/EXTINT2 82 GPF3/EXTINT3 83 GPF4/EXTINT4 84 GPF5/EXTINT5 85 GPF6/EXTINT6 86 GPF7/EXTINT7 87 VDD3OP 88 VSS3OP 89 XTAL0 90 EXTAL0 91 TEST 92 nRESET 93 XTAL1 94 EXTAL1 95 OM0 96 OM1 97 AVDD 98 PLLCAP 99 AVSS 100 PCI_nRST 101 PCI_CLK 102 PCI_nGNT1 103 PCI_nGNTx2 104 PCI_nGNTx3 105 PCI_nREQ1 Default Function GPE2 GPE3 VDD VSS GPE4 GPE5 GPE6 GPE7 GPF0 GPF1 GPF2 GPF3 GPF4 GPF5 GPF6 GPF7 VDD3OP VSS3OP XTAL0 EXTAL0 TEST nRESET XTAL1 EXTAL1 OM0 OM1 AVDD PLLCAP AVSS PCI_nRST PCI_CLK PCI_nGNT1 PCI_nGNTx2 PCI_nGNTx3 PCI_nREQ1 I/O State @Initial IO IO P P IO IO IO IO IO IO IO IO IO IO IO IO P P AI(3) AO(3) I I I O I(1) I(1) P AO(3) P I I IO O O IO I/O TYPE phbsu50ct8sm vdd1ih vss3i phbsu50ct8sm vdd3op vss3op phsoscm16 phis phisu phsosck17 phis vdd1t_abb poar50_abb vss1t_abb/vbb1_abb ptipci ptbpci ptopci ptbpci 9 11 Page
