IDTTM InterpriseTM Integrated Communications Processor RC32434 Device Overview The RC32434 is a member of the IDT™ Interprise™ family of PCI integrated communications processors. It incorporates a high performance CPU core and a number of on-chip peripherals. The integrated processor is designed to transfer information from I/O modules to main memory with minimal CPU intervention, using a highly sophisticated direct memory access (DMA) engine. All data transfers through the RC32434 are achieved by writing data from an on-chip I/O peripheral to main memory and then out to another I/O module.

Specifically, this device features the 4Kc CPU core developed by MIPS Technologies Inc. (www.mips.com). This core issues a single instruction per cycle, includes a five stage pipeline and is optimized for applications that require integer arithmetic. The CPU core includes 8 KB instruction and 8 KB data caches. Both caches are 4-way set associative and can be locked on a per line basis, which allows the programmer control over this precious on-chip memory resource. The core also features a memory management unit (MMU). The CPU core also incorporates an enhanced joint test access group (EJTAG) interface that is used to interface to in-circuit emulator tools, providing access to internal registers and enabling the part to be controlled externally, simplifying the system debug process. The use of this core allows IDT's customers to leverage the broad range of software and development tools available for the MIPS architecture, including operating systems, compilers, and in-circuit emulators. PCI Interface The PCI interface on the RC32434 is compatible with version 2.2 of the PCI specification. An on-chip arbiter supports up to six external bus masters, supporting both fixed priority and rotating priority arbitration schemes. The part can support both satellite and host PCI configurations, enabling the RC32434 to act as a slave controller for a PCI add-in card application or as the primary PCI controller in the system. The PCI interface can be operated synchronously or asynchronously to the other I/O interfaces on the RC32434 device. Ethernet Interface The RC32434 has one Ethernet Channel supporting 10Mbps and 100Mbps speeds to provide a standard media independent interface (MII or RMII), allowing a wide range of external devices to be connected efficiently. Double Data Rate Memory Controller The RC32434 incorporates a high performance double data rate (DDR) memory controller which supports x16 memory configurations up to 256MB. This module provides all of the signals required to interface to discrete memory devices, including a chip select, differential clocking outputs and data strobes. I/ Controller Memory and I/O Controller The RC32434 uses a dedicated local memory/IO controller including a de-multiplexed 8-bit data and 26-bit address bus. It includes all of the signals required to interface directly to a maximum of four Intel or Motorola-style external peripherals. 2 of 53 January 19, 2006 IDT RC32434 DMA Controller The DMA controller consists of 6 independent DMA channels, all of which operate in exactly the same manner. The DMA controller off-loads the CPU core from moving data among the on-chip interfaces, external peripherals, and memory. The controller supports scatter/gather DMA with no alignment restrictions, making it appropriate for communications and graphics systems. UART Interface The RC32434 contains a serial channel (UART) that is compatible with the industry standard 16550 UART. I2C Interface The standard I2C interface allows the RC32434 to connect to a number of standard external peripherals for a more complete system solution. The RC32434 supports both master and slave operations. General General Purpose I/O Controller The RC32434 has 14 general purpose input/output pins. Each pin may be used as an active high or active low level interrupt or nonmaskable interrupt input, and each signal may be used as a bit input or output port. System Integrity Functions The RC32434 contains a programmable watchdog timer that generates a non-maskable interrupt (NMI) when the counter expires and also contains an address space monitor that reports errors in response to accesses to undecoded address regions.

May 25, 2004: In Table 9, signals MIIRXCLK and MIITXCLK, the Min and Max values for Thigh/Tlow_9c were changed to 140 and 260 respectively and the Min and Max values for Thigh/Tlow_9d were changed to 14.0 and 26.0 respectively. December 8, 2005: In Table 18, corrected error for Capacitance Max value from 8.0 to 10.5. January 19, 2006: Removed all references to NVRAM.

Table 1 Pin Description (Part 6 of 6) EXTBCV I EXTCLK COLDRSTN O I RSTN I/O Pin Characteristics Note: Some input pads of the RC32434 do not contain internal pull-ups or pull-downs. Unused inputs should be tied off to appropriate levels. This is especially critical for unused control signal inputs (such as WAITACKN) which, if left floating, could adversely affect the RC32434’s operation. Also, any input pin left floating can cause a slight increase in power consumption. 9 of 53 January 19, 2006 IDT RC32434 Function Memory and Peripheral Bus Pin Name BDIRN BOEN WEN CSN[3:0] MADDR[21:0] MDATA[7:0] OEN RWN WAITACKN DDRADDR[13:0] DDRBA[1:0] DDRCASN DDRCKE DDRCKN DDRCKP DDRCSN DDRDATA[15:0] DDRDM[1:0] DDRDQS[1:0] DDRRASN DDRVREF DDRWEN PCIAD[31:0] PCICBEN[3:0] PCICLK PCIDEVSELN PCIFRAMEN PCIGNTN[3:0] PCIIRDYN PCILOCKN PCIPAR PCIPERRN PCIREQN[3:0] PCIRSTN PCISERRN PCISTOPN PCITRDYN GPIO[8:0] GPIO[13:9] SCK SDI SDO SCL SDA Type O O O O I/O I/O O O I O O O O O O O I/O O I/O O I O I/O I/O I I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O Buffer LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL SSTL_2 SSTL_2 SSTL_2 SSTL_2 / LVCMOS SSTL_2 SSTL_2 SSTL_2 SSTL_2 SSTL_2 SSTL_2 SSTL_2 Analog SSTL_2 PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI LVTTL PCI LVTTL LVTTL LVTTL LVTTL LVTTL I/O Type High Drive High Drive High Drive High Drive High Drive High Drive High Drive High Drive STI Internal Resistor Notes1 pull-up DDR Bus PCI Bus Interface pull-up on board pull-up on board pull-up on board pull-up on board Open Collector pull-up on board pull-down on board pull-up on board pull-up on board pull-up on board pull-up pull-up pull-up pull-up pull-up on board pull-up on board pull-up on board pull-up on board pull-up on board2 pull-up on board2 General Purpose I/O Serial Peripheral Interface I2C-Bus Interface High Drive High Drive High Drive High Drive Low Drive/STI Low Drive/STI Table 2 Pin Characteristics (Part 1 of 2) 10 of 53 January 19, 2006 IDT RC32434 Function Ethernet Interfaces Pin Name MIICL MIICRS MIIRXCLK MIIRXD[3:0] MIIRXDV MIIRXER MIITXCLK MIITXD[3:0] MIITXENP MIITXER MIIMDC MIIMDIO JTAG_TMS EJTAG_TMS JTAG_TRST_N JTAG_TCK JTAG_TDO JTAG_TDI CLK EXTBCV EXTCLK COLDRSTN RSTN Type I I I I I I I O O O O I/O I I I I O I I I O I I/O Buffer LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL LVTTL I/O Type STI STI STI STI STI STI STI Low Drive Low Drive Low Drive Low Drive Low Drive STI STI STI STI Low Drive STI STI STI High Drive STI Low Drive / STI Internal Resistor pull-down pull-down pull-up pull-up pull-down pull-down pull-up Notes1 EJTAG / JTAG pull-up pull-up pull-up pull-up pull-up pull-up pull-down System pull-up pull-up on board Table 2 Pin Characteristics (Part 2 of 2) 1.

High to low transition time. Jitter. Amount of time the reference clock (or signal) edge can vary on either the rising or falling edges. Data out. Amount of time after the reference clock edge that the output will become valid. The minimum time represents the data output hold. The maximum time represents the earliest time the designer can use the data. Z state to data valid. Amount of time after the reference clock edge that the tri-stated output takes to become valid. Data valid to Z state. Amount of time after the reference clock edge that the valid output takes to become tri-stated. Input set-up. Amount of time before the reference clock edge that the input must be valid. Input hold. Amount of time after the reference clock edge that the input must remain valid. Pulse width. Amount of time the input or output is active for asynchronous signals. Slew rate. The rise or fall rate for a signal to go from a high to low, or low to high. Timing value. This notation represents a value of ‘X’ multiplied by the clock time period of the specified clock. Using 5(CLK) as an example: X = 5 and the oscillator clock (CLK) = 25MHz, then the timing value is 200. Skew. The amount of time two signal edges deviate from one another.
