The RC32300 implements the enhanced MIPS-II ISA and helps meet the real-time goals and maximize throughput of communications and consumer systems by providing capabilities such as a prefetch instruction, multiple DSP instructions, and cache locking. The instruction set is largely compatible with the MIPS32 instruction set, allowing the customer to select from a broad range of software and development tools. Cache locking guarantees real-time performance by holding critical code and parameters in the cache for immediate availability. The microprocessor also implements an on-chip MMU with a TLB, making the it fully compliant with the requirements of real time operating systems. Security Engine The RC32365 incorporates an on-chip security engine that has been designed to accelerate IPSec performance and minimize the amount of performance required by the CPU to process secure packet traffic. The engine includes hardware support for the DES, 3DES, and AES encryption algorithms and the MD5 and SHA1 hash functions. The engine also supports hardware-assisted packet processing for the various modes of IPSec, including AH, ESP, and AH+ESP tunnel and transport modes. Two dedicated DMA channels are used to transfer data to and from the security engine, allowing the CPU to work on other tasks during this time. 2 of 44 October 5, 2005 RC32365 Revision History PCI Interface The PCI interface on the RC32365 is compatible with version 2.2 of the PCI specification. An on-chip arbiter supports up to three external bus masters, supporting both fixed priority and rotating priority arbitration schemes. The RC32365 can support both satellite and host PCI configurations, enabling it 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 RC32365 device. PCMCIA Interface The RC32365 provides a "glueless" connection to a single PCMCIA I/O device via the memory and peripheral device controller. The PCMCIA interface allows the RC32365 to connect to various types of I/O peripherals including fax modems, storage devices, and wireless LAN chipsets. The RC32365 implementation provides a maximum throughput of 160 Mbps through the 16-bit wide interface as specified by the PCMCIA 2.1 Standard. March 17, 2003: Initial publication.

October 5, 2005: Removed 180 MHz speed grade. Ethernet Interface The RC32365 has two Ethernet Channels supporting 10Mbps and 100Mbps speeds and provides a standard media independent interface (MII) off-chip, allowing a wide range of external devices to be connected efficiently. Memory and I/O Controller The RC32365 incorporates a flexible memory and peripheral device controller providing direct support for SDRAM, Flash ROM, SRAM, PCMCIA, and other I/O devices. It can interface directly to 8-bit boot ROM for a very low cost system implementation. It also offers various trade-offs in cost / performance for the main memory architecture. The timers implemented on the RC32365 satisfy the requirements of most real time operating systems. DMA Controller The DMA controller off-loads the CPU core from moving data among the on-chip interfaces, external peripherals, and memory. The DMA controller supports scatter / gather DMA with no alignment restrictions, appropriate for communications and graphics systems. Enhanced JTAG Interface For system debugging, the RC32300 CPU core includes an Enhanced JTAG (EJTAG) interface which operates in Run-Time Mode. Thermal Considerations The RC32365 is guaranteed in a ambient temperature range of 0° to +70° C for commercial temperature devices and - 40° to +85° for industrial temperature devices. 3 of 44 October 5, 2005 RC32365 Pin Description Table The following table lists the functions of the pins provided on the RC32365.

Reset can occur through a pull-down resistor on JTAG_TRST_N if the probe is not connected. However, on-chip pull-up resistors are implemented on the RC32365 due to an IEEE 1149.1 requirement. Having on-chip pull-up and external pull-down resistors for the JTAG_TRST_N signal requires special care in the design to ensure that a valid logical level is provided to JTAG_TRST_N, such as using a small external pull-down resistor to ensure this level overrides the on-chip pull-up. An alternative is to use an active power-up reset circuit for JTAG_TRST_N, which drives JTAG_TRST_N low only at power-up and then holds JTAG_TRST_N high afterwards with a pull-up resistor. Figure 21 shows the electrical connection of the EJTAG probe target system connector. Pull-up RC32365 Pull-up VDD TRST* JTAG_TRST_N JTAG_TDI JTAG_TDO Series-res.

However, the recommended pull-up/down resistor is 1.0 kΩ because a low value reduces crosstalk on the cable to the connector, allowing higher JTAG_TCK frequencies. A typical value for the series resistor is 33 Ω. Recommended resistor values have ± 5% tolerance. If a probe is used, the pull-up resistor on JTAG_TDO must ensure that the JTAG_TDO level is high when no probe is connected and the JTAG_TDO output is tri-stated. This requirement allows reliable connection of the probe if it is hooked-up when the power is already on (hot plug). The pull-up resistor value of around 47 kΩ should be sufficient. Optional diodes to protect against overshoot and undershoot voltage can be added on the signals of the chip with EJTAG. If a probe is used, the RST* signal must have a pull-up resistor because it is controlled by an open-collector (OC) driver in the probe, and thus is actively pulled low only. The pull-up resistor is responsible for the high value when not driven by the probe of 25pF. The input on the target system reset circuit must be able to accept the rise time when the pull-up resistor charges the capacitance to a high logical level. Vcc I/O must connect to a voltage reference that drops rapidly to below 0.5V when the target system loses power, even with a capacitive load of 25pF. The probe can thus detect the lost power condition. For additional information on EJTAG, refer to Chapter 23 of the RC32365 User Reference Manual. 32 of 44 October 5, 2005 RC32365 Voltage Sense Signal Timing Trise_16f VSENSE Tactive Figure 22 Voltage Sense Signal Timing The target system must ensure that Trise is obeyed after the system reaches 0.5V (Tactive), so the probe can use this value to determine when the target has powered-up. The probe is allowed to measure the Trise time from a higher value than Tactive (but lower than Vcc I/O minimum) because the stable indication in this case comes later than the time when target power is guaranteed to be stable. If JTAG_TRST_N is asserted by a pulse at power-up, this reset must be completed after Trise. If JTAG_TRST_N is asserted by a pull-down resistor, the probe will control JTAG_TRST_N. At power-down, no power is indicated to the probe when Vcc I/O drops under the Tactive value, which the probe uses to stop driving the input signals, except for the probe RST*.

Inherently, PLL circuits are only capable of generating aligned clocks for master input clock (CLK) frequencies within a limited range. PLL Analog Filter The storage capacitor required for the Phase-Locked Loop circuit is contained in the RC32365. However, it is recommended that the system designer provide a filter network of passive components for the PLL power supply. VCCPLL (circuit power) and VSSPLL (circuit ground) should be isolated from VCC Core (core power) and VSS (common ground) with a filter circuit such as the one shown in Figure 24. 33 of 44 October 5, 2005 RC32365 Because the optimum values for the filter components depend upon the application and the system noise environment, these values should be considered as starting points for further experimentation within your specific application.

Power-on RampUp The 2.5V VccCore and VccPLL supplies can be fully powered without the 3.3V VccI/O supply. However, the VccI/O supply cannot exceed the VccCore and VccPLL supplies by more than 1 volt during power up. A sustained large power difference could potentially damage the part. Inputs should not be driven until the part is fully powered. Specifically, the input high voltages should not be applied until the VccI/O supply is powered. There is no special requirement for how fast VccI/O ramps up to 3.3V. However, all timing references are based on a stable VccI/O. 34 of 44 October 5, 2005 RC32365 DC Electrical Characteristics The values given below are based on systems running at recommended supply voltages, as shown in Table 14.
