CPU Execution Core
The RC32365 is built around the RC32300 32-bit high performance
microprocessor core. 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.

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.
May 15, 2003: Removed “write protect capability” from features of
the SDRAM Controller.
July 9, 2003: In Table 6, changed values for RSTN (output).
Changed values in Tables 7, 8, 9, 10, and 17.
October 3, 2003: Added 180 MHz speed grade. Changed min
values in Table 7 from 1.8 to 1.2 for all signals except SDCLKINP and
SDCKENP. Changed min values for Tdo 10b and 10c in Table 10 for
PCIBEN, etc. and PCIGNTN/PCIREQN from 2.0 to 1.5.
February 25, 2004: Deleted reference to RNGCLK in Table 1
(GPIO[6]) and Table 22.
May 25, 2004: In Table 9, signals MIIxRXCLK and MIIxTXCLK, 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.
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.

RC32365
Boot Configuration Vector
The boot configuration vector is read into the RC32365 during cold reset. The vector defines parameters in the RC32365 that are essential to operation when cold reset is complete.
The encoding of boot configuration vector is described in Table 3, and the vector input is illustrated in Figure 4.
Signal
Name/Description
MDATA[2:0]
CPU Clock Multiplier. This field specifies the value by which the PLL multiplies the master
clock input (CLK) to obtain the processor clock frequency (PCLK).
0x0 - Multiply by 2
0x1 - 0x7 — Reserved
MDATA[3]
Endian. This bit specifies the endianness.
0x0 - little endian
0x1 - big endian
MDATA[4]
Reserved. This pin may be driven high or low during boot configuration and its state is
recorded in the Boot Configuration Vector (BCV) field of the BCV register. This reserved bit
may be used to pass boot configuration parameters to software.
MDATA[6:5]
Boot Device Width. This field specifies the width of the boot device (i.e., Device 0).
0x0 - 8-bit boot device width
0x1 - 16-bit boot device width
0x2 - 32-bit boot device width
0x3 - reserved

Reset Mode. This bit specifies the length of time the RSTN signal is driven.
0x0 - Normal reset: RSTN driven for minimum of 4096 clock cycles
0x1 - reserved
MDATA[8]
Disable Watchdog Timer. When this bit is set, the watchdog timer is disabled following a cold
reset.
0x0 - Watchdog timer is enabled
0x1 - Watchdog timer is disabled
MDATA[11:9]
PCI Mode. This bit controls the operating mode of the PCI bus interface. The initial value of the
EN bit in the PCIC register is determined by the PCI mode.
0x0 - Disabled (EN initial value is zero)
0x1 - PCI satellite mode with PCI target not ready (EN initial value is one)
0x2 - PCI satellite mode with suspended CPU execution (EN initial value is one)
0x3 - PCI host mode with external arbiter (EN initial value is zero)
0x4 - PCI host mode with internal arbiter using fixed priority arbitration algorithm
(EN initial value is zero)
0x5 - PCI host mode with internal arbiter using round robin arbitration algorithm
(EN initial value is zero)
0x6 - reserved
0x7 - reserved
MDATA[15:12]
Reserved. These pins may be driven high or low during boot configuration and their state is
recorded in the Boot Configuration Vector (BCV) field of the BCV register. These reserved bits
may be used to pass boot configuration parameters to software.

Clock low. Amount of time the clock is low in one clock period.
Thigh
Clock high. Amount of time the clock is high in one clock period.
Trise
Rise time. Low to high transition time.
Tfall
Fall time. High to low transition time.
Tjitter
Jitter. Amount of time the reference clock (or signal) edge can vary on either the rising or falling edges.
Tdo
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.
Tzd
Z state to data valid. Amount of time after the reference clock edge that the tri-stated output takes to become valid.
Tdz
Data valid to Z state. Amount of time after the reference clock edge that the valid output takes to become tri-stated.
Tsu
Input set-up. Amount of time before the reference clock edge that the input must be valid.
Thld
Input hold. Amount of time after the reference clock edge that the input must remain valid.
Tpw
Pulse width. Amount of time the input or output is active for asynchronous signals.
Tslew
Slew rate. The rise or fall rate for a signal to go from a high to low, or low to high.
X(clock)
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.
Tskew
Skew. The amount of time two signal edges deviate from one another.

1.
COLDRSTN asserted by external logic.
2.
RC32365 asserts RSTN, asserts BOEN[0] low, drives BDIRN low, and tri-states the data bus in response.
3.
External logic begins driving valid boot configuration vector on the data bus, and the RC32365 starts sampling it.
4.
External logic negates COLDRSTN and tri-states the boot configuration vector on MDATA[15:0]. The boot configuration vector must not be tri-stated before COLDRSTN is deasserted. The RC32365 stops sampling the boot configuration vector.
5.
The RC32365 starts driving the data bus, MDATA[31:0], deasserts BOEN[0] high, and drives BDIRN high.
6.
SYSCLK may be held constant after this point if Hold SYSCLK Constant is selected in the boot configuration vector.
7.
RSTN negated by the RC32365.
8.
CPU begins executing by taking MIPS reset exception, and the RC32365 starts sampling RSTN as a warm reset input.

1. The RC32365 provides bus turnaround cycles to prevent bus contention when going from a read to write and write to read. For example,
there are no cycles where an external device and the RC32365 are both driving. See Chapter 6, Device Controller, in the RC32365
User Reference Manual.
2. The values
for this symbol were determined by calculation, not by testing.
3.
WAITACKN must meet the setup and hold times if it is synchronous or the minimum pulse width if it is asynchronous.
4.
CEN1, CEN2, REGN, IORDN, and IOWRN are alternate functions of GPIO[12:8].

RC32365
The IEEE 1149.1 specification requires that the JTAG and EJTAG TAP controllers be reset at power-up whether or not the interfaces are used for
a boundary scan or a probe. 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.

Figure 21 Target System Electrical EJTAG Connection
Using the EJTAG Probe
In Figure 21, the pull-up resistors for JTAG_TDO and RST*, the pull-down resistor for JTAG_TRST_N, and the series resistor for JTAG_TDO must
be adjusted to the specific design. 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.

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*.

Phase-Locked Loop (PLL)
The processor aligns the pipeline clock, PClock, to the master input clock (CLK) by using an internal phase-locked loop (PLL) circuit that generates
aligned clocks. 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.
