description
ThunderLAN is a high-speed networking architecture that provides a complete PCI-to-10 Base-T/AUI Ethernet
solution. The TNETE110A, one implementation of the ThunderLAN architecture, is an intelligent protocol
network interface. The ThunderLAN SRAM FIFO-based architecture eliminates the need for external memory
and offers a single-chip glueless PCI-to-10 Base-T/AUI (IEEE 802.3) solution with an on-board physical layer
interface. See Figure 1.
The glueless PCI interface supports 32-bit streaming, operates at speeds up to 33 MHz and is capable of
internal data-transfer rates up to 2 Gbps, taking full advantage of all available PCI bandwidth. The TNETE110A
offers jumperless autoconfiguration using PCI configuration read / write cycles. Customizable configuration
registers, which can be autoloaded from an external serial EEPROM, allow designers of TNETE110A-based
systems to give their systems a unique identification code. The TNETE110A PCI interface, developed in
conjunction with other leaders in the semiconductor and computer industries, has been vigorously tested on
multiple platforms to ensure compatibility across a wide array of available PCI products. In addition, the
ThunderLAN drivers and ThunderLAN architecture use TI’s patented adaptive performance optimization (APO)
technology to dynamically adjust critical parameters for minimum latency, minimum host CPU utilization, and
maximum system performance. This technology ensures that the maximum capabilities of the PCI interface are
used by automatically tuning the adapter to the specific system in which it is operating.
An intelligent protocol handler (PH) implements the serial protocols of the network. The PH is designed for
minimum overhead related to multiple protocols, using common state machines to implement 95 percent of the
total protocol handler. On transmit, the PH serializes data, adds framing and cyclic redundancy check (CRC)
fields, and interfaces to the network physical layer (PHY) chip. On receive, it provides address recognition, CRC
and error checking, frame disassembly, and deserialization. Data for multiple channels is passed to and from
the PH by way of circular-buffer FIFOs in the FIFO SRAM.
Compliant with IEEE Standard 1149.1, the TNETE110A provides a 5-pin test-access port that is used for
boundary-scan testing.
The TNETE110A is available in a 144-pin quad flat package and thin quad flat package.
differences between TNETE110 and TNETE110A:
The TNETE110A implements the CIS pointer register as defined in the PC card standard. This register can be
found in the PCI configuration registers at offset 28h. For other differences between the TNETE110 and
TNETE110A, consult the ThunderLAN Programmer’s Guide (literature number SPWU013).

PDEVSEL
21
I/O
PCI device select. PDEVSEL indicates that the driving device has decoded one of its addresses as
the target of the current access. The TNETE110A drives PDEVSEL when it decodes an access to one
of its registers. As a bus master, the TNETE110A monitors PDEVSEL to detect accesses to illegal
memory addresses.
PFRAME
17
I/O
PCI cycle frame. PFRAME is driven by the active bus master to indicate the beginning and duration
of an access. PFRAME is asserted to indicate the start of a bus transaction and remains asserted
during the transaction, only being deasserted in the final data phase.
PGNT
132
I
PCI bus grant. PGNT is asserted by the system arbiter to indicate that the TNETE110A has been
granted control of the PCI bus.
4
I
PCI initialization device select. PIDSEL is the chip select for access to PCI configuration registers.
128
O/D
PCI interrupt. PINTA is the interrupt request from the TNETE110A. PCI interrupts are shared, so this
is an open-drain (wired-OR) output.
I/O
PCI initiator ready. PIRDY is driven by the active bus master to indicate that it is ready to complete the
current data phase of a transaction. A data phase is not completed until both PIRDY and PTRDY are
sampled asserted. When the TNETE110A is a bus master, it uses PIRDY to align incoming data on
reads or outgoing data on writes with its internal RAM-access synchronization (maximum one cycle
at the beginning of burst). When the TNETE110A is a bus slave, it extends the access appropriately
until both PIRDY and PTRDY are asserted.
PIDSEL
PINTA
PIRDY
19
PTRDY
20
I/O
PCI target ready. PTRDY is driven by the selected device (bus slave or target) to indicate that it is ready
to complete the current data phase of a transaction. A data phase is not completed until both PIRDY
and PTRDY are sampled asserted.
ThunderLAN uses PTRDY to ensure every direct I/O (DIO) operation is correctly interlocked.
PPAR
27
I/O
PCI parity. PPAR carries even parity across PAD[31:0] and PC / BE[3:0]. It is driven by the TNETE110A
during all address and write cycles as a bus master and during all read cycles as a bus slave.
PPERR
24
I/O
PCI parity error. PPERR indicates a data parity error on all PCI transactions except special cycles.

I/O
EPROM address / data. EAD[7:0] is a multiplexed byte bus that is used to address and read data from
an external BIOS ROM.
• On the cycle when EXLE is asserted low, EAD[7:0] is driven with the high byte of the
address.
• On the cycle when EALE is asserted low, EAD[7:0] is driven with the low byte of the
address.
• When EOE is asserted, BIOS ROM data should be placed on the bus.
These pins can also be used to drive external status LEDs. Low-current (2 – 5 mA) LEDs can be
connected directly (through appropriate resistors). High-current LEDs can be driven through buffers
or from the BIOS ROM address latches.
EALE

PCI interface (PCIIF)
The TNETE110A PCIIF contains a byte-aligning DMA controller that allows frames to be fragmented into any
byte length and transferred to any byte address while supporting 32-bit data streaming. For multipriority
networks it can provide multiple data channels, each with separate lists, commands, and status. Data for the
channels is passed to and from the PH by way of circular buffer FIFOs in the SRAM, controlled through FIFO
registers. The configuration EEPROM interface (CEI), BIOS ROM /LED driver interface (BRI), configuration and
I / O memory registers (CIOREGS), and DMA controller are subblocks of the PCIIF. The features of these
subblocks are as follows:
configuration EEPROM interface (CEI)
The CEI provides a means for autoconfiguration of the PCI configuration registers. Certain registers in the PCI
configuration space may be loaded using the CEI. Autoconfiguration allows builders of TNETE110A-based
systems to customize the contents of these registers to identify their own system, rather than using the TI
defaults. The EEPROM is read at power up and can then be read from, and written to, under program control.
BIOS ROM/LED driver interface (BRI)
The BRI addresses and reads data from an external BIOS ROM via a multiplexed byte-wide bus. The ROM
address/ data pins can also be multiplexed to drive external status LEDs.
configuration and I/O memory registers (CIOREGS)
The CIOREGS reside in the configuration space, which is 256 bytes in length. The first 64 bytes of the
configuration space is the header region, which is explicitly defined by the PCI standard.
DMA controller (DMAC)
The DMAC is responsible for coordinating TNETE110A requests for mastership of the PCI bus. The DMAC
provides byte-aligning DMA control allowing byte-size fragmented frames to be transferred to any byte address
while supporting 32-bit data streaming.
protocol handler (PH)
The PH implements the serial protocols of the network. On transmit, it serializes data, adds framing and CRC
fields, and interfaces to the network PHY. On receive, it provides address recognition, CRC and error checking,
frame disassembly, and deserialization. Data for multiple channels is passed to and from the PH by way of
circular buffer FIFOs in the FSRAM controlled through FPREGS.
10 Base-T physical layer (PHY)
The PHY acts as an on-chip front-end providing physical layer functions for 10 Base-5 (AUI), 10 Base-2, and
10 Base-T (twisted pair). The PHY provides Manchester encoding / decoding from smart squelch, jabber
detection, link pulse detection, autopolarity control, 10 Base-T transmission waveshaping, and antialiasing
filtering. Connection to the AUI drop cable for the 10 Base-T twisted pair is made via simple isolation
transformers (see Figure 2) and no external filter networks are required. Suitable external termination
components allow the use of either shielded or unshielded twisted-pair cable (150 W or 100 W). Some of the
key features of the on-chip PHY include the following:

FIFO pointer registers (FPREGS)
The FPREGS are used to implement circular buffer FIFOs in the SRAM. They are a collection of pointer and
counter registers used to maintain the FIFO operation. Both the PCIIF and PH use FPREGS to determine where
to read or write data in the SRAM and to determine how much data the FIFO contains.
FIFO SRAM (FSRAM)
The FSRAM is a conventional SRAM array accessed synchronously to the PCI bus clock. Access to the RAM
is allocated on a time-division multiplexed (TDM) basis, rather than through a conventional shared bus. This
removes the need for bus arbitration and provides ensured bandwidth. Half of the RAM accesses (every other
cycle) are allocated to the PCI controller. It has a 64-bit access port to the RAM, giving it 1 Gbps of bandwidth,
sufficient to support 32-bit data streaming on the PCI bus. The PH has one quarter of the RAM accesses, and
its port may be up to 64 bits wide. A 64-bit port for the PH provides 512 Mbps of bandwidth, more than sufficient
for a full-duplex 100-Mbps network. The remaining RAM accesses can be allocated toward providing even more
PH bandwidth. The RAM also is accessible (for diagnostic purposes) from the TNETE110A internal data bus.
Host DIO (mapped I / O) accesses are used by the host to access internal TNETE110A registers and for adapter
test.
Some of the features of the FSRAM follow:

3.375K bytes of FSRAM
1.5K-byte FIFO for receive channel
One 1.5K-byte FIFO for transmit channel
Three 128-byte lists
Supporting 1.5K byte of FIFO per channel allows full-frame buffering of Ethernet frames.
test-access port (TAP)
Compliant with IEEE Standard 1149.1, the TAP is composed of five pins that are used to interface serially with
the device and the board on which it is installed for boundary-scan testing.

PARAMETER MEASUREMENT INFORMATION
Outputs are driven to a minimum high-logic level of 2.4 V and to a maximum low-logic level of 0.6 V. These levels
are compatible with TTL devices.
Output transition times are specified as follows: For a high-to-low transition on either an input or output signal,
the level at which the signal is said to be no longer high is 2 V and the level at which the signal is said to be low
is 0.8 V. For a low-to-high transition, the level at which the signal is said to be no longer low is 0.8 V and the level
at which the signal is said to be high is 2 V, as shown below.
The rise and fall times are not specified but are assumed to be those of standard TTL devices, which are typically
1.5 ns.
