TME-2001 Data Sheet
PCI Express Controller
Dual Programmable
Timer for PCI Express
Model TME-2001
The TME-2001 is a PCIexpress (PCIe) local bus
controller designed to replace Logical’s TMI-2001 PCI
controller for use in newer platforms with a PCIe bus.
Like the TMI-2001, the TME-2001 has two
independent program-controlled timers. Each timer
can be programmed to generate a PCIe local bus
interrupt at the completion of the selected time interval.
Two pulse timer output signals are provided for user
connection to external equipment. The outputs can be
programmed for positive or negative polarity and pulse
width duration. Each pulse timer can be coupled with
an interval timer to generate a repeating pulse that
occurs whenever the internal timer overflows.
Two user input signals are also available for
generation of one or two PCIe local bus interrupts from
an external source(s). The input signals can be
programmed for positive or negative edge detection.
Software, connector and signal compatible with
Logical’s TMI-2001 timer.
Features
Two Independent Timers. Each timer can be
independently programmed for an interval ranging
from 50 microseconds to over 214 seconds in
increments of 50 nanoseconds.
Two User Output Signals. One output signal is
provided from each pulse timer for user connection to
external equipment. The two output signals are user
programmable for a pulse width from 100
nanoseconds to 3.276 milliseconds in increments of 50
nanoseconds and are available to the user from an onboard DE9 connector.
Two User Input Signals. Two user input signals are
provided for generation of one or two PCIe local bus
interrupts from external sources. The two input signals
are user programmable and are available to the user
from an on-board mounted DE9 connector.
Easy to maintain. A module exerciser supplied with
any purchased device driver allows the user to verify
TME-2001 operation.

Nine user signals: PULSEA,
PULSEB, EXTINTA,
EXTINTB, EXTINTB1 and
four GND pins
DE9-S
TTL, Open collector,
180/390 termination. Input
signal EXTINTB1 has a 1K
ohm series resistor and can
receive input level in the
range of ±12V (such as the
RS-232 input). EXTINTB
and EXTINTB1 are two
sources for the same input
signals and each can
receive a different electrical
level, but only one signal
may be used at a time.
