The TX27 is the first member of a module series, specially designed for
Freescales i.MX multimedia processors. TX modules are complete computers,
implemented on a board smaller than a credit card, and ready to be designed
into your embedded system. TX modules includes a Freescale® i.MX
processor, SDRAM and Flash memory. The integrated LCD-controller enables
direct connection of an LCD screen, and the standard PCMCIA interface
High-Speed communication interfaces incl. onboard PHY allows direct use of
permits simple extension and integration into a target system. The TX27 is
connectors/magnetics on the baseboard without the need for additional logic:
specifically targeted at embedded applications where size, high cpuperformance and low power consumption are critical factors.

•
i.MX27
1-cell Li-Ion/Polymer (3.1V to 4.2V)
5.0V USB supply or AC wall adapter

Up to 1A output current 1.8V and 3.3V power supply outputs of the TX27 can
also be used on the baseboard.
Derived from the popular i.MX21 processor, the i.MX27 processor adds an
h.264 D1 hardware codec for high-resolution video processing, an Ethernet
10/100 MAC, security, plug-and-play connectivity and more power
management features.

This is an active high push button input which can be used to signal
PWR_ON and PWR_OFF events to the CPU by controlling the PMIC
ext_wakup signal and select contents of PMIC register 8H'88.
Connected to a GPIO.
Reset Output - active low output: can be caused by all reset source:
power on reset, system reset (RESET_IN), and watchdog reset.
Power On Reset—Active low input signal. Typically a push button
reset or driven by an open collector output. This signal is also driven
low by BATT_FLT. Please refer to the PMIC datasheet for details.
Leave unconnected, if not used.
Master Reset—External active low Schmitt trigger input signal. When
this signal goes active, all modules (except the reset module,
SDRAMC module, and the clock control module) are reset.

Active low external enable byte signal that controls D [15:8], shared
with PCMCIA PC_REG.
Active low external enable byte signal that controls D [7:0], shared
with PCMCIA PC_IORD.
Memory Output Enable—Active low output enables external data bus,
shared with PCMCIA PC_IOWR.
Active low signal sent by flash device causing external burst device to
latch the starting burst address.
RW signal—Indicates whether external access is a read (high) or
write (low) cycle. This signal is also shared with the PCMCIA PC_WE.
Clock signal sent to external synchronous memories (such as burst
flash) during burst mode.
