Interface and signal description4
4.1 Fast Ethernet LAN
The LAN1 and the LAN2 connector support 10 and 100 Mbit LAN.
4.2 USB host
The single USB Host connector does support USB2.0 connection with high speed up to
480Mbit/s and also full and low speed devices.
The power on the 5V line is equipped with a resettable fuse with 500mA.
4.3 USB device
The USB device connects the armStoneA5 as device on a PC.
4.4 microSD
The microSD push-push connector supports the SD Standard Host Specification Version 2.0
standard.

4.5 LVDS port connector
The single channel LVDS display port can be direct connected to a LVDS 18 bit display.
The VLCD voltage is 3.3V and switched on the baseboard. The current limit is 1.2 A.
Connector is a JAE FI-S25P-HFE. Matching connector on display cable is a crimp connector
FI-S25S housing and a cable with FI-C3-A1-15000 crimp contacts.
This connector is used because a wide range of displays does have a JAE FI-S series con-
nector (with different pinouts) and it's easy to handle identical crimp contacts for the cable
manufacturer.

VCC3.3
On default a 9 pin connector is mounted on pin 53..61 to use a COM port standard adapter
cable. Italic signals do have a 4k7 pull-up on the module.
!!! Pin 14 has a pull-down due to bug in processor revision. Will be changed to pull-up when
bug in processor is fixed.!!!

13
4.12.1 Audio
The feature connector provides Stereo Line in, Stereo Line out and microphone.
4.12.2 RS232 COM port
A 9 pin double row connector is mounted in pin 53..61. That allows to attach a standard 9pin
to DSUB9 adapter cable for debug output of bootloader and kernel with TX, RX, RTS and
CTS to a terminal.
Pin 1 of this adapter should connect on pin 53 of the 66 pin connector. Pin 62 is the key pin
and should be removed.
On pin 36 & 38 is a second RS232 COM port (RXD2/TXD2).
4.12.3 TTL COM port
There is additional serial port with 3.3V TTL level (RXD1/TXD1).
4.12.4 SPI
The module supports a HS SPI (Serial Peripheral Interface) with 2 chip selects. Signals are
3.3V compliant and have 4.7k pull-ups on module.
4.12.5 I2C
The module supports a I2C interface as I2C master. Signals are 3.3V compliant and have
4.7k pull-ups on module.
4.12.6 ADC In
4 ADC inputs (ADC_IN0..3)
Resolution: 12-bit
Differential Nonlinearity Error: ± 1.0 LSB (Max.)
Integral Nonlinearity Error: ± 4.0 LSB (Max.)
Maximum Conversion Rate: 0.5 MSPS
Analog Input Range: 0 ~ 3.3V
On-chip sample-and-hold function
4.12.7 PWM out
3 programmable PWM outputs (PWMOUT0..2) with 3.3V level in 16.1kHz up to 33 MHz fre-
quency range
4.12.8 Matrix keyboard
8x8 keyboard matrix (ROW0..7, COL0..1) with 3.3V level. The ROW signals have 4.7k pull-
ups on module.

14
4.12.9 GPIOs
GPIOs are programmable as Input or Output with 3.3V TTL level. The default maximum driv-
er current is 10mA (sink and source).
XGPIO0..9 have 4.7k pull-up on module.
!!! XGPIO9 has a pull-down due to bug in processor revision. Will be changed to pull-up
when bug in processor is fixed.!!!
4.12.10 MISC signals, power
RESETBTN 3.3V TTL low active RESET input; use pushbutton to GND or open
collector driver to pull low. Don’t drive with high level.
VCC3.3, VCC5 voltage outputs for external logic, max. 100mA per pin for external
chips and functions

15
4.12.11 CAN Bus
As an optional feature the module does provide the CAN bus transmit and receive TTL signal
without any termination in standard version (CANRX, CANTX). Both signals are working with
3.3V level.
Needs an interface chip to the CAN bus as shown below. If not used, please left signals un-
connected.

pins..
