Ordering Info and Specifications

Top  Previous  Next

To order, use the "EM2001" ordering code.

To order the EM2001 in combination with the GA1000 module, use the "EM2001G" ordering code.

Hardware specifications

Ethernet interface

10/100BaseT Ethernet, Auto-MDIX, with RJ45/magnetics

Serial ports

4 ports, CMOS-level

UART capabilities

Baudrates up to 460'800bps; none/even/odd/mark/space parity and 7/8 bits/character (7 bits/character and "none" parity cannot be used together)

Number of I/O lines

56 lines (including 5 on the wireless add-on connector);

all lines are 5V-tolerant;

40 of I/O lines are combined into five 8-bit ports;

8 lines can be used as interrupt lines.

Max. load current for each I/O line


Square wave generator

458Hz - 15MHz (with the full-speed clock), primarily intended for driving an external buzzer

Real-time counter (RTC)


RTC backup power source

Onboard coin cell

Clock frequency

120MHz at full speed

34MHz at medium speed

16MHz at low speed

Program flash memory

1MB program flash for TiOS and compiled application binary. TiOS occupies 256KB. The remaining 768KB can be used to store the compiled application binary and permanent (unchangeable) data.

Flash disk

1MB for hardened, fault-tolerant file system. The entire disk can be used by the application to store its data .

Typical write endurance is 100'000 write cycles per 256-byte sector. See the warning in Flash and EEPROM Memory.

EEPROM memory

2048 bytes, 2020 bytes available for storing application's data.

Typical write endurance is around 1'000'000 write cycles per 16-byte EEPROM sector. See Prolonging and Estimating EEPROM life.

Switching regulator supply voltage (supplied via the power jack or VIN pin)

unregulated, 8-20V input range, 12V nominal

Direct system power (supplied via the 3.3V pin bypassing the switching regulator)

regulated, 3.3V +/- 10%

Available current on the 3.3V pin (when powering through the voltage regulator)

1.0A if the GA1000 is used

1.3A if the GA1000 is not used

Reset circuit trip voltage (3.3V system power line)

~2.95V on power-up (i.e. when the voltage on VCC is rising)

~2.85V on brown-out (i.e. when the voltage on VCC is dropping)

Operating current when the 3.3V is supplied directly through the 3.3V pin

100mA at full speed, 100BaseT Ethernet mode

Operating temperature

-40 to +80 degrees C

Operating relative humidity


Mechanical dimensions (excluding RJ45 and power jack)

EM2001: 75x36x17.5mm

EM2001G: 75x36x19mm
