Ordering Info and Specifications

Device numbering scheme is as follows:

"A" and "T" versions are not standard and cannot be ordered from our online store. Contact Tibbo if you wish to order EM2000 devices with "A" or "T" options.

If the flash memory size is omitted, the 1,024K option is implied.

To order the EM2000 in combination with the WA2000 Wi-Fi/BLE add-on module, use the "EM2000NC" ordering code for the WA2000C (chip antenna onboard), and "EM2000NU" ordering code for the WA2000U (coaxial connector for an external antenna). These codes mean that the EM2000 module will be supplied with the WA2000 add-on soldered into it (the resulting mechanical structure is presented as "option B" in the Mechanical Dimensions drawing).

Hardware Specifications

Ethernet interface

10/100BaseT Ethernet, Auto-MDIX, magnetics not built-in

Serial ports

Four 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.

All lines are 5V-tolerant.

40 lines are combined into five 8-bit ports.

Eight 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 external buzzer

Clock frequency (controlled programmatically)

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 the 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 Memory and EEPROM.


2,048 bytes, 2,020 bytes available for storing application data.

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

Nominal power supply voltage (VCC pin)

DC 3.3V, ±5%

Reset circuit trip voltage (VCC pin)

~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 (VCC pin), not including hardware consumed by an add-on modules plugged into the EM2000

100mA at full speed, 100BaseT Ethernet mode

Backup power voltage range (VCCB pin)

1.8V ~ 3.3V

Backup current (VCCB pin)

13µA when the EM2000 is not powered (0V on VCC)

Operating temperature

–40°C to +80°C
