The EM1000 has several versions available. Device numbering scheme is as follows:
Examples of valid model numbers
Model number |
Description |
EM1000-512K-01 |
EM1000 module with 512KBytes of flash memory |
EM1000-1024K-S-01 |
EM1000 module with 1024KBytes of flash memory and the supercapacitor (backup power source for the RTC) |
EM1000-512K-SA-01 |
EM1000 module with 512KBytes of flash memory, supercapacitor, and SPI port header soldered in |
Earlier EM1000 modification -- EM1000-...-00 -- is no longer in production and have been superseded by newer "-01" devices.
Ordering an EM1000+WA1000 module kit
The EM1000 can also be ordered in combination with the WA1000 module. To simplify ordering, use the "EM1000W" ordering code. This code means that the EM1000 module will be supplied with the WA1000 module soldered into it (resulting mechanical structure is presented as "option B" on the Mechanical Dimensions drawing). Additional EM1000 "features" can be specified in the normal manner. For example, ordering code "EM1000W-512K-01" means that you will receive a set of two modules, one being "EM1000-512K-01", and another one being "WA1000-00", soldered together.

Notes:
| 1. | Automatic detection of "straight" and "cross" cable. |
| 2. | Actually a feature of TiOS firmware. |
| 3. | Not including the current consumed by slave SPI modules, such as the WA1000. |
| 4. | The RTC will not lose its data and will keep running as long as the backup voltage stays within this range. |
| 5. | As measured at room temperature, when the EM1000 is placed into a sealed contained without air convection. Temperature refers to the air temperature inside the container, not the surface temperature of any particular component of the EM1000. Measurement was performed without the SPI slave module installed. |
| 6. | The EM1000-xxxK-S device cannot be installed on the PCB directly. This is because it has a supercapacitor mounted on the bottom side of the module. This device must be be mounted on a socket. |
