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Earlier EM1000 modification -- EM1000-...-00 -- is no longer in production and have been superseded by newer "-01" devices.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+GA1000 module combination
The EM1000 can also be ordered in combination with the GA1000 module. To simplify ordering, use the "EM1000G" ordering code. This code means that the EM1000 module will be supplied with the GA1000 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 "EM1000G-1024K-S-01" means that you will receive a set of two modules, one being "EM1000-1024K-S-01" (EM1000 with 1024K flash and supercapacitor), and another one being "GA1000", soldered together.

|
Notes:
| 1. | The RTC will not lose its data and will keep running as long as the backup voltage stays within this range. |
| 2. | 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. |
