A new series of tag chips by Impinj have been announced, the M830 and M850. These chips are said to be the most advanced tag chips that are currently on the market with a large amount of upgrades compared to the last set, the M700 series.
Impinj M700 series
The last release before the M800 series was the widely used M700 series. At the time of its release the M700 chips provided a high performance with a fast inventory capability and new advanced features that its predecessor did not. When implemented alongside a Impinj M700 RAIN RFID reader, the tags helped to improve the performance at a number of locations such as dock doors, conveyors, and store exits. This series of tag chips helped bring more alignment with the Internet of Things (IoT).
New Impinj M800 series
The new M800 series comes with two different memory configuration options so that they can meet the RAIN system application requirements. The memory for the M830 chip is a 128-bit EPC memory whilst the M850 chip has a 96-bit EPC memory and a 32-bit user memory. A goal with the introduction of the M800 series was to have it so that the same make of chip could be used in wider range of applications. These applications include most cases of retail, supply chains, logistics, and many more. With the release of the new set of chips came a new set of inlays to coincide and work with the next generation chips. Tageos and Beontag both released new inlays that feature the M800 very shortly after the M800 release.
M800 versus the M700
Whilst both of these designs are similar, there are some clear differences and benefits to the newer design the M800. For example, the M800 series has 30% lower power consumption, an improved tag readability with a wider tuning range, and a tighter radio frequency stability. The M800 series also has enhanced tag reliability due to a new chip shape that eliminates stress points and the enduro antenna pads that improve the chip-to-antenna connection. The new M800 series is also drop-in compatible with the M700 series meaning that the new series of chips can be quickly implemented into current systems. It seems that the main aims of the new series of next generation chips was to lower the power consumption whilst further increasing the functionality of the chips to be able to work more effectively on a wider range of applications.
