around 1 mW when active, whereas the FPGA implementation stays between 6 and 9 mW
when active. When idle, the quiescent power of the CPLD is 0.05 mW and the FPGA has
standby=sleep modes dropping the power to 0.03 mW [43]. The direct ASIC implementation
drops the power consumed to 0.065mWwhen operating and to 0.0004mWwhen idle.
3.4.4.3 ISO 18000 Part 6C RFID Standard
ISO 18000 Part 6C standard [25] is a recent amendment to ISO 18000 Part 6 that describes
the RFID air interface for devices operating at 915 MHz and the associated communication
protocols used. Part 6C extends the existing Part 6 standard, which previously contained
type A and B devices with a type C modeled after the EPCGlobal Class 1 Generation 2
speci?¬?cation.
An interrogator manages tag populations using three basic operations, select, inventory,
and access. The Select command is applied successively to pick a particular tag population
based on user-speci?¬?c criteria, enabling union-, intersection-, and negation-based tag
