RFID Tag and COB Development Guide with Microchip's RFID Devices

From Microchip Technology, Inc.
 

 
A passive RFID tag contains an RFID integrated circuit (IC), resonant capacitor (C), and antenna (L), as shown in Figure 1. The antenna and capacitor form a parallel LC resonant circuit. The LC circuit must be tuned to the reader?s carrier frequency for maximum performance (read range).
Products & Services
Erasable programmable read-only memory (EPROM) chips are programmable, reusable computer chips that can be erased using ultraviolet light and reprogrammed with a PROM programmer or PROM burner. Search by Specification | Learn more about EPROM
SRAM chips use static random access memory (SRAM), a type of memory that is faster, more reliable, and more expensive than DRAM. Unlike DRAM, SRAM does not need to be refreshed in order to prevent data loss; however, SRAM requires more power than DRAM. Learn more about SRAM Memory Chips
Memory chips are internal storage areas in computers. Although the term “memory chip” commonly refers to a computer's random access memory (RAM), this product area includes many different types of electronic data storage. Computer memory stores data electronically in cells. Without memory chips, a computer could not read programs or retain data. Search by Specification | Learn more about Memory Chips
Electrically erasable programmable read-only memory (EEPROM) chips are similar to PROM devices, but require only electricity to be erased. Search by Specification | Learn more about EEPROM
