The UCODE EPC G2 IC is a dedicated chip for passive, intelligent tags and labels supporting the EPCglobal class 1 gen2 standard. It is especially suited for supply chain management and logistics applications where operating distances of several meters and high anti-collision rates are required.
Key features
• Interface fully compatible with UHF EPC G2 standard
• Long-range solutions (up to 7 m in the US and 6.6 m in Europe)
• Suitable for UHF RFID, allowing one tag to be used worldwide
• Fast data rate
- forward link: 40 - 160 kbits/s
- return link: 40 - 640 kbits/s
• Multi-label operation at 600 tags/sec in Europe, 1600 tags/sec in the US
• 512 bits of on-chip memory
- 96 bits EPC
- 32 bits Tag Identifier
- 128 bits programmable user memory
- 32 bits access password
- 32 bits kill password
• Runs on the same hardware infrastructure as the UCODE HSL and the UCODE EPC1.19
Key benefits
• Tags / labels and readers available from various suppliers
• First UHF EPC product operating worldwide
• Highly advanced anti-collision and highest identification speed
• Reliable and robust RFID technology suitable for dense reader and noisy environment
• Secure UHF communication; readers do not transmit EPC data
• Broadest industry back-up – EPCglobal and ISO 18000-6C
• Reader portfolio covers all regional demands
The UCODE EPC G2 IC is the first UHF EPC product from Philips. Designed specifically for long-range applications, the entire UCODE family also offers anti-collision and collision arbitration functionality. This allows a reader to simultaneously operate multiple labels / tags within its antenna field.
A UCODE EPC G2 based label / tag requires no external power supply. Its contactless interface generates the power supply via the antenna circuit by propagative energy transmission from the interrogator (read/write device), while the system clock is generated by an on-board oscillator. Data transmitted from interrogator to label / tag is demodulated by the interface, and it also modulates the interrogator’s electromagnetic field for data transmission from label / tag to interrogator.
A label / tag can be operated without the need for line of sight or battery, as long as it is connected to a dedicated antenna for the targeted frequency range.When the label / tag is within the interrogator’s operating range, the high-speed wireless interface allows data transmission in both directions.

The key the NFC CARD different parts of flash card are: the control chip, archiving memory and clock that also one of many symbols embodies the technical content in the whole flash card system. The chips used in the current flash cards divide into two categories, the first is ASIC chip. This sort of chip does not contain a lot of technology. Therefore, its functions are not strong and many cartridges don't support clock but has little battery consumptions and lower lever price.
