Déi Low-Käschten T5577 Wafer, T5577 Chip, Wiertche widdersprach ATA5577 Wafer

The T5577 passive tag chip is specifically tailored for the low-cost, non-contact identity application market. The T5577 chip contains an ID-64 encoding format to comply with current de facto standards in the low-end access control market. Unlike the read-only access card chip EM4102, the T5577 chip provides a repeated erasing function, which is convenient for users to perform data writing and copying operations, and also has advanced functions such as password protection for the data area. The chip is a highly integrated, staark Leeschtung, low power read and write chip that enjoys a high reputation in the industry.
The T5577 chip requires no external power supply or external storage capacitors, supports Manchester 2K code modulation, and user data is stored in 512-bit non-volatile EEPROM internal memory.
