Manufacturer: Atmel (now Microchip Technology)

General Description

The ATA5558 is a contactless, two-terminal R/W-Identification IC (IDIC®) for multi- or single tag applications in the low frequency (≈ 125 kHz) range.

The passive tag uses the external RF signal to generate it’s own power supply and internal clock reference.
