1 Overview
2 Chip
2.1 EM4095
Use in an RFID basestation to perform the following functions:
- antenna driving with carrier frequency - AM modulation of the field for writable transponder - AM demodulation of the antenna signal modulation induced by the transponder communicate with a microprocessor via simple interface.
Features:
- Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency
- No external quartz required
- 100 to 150 kHz carrier frequency range
- Multiple transponder protocol compatibility (e.g. EM400X, EM4050, EM4150, EM4070, EM4170, EM4069)
- Sleep mode 1µA
- USB compatible power supply range
- Small outline plastic package SO16 or PSOP2 16
