Chip Features
- 64-bit memory array programmed by laser.
- Wide dynamic range in the chip buffer area.
- On-chip power and voltage limiter.
- On-chip full-wave rectifier converter.
- Low-impedance modulation driver with high modulation depth.
- Very small chip size, suitable for transplant applications.
- Integrated 480 pF resonant capacitor inside the chip.
- Integrated energy storage buffer capacitor inside the chip.
- Operating frequency range: 100–150 kHz, with a typical value of 125 kHz.
- Very low power consumption.
It uses Manchester modulation coding. In the typical mode, the ratio of the RF period to the data bit period is RF/64. When an AC induced voltage of at least 3.5 Vpp is generated at both ends of the external coil of the TK4100 chip, and the coil clock frequency is about 125 kHz, the chip powers on and starts working. The operating temperature range can reach -40°C to +85°C.
