Description

The H4001 is a CMOS integrated circuit for use in transponders. The circuit is powered by an external coil placed in a magnetic field, and gets its clock from the same field via one of the coil terminals. The other coil terminal is affected by the modulator, turning on and off the modulation current in order to send back the 64 bits of information contained in a factory pre-programmed memory array.

Features

■ 64 bit memory array laser programmable

■ Wide dynamic range due to on chip buffer capacitance & voltage limiter on chip.

■ Full wave rectifier on chip

■ Big modulation depth due to a low impedance modulation device

■ 50000 baud reading speed at 3 MHz

■ Very small chip size convenient for implantation

■ Unsensitive close to metal

■ Large distance even without resonance capacitor

■ No external buffer capacitance needed due to low power consumption
