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.

Typical value of inductance at 125 KHz is 2 mH

The capacitor is adjusted to the resonance

Fig. 1

The programming of the chip is performed by laser

fusing of polysilicon links in order to store a unique

code on each chip.

Pin Assignment

The serial output data string contains a 9 bits header,

40 bits of data, 14 parity bits, and 1 stop bit.

COIL 2

Due to the low power consumption of the logic core,

no supply buffer capacitor is required. Only an external

coil is required to obtain the chip function. A parallel

capacitor adjusted with the coil to obtain resonnance,

will increase the read distance.

Memory Array

The H4001 contains 64 bits divided in five groups of information. 9 bits are used for the header, 10 row parity bits

(P0 - P9), 4 column parity bits (PC0 - PC3), 40 data bits (D00 - D93), and 1 stop bit set to logic 0.

- 4 column even parity bits, NO row parity bit

The header is composed by the 9 first bits which are mask programmed to 111111111. Due to the data and parity

organisation, this sequence can not be reproduced in the data string. The header is followed by 10 groups of 4 data

bits and 1 even row parity bit. Then, the last group consists of 4 even column parity bits without row parity bit.

Bits D00 to D03 and bits D10 to D13 are customer specific identification.

These 64 bits are outputted serially in order to control the modulator used to modify the current at one of the coil

terminals.

When the 64 bits data string is outputted, the output sequence is repeated continuously until power goes off.

Control Logic

Two mask programmed versions of logic are available. The first one will modulate the amplitude of the magnetic field

with a bit rate corresponding to 64 periods of the field frequency (Manchester coding). The second version is using

half of the field frequency to transmit data by shifting the signal phase (PSK coding).

One of the coil terminals (COIL1 in Fig.6) is used to generate the clock signal for the logic. The output of the clock

extractor drives a sequencer providing all necessary signals to address the Memory Array, and serially output the

data.

PSK version

The serial data output of the Memory array connects the modulation control to the output or inverted output of a

flip-flop which input is the signal from the clock extractor.

When a logic 0 is output, the modulation control signal is changed to the other output of the flip-flop, and when a logic

1 is output, the modulation control signal remains on the same flip-flop output.

Data Modulator

The data modulator is controlled by the signal Modulation Control (see above fig. 4 & 5) in order to induce a high

current on COIL_2 terminal when this signal is at logic 0. This will affect the magnetic field according to the data

stored in the Memory Array.
