3 (9) e5530 rev. a6, 10-dec-01 functional description read operation after power up, once the e5530 has detected the incoming rf field, the ic continuously transmits the identification code as long as the rf signal is applied. the transition from the last bit to bit 1 of the next sequence occurs without interruption. data is transmitted by damping the incoming rf signal by an internal load. this load changes are detected by the reader station. different kinds of modulation and bitrates are optionally available. rectifier for internal power supply, an on-chip bridge rectifier is used which consists of two diodes and two n-channel transistors. a zener diode, which protects the circuit against overvoltage on the coil inputs, and a smoothing capacitor for the internal supply are also provided. damping load incoming rf will be damped by the power consumption of the ic itself and by an inter- nal load, which is controlled by the modulator. the loads are p-channel transistors connected between v dd and the coil inputs. the idic includes mask options for the load circuit: single-side, double-side and alter- nate-side modulation. there are four modulation methods available which can be selected by fuses. the cor- responding timing diagram is shown in figure 5. fsk modulation logical data ? 1 ? and ? 0 ? are represented as two different frequencies of damping. the frequency for ? 1 ? is rf divided by 10, a ? 0 ? divides rf by 8. psk modulation the external coil is damped with a carrier frequency of rf/2. a logical ? 1 ? causes (at the end of the bit period) a 180 phase shift on the carrier frequency, while a logical ? 0 ? causes no phase shift. biphase modulation logical ? 1 ? produces a signal which is the same as the internal bitclock. a logical ? 0 ? pro- duces no signal change in the middle of the bit period. manchester modulation a logical ? 1 ? causes a rising edge in the middle of a bit period (i.e., switch damping off), while a logical ? 0 ? causes a falling edge (i.e., switch damping on). a combination of biphase- and fsk-modulation is also optionally available. the avail- able combinations between the modulation types and the bitrates are shown in table ? transmission options ? . table 1. transmission options modulation carrier frequency (cf) bitrate [bit/s] fsk rf/8, rf/10 rf/32, rf/40, rf/50, rf/64, rf/80, rf/100, rf/128 psk rf/2 cf/4, 8, 16, 32 biphase rf/8, rf/16, rf/32, rf/64, rf/100, rf/128 manchester rf/8, rf/16, rf/32, rf/64, rf/100, rf/128
4 (9) e5530 rev. a6, 10-dec-01 figure 5. timing diagram for modulation options reading distances the e5530 is able to operate from very weak fields. nevertheless, there are some gen- eral rules which influence the achievable reading distance. best results are accomplished when the transponder points towards the reader coil. the transponder should not be embedded in metal, which will reduce the applicable magnetic field and thus the reading distance. the strength of the generated magnetic field and the sensitivity of the demodulator are the most important factors for a good reading distance. figure 6. example for a 64-bit code the identification code is transmitted continously. after the rf field is applied, the e5530h-232 starts with the first bit (msb) of the header byte ? e6hex ? ( ? 1110 0110 ? ), fol- lowed by a unique 56-bit serial number. no checksum is included in this sample code. pulsing the rf field may reduce the synchronization task as the first byte transmitted is known already (i.e., e6hex). this is even feasible, if the first bit may be lost due to reader synchronization problems. customer id code selection in general the customer may choose any id code suitable to his application. to avoid code duplication, atmel will define a fixed header ? i.e, the first 8 bits of the code ? for each customer. bitclk data psk fsk biph man 1 11 1 000 e6 header 56-bit id code 00 00 00 10 2d 72 5d
