SJ-467 Datasheet . High-noise-resistant PSK modulation: binary phase-shift keying (BPSK) for both reader-to-RFID and RFID-to-reader transmission. ~ Start-stop synchronization and half-duplex transmission with parity, 1 stop bit . High-efficiency power generation circuit using electromagnetic induction: battery less operation, full-wave rectifier circuit, shunt regulator . Data processing logic circuit: digital PLL, security circuit , High-reliability E2PROM: 4 Kbits Maximum write time: 7 ms (16-byte batch write) Overwrite: 100,000 times Data retention: 10 years ~ Selectable receive carrier frequency: 100 kHz t0 500 kHz (when external antenna circuit is used) * Programmable security circuit: security level can be set * High-speed transfer rate of 25 kbps: 1/16 0f receive carrier frequency = 400 kHz . High-speed multi-read of 32 IDs per second: when receive carrier frequency = 400 kHz (ID only read) * Supplied as chips or on wafer Chip thickness: 175 ym (typ.) SJ-467 on stock
Program memory consists of 768 x 8 ROM. These bytes of ROM may be instructions or constant data. The memory is addressed by the 15-bit program counter (PC). There are no "pages" of ROM, the PC counts all 15 bits. ROM can be in- directly read by the LAID instruction for table lookup. |
