JT6N78S
TOSHIBA CMOS Integrated Circuit Silicon Monolithic
JT6N78S
Single-Chip System LSI for RFID Card
The JT6N78S is a system LSI for radio frequency identification (RFID) wireless cards. The JT6N78S incorporates an analog circuit, a data processing circuit and data memory in a single chip.
Features
· · · · · 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: 1 Kbit Maximum write time: 7 ms (16-byte batch write) Overwrite: 100,000 times Data retention: 10 years Selectable receive carrier frequency: 120 kHz to 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 of 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 µm (typ.)
