Notes * Power supply pins AVDD, AVss, XVDD, XVss, VDD and Vss should process all the pins. * PCMD is the MSB first, two's complement output. * GTOP is used to monitor the frame sync protection status. (High: sync protection window open.) * XUGF is the frame sync obtained from the EFM signal, and is negative pulse. It is the signal before sync protection. * XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the EFM signal transition point coincide. * The GFS signal goes high when the frame sync and the insertion timing match. * RFCK is derived from the crystal accuracy, and has a cycle of 136s (at normal speed). * C2PO represents the data error status. * XRAOF is generated when the 16K RAM exceeds the 4F jitter margin. -6- CXP402 Input/Output Circuit Formats for Pins Pin Port A Port B Ports A, B data Circuit format When reset PA0 to PA3 PB0 to PB3 Ports A, B I/O direction Input protection circuit Hi-Z IP Data bus RD (Ports A, B) 8 pins Port C Pull-up transistor approx. 50k Port C data PC0 to PC3 Port C I/O direction Hi-Z IP Data bus RD (Port C) 4 pins Pull-up transistor approx. 50k RMC XRST SEIN CNIN VCKI FOK LRCKI PCMDI BCKI EXCK 10 pins Schmitt input IP Internal circuit Hi-Z EMPHI is not Schmitt input. -7- CXP402 Pin Circuit format When reset VCH SEG0 to SEG15 VDD level VCL 16 pins VDD COM0 COM1 COM2 COM3 VLC1 VDD level VLC2 4 pins VLC3 VLC1 VLC2 VLC3 IP Internal resistor approx. 20k VLC1 = 3/4VDD VLC2 = 2/4VDD VLC3 = 1/4VDD (when pins left open) 3 pins XVDD XVDD XTAI XTAO XVSS XTAI Oscillation XVSS 4 pins XTAO -8- CXP402 Pin Circuit format When reset PCO MDP VPCO1 VPCO2 4 pins -- MDS MDS -- Output enable 1 pin VCTL FILI CLTV RF BIAS ASYI 6 pins IP Poly resistor -- AIN1 AIN2 IP -- 2 pins AOUT1 AOUT2 LOUT1 LOUT2 4 pins -- -9- CXP402 Pin DATO XLTO CLKO LOCK MON V16M FILO ASYO XRSTO LRCK PCMD BCK GTOP XPCK GFS RFCK C2PO XROF MNT3 MNT1 MNT0 C4M DOUT EMPH WFCK SCOR SBSO 27 pins Circuit format When reset -- - 10 - CXP402 Absolute Maximum Ratings Item Supply voltage LCD bias voltage Input voltage Output voltage High level output current High level total output current Low level output current Low level total output current Operating temperature Storage temperature Allowable power dissipation VDD VLC1, VLC2, VLC3 VIN VOUT IOH IOH IOL IOL Topr Tstg PD Symbol Ratings -0.3 to +7.01 -0.3 to +7.02 -0.3 to +7.02 -0.3 to +7.02 -5 -70 15 100 -20 to +75 -40 to +125 600 Unit V V V V mA mA mA mA C C mW (Vss = 0V reference) Remarks Output pin (value per pin) Total of output pins Output pin (value per pin) Total of output pins 1 The potential difference between analog power supplies AVDD, AVss, the oscillation power supplies XVDD, XVss and VDD, Vss should be within 0.3V. 2 VLC1, VLC2, VLC3, VIN and VOUT should not exceed VDD + 0.3V.
