The CSC0101A supports two hot-pluggable and hot-swappable PS/2 ports with either port can accept mouse or keyboard. It is ideal for the legacy system support, enabling seamless connections of traditional PS/2 interfaces devices of mouse and keyboard to USB. The CSC0101A is a USB 1.1 low-speed compliant device that interfaces to PS/2, it support the Human Interface Device (HID) class specification. The CSC0101A handles the merging of the PS/2 data and sends the data to the host system via the USB port Block Diagram 2004/May V1.40 www.allytek.com 4 CHESEN www.allytek.com CSC0101A Dual PS/2 to USB Data Converter Controller Pin Configurations Dice 2004/May V1.40 www.allytek.com 5 CHESEN www.allytek.com CSC0101A Dual PS/2 to USB Data Converter Controller SOP 16 Pins CSC0101A-S16 2004/May V1.40 www.allytek.com 6 www.allytek.com CHESEN CSC0101A Dual PS/2 to USB Data Converter Controller Pin Descriptions CSC0101A PAD # NAME 2 P31 3 P32 4 P33 5 P34 8 RESETB 10 P01 37 M1 38 VCC 40 OSCO 41 OSCI 42 SMT_SEL 43 GND 44 M0 45 VCP 46 IVCC 47 D+ 48 D- IN/OUT I/O I/O I/O I/O I I I P O I I P I O I I/O I/O DESCRIPTION PS/2 data for mouse PS/2 clock for mouse PS/2 clock for keyboard PS/2 data for keyboard External reset Test input Mode selection input 1 Power supply Crystal/Ceramic resonator out Crystal/Ceramic resonator in Force Ground Ground Mode selection input 0 USB Driver 3.3V 3.3V input USB data+ USB data- CSC0101A-S16 PIN # NAME 1 GND 2 VCP 3 D+ 4 D5 P31 6 P32 7 RESETB 8 P01 9 P34 10 P33 11 M0 12 M1 13 NC 14 VCC 15 OSCO 16 OSCI IN/OUT P O I/O I/O I/O I/O I I I/O I/O I I -P O I DESCRIPTION Ground USB Driver 3.3V USB data+ USB dataPS/2 data PS/2 clock External reset Test input PS/2 data PS/2 clock Mode selection input 0 Mode selection input 1 No Connect Power supply Crystal/Ceramic resonator out Crystal/Ceramic resonator in M1 GND GND VCC 2004/May M0 GND VCC VCC Suitable PS/2 Devices Legacy PS/2 mouse and keyboard with key de-bouncing Legacy PS/2 mouse and keyboard PS/2 bar code reader V1.40 www.allytek.com 7 www.allytek.com CHESEN CSC0101A Dual PS/2 to USB Data Converter Controller Electrical Characteristics VDD=5V, GND=0V, TA=25℃, Fosc=6MHz Parameters Symbol Operating Voltage Vdd Operating Current Iop Suspend Current Isp Input High Voltage Vih Input Low Voltage Vil Output High Voltage Voh Output Low Voltage Vol Min 4.4 Typ 5 Max 5.25 20 500 2 0.8 2.4 0.4 Unit V mA uA V V V V Conditions No load Product Matrix Part Number CSC0101A CSC0101A-S16 2004/May Memory ROM Size RAM Size 6K Bytes 256 Bytes 6K Bytes 256 Bytes I/Os Package Type Operating Range 6 6 Dice SOP-16 Commercial Commercial V1.40 www.allytek.com 8 CHESEN www.allytek.com CSC0101A Dual PS/2 to USB Data Converter Controller Package Outline 2004/May V1.40 www.allytek.com 9 CHESEN www.allytek.com CSC0101A Dual PS/2 to USB Data Converter Controller Bonding Diagram 2004/May V1.40 www.allytek.com 10 www.allytek.com CHESEN CSC0101A Dual PS/2 to USB Data Converter Controller Coordination: Orientation: (0, 0) Chip size: 1867.45 um x 1726.25 um Lower left: (0, 0) Top right: (1867.45, 1726.25) Min bonding pitch: 92 um IC substrate should be connected to GND Pad No 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 2004/May Pad Name P31 P32 P33 P34 RSTB_T P01 X 42 42 42 42 42 42 42 42 42 42 42 42 319.125 434.725 526.725 618.725 710.725 818.325 925.925 1017.925 1109.925 1217.525 1325.125 1432.725 Y 1407.125 1302.675 1208.475 1114.25 1020.025 925.825 831.6 737.4 643.175 548.95 439.15 319.125 42 42 42 42 42 42 42 42 42 42 42 42 V1.40 Pad No 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 Pad Name M1 VCC OSC2 OSC1 SMT_SEL GND M0 USB3V3 IVCC D+ D- X 1548.325 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1825.45 1548.325 1447.85 1355.625 1200.6 1108.375 1016.125 923.9 831.675 739.45 533.4 319.125 www.allytek.com Y 42 319.125 428.35 524.95 621.575 718.2 814.8 911.425 1008.025 1104.65 1201.275 1297.875 1407.125 1684.25 1684.25 1684.25 1684.25 1684.25 1684.25 1684.25 1684.25 1684.25 1684.25 1684.25 11
