1. MMusbVNC1L User s Manual REV 1 0 Introduction Thank You for buying our minimodule MMusbVNC1L MMusbVNC1L is low cost integrated Host USB module It is based on FTDI s VNC1L 1A device Module allow communicate to MCU PLD or FPGAvia one of the three interfaces UART SPI and parallel FIFO Interface selecting is possible by two shorts SEL1 and SEL2 VNC1L 1A chip chich is a hart of our module transparently handles the FAT File structure and is fully compliant with USB 2 0 specification Our module is delivered with VDAP firmware installed which allow to communication with so popularly USB Flash drives MMusbVNC1L is made in two layer printed circuit bard technology It Has 64k byte program Flash ROM memory and 4k byte SRAM data memory All signals are driver via 24 pin 1 1inch wide footprint Integral power control allow to power external devices Choosing our minimodule is the first step for projects which should be done in the short time MMusbVNC1L could be used as part of prototype eliminating necessity of designing circuit board and final circuit in which module is fitted like sandwich shape We wish you were successful at designing and using new devices Features MMusbVNC1L e Low dimension USB type A socjet and second USB port available by module pins e Fully compliant with USB 2 0 specifi cation USB full speed 12 Mbps and low speed 1 5 Mbps USB host and slave device compatible e Single 52. MMusbVNC1L is delivered with VDAP firmware installed Full firmware s documentation is able on product webside Below is placed sample connection schematic to minimodule MMusb232 which allow to install firmware by PC USB ONAQSnIA IA wos xodomd nam TI MMusb232 To enable the bootloader the PG pin must be driven low and the MMusbVNC1L must then be reset by driving the RS pin low then high Run mode can be enabled by driving the PROG pin high and then resetting the VNC1L by driving the RESET pin low then high Note that for the bootloader to be active PG pin must be driven low before powering the VNC1L If the PG pin is not driven low the VNC1L will power up in run mode with the bootloader inactive Vinculum Firmware User Manual ANVNC1L 01 Vinculum VNC1L Bootloader PYM tion Second USB port connection example Ferrite Bead JN AQSDIATAT e ES wos xodomd mmm GND Technical Support If You hale a problem with MMusbVNC1L please contact us at support propox com AROK Many ideas one solution Schematic PAPS pUJ Iywsn dnd ti spo W3GY3H did Nid FC INY 2 awop md muop qnd 1451 dn gnd umop pmd xi wu wees e ent um ur ur xi P qm ern leeran sa E a STT JXvN3 5O3Nd NILX oUm peas pop zgh peuraa me quu Pay aq o soup ap atop edog pop penam ap go uas m ud snp uo 1csserdn gmd pp e zug
