DEVBOARD4 - USB

Product DEVBOARD4

PIC18F67J50 TQFP64, USB & SD Card connectors

The DEVBOARD4 is a proto-typing board used to quickly and easily evaluate the USB 1.1 and 2.0 bus.

It provides easy access to 28 IOs pins on the CPU. In order to accommodate all of the microcontroller’s on-chip peripherals the board comes with a very large proto-typing area, 474plated-through holes and many CMS footprints. So the user can decide which peripherals to be use.

28 IO Ports
Low Speed (1.5Mb/s) & Full Speed (12Mb/s)
128KBytes Flash & 3904Bytes SRAM
16MHz Oscillator & PLL 48Mhz
Internal 31KHz oscillator
10 bits Analog to Digital Convertor
5 Timers
2 Enhanced UART ( RS232, RS485, LIN1.2)
8x8 Single Cycle Hardware Multiplier
Internal Watchdog and power features
SD card connector
Footprint for SPI FLASH Memory up to 128Mbits ( M25P10 to M25P128 )
Header for alphanumeric LCD screen ( LCD NOT INCLUD )
Header for ICD2/ICD3 and ICSP© (debugging/programming flash parts).
Header RS232C ( Communication / Bootloader / debbug )
474 plated-through holes proto-typing area.
CMS Footprints ( 0805, SOT23, SO16 )
Regulated power +3.3V / 800mA
RESET switch

The DEVBOARD4 is a high quality EPOXY RoHS prototype board, complete with a solder mask on both sides of the board, with a high-contrast silk-screen labeling component positions. Board size is a compact 118 x 76mm.

WARNING: On the V1.0 PCB board, the J4 connector is NOT usable. A regrettable error was on the schematic – Sorry, it will repair for the next PCB bench. All functionalities are available with J3 – ICSP connector. You may even use the ICD2 tool from Microchip if you do a little connectors adapter.
