iceFUN - iCE40-HX8K FPGA
Tutti i prezzi sono IVA inclusa
The iceFUN module is powered from USB or an external 5v supply. There are on-board 3.3v and 1.2v regulators. All PIC and FPGA I/O pins are 3.3v, do not connect these to 5v devices.
iceFUN iCE40-HX8K FPGA
3 High current 12/24v RGB drivers, 1A per channel.
4 10-bit Analogue input channels via onboard PIC.
32 red LEDs, on-board LED matrix (4*8)
4 push button inputs with pull-up resistors
1 piezo sounder for sounds or tunes.
45 FPGA I/O pins available (3.3 volt).
iCE40 HX FPGA:
7680 Logic cells
128k bits embedded RAM (32 * 4k bit blocks)
2 PLL's
An on-board PIC16LF1459 takes care of USB programming, FPGA reset and start-up and also provides 4 * 10-bit analogue channels. These are available via a serial port to the FPGA. The PIC also generates a 12MHz clock to the FPGA which may be multiplied in a PLL as required. Power is from USB or a nominal 5 volts (3.5v to absolute max. 6v)
