Hi guys, I added an optional SPI EEPROM (SOIC package) to Jaluino Bee. It's also pin compatible with 23K256 SRAM, and also with a SST serial flash. So PCB would work with an extra EEPROM, SRAM and Flash.
I added a 100nF decoupling cap. /WP (Write Protect) and /HOLD (pause) are tied to 3V3, so always enabled (so no write protect, and no hold/pause) in order to save few pins. Solder jumper is here to choose the Chip-Select pin depending on the PIC being used (25K22 or 27J53) [image: spi_eeprom_sram.png] Cheers, Seb 2011/4/21 Oliver Seitz <[email protected]> > > > I perfer the RAM due to fast > > read/write speeds, high endurance.
