Developers can take NetBurner's $299 PK70 Product Kit and quickly turn their designs into networked devices (see the figure). At its core is the 147-MHz ColdFire 5270 32-bit processor plus 4 Mbytes of flash, 8 Mbytes of SDRAM, an SD flash card interface, an RS-232 serial port, and a 10/100 Ethernet interface. The system accepts a single Personality Blade that has access to the processor's I2C, SPI, and GPIO, plus two additional serial ports.
The PK70 comes with the NBPKBM-100 Multifunction Analog Board, which has an eight-channel, 12-bit analog-to-digital converter, a pair of 16-bit digital-to-analog converters, and 16 GPIO lines connected to a 40-pin D connector. Additional boards are available, such as the Digital Blade, which has a Xilinx programmable logic device. Custom boards can be designed using the Prototyping Blade. The power supply can deliver 1 A at 5 V dc and 750 mA at 3.3 V dc. The PK70 comes with NetBurner's software development kit, which provides access to the real-time operating system and TCP/IP stack and services built into the PK70 (see "Getting On The Network: Fast" at www.electronicdesign.com, ED Online 10580).
