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
