I've been working with the prototypes the last couple months. Nobody
has any of these boards yet except for a few very special customers.
Our production run of boards just arrived but we have the pre-shipment
testing to flesh out before we can clear any of them for shipment. I
expect we will be able to start shipping early-mid next week.
The TS-7260 is very much like the TS-7250, except much lower power.
With ethernet off and the processor still running at 200Mhz, this
board draws less than a half watt (i.e. this is fully-operational, not
"stand-by"). Also, since this board has the switching power supply on
board, voltage input can be any DC voltage in the range of 4.5 - 23V
making it ideal for battery or solar powered applications. (since you
don't need another external power supply adding extra inefficiency,
cost, and complexity to your design)
Also, since we scrapped the high static power Xilinx CPLD for a lower
power Altera CPLD with a lot more space for custom logic, we've
included a third serial port and an extra 10 pins of DIO. The boards
can be built with one of a few logic loads, one of them puts 2 more
serial UARTS (total 5: 3 off-CPU, 2 on-CPU) and the other includes
something we've dubbed the TS-XDIO port. There are more in development.
The TS-XDIO is like regular DIO port (data direction register and data
register), but includes some other cute features that can be difficult
or very inefficient to do in software. The port can read quadrature
(and IRQ on direction change for min/max quadrature counts), output
PWM or finite length pulses, and also measure frequency or pulse times
with 67nS accuracy. You can also just internally loop the PWM
generator to the pulse timer and have a free-running 14.7456Mhz
counter for high resolution timestamping. (The on-CPU debug4 timer
only runs at 983kHz)
Other improvements include a new register allowing programmatic
shutdown of power to USB, PC104, and the RS232 level converters.
Being able to shutdown power to USB is a nice feature to hard reset
USB devices that get in bad states. Also, if you are designing
peripherals on the PC104 bus, there is now a way to talk straight to
the CPU SMC bus allowing design of custom boards that operate much
faster than what PC/104 normally allows for. The PC104 clock can be
gated off as well as a further way to lower power on peripheral boards
that can handle it.
