The Zapper ZP10 is a complete programmable controller circuit board,
which supports concurrent development of software, logic code and
custom hardware. The primary objective is to allow you to realise
your electronic product ideas in an efficient, practical and cost-effective
The ZP10 includes the necessary micro-controller (MCU), volatile and
non-volatile memory, programmable logic device (FPGA) and power-supply
circuitry on a compact circuit board. A key feature is the user of
standard header pins for all external signals, making it ideally
suited for quick-turn prototyping. It has been designed first and
foremost for reliable and cost-effective manufacture.
Two different ARM7 based micro-controllers from NXP and five different
Spartan 3A programmable logic devices from Xilinx can be selected, to
allow cost and performance to be tuned to the application requirements.
The FPGA logic code is automatically loaded by the micro-controller
during the boot process. The FPGA has a programmable clock oscillator
so that the frequency can be tailored to match your application and
power supply requirements.
There is a 16-bit memory bus interface and an SPI interface in between
the MCU and the FPGA, making it possible to add custom peripheral
devices into the FPGA to suit your application requirements. The memory
bus interface does consume some MCU and FPGA input/output pins, however,
care has been taken to ensure that the optimal number of MCU alternate
functions are directly accessible from external pins.
It is also possible to disable the clock or completely shut off the
power supply to the FPGA while the microcontroller continues normal
operation, in order to conserve power at times when the FPGA functionality
may not be required. SUSPEND/AWAKE functionality is also supported so
the FPGA can monitor certain input/output pins, while consuming minimal
All ethernet, USB host, USB device, RS-232, RS-485, CAN, Dallas 1-wire,
SD-card, I2C and power pins are conveniently accessible through one of the
four external headers on the left-hand side of the board. All LCD
controller pins are grouped together and made available through a header
at the right-hand side of the board. Most of the FPGA pins are accessible
through the top header and the remainder, together with the MCU input/output
pins through the bottom header. Care has been taken to keep the signal
traces as short as possible and most have been kept on a single layer,
optimizing board reliability.
There are no confusing jumpers on the Zapper ZP10. All functionality is
under program control. A reset button and some general-purpose LEDs are
provided to assist with initial program development.
The ZP10 is supplied complete with U-Boot bootloader, uClinux operating
system, all the necessary software device drivers and essential FPGA
logic code, so you can hit the ground running. Code and data images can
be fetched from a host system via TFTP (Trivial File Transfer Protocol)
with commands issued via the serial console to U-Boot. U-Boot can also
be configured to automatically boot the system via TFTP on start-up.
Support for network booting means that your code compilation and
downloading is fast and efficient.
The software development toolchain is based on GNU GCC. Many popular
Linux/Unix software packages are easily portable to uClinux, and several
are provided with the Zapper, with complete source code.
