MachXO Control
Complete Development Platform for System Control Applications
L A T T I C E
Temperature and current monitoring, power supply
sequencing, fan control, and fault logging are typical board
control functions used in system control designs. The
MachXO™ Control Development Kit provides designers
with a platform for rapidly prototyping these functions.
Control SoC Design Simplifies Prototyping
Using the preloaded system-on-chip (SoC) design provided
with the development kit, you can now test within minutes
board control functions including fan-speed based on
temperature monitoring, LCD control, comprehensive power
supply monitoring and reset distribution in conjunction with
the Power Manager II POWR1014A and 8-bit LatticeMico8™
microcontroller.
The board can be controlled with switches and a menu-
driven interface via a Windows or Linux terminal program
over an RS-232/USB link.
PC Board Control and Power Management
The LatticeMico8 platform provides board management
functions for temperature sensing, fan and LCD control, and
monitoring of the Power Manager II POWR1014A I
face. It integrates Lattice reference designs for SRAM and SPI
Flash memory control, pulse-width modulation (PWM) fan
control, LCD control, and a Power Manager II POWR1014A
communication interface. All peripherals communicate
across a WISHBONE-compatible bus.
Users can interact with the LatticeMico8 plat form through
a menu-driven terminal program running on a PC host.
Switches and jumpers can be adjusted to emulate reset,
sleep, and supply interruptions.
