Standby Mode and Power Saving Options
MachXO2 devices are available in three options for maximum flexibility: ZE, HC and HE devices. The ZE devices
have ultra low static and dynamic power consumption. These devices use a 1.2V core voltage that further reduces
power consumption. The HC and HE devices are designed to provide high performance. The HC devices have a
built-in voltage regulator to allow for 2.5V V
MachXO2 devices have been designed with features that allow users to meet the static and dynamic power
requirements of their applications by controlling various device subsystems such as the bandgap, power-on-reset
circuitry, I/O bank controllers, power guard, on-chip oscillator, PLLs, etc. In order to maximize power savings,
MachXO2 devices support an ultra low power Stand-by mode. While most of these features are available in all
three device types, these features are mainly intended for use with MachXO2 ZE devices to manage power con-
sumption.
In the stand-by mode the MachXO2 devices are powered on and configured. Internal logic, I/Os and memories are
switched on and remain operational, as the user logic waits for an external input. The device enters this mode
when the standby input of the standby controller is toggled or when an appropriate I
by an external master. Various subsystems in the device such as the band gap, power-on-reset circuitry etc can be
configured such that they are automatically turned “off” or go into a low power consumption state to save power
when the device enters this state.

The bandgap can be turned off in standby mode. When the Bandgap is turned off, ana-
log circuitry such as the POR, PLLs, on-chip oscillator, and referenced and differential 
I/O buffers are also turned off. Bandgap can only be turned off for 1.2V devices.
The POR can be turned off in standby mode. This monitors VCC levels. In the event of
unsafe V
off, limited power detector circuitry is still active. This option is only recommended for ap-
plications in which the power supply rails are reliable.
The on-chip oscillator has two power saving features. It may be switched off if it is not
needed in your design. It can also be turned off in Standby mode.
Similar to the on-chip oscillator, the PLL also has two power saving features. It can be
statically switched off if it is not needed in a design. It can also be turned off in Standby
mode. The PLL will wait until all output clocks from the PLL are driven low before power-
ing off.
Referenced and differential I/O buffers (used to implement standards such as HSTL,
SSTL and LVDS) consume more than ratioed single-ended I/Os such as LVCMOS and
LVTTL. The I/O bank controller allows the user to turn these I/Os off dynamically on a
per bank selection.
Each primary clock net can be dynamically disabled to save power.
Power Guard is a feature implemented in input buffers. This feature allows users to
switch off the input buffer when it is not needed. This feature can be used in both clock
and data paths. Its biggest impact is that in the standby mode it can be used to switch off
clock inputs that are distributed using general routing resources.
