MachXO2 Family Data Sheet
Upon power-up, the configuration SRAM is ready to be configured using the selected sysCONFIG port. Once a
configuration port is selected, it will remain active throughout that configuration cycle. The IEEE 1149.1 port can be
activated any time after power-up by sending the appropriate command through the TAP port. Optionally the de-
vice can run a CRC check upon entering the user mode. This will ensure that the device was configured correctly.
The sysCONFIG port has 10 dual-function pins which can be used as general purpose I/Os if they are not required
for configuration. See TN1204,
MachXO2 Programming and Configuration Usage Guide
for more information
about using the dual-use pins as general purpose I/Os.
Lattice design software uses proprietary compression technology to compress bit-streams for use in MachXO2
devices. Use of this technology allows Lattice to provide a lower cost solution. In the unlikely event that this technol-
ogy is unable to compress bitstreams to fit into the amount of on-chip Flash memory, there are a variety of tech-
niques that can be utilized to allow the bitstream to fit in the on-chip Flash memory. For more details, refer to
TN1204,
MachXO2 Programming and Configuration Usage
Guide.
The Test Access Port (TAP) has five dual purpose pins (TDI, TDO, TMS and TCK). These pins are dual function
pins - TDI, TDO, TMS and TCK can be used as general purpose I/O if desired. For more details, refer to TN1204,
MachXO2 Programming and Configuration Usage
Guide.
TransFR (Transparent Field Reconfiguration)
TransFR is a unique Lattice technology that allows users to update their logic in the field without interrupting sys-
tem operation using a simple push-button solution. For more details refer to TN1087,
Minimizing System Interrup-
tion During Configuration Using TransFR Technology
for details.
Security and One-Time Programmable Mode (OTP)
For applications where security is important, the lack of an external bitstream provides a solution that is inherently
more secure than SRAM-based FPGAs. This is further enhanced by device locking. MachXO2 devices contain
security bits that, when set, prevent the readback of the SRAM configuration and non-volatile Flash memory
spaces. The device can be in one of two modes:
1. Unlocked – Readback of the SRAM configuration and non-volatile Flash memory spaces is allowed.
2. Permanently Locked – The device is permanently locked.
Once set, the only way to clear the security bits is to erase the device. To further complement the security of the
device, a One Time Programmable (OTP) mode is available. Once the device is set in this mode it is not possible to
erase or re-program the Flash and SRAM OTP portions of the device. For more details, refer to TN1204,

Dual Boot
MachXO2 devices can optionally boot from two patterns, a primary bitstream and a golden bitstream. If the primary
bitstream is found to be corrupt while being downloaded into the SRAM, the device shall then automatically re-boot
from the golden bitstream. Note that the primary bitstream must reside in the on-chip Flash. The golden image
MUST reside in an external SPI Flash. For more details, refer to TN1204,
MachXO2 Programming and Configura-
tion Usage
Guide.
Soft Error Detect (SED)
The SED is a CRC check of the SRAM cells after the device is configured. This check ensures that the SRAM cells
were configured successfully. This feature is enabled by a configuration bit option. The SED can also be initiated in
user mode via an input to the fabric. The clock for the SED circuit is generated using a dedicated divider. The undi-
vided clock from the on-chip oscillator is the input to this divider. For low power applications users can switch off the
SED circuit. For more details, refer to TN1204,
MachXO2 Programming and Configuration Usage
Guide.
TraceID
Each MachXO2 device contains a unique (per device), TraceID that can be used for tracking purposes or for IP
security applications. The TraceID is 64 bits long. Eight out of 64 bits are user-programmable, the remaining 56 bits
