Soft Error Detect (SED) Support
LatticeXP2 devices have dedicated logic to perform Cyclic Redundancy Code (CRC) checks. During configuration,
the configuration data bitstream can be checked with the CRC logic block. In addition, LatticeXP2 devices can be
programmed for checking soft errors in SRAM. The SED operation can run in the background during user mode
(normal operation). In the event a soft error occurs, the device can be programmed to either reload from a known
good boot image (from internal Flash or external SPI memory) or generate an error signal.
For further information on SED support, please see TN1130,
On-Chip Oscillator
Every LatticeXP2 device has an internal CMOS oscillator that is used to derive a Master Clock (CCLK) for configu-
ration. The oscillator and CCLK run continuously and are available to user logic after configuration is complete. The
available CCLK frequencies are listed in Table 2-14. When a different CCLK frequency is selected during the
design process, the following sequence takes place:
1. Device powers up with the default CCLK frequency.
2. During configuration, users select a different CCLK frequency.
3. CCLK frequency changes to the selected frequency after clock configuration bits are received.
This internal CMOS oscillator is available to the user by routing it as an input clock to the clock tree. For further
information on the use of this oscillator for configuration or user mode, please see TN1141,
