Memory IC Procurement Notes

Verify the specific suffix 'EFIRR' against the official manufacturer datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the design accommodates the 1.65 V to 2 V supply voltage constraints. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly to prevent damage during soldering processes.

Memory IC Selection Notes

Select this component when a 1 Gbit density is required alongside strict low-voltage operation between 1.65 V and 2 V. It is suitable for designs needing high-speed serial access up to 166 MHz. Compare against the GD55B series if a higher 2.7 V to 3.6 V supply voltage is available, or the GD55LX series if octal DTR interface support is necessary.
