GENERAL DESCRIPTION
The EN29GL256 offers a fast page access time of 25 ns with a corresponding random access time as
fast as 90 ns. It features a Write Buffer that allows a maximum of 32 words/64 bytes to be programmed
in one operation, resulting in faster effective programming time than standard programming algorithms.
This makes the device ideal for today’s embedded applications that require higher density, better
performance and lower power consumption.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
