Description
Electronic Component Model: A55EL
Product Category: IC Chips
The A55EL is a 256M Bit (16M x16) Synch Burst, Multi Bank SLC NOR Flash Memory. It features a single 1.8V power supply and is organized as 16Mx16. The memory architecture of the device is designed to divide its memory arrays into 256 blocks (Uniform block part)/259 blocks (Boot block part) with independent hardware protection. This block architecture provides highly flexible erase and program capability. The A55EL NOR Flash consists of sixteen banks, allowing for reading data from one bank while programming or erasing in the other bank. It has varying burst access times and initial access times depending on the operating frequency.
