Renesas / Dialog AT25PE20 Series Serial Flash Memory
Renesas / Dialog AT25PE20 Series Serial Flash Memory is a 2-Mbit DataFlash-L, 1.65V minimum, and serial-interface sequential access page erase memory. This AT25PE20 series memory device features 2,162,688 bits of memory organized as 1,024 pages of 256 bytes (default) or 264 bytes (customer option) each. The AT25PE20 series operates from a single 1.65V to 3.6V power supply for the erase, program, and read operations. The AT25PE20 flash memory contains one SRAM buffer of 256 or 264 bytes in addition to the main memory. This buffer can also be used as additional system scratch memory. The AT25PE20 series is ideally suited for a wide variety of digital voice, image, program code, and data storage applications.
