Alliance Memory now offering Micron parallel and serial NOR flash products

09 February 2021

Alliance Memory is now an authorized reseller for additional legacy NOR flash devices from Micron Technology. In addition to the previously announced M29F 5 V parallel NOR flash devices, Alliance is now reselling select offerings from Micron’s M45PE serial NOR flash, the N25Q serial NOR flash, the J3 parallel NOR flash and the P30/P33 parallel NOR flash families, all of which Micron previously discontinued with product change notification #32163 (last time buy: March 2018). Micron is continuing to produce these devices for Alliance Memory and intends to only supply Alliance Memory for any new orders placed through mid-2021.

The Micron-made legacy NOR flash parts highlighted in the following sections are now available directly from Alliance Memory:

M45PE 3 V serial NOR flash
Micron’s M45PE series products are 3 V page erasable serial NOR flash memory devices accessed by the SPI-compatible bus. The memory can be written or programmed 1 byte to 256 bytes at a time using the PAGE WRITE or PAGE PROGRAM commands. The PAGE WRITE command consists of an integrated PAGE ERASE cycle followed by a PAGE PROGRAM cycle.

N25Q 1.8 V and 3 V serial NOR flash
Micron’s N25Q series consists of high-performance multiple input/output serial flash memory devices manufactured on 65 nm NOR technology. It features execute-in-place (XIP) functionality, advanced write protection mechanisms and a high-speed SPI-compatible bus interface. The innovative, high-performance, Source: Alliance MemorySource: Alliance Memorydual- and quad-input/output instructions enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.

J3 and P30/P33 parallel NOR flash
Micron’s J3, P30 and P33 series consists of high-performance single-bit cell (SBC) and multi-level cell (MLC) parallel flash memory devices manufactured on 65 nm NOR technology. They feature advanced write protection mechanisms, x8 and x16 bus widths, and are common flash interface (CFI) compatible.
