Question

Anyone using Micron N25Q00AA parts? ie 1Gbit / 128MB

I'm looking to test an External Loader, so looking for guinea pigs.

Had unsuccessfully tried to buy a couple of samples but none of the listing had any stock, or they wanted to quadruple the asking price.

I'm interested in the extended parameters from READ-ID, trying to understand how it flags multi-die part, either as a die count, or die size. These have 4x the 256Mbit (32MB) die.

Another example might be the N25Q512A that had 2x die

I've got some of the newer MT25/MT35 1Gbit and 2Gbit parts using the 512Mbit (64MB) die, so got some perspective on those. The Winbond / Macronix parts are less quirky. For large devices you want to be using an ST-LINK/V3, it's faster.

Anyhow, if you have weird parts, or find stock of some odd-ball ones to fill a production order and need a loader (ST or KEIL), drop me a message.

Found some aggressively priced S25HL512T parts (Spansion, Infineon, Cypress), so will add those into the list of supported parts.

These also have internal CRC checking, only CRC-32 in this case, but CRC-64 in the Micron case. Good for BLANK CHECK, and cheap VERIFY
