Hello,

I plan to propose Micron 's MT25QL replacement to customers.

MT25QL256ABA8ESF-0SIT

256Mbit Single-die

64KB sector size

16-SO (300mil) package

2.7 to 3.6V Vcc

-40 to 85℃ (Non-Automotive grade)

Available RESET#, HOLD#

I found two matching part numbers in the S25FL-S datasheet.

S25FL256SAGMFI00 or

S25FL256SAGMFI00.

suffix "G" and "H" mean

G = EHPLC, SO footprint with RESET#

H = HPLC, SO footprint with RESET#

Q1: What is the difference between EHPLC and HPLC?

Q2: Which part number should I suggest against Micron's MT25QL?

Thanks,

Naoaki Morimoto

Hi

I believe I have found an error in the Serial Flash Discoverable Parameters for the S25FL512S.   The JEDEC Sector Map Parameter Dword-2 is reported by the device and specified by the datasheet is incorrect.

The DWORD is 0x3FFFFFF4, which breaks down as follows:

• Bits 0:3 = 0x4 = Erase Type 3 supported
• Bits 4:7 = 0xF = Reserved
• Bits 8:31 = 0x3FFFFF => (0x3FFFFF  + 1) * 256 = 0x40000000 = 1024 MB, which is larger than the entire device.  

Am I interpreting this incorrectly, or is there an error here? 

I can work around this by assuming a uniform erase size across the device, so I'm not stuck, but perhaps there needs to be a datasheet update.

Thanks,

p.s. Here is a snap shot of the datasheet for reference.

Hello sir,

We are developing Electronic product for Automotive Sector.

We have developed school bus controller using S70FL01GSAGMFI011 flash memory.

We would like to verify our layout attached with this mail for the S70FL01GSAGMFI011 flash memory once from your side.

Also,I attached our schematic for your reference

We would expect a prompt support from your side.
