AM13E23019: Missing information regarding sector erase time

Solomiia Matiichuk

Part Number: AM13E23019

Hi, could you please provide information on flash memory characteristics for AM13E23019, especially we would like to know sector erase time (max value). Haven't been able to find this information in the datasheet.

Hello Solomiia,

Please find the temporary Flash Characteristics table below. This will be included in the next release of the datasheet.

Typical Sector Erase Time: 20ms

Typical Bank Erase Time: 22ms

Regarding maximum erase time: The worst-case erase duration depends on the prior contents of the memory (i.e., how many bits need to transition) and operating conditions (temperature, voltage, program/erase cycle count). The flash controller applies erase pulses with automatic post-verification, and will assert a failure (FAILVERIFY) if the erase cannot complete within the maximum pulse count limit enforced by hardware.

Hi, Zackary,

Thank you for the answer.

Regarding maximum erase time - we would still want to have maximum possible value in the worst case scenario.
Reason: we need the max value to configure watchdog in a way it would not reset during sector erase (as we cannot feed watchdog during that time).

Maybe you have it calculated considering worst-case conditions? Or you can provide this "maximum pulse count limit enforced by hardware" value?

Thanks.

Hi Solomila,

I am working with the design team to see if there are any estimated numbers we can provide you here. Please allow me to the end of the week to connect with the correct folks and confirm the information.

Hi Solomila,

This device uses the same flash controller as the F29H85x device. Please refer to the details in the table below for reference.
