Can someone recognise the IC from this image, or the make based on the font or naming convention used?

enter image description here

The top reads F1823 towards the end The bottom reads 18507CT. Tried looking up these numbers on Google but none of the results correlate.

This IC is inside this device. It's a water flosser that has a motor controlled by a two modes and a speed function. More pictures of the PCB here

If I search for F1823 datasheet I get this link:

http://ww1.microchip.com/downloads/en/devicedoc/40001413e.pdf

14 pins version of PIC F1823: 8/14-Pin Flash Microcontrollers with XLP Technology from MicroChip.

The last line on an IC (in this case 18507CT) is normally the batch number, which is not useful for datasheet searching.

    \$\begingroup\$ If you look in the datasheet on page 420 it should have a term (Package) that shows the type (SL or SN for SOIC, ST for SOP). I always have problems identifying them. \$\endgroup\$ Mar 19, 2020 at 9:24

    \$\begingroup\$ I just realised that even if this is the correct part I wouldn't be able to replace it directly because it has an internal flash which probably was programmed before installation in the device \$\endgroup\$ Mar 19, 2020 at 9:44

    \$\begingroup\$ Closer examination with the clues from the data sheet revealed the exact part number. It's a Microchip PIC16LF1823 -I/SL 18507CT (Batch number as indicated) \$\endgroup\$ Mar 19, 2020 at 9:58

    \$\begingroup\$ Yes the flash content could be a problem … sometimes I think the flash can be protected, not able to read it out, but even if it is unprotected, it might be a 'project' to make a circuit to get the info out and copy it to another. \$\endgroup\$ Mar 19, 2020 at 10:01

    \$\begingroup\$ At this point, I'm keeping my fingers crossed and hoping there's an external flash on the same PCB in one of those SMT components. Plan is to study the datasheet and understand pins to see if it interfaces with a flash. \$\endgroup\$ Mar 19, 2020 at 10:04
