Title: PSP Docking Station / RSM2257-G & WL8P153SNJ Datasheets
Post by: paul_g_787 on May 02, 2020, 08:39:24 pm

Hi.

I am attempting to fault find my recently aquired PSP slim docking station. The docking station has a remote control and unfortunately the remote is not operating the PSP.

It is a Blaze 3 in 1 PSP Video Charging Dock as shown here:

There are two ICs onboard:

The smallest is an RSM2257-G which I expect is an op-amp? I am not sure
The larger IC is a WL8P153SNJ which I expect is a programmable microcontroller used to receive the IR and send it to the PSP via serial.

I am having trouble finding the datasheets for these ICs. Does anybody have these to hand or know where I might find them?

Thank you

Attached is the least-blurry photo I could take.
