MC9S08PL4 schematics review

[shai_b]

Hello Team,

My Customer has a plan to use MC9S08PL4 and they want to review their schematics and get your recommendations for the mass-production stage, can I open a private ticket to be able to share the full schematics?

besides that, below you can find part of the drawing 

Can you please confirm that Pin 1,2,3,4 are for flashing the firmware? thanks in advance

Regards,

Shai

Hi

yes, in order to program the device you need the PTA4 (BKGD), PTA5 (Reset) VDD and VSS.

So yes the pins are ok.

If you want you can send me the schematic directly to me

In some time and depending the application maybe you will need to add an external pull up on the BKGD pin.

Regards

Dear Vicente Gomez,

Please find attached, customer schematics for review (you find below his requirements)

BTW, I have suggested him to add a capacitor of 0.1uF on the RESET pin and VSS(GND)

Second thing, there is any way to flash the device using the UART(RX/TX) pins?

Please advise back how I can share with you the schematics, thanks in advance

BTW, you can feel free to send me a mail at shai.b@telsys.co.il 

Best Regards.
