Hello
I am trying create a test setup for M16C/62A MCU.
Need help with how to find correct socket part number from a 3rd part for this setup and how to connect emulator user interface to the socket.
I know I need a socket for 14x20x0.65 pitch. Renesas has discontinued their socket for this long time ago. Need to find 3rd party socket and how to connect user interface cable to that socket.
I am just starting in this field from technical standpoint. So my question probably is a beginners question. Any help will be greatly appreciated.
Regards
Dan
Are you wanting a socket that can be placed on the QFP pad of the device? The socket in the pic was a flip-top ZIF with a thru-hole bottom pattern.
Have you checked Yamaichi, Tokyo-Eletek (TET), or Ironwood Electronics for a compatible socket?
Hi Jim ,
Thank you for your reply.
Currently due to my inexperience, I am trying to find 'a' way to connect MCU to E8A HEW. I did further research and realized I need a test socket. Honed in on one product from Aliexpress.

Below is the one from Yamaichi before I realized I needed a test socket

If you can lmk any of these will work, it will be great.
My plan is as follows
1. Find a way to connect MCU to E8A HEW
2. Make a simple program (for example blink LED)
3. remove test socket from Emulator and connect to a breadboard
4. Power breadboard using USB (will have to lookup USB-power-PCB solution for breadboard)
5. Mount LED and resistor to breadboard
6. Ensure MCU functions (Golden part MCU and Test MCU)
lmk if you think this is a sound plan from your knowledge and experience.
thx
Dan,
Here are schematic snippets where I connected an E8 to an M16C62 on a design. The connector J2 (for E8) was connected in parallel with J6 (used with a different debugger):
The connector I used for the E8 was TE Connectivity AMP Connectors 5103308-2.
Good luck!
Dirk
Hi Dirk,
Thank you for your response and this information.
Can you let me know what socket did you use? Was it a test socket?
Can I ask what is your motivation to use such an old part? If this is for hobby, you would be better off starting with something more modern (e.g. RA, RX).
The 62A went out of production much sooner than the upward compatible 62P device, which is recommended as a drop-in compatible replacement:
You might have a try at finding the 62P RSK
The schematic for this RSK is also a good reference design for the electrical connections.
As far as debugger connector, this is a good reference for the required circuit:
Both of the sockets that you referenced appear to be the thru-hole type of mounting pattern. The Mouser option appears to match the MCU package, from the referenced datasheet:
This could be used to breadboard an appropriate development system.
The Ali-Express option appears slightly too small on the max lead-length, but it may work.
