TUMPA serial 1.8V support?
vancv
Hello I need 1.8V serial for my application. Does TUMPA supports it? (Maybe over JTAG header)?
Thanks

No. JTAG signals are 5V to 1.8V tolerant. But TUMPA uses a 3v to 5.5v multichannel RS232 Line driver/receiver for serial communication. Consequently 1.8V serial is not supported AFAIK.
