#105535 - 5 - 3.3V conversion |
Hi, I would like to interface 89S8252(12MHz, 5V) with a FPGA(3.3V). Can I use the following for Sclk, MOSI, and MISO? Or is there any other good method(s) available? I can't use 3.3version of s8252, since I have already bought this chip.
The gate is 74HC09(sorry it is LS in the schematic)open collector AND, pull up is 1kOhm. The Max Sclk frequency would be 100kHz. Cheers, Vignesh |
