ContributorCyclone10 do not support AS config scheme when Configurationn Voltage Standard=2.5V ?
Hi there,
we are using 10CL055YU484C8G, ALL 8 bank VCCIO=2.5V, VCCA=2.5V, VCC_core=1.2V
We planned to use AS config scheme with standard POR delay, however, From latest Cyclone10 LP handbook, section 6.3.1 Table44(as below), there is no corresponding MSEL code for 2.5V Configuration Voltage Standard. Only 3.3V and 3.0V are listed.
1.Does this mean C10 LP devide does not support AS config scheme when VCCIO=2.5V? That sounds very weird......and we do notice that in previous version of cyclone handbook that 2.5V is listed here. Please help confim. Thanks.
2.If we need to use 4M-Bytes third party flash IC for AS, is it feasible to choose a flash IC whose VCC=3.3V? As C10's VCCIO=2.5V, it concerns that 3.3V logic may damage FPGA, or at least they may not recognizable (voltage-level-incompatible) with each other . Maybe should I insert a 2.5V-to-3.3V voltage level transfer interfaceing IC between C10 FPGA and Flash? Also, hope you could recommend some third party part numbers. Thanks.
Hi xytech,
Please refer to KDB below. I hope it will help you.
Thanks.
