8. Configuring Mercury,APEX 20K (2.5 V), ACEX 1K &FLEX 10K DevicesCF51006-2.1IntroductionMercury TM , APEX TM 20K (2.5 V), ACEX ® 1K, and FLEX ® 10K devices canbe configured using one of four configuration schemes. All configurationschemes use either a microprocessor or configuration device.1 This section covers how to configure Mercury, APEX 20K (2.5 V),ACEX 1K and FLEX 10K devices. APEX 20K (non-E and non-C)devices use a 2.5-V voltage supply for V CCINT , while APEX 20KEand APEX 20KC devices use a 1.8-V voltage supply for V CCINT .If your target FPGA is an APEX 20K device which uses a 1.8-VV CCINT ,. For more information, refer to Configuring APEX 20KE& APEX 20KC Devices in the Configuration Handbook.Mercury, APEX 20K (2.5 V), ACEX 1K, and FLEX 10K devices can beconfigured using the passive serial (PS), passive parallel synchronous(PPS), passive parallel asynchronous (PPA), and Joint Test Action Group(JTAG) configuration schemes. The configuration scheme used is selectedby driving the Mercury, APEX 20K (2.5 V), ACEX 1K, or FLEX 10K deviceMSEL1 and MSEL0 pins either high or low as shown in Table 8–1. If yourapplication only requires a single configuration mode, the MSEL pins canbe connected to V CC (V CCIO of the I/O bank where the MSEL pin resides)or to ground. If your application requires more than one configurationmode, you can switch the MSEL pins after the FPGA is configuredAltera Corporation 8–1August 2005
