APEX II Device Configuration

Configuration Scheme Overview

APEXTM II devices support the following configuration schemes:

  • Serial - To Conserve Pins
    • Passive Serial (PS)
      • Uses an external intelligent host such as a PC, an enhanced configuration (EPC) device (PDF), or a microprocessor to control the configuration process synchronously and supply the configuration data serially to the APEX II device.
    • JTAG
      • Configures APEX II devices via the IEEE Standard 1149.1 interface.
  • Parallel - For Faster Configuration
    • Fast Passive Parallel (FPP)
      • Uses an external intelligent host, such as a PC, an EPC device (PDF) or a microprocessor, to control the configuration process synchronously and supply the configuration data in a parallel manor to the APEX II device.
    • Passive Parallel Asynchronous (PPA)
      • Uses an external intelligent host, such as a PC or a microprocessor, to control the configuration process asynchronously and supply the configuration data in a parallel manor to the APEX II device.

How to Configure APEX II Devices

Frequently Asked Questions  
  1. Can I use PPS configuration schemes to configure my APEX II devices?
  2. Does the EPC16 configuration device support fast passive parallel (8-bit parallel) configuration for a single FLEX®, ACEX®, APEX, or APEX II device?
  3. What is the ByteBlaster™ II download cable?
