ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000 & Mercury Device Configuration
ACEX 1K, APEX 20K, FLEX 10K, and Mercury devices can be configured with EPC2, EPC1, or EPC1441 devices. FLEX 6000 devices can be configured with EPC1 or EPC1441 devices. The EPC2, EPC1, or EPC1441 device stores configuration data in its EPROM array and serially clocks data out with an internal oscillator. The OE, nCS, and DCLK pins supply the control signals for the address counter and the output tri-state buffer. The configuration device sends a serial bitstream of configuration data to its DATA pin, which is routed to the DATA0 or DATA input pin on the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device. Figure 4 shows an ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device configured with a single EPC2, EPC1, or EPC1441 device. Figure 4.

FLEX 8000 Device Configuration
FLEX 8000 devices differ from ACEX 1K, APEX 20K, FLEX 10K, and FLEX 6000 devices in that they have internal oscillators that can provide a DCLK signal to the configuration device. The configuration device sends configuration data out as a serial bitstream on the DATA output pin. This data is routed into the FLEX 8000 device via the DATA0 input pin. The EPC1, EPC1441, EPC1213, EPC1064, and EPC1064V configuration devices support this type of configuration.

Power & Operation
This section describes Power-On Reset (POR) delay, error detection, and 3.3-V and 5.0-V operation of Altera configuration devices.
Power-On Reset
During initial power-up, a POR delay occurs to permit voltage levels to stabilize. When configuring an ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device with an EPC2, EPC1, or EPC1441 device, the POR delay occurs inside the configuration device, and the POR delay is a maximum of 100 ms. When configuring a FLEX 8000 device with an EPC1213, EPC1064, or EPC1064V device, the POR delay occurs inside the FLEX 8000 device, and the POR delay is typically 100 ms, with a maximum of 200 ms.
Error Detection Circuitry

Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
3.3-V or 5.0-V Operation
EPC2, EPC1, and EPC1441 devices can configure 5.0-V, 3.3-V, or 2.5-V devices. For each configuration device, an option must be set for 5.0-V or 3.3-V operation. For EPC1 and EPC1441 configuration devices, the Use Low-Voltage Configuration EPROM option in the Global Project Device Options dialog box (Assign menu) in the MAX+PLUS II software sets this parameter. (For APEX 20K and Mercury devices, the Quartus software provides a similar option.) For EPC2 devices, this option is set externally by the VCCSEL pin. In addition, the EPC2 device has an externally controlled option, set by the VPPSEL pin, to adjust the programming voltage to 5.0 V or 3.3 V. The functions of the VCCSEL and VPPSEL pins are described below.
Table 6 describes the relationship between the VCC and VPP voltage levels and the required logic level for VCCSEL and VPPSEL (i.e., high or low logic level). Table 6. VCCSEL & VPPSEL Pin Functions on the EPC2 VCC Voltage Level VPP Voltage Level VCCSEL Pin Logic VPPSEL Pin Logic (V) (V) Level Level

Programming & Configuration File Support
The Quartus and MAX+PLUS II development systems provide programming support for Altera configuration devices. The Quartus and MAX+PLUS II software automatically generates a POF to program each configuration device in a project. In a multi-device project, the software can combine the programming files for multiple ACEX, APEX, FLEX, or Mercury devices into one or more configuration devices. The software allows you to select the appropriate configuration device to most efficiently store the data for each ACEX, APEX, FLEX, and Mercury device. Moreover, when compiling for ACEX 1K, FLEX 10KA, FLEX 10KE, or Mercury devices, the MAX+PLUS II software automatically defaults to generate the EPC1 or EPC1441 POF with the programming bit set for 3.3-V operation. All Altera configuration devices are programmable using Altera programming hardware in conjunction with the Quartus or MAX+PLUS II software. In addition, many manufacturers offer programming hardware that supports other Altera configuration devices.
Altera Corporation
Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
The EPC2 configuration device can be programmed in-system through its industry-standard 4-pin JTAG interface. ISP capability in the EPC2 provides ease in prototyping and updating ACEX, APEX, FLEX, and Mercury device functionality. The EPC2 configuration device can be programmed in-system via test equipment using SVF Files, Jam STAPL Files (.jam), or Jam STAPL Byte-Code Files (.jbc), embedded processors using the Jam programming and test language, and the MAX+PLUS II software via the MasterBlaster, ByteBlasterMV, or BitBlaster download cables. When programming multiple EPC2 devices in a JTAG chain, the Quartus and MAX+PLUS II software and other programming methods employ concurrent programming to simultaneously program multiple devices and reduce programming time. EPC2 devices can be programmed and erased up to 100 times. After programming an EPC2 device in-system, ACEX, APEX, FLEX, or Mercury device configuration can be initiated by including the EPC2 JTAG configuration instruction. See Table 8 on page 21.

IEEE Std. 1149.1 (JTAG) Boundary-Scan Testing
The EPC2 provides JTAG BST circuitry that complies with the IEEE Std. 1149.1-1990 specification. JTAG boundary-scan testing can be performed before or after configuration, but not during configuration. The EPC2 device supports the JTAG instructions shown in Table 8. The ISP circuitry in EPC2 devices is compatible with tools that support the IEEE Std. 1532. The IEEE Std. 1532 is a standard developed to allow concurrent ISP between multiple PLD vendors.

SAMPLE / PRELOAD EXTEST
Description
Allows a snapshot of a signal at the device pins to be captured and examined during normal device operation, and permits an initial data pattern output at the device pins. Allows the external circuitry and board-level interconnections to be tested by forcing a test pattern at the output pins and capturing results at the input pins.
