NeftyTouch^TM - Parallel Port Download Adapter

Supports operation while powered up with any voltages 1.8 V – 5.5 V

Provides reliable and low-cost method for in-system programming

Downloads data from the MAX+PLUS ® II development software

Interfaces with a standard 25-pin parallel port on PCs

Uses a 10-pin ALTERA Corporation compatible circuit board connector

Features

Represents reliable and cost effective replacement solution for the Altera Corporation ByteBlaster and ByteBlasterMV download cable.

Allows PC users to perform the following functions:

Program MAX ® 9000, MAX 7000S, and MAX 7000A devices in-system via a standard parallel port interface

Configure FLEX ® 20Kx, 10Kx, FLEX 8000, FLEX 6000 devices and future generation of the devices that requires I/O signal levels below 3.3 V

Functional Description

The NeftyTouch^TM parallel port download adapter (ordering code: NEF-A-P) is a hardware interface converter of a standard PC parallel port (LPT port) to 10 pin on-board connector.

Adapter provides electrical conversion of the signals between 5 V logic levels for the LPT port and multi-voltage signal levels used on the different EPLDs and FPGAs.

Download Modes

The NeftyTouch^TM adapter provides two download modes:

Passive serial (PS) mode—Used for configuring FLEX 10K, FLEX 8000, and FLEX 6000 devices
JTAG mode—Industry-standard Joint Test Action Group (JTAG) interface for programming or configuring FLEX 10K, MAX 9000, MAX 7000S, and MAX 7000A devices

Adapter Connections

The NeftyTouch^TM adapter has a 25-pin male header that connects to the PC parallel port directly or through the extender cable (ordering code: NEF- EXT- 25FM25), and a 10-pin female plug that connects to the circuit board. Data is downloaded from the PC’s parallel port through adapter to the circuit board.

NeftyTouch^TM adapter is not sensitive to the level of the power supply that powers-up programmable device, it can accept any voltage from 1.8V to 5.5 V.

Header & Plug Connections

The 25-pin male header connects to a parallel port with a standard parallel cable.

The 10-pin female plug connects to a 10-pin male header on the circuit board containing the target device(s).

The target circuit board must supply VCC and ground to the adapter.

VCC pin of the target board 10 pin header has to be connected to the VCC_IO of the first programmable device in the chain.

Black Color Strip on the ribbon cable defines pin 1 as a key.

Operating Conditions

The following summarize the absolute maximum ratings, recommended operating conditions, and DC operating conditions for the adapter.

V CC Supply voltage With respect to ground – 0.5 - 7.0 V

V I DC input voltage With respect to ground – 0.5 - 7.0 V

V CC Supply voltage 1.8 V – 5.5 V

I CC Operating current 50 mA
