ISPnano-MUX4-KIT - 4 channel multiplexed ISP Programming System - KIT


The "ISPnano-MUX4" is a state-of-the-art production In-System Programming (ISP) system designed to sequentially program up to 4 target devices. The system is aimed at production programming of PCB panels where each PCB has a programmable IC on it.

The programmer uses a single integrated 'ISPnano programmer' which is then multiplexed sequentially to each UUT on the PCB panel. This allows the system to sequentially program up to 4 individual UUTs, one after the other.

The sequential multiplexing approach supports programming of only one UUT at a time which means that the programming time for a panel of PCBs which will be significantly longer than if an individual programmer was used for each channel. However, for many programming applications, the programming time is very short anyway or is not the most important factor in the system, so this multiplexed approach would work very well.

The programming signals for each programming channel are multiplexed using high-quality analogue switches to each UUT in turn. The power signals (TVCC, VPP and EXT-VCC) are all individually switched to each UUT using relays. This approach allows the power to each UUT to be individually controlled and measured and means that only a single UUT is then powered on at any point in time making it possible to detect short circuits and other faults for an individual UUT.

The ISPnano-MUX4 programmer is capable of operating in 'Standalone Mode' where any one of 64 independent 'Programming Projects' can be executed via a remote command.  The programmer also features a 4-wire TTL Remote Control interface making it ideal for interfacing to any ATE or In-Circuit Tester (ICT). A special 'Start Signal' can be used to detect when a Test Fixture lid has been closed and thereby automatically start a programming operation.

Main Features

  • Available as 2 / 4 or 8 channel multiplexed programming system
  • Supports sequential programming of 2 / 4 or 8 UUTs (depending on programmer model)
  • A single 'ISPnano Series 3' programmer is multiplexed sequentially to up to 8 individual Target Boards (UUTs)
  • All programming signals are multiplexed to each UUT using high-quality analogue switches
  • All programming signals are fully ESD and over-voltage protected
  • All passive / power signals (Target VCC, Target Vpp and EXT-VCC power signals) are switched via individual high-quality relays to each UUT
  • Power is always switched off to the target UUT before switching to the next UUT thus providing very long relay contact life
  • Each programming channel features its own interchangeable 'I/O Connector Module' with relays and any custom target connectors
  • Status indicators include - current channel being programmed and PASS / BUSY / FAIL
  • Controllable via a PC using the Equinox EDS, ConsoleEDS or ISP-PRO software utilities
  • Channel multiplexer control can be controlled either via the PC or a remote system

Programmer – Target I/O Signals

The ISPnano features the following programmable signal lines which interface the programmer and the Target IC(s) to be programmed on the Target System:
• 5 x Programmable Input / Output lines
• 1 x Programmable Output only line
1 x Dedicated I2C (Two Wire Interface) port
1 x Dedicated RESET pin with user-defineable push-pull control
1 x Programmable 32.771 kHz Oscillator Output for Oscillator Calibration on Programmer I/O1 pin

Programmer Power Supplies

The ISPnano features the following on-board power supplies:
1 x Programmable Target Vcc Supply: 1.2 - 5.0V @ 300mA
• 1 x Programmable Target Vpp Supply: 5.8 - 13.5V @ 100mA
• 1 x External Vcc Voltage Supply (1.2V - 24.0V) switched to Target System

Power Supply features:
• Wide power supply input voltage range: 9.0V to 24.0V
• Short-circuit protected outputs
• Fast rise-time with enhanced current pumping capability to fast charge any capacitance on the Target System.
• Each power supply output (Vcc and Vpp) can be user-calibrated to a very accurate "spot voltage"
• Switchable Target Discharge Circuit - provides a fast discharge method for any capacitance on the Target System.
• Voltage measurement - supports measurement of Target Voltage, Line Driver Voltage and one External Voltage (1.2V - 30.0V)
• Current measurement - supports measurement of Target current on switch-on.

Host Control connectivity (Communications Ports)

• 1 x High-speed USB Port (mini-USB connector)
• 1 x RS232 Serial Ports
• 1 x RS485 IN/OUT port – supports up to 32 programmers on an RS485 network
• 4-wire TTL Remote Control Port
• Remote Keypad / Display (ideal for standalone control in a Test Fixture)

Gang ISP Programming / network programming support

Gang ISP Programming configuration is ideal for programming multiple PCB's on a 'PCB Panel'
Up to 32 programmers can be controlled from a single PC using the RS485 Bus
• Compact size and network option allows up to 32 programmers to be mounted even in small fixtures.


Standalone Programming Operation (no PC)

The ISPnano programmer is capable of operating in ‘Standalone Mode’ i.e. without PC Control. In this mode a single 'Programming Project' or a set of 'Chained Projects' can be triggered using an external event. The programmer can be triggered to start a programming sequence using any of the following methods:

[START] button on front panel
4-wire TTL Remote control Port (Ideal for ATE Remote Control)
Target 'Load Sensing' Detection
• Test Fixture 'Lid Switch Sensing' (closes to start programming)
Remote Keypad / Display mounted on the top of the Test Fixture
