NEW! Improved GA144-1.20 Evaluation Kits EVB002

With two GA144 chips, this board provides you with versatile prototyping capability. It supports several power options and has three USB interfaces behaving as asynchronous serial communications ports at speeds up to 960 Kbits/second each. Chip 0 has external SRAM and SPI flash; the new 16 MB flash is pre-programmed with polyFORTH and, when selected with jumpers, polyFORTH comes up ready to communicate with a serial ASCII terminal emulator on USB port B. USB port A may be used to program chip 0 using our arrayForth 3 IDE. Chip 1 has minimal I/O connections: SERDES and optional 2-wire synchronous to chip 0; optional USB port C for separate IDE use; and configurable reset pin. A reset/watchdog chip has been added for optional convenience, and the line interface circuitry for the Software Defined 10baseT Ethenet NIC has been added to the basic board. Export classification is the same as for the chips. Protected by patents.

End of Life Availability Policy

Most users of electronic parts have been "burned" badly at least once when the manufacturer of a critical part arbitrarily withdrew it. Our company's policy is that any product we take to production and offer for sale will continue to be available to our customers as long as it is technically and financially feasible, especially when that product has been superseded by a new one. It is the nature of the semiconductor business that the cost of doing so will increase over time; for example, in order to make more of an old chip, it may be necessary to build a large number of them, and periodically to make new masks. In such cases our customers will be part of the decision making process; while we may not be able to justify the necessary commitment of our own resources in such a case, we will not arbitrarily withdraw an old chip from our offerings unless our customers for the old chip are themselves unable to commit the necessary resources.

Alternatives to PayPal

Bitcoin Accepted Here

If you do not wish to use PayPal, please send purchase order or request to identifying the products and quantities desired, name and company, shipping address, and if outside the US a contact phone number and any relevant tax identification such as VAT numbers to facilitate customs processing. An invoice will be returned by e-mail. Payment is accepted by check, money order, or direct bank transfer.

If you wish to pay in Bitcoin, please say so clearly in your e-mail; in this case the invoice sent you will include a payment link from Coinbase set to remit our standard dollar amount equivalents at current market prices.

Our default shipping method is US Postal Service Priority Mail to simplify ordering and minimize your costs. Within the US we use small boxes when practical; outside the US we must use medium boxes so that tracking is possible. There may be substantial time delays in delivery to certain countries: For example, South Africa, Russia and most European countries have taken just less than one month, while Germany is more than one month and counting. If you wish us to use Federal Express, order your products using the default shipping but request Federal Express either in special instructions as part of your order, or by immediate e-mail. In this case we will invoice you via PayPal for the additional cost before shipment is made.
