Microchip Technology ATF15XXDK3-SAA44

Overview

ATF15XXDK3-SAA44 from Atmel is a 20-lead TSSOP socket adapter board designed for in-system programming (ISP) of AT18F-series FPGA configuration memories (AT18F010-30XU, AT18F002-30XU, AT18F040-30XU, AT18F080-30XU) using the ATF15xx-DK3 base board and JTAG ISP cable. It provides mechanical and electrical interface compatibility between the 20-pin TSSOP-packaged configurators and the development kit's JTAG, VCCIO (3.3 V), VCCINT (3.3 V), and GND signal paths.

For engineers reviewing the ATF15XXDK3-SAA44 datasheet, ATF15XXDK3-SAA44 pinout, ATF15XXDK3-SAA44 application, or ATF15XXDK3-SAA44 equivalent, this adapter enables rapid prototyping and evaluation of Atmel AT18F configurators in FPGA-based systems requiring verified configuration memory programming, voltage-controlled ISP validation, and JTAG daisy-chain scalability.

Technical Context

The ATF15XXDK3-SAA44 serves exclusively as a passive mechanical and routing interface - it contains no active circuitry, logic, or regulation. Its design maps all 20 pins of the AT18F-series TSSOP devices to corresponding JTAG, power, and I/O header connections on the ATF15xx-DK3 base board via JP1 and JP2 male headers.

It supports only the AT18F family's standardized 20-lead TSSOP package (e.g., AT18F010-30XU), requires both VCCIO and VCCINT set to 3.3 V during programming, and relies entirely on the base board for voltage regulation, clocking, and JTAG signal buffering - none of which are implemented on the adapter itself.

FAQ

What is the primary function of the ATF15XXDK3-SAA44?

The ATF15XXDK3-SAA44 is a passive 20-lead TSSOP socket adapter board that physically and electrically interfaces AT18F-series FPGA configuration memories (e.g., AT18F010-30XU) with the ATF15xx-DK3 base board. It routes JTAG signals, VCCIO, VCCINT, and GND without modification or regulation - its sole purpose is mechanical compatibility and signal pass-through for ISP programming and evaluation.

Which devices does the ATF15XXDK3-SAA44 support?

The ATF15XXDK3-SAA44 supports only the AT18F-series FPGA configuration memories in 20-lead TSSOP packaging: AT18F010-30XU, AT18F002-30XU, AT18F040-30XU, and AT18F080-30XU. It is not compatible with CPLDs, microcontrollers, or any other device family - its pinout and layout are strictly defined for this specific AT18F variant group.

Does the ATF15XXDK3-SAA44 include voltage regulation or logic circuitry?

No. The ATF15XXDK3-SAA44 contains no active components, regulators, level shifters, or logic. It is a purely passive interposer board. All power conditioning (VCCIO/VCCINT regulation), JTAG signal buffering, and clock generation are handled by the ATF15xx-DK3 base board - the ATF15XXDK3-SAA44 performs only pin-to-pin signal routing and mechanical socketing.

How is the ATF15XXDK3-SAA44 mounted to the ATF15xx-DK3 base board?

The ATF15XXDK3-SAA44 mounts via two bottom-side male headers - JP1 and JP2 - which mate directly to female headers JP4 and JP3 on the ATF15xx-DK3 base board. This connection delivers JTAG, power, and ground signals from the base board to the TSSOP socket. No soldering or additional hardware is required for standard operation.

Can the ATF15XXDK3-SAA44 be used for production programming?

No. The ATF15XXDK3-SAA44 is intended solely for development, prototyping, and lab-based evaluation. Atmel explicitly recommends industrial gang programmers (e.g., BP, Hi-Lo, Data I/O) or factory programming for production volumes. The ATF15XXDK3-SAA44 lacks the reliability, throughput, and process control required for manufacturing-line deployment.
