What are the key features of SCAN16602SM?
- IEEE 1149.1 JTAG boundary-scan support enables in-system board testing without physical test probes
- 16-bit bidirectional transceiver architecture maximizes data bus bandwidth in a single BGA package
- 3.3 V logic-level operation simplifies integration with modern FPGA and DSP-based backplane designs
What is SCAN16602SM used for?
SCAN16602SM serves high-speed data bus interfaces in telecom line cards, FPGA development boards, and multi-board computing systems where built-in boundary-scan testing is required to verify solder joint integrity and interconnect continuity. Its 16-bit width and BGA packaging reduce pin count and board routing complexity on dense backplane designs. The device is also used in automated test equipment where JTAG chain access accelerates production board diagnostics.

Frequently Asked Questions
How does the JTAG boundary-scan feature in SCAN16602SM benefit high-volume PCB production testing?
SCAN16602SM's IEEE 1149.1 boundary-scan allows a test controller to shift data serially through each I/O pin via the 4-wire JTAG interface at up to several MHz clock rates, detecting open solder joints, short circuits, and misloaded components across the full 16-bit bus width without physical bed-of-nails fixtures, cutting test fixture cost by hundreds to thousands of dollars per board design.
What supply voltage does SCAN16602SM require, and how does that affect interfacing with 5 V legacy logic?
SCAN16602SM operates at 3.3 V. Connecting it directly to 5 V logic outputs risks exceeding its input voltage tolerance, so a level-shifting buffer or resistor divider is needed at each 5 V-to-3.3 V crossing. On the 3.3 V output side, many 5 V CMOS inputs accept 3.3 V high signals (V_IH ≥ 2 V), making the output direction often directly compatible without additional components.
For a 16-bit parallel bus backplane running at high data rates, what advantages does SCAN16602SM's BGA package offer over an equivalent SOIC or SSOP?
The BGA package places signal balls on a grid beneath the die, shortening the average trace length from die bond pad to PCB via by several millimeters compared to a perimeter-leaded SOIC or SSOP. This reduces parasitic inductance per pin — often by 2 nH to 5 nH — improving signal integrity and enabling faster edge rates across all 16 data lines at backplane speeds.
