RT54SX16 Heavy Ion Test

Single Event Latchup

and

JTAG 1149.1

Brookhaven National Labs

April, 1999

A set of three RT54SX16 MEC devices were subjected to heavy ion tests at Brookhaven National Lab, using bromine and iodine at a variety of angles.  Ion energies and ranges are detailed for each run in the table below.  These were prototype devices, not production units.  To complete the "JTAG Fix," these units were slightly modified using a FIB.  The purpose of this test was to demonstrate no loss of functionality with high fluence (JTAG fix) and no latchup at high LETs.

Minimum (4.5, 3.0), Nominal (5.0, 3.3), and maximum (5.5, 3.6) were used for the runs to exercise the part under a variety of conditions.  For "torture tests," the voltages were elevated to as high as (5.7,4.0).  There was no evidence of single event latchup or "JTAG upset" detected.  Device serial numbers LAN1401, LAN1402, and LAN1403 were used.
