HYUNDAI'S 8KX8 SRAMS'S

(1 / 2)


	I HAVE DISQUALIFIED HYUNDIA'S 8KX8 SRAMS FROM P/N 137535-XXX.
HYUNDAI HAS ADMITTED TO HAVING A PROCESS PROBLEM THAT SHOWS UP AS A PATTERN
SENSITIVITY PROBLEM. AS OF TODAY THIS PROBLEM HAS ONLY SHOWN UP IN THE HARD
DRIVEN SYSTEM AND IN ESCAPE IF THE PART HAS DEGRADED. ACCORDING TO HYUNDAI,
THEIR LOW POWERED PARTS DO NOT SHOW THIS PROBLEM, BUT I HAVE INCLUDED THEM
IN THE DISQUALIFICATION. IN ORDER FOR THEM TO BE APPROVED (LOW POWER), A
SAMPLE OF 100 PIECES MUST FIRST BE BURNED-IN AT 125 DEGREE C FOR 48 HOURS
WITH A PRE/POST DEVICE TESTING DONE TO ALL PARTS. WE WILL THEN RETEST IN OUR
GAMES TO ASSURE FUNCTIONALITY.

	QUALITY SHOULD MOVE ALL HYUNDAI 8KX8 SRAM'S, P/N 137535-XXX, TO
MRB UNTIL FURTHER DISPOSITION IS DETERMINED. ALSO, WORK WITH PURCHASING
IN SETTING UP A TIME FRAME WITH HYUNDAI IN CREDITING OF FIELD FAILURES.

	PURCHASING HAS ALREADY LOCATED ANOTHER VENDOR'S PARTS, SO THESE
SHOULD BE BROUGHT IN-HOUSE AS SOON AS POSSIBLE.

	ON OTHER THING: THE HYUNDAI PART HAS NOTE FAILED IN THE AUDIO
BOARD, SO IF ENGINEERING HAS NO PROBLEMS WITH THE IDEA OF STILL USING
IT IN THE AUDIO BOARD FOR THE STUN RUNNER BUILD, I'D SAY GO AHEAD AND
USE IT.

HYUNDAI'S LOW POWER 8KX8 SRAM'S

(2 / 2)


	After testing 100 low power SRAM'S from Hyundai and running 16
	of them for 45 hours at 80`C with no failures, I am willing to
	re-instate Hyundai's low power SRAM's back into part number
	137535-XXX. The Hyundai part can be used for all boards. Also,
	these 100 pieces have been identified by a sticker that states
	"COMPONENT ENG EVALUATION SRAM". If these parts fail out in the
	field I hope that they will be return to Component Engineering
	for evaluation.

	I will issue a CER adding Hyundai's part number HY6264LP's to the
	appropriate dash number for our part number 137535-XXX. any Hyundai
	low power parts being held in MRB should be transfered back into
	inventory.

	Thanks for all the help is gratefully given to JED and MANUFACTURING
	

						THANKS
