HM-6617
March 1997
2K x 8 CMOS PROM
Description
The HM-6617 is a 16,384 bit fuse link CMOS PROM in a 2K
word by 8-bit/word format with “Three-State” outputs. This
PROM is available in the standard 0.600 inch wide 24 pin
SBDIP, the 0.300 inch wide slimline SBDIP, and the JEDEC
standard 32 pad CLCC.
The HM-6617 utilizes a synchronous design technique. This
includes on-chip address latches and a separate output
enable control which makes this device ideal for applications
utilizing recent generation microprocessors. This design
technique, combined with the Intersil advanced self-aligned
silicon gate CMOS process technology offers ultra-low
standby current. Low ICCSB is ideal for battery applications
or other systems with low power requirements.
The Intersil NiCr fuse link technology is utilized on this and
other Intersil CMOS PROMs. This gives the user a PROM
with permanent, stable storage characteristics over the full
industrial and military temperature voltage ranges. NiCr fuse
technology combined with the low power characteristics of
CMOS provides an excellent alternative to standard bipolar
PROMs or NMOS EPROMs.
All bits are manufactured storing a logical “0” and can be
selectively programmed for a logical “1” at any bit location.

HM-6617
Background Information Programming
Algorithm
The HM-6617 CMOS PROM is manufactured with all bits
containing a logical zero (output low). Any bit can be pro-
grammed selectively to a logical one (output high) state by
following the procedure shown below. To accomplish this, a
programmer can be built that meets the specifications
shown, or any of the approved commercial programmers can
be used.
Programming Sequence Of Events
1. Apply a voltage of V
CC1
to V
CC
of the PROM.
2. Read all fuse locations to verify that the PROM is blank
(output low).
3. Place the PROM in the initial state for programming: E =
V
IH
, P = V
IH
, G = V
IL
.
4. Apply the correct binary address for the word to be pro-
grammed. No inputs should be left open circuit.
5. After a delay of tD, apply voltage of V
IL
to E (pin 18) to ac-
cess the addressed word.
6. The address may be held through the cycle, but must be
held valid at least for a time equal to tD after the falling
edge of E. None of the inputs should be allowed to float
to an invalid logic level.
7. After a delay of tD, disable the outputs by applying a volt-
age of V
IH
to G (pin 20).
8. After a delay of tD, apply voltage of V
IL
to P (pin 21).
9. After delay of tD, raise V
CC
(pin 24) to VCCPROG with a
rise time of tR. All outputs at V
IH
should track V
CC
with
V
CC
-2.0V to V
CC
+0.3V. This could be accomplished by
pulling outputs at V
IH
to V
CC
through pull-up resistors of
value Rn.
10. After a delay of tD, pull the output which corresponds to
the bit to be programmed to V
IL
. Only one bit should be
programmed at a time.
11. After a delay of tPW, allow the output to be pulled to V
IH
through pull-up resistor Rn.
12. After a delay of tD, reduce V
CC
(pin 24) to V
CC1
with a fall
time of tF. All outputs at V
IH
should track V
CC
with V
CC
2.0V
to V
CC
+0.3V. This could be accomplished by pulling out-
puts at V
IH
to V
CC
through pull-up resistors of value Rn.
13. Apply a voltage of V
IH
to P (pin 21).
14. After a delay of tD, apply a voltage of V
IL
to G (pin 20).
15. After a delay of tD, examine the outputs for correct data. If
any location verifies incorrectly, repeat steps 4 through 14
(attempting to program only those bits in the word which
verified incorrectly) up to a maximum of eight attempts for
a given word. If a word does not program within eight at-
tempts, it should be considered a programming reject.
16. Repeat steps 3 through 15 for all other bits to be pro-
grammed in the PROM.
Post-Programming Verification
17. Place the PROM in the post-programming verification
mode: E = V
IH
, G = V
IL
, P = V
IH
, V
CC
(pin 24) = V
CC1
.
18. Apply the correct binary address of the word to be veri-
fied to the PROM.
19. After a delay of tD, apply a voltage of V
IL
to E (pin 18).
20. After a delay of tD, examine the outputs for correct data.
If any location fails to verify correctly, the PROM should
be considered a programming reject.
21. Repeat steps 17 through 20 for all possible programming
locations
Post-Programming Read
22. Apply a voltage of V
CC2
= 4.0V to V
CC
(pin 24).
23. After a delay of tD, apply a voltage of V
IH
to E (pin 18).
24. Apply the correct binary address of the word to be read.
25. After a delay of TAVEL, apply a voltage of V
IL
to E (pin
18).
26. After a delay of TELQV, examine the outputs for correct
data. If any location fails to verify correctly, the PROM
should be considered a programming reject.
27. Repeat steps 23 through 26 for all address locations.
28. Apply a voltage of V
CC2
= 6.0V to V
CC
(pin 24).
29. Repeat steps 23 through 26 for all address locations.
