Lead Temperature (Soldering 5 sec) +265°C
Electrostatic Discharge Sensitivity 4/ Class 2 (TBD)
Notes:
1/ Stresses at or beyond the absolute maximum ratings may cause permanent damage to the device.
Extended operation at the maximum or minimum levels may degrade performance and affect reliability.
All voltages are referenced to the module ground leads.
2/ Maximum applied voltage shall not exceed 3.80V for VDD or 5.70V for VDD2.
3/ Not tested. This value is based on a steady-state wave form analysis at worst case conditions for an
active chip current spike approximately 1.5ns wide that goes to no current approximately 2.3ns into the
cycle (at 2.70V) and an I/O current spike approximately 3.0ns wide that goes to no current approximately
7.0ns into the cycle (at 3.60V). This analysis assumes a 14ns access and 20ns standby cycle. The
steady state power for these conditions is calculated to be 2.4W for the entire module.
4/ Class as defined in MIL-STD-883, Method 3015.
5/ Operation outside the recommended operating conditions specified in Table 3 may cause degradation in
the electrical parameters as defined herein.
6/ Thermal resistance is based on all five die dissipating a total of 2.4W per module. The worst case
steady-state temperature rise from the bottom of the case to the junction of the topmost die is 18.566°C.
A maximum transient delta temperature can be added to the maximum steady state temperature rise to
establish a true maximum junction temperature rise at the sub-block level. The transient analysis of a
sub-block shows the delta case to junction temperature to be 0.225°C. Therefore, the maximum case to
junction temperature rise for 2.4W dissipated by the entire module will be 18.791°C.

Note:

1.5 Power Sequencing
The substrate of this module is connected directly to Ground. Power shall be applied to the device only in
the following sequences to prevent damage due to excessive currents.
Power-up sequence: GND, VDD and/ or VDD2, Inputs
Power-down sequence: Inputs, VDD2 and/or VDD, GND
NOTES:
1) Delay between power up or down for VDD and VDD2 can be between –10ms to +50ms.
2) The loss of the 2.5V power supply (3.3V power supply active) coupled with an external event (e.g. SEU
hit on a critical I/O circuit) may result in a shorting condition. This combined event can not exist for more
than 5 minutes (cumulative time) without reliability impact. A safety margin is included in this analysis,
contact BAE SYSTEMS if this limit has been exceeded. If there is no external event, the loss of the 2.5V
power supply alone will not result in a n y reliab ility impac t.

3.3 Electrical Performance Characteristics and Postirradiation Parameter Limits
The electrical performance characteristics specified in Table IA are guaranteed for post-irradiation to those
radiation levels specified in Table IB. Device latchup will not occur for radiation levels specified in Table IB
and operating conditions less than or equal to those specified in Table 3. The applicability of these post-
irradiation guarantees for a particular device type is as specified in section 1.2 herein.

A match between the LS and LD bits will pass control of the module to chip select; a mismatch between
the LS and LD bits overrides chip select and puts the entire module into standby mode.

3.4 Electrical Test Requirements
3.4.1 Manufacturing Electrical Tests
The manufacturing electrical test requirements shall consist of functional test patterns as defined below. All
tests shall be performed across the temperature and supply voltage range as specified in 1.4 herein. Any
single functional fail shall be cause for device rejection.
The dynamic tests specified below assure test coverage for the 512Kx40 SRAM MCM device. T he patterns
are used with device specific address descrambling and various timing conditions to insure sound device
performance. The MARCH pattern, which is 13N, covers defects or faults in the memory. Such faults are
stuck cell, open cell, lack of address decode uniqueness and adjacent cell coupling. The RCGAL pattern,
which is n(3/2), covers additional performance problems that may be missed by the MARCH pattern. With
address desc rambling, th is pattern c overs the po tential per formance pr oblems that the tr aditional N patterns
did when used witho ut address descram bling. The D ADD pat tern, or data e quals addres s patt ern, wri tes a nd
reads sequential bytes of data to and from the memory under test which are equal to the eight least
significant address signals. The purpose is to check for data word uniqueness versus byte address.
MARCH:
a. Write a background of 0’s into all cells.
b. Starting at address 0, read 0, write it to a 1, read it as a 1.
c. Increment address and repeat step b. for entire memory.
d. Starting at maximum address, read 1, write it to a 0, read it as a 0.
e. Decrement address and repeat step d. for entire memory.
RCGAL:
a. Write a background of 0’s into all cells.
b. Write 1 into address Test Bit (Test Bit starts at cell zero and is incremented through the entire memory).
c. Alternately read Test Bit and each cell on the row of the Test Bit.
d. Alternately read Test Bit and each cell on the column of the Test Bit.
e. Write Test Bit back to 0, then increment the test bit.
f. Repeat Step b - e until Test Bit has been at every cell in memory.
DADD:
a. Starting at address 0, write 0 into RAM.
b. Increment address and data word.
c. Writ e RAM.
d. Repeat steps b and c until address and data equal 255 (base 10).
e. Increment address, reset data word to 0, write RAM.
f. Increment address and data word.
g. Write RAM.

Note:
1/ Burn-in conditions as defined in Section 4.5 on sheet 32.
2/ Burn-in for 160 hours at VDD= 2.70V, VDD2=3.60V, and TA=125C calculates to an equivalent accelerated stress of 19.67
hours at VDD=3.00V, VDD2=3.75V and TA=125C. For manufacturing, time in burn-in may be performed for 19.7 -0/+2.0 hours
at accelerated conditions. This calculation is based on commercial foundry reliability data with temperature acceleration
constant Ea=0.7eV and voltage acceleration constant Beta=7.0/V. This 160-hour burn-in (or equivalent) is done 2X for the
Commercial Space "T+" modified Class K flow and 1X for the Commercial Space "T" modified Class H flow.
3/ Pre burn-in or Prototype burn-in for 24 hours at VDD= 2.70V, VDD2=3.60V, and TA=125C calculates to an equivalent
accelerated stress of 2.95 hours at VDD=3.00V, VDD2=3.75V and TA=125C. For manufacturing, time in burn-in may be
performed for 3.0 -0/+1.0 hours at accelerated conditions. This calculation is based on commercial foundry reliability data with
temperature acceleration constant Ea=0.7eV and voltage acceleration constant Beta=7.0/V. This 24-hour burn-in is done for
the Prototype flow (-xx2) or for pre burn-in on the Flight flows. No burn-in is performed on Engineering parts (-xx3).
4/ This is an optional step in the flow.
4.3 Technology Conformance Inspection (TCI) for Device Classes H (T) and K (T+)
Inspection for device classes H (T) and K (T+) shall be in accordance with MIL-PRF-38534. Inspections to
be performed shall be those specified in MIL-PRF-38534 as implemented by BAE SYSTEMS’ approved
Qualit y Managem ent (QM) plan. T he TCI requ irements f or each particu lar devic e type manufac tured to this
drawing shall be as specified in section 1.2 herein.
4.3.1 Qualification Testing Requirements are defined in Table 8 on sheet 30.

4.5 Burn-in Circuit
The applicable burn-in stresses are as specified below and are required per BAE SYSTEMS specification
MAN-STC-Q002 and section 1.2 herein.
4.5.1 Stress Methodology
For ”Dynamic” burn-in, all possible addresses are written with alternating High and Low data.
All I/O p ins spec ified in t he dynam ic burn- in pin l ists are driven throug h ind ividual series resistors (1. 6K +/-
10%). Burn-in voltages are defined using the following notation:
Pre-Burnin and Accelerated Voltage Levels:
Vin(0): 0.00 V to +0.40 V VIL= LOW level for all programmed signals
Vin(1) : +3.65 V to +4.00 V VIH = HIGH level for all programmed signals
V1: + 3.00 V (-0%/+0.100V) All VDD pins are tied to this level
V2: + 3.75 V (-0%/+0.100V) All VDD2 pins are tied to this lev el
Vsx: Float or GND All GND pins are tied to this level
Burnin Vo ltage Levels:
Vin(0): 0.00 V to +0.40 V VIL= LOW level for all programmed signals
Vin(1) : +3.50 V to +3.85 V VIH = HIGH level for all programmed signals
V1: + 2.70 V (-0%/+0.100V) All VDD pins are tied to this level
V2: + 3.60 V (-0%/+0.100V) All VDD2 pins are tied to this lev el
Vsx: Float or GND All GND pins are tied to this level
The burn-in circuit diagram is shown in Figure 9 on sheet 33.
