Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS7C32098A-10TIN is determined by the following critical parameters:

Memory capacity and organization must remain constant at 2Mbit with 128K x 16 configuration to ensure functional equivalence in address and data bus requirements. The parallel interface type is mandatory for direct pin-level compatibility. Surface mount packaging in the 44-TSOP form factor is required to maintain PCB layout compatibility. Operating temperature range of -40°C to 85°C must be supported. RoHS3 compliance and MSL 3 rating ensure regulatory and handling consistency. Voltage supply range compatibility is evaluated on a case-by-case basis, with substitutes supporting the original supply voltage range or a superset thereof.

The IS62WV12816BLL-55TLI meets these substitution criteria through identical memory capacity, organization, parallel interface, 44-TSOP packaging, operating temperature range, RoHS3 compliance, and MSL 3 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the AS7C32098A-10TIN and IS62WV12816BLL-55TLI are Active product status components with full RoHS3 compliance and REACH unaffected designation. The primary differentiation between these parts is access time and write cycle time performance. The main part specifies 10 ns timing, while the substitute specifies 55 ns timing. The substitute additionally supports a lower voltage supply floor of 2.5V compared to the main part's 3V minimum. Selection between these parts depends on system timing requirements and supply voltage specifications. Both parts maintain identical memory organization, parallel interface architecture, 44-TSOP packaging, operating temperature range, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the IS62WV12816BLL-55TLI directly replace the AS7C32098A-10TIN in all applications?

A: Direct replacement is possible only in applications where the 55 ns access and write cycle time specifications are acceptable. Systems requiring 10 ns timing performance cannot use the substitute without design modification.

Q: Are the pin configurations identical between these parts?

A: Both parts use the 44-TSOP package with 0.400" (10.16mm) width. Pin compatibility is determined by the parallel interface architecture and 128K x 16 organization common to both parts. Consult device datasheets for detailed pinout verification.

Q: What is the voltage supply compatibility between these parts?

A: The main part requires 3V to 3.6V supply voltage. The substitute accepts 2.5V to 3.6V. Systems operating at 3V to 3.6V are compatible with both parts. Systems operating below 3V can only use the substitute.

Q: Do both parts have identical moisture sensitivity handling requirements?

A: Yes. Both parts carry MSL 3 rating with 168-hour floor life, requiring identical storage and handling procedures.

Q: Are there regulatory or compliance differences between these parts?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.
