Substitute Part Grouping Explanation

Substitution eligibility for the S80KS2564GACHB040 is determined by strict equivalence across the following critical parameters:

Memory capacity and organization (256Mbit, 16M x 16 configuration)
Interface protocol (HyperBus)
Electrical performance specifications (200 MHz operation, 35 ns timing)
Supply voltage range (1.7V ~ 2V)
Operating temperature range (-40°C ~ 105°C)
Physical package (49-FBGA 8x8 form factor)
RoHS3 compliance status

The identified substitute part S80KS2564GACHV040 maintains complete electrical and mechanical equivalence to the primary part. The difference between these part numbers reflects packaging format variation (tray packaging designation) rather than functional or performance differentiation.

Frequently Asked Questions (FAQ)

Q: Are S80KS2564GACHB040 and S80KS2564GACHV040 pin-compatible?

A: Yes. Both parts use the 49-FBGA (8x8) package with identical pinout, signal assignments, and electrical characteristics. They are directly interchangeable at the PCB level.

Q: What is the difference between these two part numbers?

A: The difference is limited to packaging format designation. Both parts contain identical PSRAM die and electrical specifications. The suffix variation reflects distribution packaging format rather than functional differentiation.

Q: Can I substitute S80KS2564GACHV040 for S80KS2564GACHB040 in existing designs?

A: Yes. The parts are functionally equivalent across all electrical parameters, timing specifications, and operating conditions. No design modifications are required.

Q: Are both parts RoHS3 compliant?

A: Yes. Both S80KS2564GACHB040 and S80KS2564GACHV040 maintain full RoHS3 compliance certification.

Q: What HyperBus interface versions are supported?

A: Both parts implement the HyperBus protocol at 200 MHz operation with 35 ns access timing, supporting standard HyperBus-compatible controller interfaces.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate identically across the full -40°C to 105°C temperature range and 1.7V to 2V supply voltage range with identical performance characteristics.
