SRAM - Asynchronous Memory IC 4Mbit Parallel 10 ns 48-TFBGA (6x8)
1. AS7C34098A-10BINTR Substitution Conclusion
In terms of core parameters, the AS7C34098A-10BINTR is fully consistent with the original part in memory density (4Mbit), organization (256Kx16), interface (parallel), and voltage range (3V–3.6V). Its access time (10 ns) is better than that of the original part (12 ns), indicating potential for direct substitution from a performance standpoint. However, a critical difference lies in the package size: the original part uses a 48‑CABGA (9×9 mm) package, whereas the AS7C34098A-10BINTR is supplied in a 48‑MiniBGA (8×10 mm) package. This may result in differences in ball‑out and board‑footprint. Direct replacement therefore requires careful verification of PCB pad compatibility and mechanical clearance; otherwise, soldering defects or physical interference may occur.
2. IS64WV25616BLL-10BLA3 Substitution Conclusion
The IS64WV25616BLL-10BLA3 is compatible with the original part in memory configuration, interface, and timing (10 ns). Its operating voltage range (2.4V–3.6V) is wider than that of the original part (3V–3.6V), offering better adaptability and potentially lower power consumption in low‑voltage applications. Nevertheless, there is a notable difference in package size: the original part is packaged in a 48‑CABGA (9×9 mm), while the IS64WV25616BLL-10BLA3 comes in a 48‑TFBGA (6×8 mm). The significantly reduced ball matrix and overall dimensions may lead to PCB layout mismatch. Redesigning the footprint or verifying that the existing board can support the finer‑pitch BGA soldering is necessary; otherwise, direct replacement is not feasible.
