Frequently Asked Questions
Q1: What does the “-6I” suffix signify in the W9825G6JB-6I part number?
A: “-6” indicates a maximum 166MHz operating frequency at CL3; “I” represents industrial grade supporting -40°C ~ +85°C, while commercial version W9825G6JB-6 operates at 0°C ~ +70°C.
Q2: What is the primary difference between W9825G6JB and W9825G6KH?
A: W9825G6JB is 54-ball TFBGA package with smaller PCB size and superior signal integrity. W9825G6KH comes in 54-pin TSOP II package, suitable for traditional through-hole & double-sided PCB designs.
Q3: Is the W9825G6JB-6I compatible with standard 3.3V logic levels?
A: Yes. It runs on 3.0V~3.6V power rail with LVTTL I/O. It can directly work with most 3.3V MCU/FPGA like EP4CE10F17C8N without level shifters.
Q4: Does W9825G6JB-6I support automatic refresh operations?
A: Yes. It supports Auto-Refresh and Self-Refresh, requiring 8192 refresh cycles every 64ms to retain stored data.
Q5: Can W9825G6JB-6I be pin-to-pin replaced with W9825G6JB-7I?
A: Partially compatible. W9825G6JB-7I max frequency is 143MHz, slower than 166MHz of -6I. Replacement is allowed only if your system clock ≤143MHz.
Q6: What are typical application scenarios for W9825G6JB-6I compared with W9864G6JB?
A: W9825G6JB-6I is 256Mbit SDRAM for low-to-medium buffering. W9864G6JB is 64Mbit, chosen for cost-sensitive lightweight embedded devices with smaller memory demand.
Q7: Is the industrial-grade W9825G6JB-6I interchangeable with commercial W9825G6JB-6?
A: Electrically identical at normal temperature. But W9825G6JB-6 cannot be used in outdoor or freezing environments, so cross-replacement is not recommended for industrial equipment.
Q8: What’s the data width of W9825G6JB series, any alternative 32-bit SDRAM model?
A: W9825G6JB series is 16-bit width. If you need 32-bit bus design, you can select Winbond W9882G6JH as a common alternative solution.
