| Parameter / Attribute | Specification / Value |
|---|---|
| Memory type | Volatile |
| Mounting | Surface Mount |
| Supply voltage | 4.5V ~ 5.5V |
| Memory interface | Parallel |
| Operating temperature | -40°C~85°C(TA) |
| Package | Tape & Reel (TR); Cut Tape (CT) |
| Technology | SRAM - Asynchronous |
| Access time | 10 ns |
| Memory size | 1Mbit |
| Memory format | SRAM |
| Case | 44-BSOJ (0.400\", 10.16mm Width) |
| Memory organization | 64K x 16 |
| Write cycle time - word, page | 10ns |
The 10 ns write cycle time matches the read access, so back-to-back read-write sequences run at full bus speed.
The 44-SOJ package (0.400" body width, 10.16 mm) is a surface-mount footprint common in mid-1990s through 2000s designs; verify the pad layout against your board, as SOJ has a narrower body than SOIC and the pin pitch differs.
The part is ROHS3 compliant. No production-status claim beyond the official Active designation.
