Infineon CY7C1021D-10VXIT, 1Mbit asynchronous SRAM, 64K x 16 organization, 10 ns access time, parallel interface, 4.5V to 5.5V supply, -40°C to 85°C, 44-SOJ surface mount.
| Parameter | 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.
Yes, the supply voltage range is 4.5V to 5.5V, making it directly compatible with 5V logic families and legacy 5V bus architectures.
The CY7C1021D-10ZSXI is the same 1Mbit, 10 ns asynchronous SRAM in a 44-SOJ package but supplied in tray form instead of tape and reel. Verify the shipping medium matches your assembly line before substituting.
