SST39VF200A-70-4C-EKE

Introduction to SST39VF200A-70-4C-EKE:
- Type: 2‑Mbit NOR Flash memory from SST, used for non-volatile code storage in embedded systems.
- Interface/organization: parallel 8-bit data bus; typically organized as 256K × 8 (or equivalent); uses standard NOR flash control signals (CE#, OE#, WE#) with address lines.
- Speed/packaging: -70 denotes 70 ns access time; -4C-EKE identifies the package type and temperature rating.
- Features: asynchronous read with program and erase operations via a standard command set (READ, PROGRAM, ERASE); suitable for firmware storage and boot ROMs.
- Electrical considerations: single-supply operation (voltage is device-specific—see datasheet); finite erase/write endurance and data retention characteristics.
- Datasheet: consult the SST39VF200A datasheet for exact organization, voltages, timing, endurance, erase-block size, and packaging details.

Equivalent products (2-Mbit, 70ns, 5V parallel NOR flash) from other vendors include:
- Am29F020 (AMD/Spansion)
- W29C020 (Winbond)
- MX29F020 (Macronix)
Note: exact package and revision may vary; verify with a cross-reference chart or distributor.
