概述

Description

SST39VF200A-70-4C-EKE is a 2-Mbit parallel NOR Flash memory from SST’s SuperFlash family. Key points:
- Capacity and bus: 2 Mbit (256 KB), 8-bit data bus.
- Timing and supply: 70 ns access time; typical 5V operation.
- Interface: 32-pin device with A0–A18, DQ0–DQ7, CE, OE, WE control signals.
- Operations: Read, Program (byte/word), and Erase (sector/block and chip). Uses standard NOR flash command set; page/program operations typically up to 256 bytes.
- Endurance and retention: ~100K erase cycles per sector; data retention on the order of years.
- Package/variant: -4C-EKE denotes specific package and temperature/lead-frame variant; consult the datasheet for exact details.
- Applications: Non-volatile storage for firmware, code BIOS, boot ROMs, and embedded system data storage.
- Important notes: Erase-before-program, proper voltage levels, and using the correct command sequence and polling per the datasheet.
For exact block sizes, command sequences, and electrical characteristics, refer to the SST39VF200A datasheet.

Features

Concise features of SST39VF200A-70-4C-EKE:
- Density: 2 Mbit (256 K × 8) NOR flash
- Access time: 70 ns
- Voltage: Single 2.7–3.6 V supply
- Interface: Parallel asynchronous NOR flash
- Random read; simple command set
