Additional Details

The AM29F200BB-120SE comes in a 44-pin SOP (Small Outline Package) or a 48-pin TSOP (Thin Small Outline Package). This device supports JEDEC standard commands for program and erase operations. It is designed to be compatible with older microcontroller and microprocessor systems. The '120' in the part number denotes the access time of 120 ns. The 'SE' suffix usually indicates the temperature range. Given its age, this flash memory is typically used in maintaining or repairing legacy systems where backward compatibility is critical. Sourcing may involve searching for older components from specialized distributors or surplus inventories. Always consult the datasheet to ensure compatibility with the target system's voltage, timing, and programming requirements. Before use, confirm the specified operating conditions to ensure reliable and consistent performance.
