S29VS128RABBHI000A is listed in the Memory IC range at ChipApex. The manufacturer field lists Spansion. Its product description is PARALLEL NOR FLASH, 1.8V, 128MB. Review the specifications below when checking this part for your BOM.
The S29VS128RABBHI000A is a 128 Megabit (16 Megabyte) parallel NOR flash memory device manufactured by Spansion. It operates exclusively at 1.8 Volts and utilizes the MirrorBit technology on a 65 nm process. The component features a 16-bit data width and supports multiplexed burst access modes for high-speed data retrieval. It is housed in a lead and halogen-free package, designed for synchronous and asynchronous operations within embedded systems requiring reliable non-volatile storage.
Verify the specific suffix codes against the official Spansion datasheet to confirm pinout compatibility and temperature range. Ensure the source document explicitly lists S29VS128RABBHI000A as an active or supported part number. Cross-reference the package dimensions and pitch with mechanical drawings before integration. Confirm RoHS compliance status through the manufacturer's latest certification documents rather than distributor claims.
Select this component when a 1.8V-only operation is required for low-power embedded designs. The 16-bit interface suits applications needing wider data buses without increasing pin counts significantly. Consider the MirrorBit architecture for its endurance characteristics compared to traditional floating gate technologies. Evaluate the burst access capability if sequential data reading performance is critical for the target application.
This part belongs to the Spansion S29VS series of NOR flash memories. It shares architectural similarities with other devices in the family but is distinct due to its specific voltage requirements and 16-bit configuration. The series is known for integrating advanced programming algorithms and robust security features suitable for code execution in place (XIP).
Check for direct substitutes within the S29VS family that match the 1.8V specification and 16-bit width. Verify pin-to-pin compatibility if replacing in existing PCB layouts. Ensure any alternative maintains the same MirrorBit technology generation for similar endurance profiles.
