Product details

16 Mbit parallel NOR flash for code-shadow and data-logging

The SST39VF1601-70-4I-EKE-T is a 16 Mbit parallel NOR flash from Microchip's SST39 MPF™ series, organized as 1M x 16 bits. Its 70 ns access time means the CPU can execute code directly from the flash without wait-states on most 16-bit bus controllers running below 14 MHz — useful for boot code or firmware shadowed into RAM at power-up.

Package and board-fit — 48-TSOP footprint

The surface-mount footprint matches legacy 48-pin TSOP layouts, so a board already routed for a 48-TSOP flash can take this part without a respin.

Write performance and firmware update strategy

Write cycle time is 10 µs per word or page — a full 16 Mbit firmware image at 1M words takes roughly 10 seconds to program in-page mode, assuming the controller meets the timing. This is fast enough for field-updatable firmware in networked equipment but slower than SPI NOR; the trade-off is the parallel interface's higher read throughput for code execution.

Active lifecycle and compliance posture

It is ROHS3 compliant, so it clears EU and UKCA regulatory gates without an exemption declaration.

Frequently asked questions

Where can I buy SST39VF1601-70-4I-EKE-T and check current pricing?

Submit an RFQ for a firm price and lead-time window.

Can SST39VF1601-70-4I-EKE-T replace AT24C08D-SSHM-B on the same board?

No — the AT24C08D-SSHM-B is an 8 Kbit I²C EEPROM in a different package and interface. The SST39VF1601 is a 16 Mbit parallel NOR flash with a 48-TSOP footprint and a 70 ns access time. They are not pin-compatible or functionally interchangeable without a board redesign.

What compliance documentation does Microchip provide for SST39VF1601-70-4I-EKE-T?

Microchip confirms ROHS3 compliance. Standard documentation includes the datasheet, material declaration, and PCN notifications for any process changes — available through the manufacturer's document portal or upon request with your RFQ.
