SST39WF1601-70-4C-Y1QE

Memory IC Overview

The SST39WF1601-70-4C-Y1QE is a 16 Mbit (1M x 16) Multi-Purpose Flash Plus memory device manufactured by Microchip Technology. It operates on a single 1.65V to 1.95V power supply and features asynchronous parallel interface with 70 ns access time. The component utilizes SuperFlash technology for high reliability, offering 100,000 cycle endurance and over 100 years data retention. It supports sector, block, and chip erase capabilities with hardware and software data protection schemes.

Memory IC Feature Summary

• SuperFlash technology ensures superior reliability with fixed erase and program times independent of cycle count.
• Hardware block protection allows selective locking of the bottom 32 KWord boot block via the WP# pin.
• Integrated Security-ID feature provides 256-bit space divided into factory-programmed and user-programmable segments.
• Supports Erase-Suspend/Erase-Resume operations to allow reading or programming in non-suspended sectors.

Memory IC Applications

• Economical updating of program, configuration, or data memory in embedded systems.
• Applications requiring convenient and reliable non-volatile storage with low power consumption.
• Systems needing hardware-protected boot blocks for secure code execution.

Memory IC Procurement Notes

Verify that the ordering suffix Y1QE corresponds to the specific package and temperature grade required, as datasheet documentation primarily references MAQE and B3KE packages. Confirm availability status as this part number may be subject to End-of-Life notices associated with the broader SST39WF160x series. Ensure compatibility with 1.65V-1.95V supply rails and WFBGA-48 footprint requirements during procurement planning.

Memory IC Selection Notes

Select this component for designs requiring 16 Mbit capacity with a 16-bit data bus width and 70 ns speed. It is suitable for commercial temperature range applications (0°C to +70°C). Consider the SST39WF1602 if top block protection is preferred over the bottom block protection provided by the SST39WF1601 architecture. Ensure system voltage matches the 1.65V-1.95V specification strictly.

Memory IC Part Context

This device belongs to the SST39WF160x family of Multi-Purpose Flash Plus memories. It shares architectural similarities with the SST39VF160x series but operates at a lower voltage range (1.65V-1.95V vs 2.7V-3.6V). The SST39WF1601 variant specifically designates bottom boot block protection, distinguishing it from the SST39WF1602 which offers top block protection.
