SST39VF1601C-70-4I-EKE-T

Memory IC Overview

The SST39VF1601C-70-4I-EKE-T is a 16 Mbit (1M x 16) NOR Flash memory manufactured using Microchip's SuperFlash technology. It operates on a single 2.7V to 3.6V power supply and features a 70 ns access time. The device utilizes a parallel interface with asynchronous timing and is housed in a 48-lead TSOP package. It supports sector, block, and chip erase capabilities, along with word-program operations.

Memory IC Feature Summary

• SuperFlash Technology for enhanced reliability and lower power consumption during program and erase cycles
• Hardware Block Protection via WP# pin to prevent inadvertent writes to specific boot blocks
• Multiple End-of-Write Detection methods including Toggle Bits, Data# Polling, and Ready/Busy# pin
• Integrated Security-ID feature with factory-programmed and user-programmable segments

Memory IC Applications

• Code storage for microcontrollers and embedded systems
• Configuration data storage in industrial equipment
• Firmware updates for network appliances
• Data logging applications requiring high endurance

Memory IC Procurement Notes

Verify the 'EKE' suffix indicates the 48-lead TSOP package and tape-and-reel shipping format as specified in the datasheet. Confirm the '4I' designation aligns with the required industrial temperature range of -40°C to +85°C. Ensure the ordering part number matches the exact density and organization requirements for your design.

Memory IC Selection Notes

Select this component when a 16 Mbit capacity with a 16-bit data bus width is required. The 70 ns speed suits most standard parallel interface applications. Consider the hardware protection features if system security against accidental overwrites is critical. Verify that the 2.7V to 3.6V voltage range matches the target system's power supply rails.

Memory IC Part Context

This part belongs to the SST39VF160xC series of Multi-Purpose Flash Plus devices. It shares architectural similarities with the SST39VF1602C but differs in boot block configuration, offering bottom protection instead of top protection. Both variants utilize the same SuperFlash process and command set.

Memory IC Replacement Considerations

SST39VF1601-70-4I-EKE-T: Older generation variant without the 'C' suffix; verify silicon revision compatibility.

Memory IC FAQ

How does the WP# pin function?

The WP# pin provides hardware block protection. When grounded, it prevents Program and Erase operations on the protected boot block (bottom 8 KWord for SST39VF1601C). If left floating, it is internally pulled high, leaving the block unprotected.

What are the available end-of-write detection methods?

The device supports three methods: Toggle Bits (DQ6 and DQ2), Data# Polling (DQ7), and the Ready/Busy# (RY/BY#) output pin. These allow the host system to monitor the status of internal Program or Erase operations.
