Introduction

SST39SF040-70-4C-NHE is an extremely reliable and cost-effective non-volatile memory or NVRAM device manufactured by SST (Silicon Storage Technology). It is offered in a 32-pin 2x17-PIN plastic TSOP package. It has an industry-standard pin-out and is compliant with JEDEC standard specifications. The NHE can be used in a variety of applications and is especially ideal for rapid development and prototyping.

Specification

The SST39SF040-70-4C-NHE is a 32,768-bit non-volatile memory, organized as 4K words (16 bits each). It has a max write speed of 7 MHz, with a max read speed of 20MHz at 5V. Its operating voltage range is between 2.7V and 5.5V and it is capable of working in a temperature range of -40 to +85°C.The device features advanced features such as onboard write protect and reliable data retention up to 150 years. It is also RoHS compliant and is classed as ECOPACK Green, meeting international environmental requirements.

Application Field

The SST39SF040-70-4C-NHE is suitable for a wide range of applications, ranging from automotive to industrial applications, including:• Automotive/industrial controllers• Portable devices including cell phones and digital cameras• Video gaming systems• Handheld devices including PDAs, digital music players and MP3 players• Avionics and aerospace applications• Network access devices• Set-top boxesIn addition, it can also be used as a “flash replacement” in a variety of products.

Working Principle

As a non-volatile memory device, the SST39SF040-70-4C-NHE does not require a power supply for data retention. It also does not require a battery backup for device programming. The working principle of the device is simple – when programmed, data is stored permanently in the device, and retained until the device is res///et. The device operates using a serial bus protocol and is compatible with most microcontroller platforms.The device supports serial operation under three separate protocols: 8-bit single byte transfer for data byte programming, 32-bit quad byte transfer for page and block programming, and 64-bit octal byte transfer for global programming within the same device. Each protocol has its own write and/or read commands.

Conclusion

The SST39SF040-70-4C-NHE is a versatile, high performance non-volatile memory device with a vast range of applications, from automotive to consumer electronics. It has an industry-standard pin-out and is compliant with JEDEC specifications. Its advanced features such as onboard write protection and reliable data retention make it an ideal choice for a wide range of applications. Its easy-to-use serial protocol makes it the ideal choice for rapid development and prototyping.
