Microchip Technology has introduced a new 1.8V Serial Quad I/O SuperFlash memory device. The SST26WF06C is a low voltage 64 megabit device that combines Dual Transfer Rate (DTR) with proprietary SuperFlash NOR Flash technology, thus making it ideally suitable for wireless and battery-powered applications.

 

DTR allows customers to output data on both edges of the clock which not only reduces the overall data access time but also brings down the power consumption. The typical chip erase time for the SST26 WF064C ranges between 35 and 50 milliseconds (ms), while the competitive flash devices take more than 30 seconds to erase.

 

The device comes with a hardware-controlled reset functionality allowing a robust device reset. Most of the Serial Flash devices in the market have pin count limitations due to which they do not support the hardware reset function. 

 

 

Operating at frequencies reaching 104 MHz, the device enables minimum latency execute-in-place (XIP) capability without the need for code shadowing on Static Random Access Memory (SRAM). 

 

The SST26WF064C utilizes a 4-bit multiplexed I/O serial interface to boost performance while maintaining the compact form factor of standard serial Flash devices. It also supports full command-set compatibility to the traditional Serial Peripheral Interface (SPI) protocol.

The SST26WF064C is offered in a variety of package options including an 8-contact WDFN (6 mm x 5 mm), 8-lead SOIJ (5.28 mm), 16-lead SOIC (7.50 mm) and 24-ball TBGA (8 mm x 6 mm). Devices are available today in volume production starting at $2.05 each in 10,000 unit quantities.
