Microchip introduced a new 64Mbit Serial Quad I/O memory device—SST26WF064C with proprietary SuperFlash® technology. The SST26WF064C writes with a single power supply of 1.65-1.95V and significantly lower power consumption. This makes it ideal for wireless, mobile, and battery-powered applications.

This 64Mbit memory device also features DTR or Dual Transfer Rate technology. DTR lets the user access data of the chip on both rising and falling edges of the clock, reducing overall data access time and power consumption significantly. The SST26WF064C utilizes a 4-bit multiplexed I/O serial interface to boost performance while maintaining the tiny form factor of standard serial flash devices.

Microchip’s high-performance CMOS SuperFlash technology provides the fastest chip erase time, consequently, reduces overall power consumption. It also improves performance and reliability of the memory chip. The SST26WF064C’s typical chip-erase time is 35-50 milliseconds, where other chips take nearly 30 seconds to be completely erased.

This chip combines a hardware controlled RESET function which is not present in common flash chips available in the market due to their limited pin count. In SST26WF064C, the user can program the HOLD pin to use for the RESET function. This feature lets the host microcontroller to reset the chip by sending a pulse to it.

SST26WF064C supports full command-set compatibility with traditional Serial Peripheral Interface (SPI) protocol. Operating at frequencies reaching 104 MHz, the SST26WF064C enables minimum latency execute-in-place (XIP) capability without the need for code shadowing on a SRAM. To learn about code shadowing, read this article.

The key features of the SST26WF064C are:

  • Single Voltage Read and Write Operations – 1.65-1.95V
  • Serial Interface Architecture
  • High-Speed Clock Frequency (104 MHz max.)
  • Burst Modes
