Microchip introduces 3V 16-Mbit, 32-Mbit and 64-Mbit Serial Quad I/O™ interface SuperFlash® memory family

Microchip announces a new family of 3V Serial Quad I/O™ (SQI™) interface Super Flash® memory devices: the SST26VF. This three-member “26 Series” SQI

interface family is available with 16-Mbit, 32-Mbit or 64-Mbit of memory and is manufactured using Microchip’s high-performance CMOS SuperFlash technology, which provides the industry’s fastest erase times and superior reliability. The SST26VF memory family provides the fastest erase times in the industry, due to its use of SuperFlash technology. Sector and block erase commands are completed in just 18ms, and a full chip erase operation is completed in 35ms. Competing devices require 10 to 20 seconds to complete a full chip erase operation, making the SST26VF approximately 400 times faster. These fast erase times can provide a significant cost savings to customers, by minimising the time required for testing and firmware updates, and therefore increasing their manufacturing throughput. Microchip’s SQI interface is a low pin-count, high-speed 104MHz quad-bit address and data multiplex I/O serial interface, which allows for high data throughput in a small package. This interface enables low-latency execute-in-place (XIP) capability with minimal processor buffer memory, reducing the overall design footprint compared to traditional parallel memory interfaces. The SST26VF family provides faster data throughput than a comparable x16 parallel Flash device, without the associated high cost and high pin-count of parallel Flash.
