64Mb Parallel Flash Memory Device by Microchip

Microchip Technology Inc., provider of microcontroller, mixed-signal, analog and flash-IP solutions, introduced a new parallel flash memory device, the SST38VF6401B.

The SST38VF6401B is a 4Mx16 CMOS Advanced Multi-Purpose Flash Plus (Advanced MPF+) device manufactured with Microchip’s, high-performance CMOS SuperFlash technology, a split-gate cell design and thick-oxide tunneling injector for better reliability and manufacturability. This device conforms to JEDEC standard pin assignments for x16 memories.

With operating voltage range from 2.7 to 3.6V, fast read and program times, and advanced protection features, this parallel flash memory device excels in a variety of applications. The memory is partitioned into uniform 32 KWord and non-uniform 8 KWord blocks, offering flexible erase capabilities and seamless partitioning for program code and data.

The SST38VF6401B parallel flash device offers performance with flexible read and write options, including random read access time of 70ns, page read access time of 25ns, erasing sectors and blocks as fast as 18ms, erasing the entire flash memory chip in 40ms, and a word-programming time of 7µs, write-buffer programming time of 1.75µs, typical.

The device offers 100,000 endurance cycles, typical, and greater than 100 years of data retention. The active read current of these devices is 25mA, typical, at 5MHz, and standby current is 5µA, typical. It also provides various levels of protection and security features such as security-ID, hardware boot-block protection, individual block protection, password protection and irreversible block locking.

This device excels in a range of applications, including those in the consumer, automotive and industrial markets. Examples of end applications include set-top boxes, multifunctional printers, digital televisions, as well as audio, video and infotainment products for automobiles. Additionally, this parallel flash memory device is well for use in networking and industrial applications, such as gateways, switches and industrial control equipment.

“The introduction of parallel 64Mb Flash on our latest process technology showed Microchip’s steadfast commitment to deliver the code storage solutions to automotive, industrial and consumer markets,” said Randy Drwinga, VP of Microchip’s memory products division. “This product, among other flash products, continues to set the standards for the performance and reliability of NOR flash.“

The SST38VF6401B devices are available for sampling and volume production, in 48-pin TSSOP and 48-ball TFBGA packages, starting at $2.50 each, in 10,000 unit quantities.
