Microchip introduces 64-Mbit parallel flash memory device

CHANDLER, USA: Microchip Technology, a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today introduced a new parallel Flash memory device the SST38VF6401B. It is a 4M x16 CMOS Advanced Multi-Purpose Flash Plus (Advanced MPF+) device manufactured with Microchip's, CMOS SuperFlash technology, is 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 70 ns, page read access time of 25 ns, erasing sectors and blocks as fast as 18 ms, erasing the entire Flash memory chip in 40 ms, and a word-programming time of 7 µs, write-buffer programming time of 1.75 µs, typical. The device offers reliability of 100,000 endurance cycles, typical, and greater than 100 years of data retention. The active read current of these devices is only 25 mA, typical, at 5 MHz, and standby current is 5 µA, typical. The SST38VF6401B 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 has a broad range of applications, including those in the consumer, automotive and industrial markets. Additionally, this parallel Flash memory device is well suited for use in networking and industrial applications, such as gateways, switches and industrial control equipment.

Randy Drwinga, vice president of Microchip's Memory Products Division, said: "The introduction of parallel 64-Mbit Flash on our latest process technology showed Microchip's steadfast commitment to deliver the code storage solutions to automotive, industrial and consumer markets. This product, among other flash products, continues to set the standards for the performance and reliability of NOR flash."
