Microchip aims parallel flash at consumer gear

Microchip has introduced a general-purpose fast parallel flash memory chip.

SST38VF6401B is a 4M x16 CMOS with a split-gate cell design and thick-oxide tunneling injector for better reliability and manufacturability.

Operating is from 2.7 to 3.6V and the memory is partitioned into uniform 32kword and non-uniform 8kword blocks.

Various levels of protection are provided, including Security-ID, hardware boot-block protection, individual block protection, password protection, and irreversible block locking.

This device conforms to JEDEC standard pin assignments for x16 memories and comes in 48pin TSSOP and 48ball TFBGA.

Applications are expected in consumer, automotive and industrial markets, for example: set-top boxes, multi-function printers, digital TVs, audio, video and car infotainment.
