PCMCIA Flash Memory Card FLF10 Series High Density FLASH Memory Card General Description WEDC’s Flash memory cards - FLF10 Series - offer high density linear Flash memory for code and data storage, high performance disk emulation, mobile PC and embedded applications. .. The WEDC FLF10 series is based on Intel’s Multi Level Cell (MLC) Flash memory technology, providing high density Flash ponents at a significantly lower cost per megabyte. MLC technology allows for two bits of information to be stored in a single cell. This leads to reduced die size and reduced cost per megabyte. WEDC’s FLF10 series cards are built with Intel’s 128Mb memory ponent, 28F128J3A, with a manufacturer/device ID of 89/18H. The FLF10 series is available in densities of 32, 64, 96, 128, 160, and 192MB. WEDC’s FLF10 series provides densities from 32MB to 192MB, in 32MB increments. The cards up to the 64MB density operate in the regular PCMCIA mode. The densities beyond the 64MB density are implemented using a “paging scheme”, which is also supported by the PCMCIA standard. By writing a page address to the Configuration Option Register (address 4000H), an additional page of memory can be accessed. The current FLF10 series supports densities to 192MB: total of 3 pages: page 0 := 64MB, page 1 := 64MB, and page 2 := 64MB. The FLF10 series card operates in a wide, universal voltage range, from 3V to 5V, allowing full “plug and play” functionality and upgrade solutions in all mobile, battery powered applications. Each memory ponent in the card also has a 128-bit Protection Register, containing 64 bits of User Programmable OTP (One Time Programmable) Cells. These cells can be programmed with a numeric security measure, such as an electronic signature. To provide a 16 bit word wide access supported by the PCMCIA standard, devices are paired on the card. Therefore, the Flash array is structured in 128K word (256k B) blocks. Write, read and block erase operations can be...
