PRETEC PCMCIA Linear Flash Card Series 100 conform to PCMCIA/JEIDA international standard but with word (16bit) operation only. Without the complicated control logic circuit and attribute memory design, it is the low cost version of PRETEC PCMCIA Linear Flash Card Series 5. PRETEC PCMCIA Linear Flash Card Series 100 consist of multiple Intel’s 28F008S5 (or 28F016S5) or compatible, maintains backwards-compatibility with Series 2 family, key enhancements include: smart voltage allows Vpp to be 5V or 12V, 12V option renders the faster block erase, program performance; enhance suspend capabilities; in-system block locking.
This series Flash memory cards contain 16, 32, 64 or 128 independent 64K-word blocks. Each block can be individually erasable. To reduce the attribute memory cost overhead, the Card Information Structure (CIS) is stored in Block 0 of the flash memory array. In embedded applications, the CIS may not be required by the system and the entire flash memory array can be used by the system.
