7 / 60 page NAND08GW3C2B, NAND16GW3C4B 1 Description 7/60 1 Description The NAND08GW3C2B and NAND16GW3C4B are multilevel cell (MLC) devices from the NAND Flash 2112-byte page family of non-volatile Flash memories. The NAND08GW3C2B and the NAND16GW3C4B have a density of 8- and 16-Gbit, respectively. The NAND16GW3C4B is composed of two 8-Gbit dice; each die can be accessed independently using two Chip Enable and two Ready/Busy signals. The devices operate from a 3 V VDD power supply. The address lines are multiplexed with the data input/output signals on a multiplexed x8 input/output bus. This interface reduces the pin count and makes it possible to migrate to other densities without changing the footprint. Each block can be programmed and erased over 10,000 cycles (with error correction code (ECC) on). The device also has hardware security features; a write protect pin is available to provide hardware protection against program and erase operations. The devices feature an open-drain, ready/busy output that identifies if the Program/Erase/Read (P/E/R) Controller is currently active. The use of an open-drain output allows the ready/busy pins of several memories to be connected to a single pull-up resistor. The memory array is split into 2 planes of 2048 blocks each. This multiplane architecture makes it possible to program 2 pages at a time (one in each plane) or to erase 2 blocks at a time (one in each plane), dividing by two the average program and erase times. The devices have the Chip Enable ’don’t care’ feature, which allows code to be directly downloaded by a microcontroller, as Chip Enable transitions during the latency time do not stop the Read operation. There is the option of a unique identifier (serial number), which allows the NAND08GW3C2B and the NAND16GW3C4B to be uniquely identified. It is subject to an NDA (non-disclosure agreement) and is, therefore, not described in the datasheet. For more details of this option contact your nearest Numonyx sales office. The devices are available in TSOP48 (12 × 20 mm) and LGA52 (12 x 17 x 0.65 mm) packages. They are shipped from the factory with block 0 always valid and the memory content bits, in valid blocks, erased to ‘1’. Refer to the list of available part numbers and to Table 26: Ordering information scheme for information on how to order these options. |
