Product Name : 2G-Bit 3.3V NAND FLASH MEMORY

Item No. : H7A12G24B5CN

Description

The H7A12G24B5CN (2G-bit) NAND Flash memory provides a storage solution for embedded systems with limited space, pins and power. It is ideal for code shadowing to RAM, solid state applications and storing media data such as,voice, video, text and photos. The device operates on a single 2.7V to 3.6V power supply with active current consumption as low as 25mA at 3V and 10uA for CMOS standby current.

The memory array totals 276,824,064 bytes, and organized into 2,048 erasable blocks of 135,168 bytes. Each block consists of 64 programmable pages of 2,112-bytes each. Each page consists of 2,048-bytes for the main data storage area and 64-bytes for the spare data area (The spare area is typically used for error management functions). The H7A12G24B5CN supports the standard NAND flash memory interface using the multiplexed 8-bit bus to transfer data, addresses, and command instructions.

The five control signals, CLE, ALE, #CE, #RE and #WE handle the bus interface protocol. Also, the device has two other signal pins, the #WP (Write Protect) and the RY/#BY (Ready/Busy) for monitoring the device status.
