The H7A41G25B4CG (1G-bit) Serial SLC NAND Flash Memory provides a storage solution for systems with limited space, pins and power. The H7A41G25B4CG incorporates the popular SPI interface and the traditional large NAND non-volatile memory space. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 25mA active and 10μA for standby.
H7A41G25B4CG was offered in space-saving packages which were impossible to use in the past for the typical NAND flash memory. The H7A41G25B4CG 1G-bit memory array is organized into 65,536 programmable pages of 2,048-bytes each. The entire page can be programmed at one time using the data from the 2,048-Byte internal buffer. Pages can be erased in groups of 64 (128KB block erase).
The H7A41G25B4CG has 1,024 erasable blocks and supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to 104MHz are supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 416MHz (104MHz x 4) for Quad I/O when using the Fast Read Dual/Quad I/O instructions.The H7A41G25B4CG supports JEDEC standard manufacturer and device ID, one 2,048-Byte Unique ID page, one 2,048-Byte parameter page and ten 2,048-Byte OTP pages. To provide better NAND flash memory manageability, user configurable internal ECC, bad block management are also available in H7A41G25B4CG.
