Serial interface NAND flash memory for embedded applications

Rutronik has expanded its portfolio of memory products for embedded applications with the new line-up of 24nm SLC NAND flash memory products from Toshiba. The devices are compatible with the widely used Serial Peripheral Interface (SPI). New functional requirements increase the demand of embedded memory, for software (boot programs, firmware, embedded OS) and data (including log data). This causes product designers to move to SLC NAND flash memory, for high density and high reliability. The new line-up from Toshiba covers densities of 1Gbit, 2Gbit and 4Gbit and is available in either SOP (10.3mm x 7.5mm) or WSON (6mm x 8mm) packages. Each density or device combination is available with a choice of input voltage compatibility of either 1.8V or 3.3V. High-speed sequential read functions, embedded ECC (Error Correction Code) with bit flip report function and embedded data protection features ensure data can be accessed quickly while being stored safely and securely. The Serial Peripheral Interface gives users access to an SLC NAND flash memory with a low pin count, small package and large capacity. Serial Interface NAND has a much lower cost per bit than the NOR flash memory solutions traditionally used in embedded applications. With an operating temperature range of -40C to +85C the devices are suitable for the vast majority of consumer and industrial embedded applications, says the company.
