Winbond releases Serial Flash Memories

16 and 32 megabit SpiFlash® memories in space-saving, cost-effective SO8

• Dual-Output SPI supports more than 18 megabyte/second transfer rate
• 4K-byte sectors improve memory utilization, voice and parameter storage
  

Winbond Electronics Corporation today announced two new members of the SpiFlash® 25X family utilizing the company's 0.13 micron Winstack Flash technology. The W25X16 and W25X32 offer 16- and 32-megabit densities that fit into space-saving and cost-effective 8-pin 208mil SO8 packaging, the highest density Serial Flash memories available in this small form factor. Similar to Winbond's popular W25X10/20/40/80 (one through eight-megabit SpiFlash memories), the W25X16 and W25X32 feature the industry's highest performance and flexible 4K-byte erasable sectors throughout the memory array. The packaging, performance and flexibility of the W25X16 and W25X32 make them ideal for a wide range of electronic applications including DVD drives and recorders, desktop and notebook PCs, WLAN devices, DSL modems, printers, cordless phones and more.

High density Serial Flash memories (16 megabit and greater) are commonly packaged in a larger and more costly 16-pin 300mil SO16 with 8-unused pins. Winbond's W25X16 and W25X32 are available in an 8-pin 208mil SO8 that uses half the space of a 16-pin SOIC resulting in smaller and simpler printed circuit boards. The SO8 package also allows for a common foot print from 4M-bit to 32M-bit densities.

The W25X16 and W25X32 support standard SPI clock rates of up to 75MHz. This performance can be further improved to an equivalent of 150MHz clock rate (>18 megabyte/second) by using the optional Dual-Output Read instruction. The instruction provides two bits of data per clock while maintaining the same 4-pin SPI interface. The "double data rate" makes the 25X family the highest performance serial Flash available today allowing controllers to quickly shadow or cache code to RAM and even execute code directly from the SPI interface.

The W25X16 and W25X32 also feature uniform 4K-byte erasable sectors and 64K-byte erasable blocks through the entire array. The small 4K-byte sectors allow for flexible and efficient memory allocation for code, as well as storage of parameter and configuration data typically handled by EEPROMs. The 4K-byte size is also effective for applications that record and play back voice or audio clips such as coreless phones, answering machines, games and talking electronic products.

Availability, Pricing

The W25X16VSSIG (16M-bit, 208mil SO8) is currently sampling and the W25X32VSSIG (32-bit, 208mil SO8) is sampling in December 2006. Both products are available for production in Q1 2007. Alternate packages include SO16 and WSON. For specific lead-time, pricing and additional information, please contact your local Winbond Electronics representative or distributor.
