Parallel Flash

Part No.	W19B320B
Datasheet	W19B320B.pdf
Description	The W19B320BT/B is a 32Mbit, 2.7~3.6-volt single bank CMOS flash memory organized as 4M x 8 or 2M x 16 bits. The word-wide ( x 16) data appears on DQ15-DQ0, and byte-wide (x 8) data appears on DQ7-DQ0. The device can be programmed and erased in-system with a standard 3.0-volt power supply. A 12-volt VPP is not required. The unique cell architecture of the W19B320BT/B results in fast program/erase operations with extremely low current consumption (compared to other comparable 3-volt flash memory products). The device can also be programmed and erased by using standard EPROM programmers.
Features	Manufactured on WinStack-S 0.13um process technology Operating Voltage: 3.0V (2.7V-3.6V) Organization: 4Mbx8 / 2Mbx16 Speed: 70ns Single bank Boot Block: Top / Bottom Secured Silicon Sector (256 Byte)
