W55Fxx Data Sheet
General Description
The W55Fxx is a serial flash memory series that is typically used as the contents upgradeable memory device of Internet toy applications, or applications with W51300 (VoiceRecorderTM controller) for voice message storage device. Besides that, W55Fxx can still be the W551Cxxx (Serial Voice Memory) program or data emulator. The single voltage supply eliminates the need for an extra pump circuit during flash memory cells programming and erasing.
1.1 W55Fxx Product Selection Guide
W55Fxx Serial Flash Memory is used to store pre-determined data or contents need to be upgradeable applications. To communicate with W55Fxx in serial data mode, the connection interface total pin counts can be reduced to five pins only. The following table is shown the product selection guide of part number vs. memory density.
Part # Density
W55F01 128K bits
W55F05 512K bits
W55F10A 1M bits
W55F20 2M bits
