- 2 - 1. GENERAL DESCRIPTION The W55Fxx is a serial flash memory series that is typically used as the contents upgradeable memory device of Internet toy applicat ions, or applications with W51300 ( VoiceRecorderTM controller) for voice message storage device. Besides that, W55Fxx can st ill be the W551Cxxx (Serial Voice Memory) program or data emulator. The single volt age 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 # W55F01* W55F01B* W55F05B* W55F10A W55F10B* W55F10BG W55F20 Density 128K bits 128K bits 512K bits 1M bits 1M bits 1M bits 2M bits Notice: 1. * indicated prohibits cascade application just for single chip application only. 2. W55F10BG is lead free package version. 3. Programming voltage: W55Fxxx for high voltage (5Vmin.).
