LE25FU106B - CMOS IC 1M-bit (128K X 8) Serial Flash Memory

General Description

Symbol SCK Pin Name Serial clock This pin controls the data input/output timing.

The input data and addresses are latched synchronized to the rising edge of the serial clock, and the data is output synchronized to the falling edge of the serial clock.

Key Features

  • inherent to a serial flash memory device, the LE25FU106B is housed in an 8-pin ultra-miniature package. Serial flash memory devices tend to be at a disadvantage in terms of their read speed, but the LE25FU106B has maximally eliminated this speed-related disadvantage by supporting clocks with frequencies up to 30MHz under SPI bus specifications. All these features make this device ideally suited to storing program codes in.

Ordering number : EN*A1140 LE25FU106B Overview CMOS IC 1M-bit (128K×8) Serial Flash Memory The LE25FU106B is a serial interface-compatible flash memory device with a 128K × 8-bit configuration. It uses a single 2.5V power supply for both reading and writing (program and erase functions) and does not require a special power supply. As such, it can support on-board programming. It has three erase functions, each of which corresponds to the size of the memory area in which the data is to be erased at one time: the small sector (4K bytes) erase function, the sector (32K bytes) erase function, and the chip erase function (for erasing all the data together). The memory space can be efficiently utilized by selecting one of these functions depending on the application.
