5. SYSTEM CONFIGURATION

The IS25WQ040/020 is designed to interface directly with the synchronous Serial Peripheral Interface (SPI)

microcontrollers or any SPI interface-equipped system controllers.

The memory array of IS25WQ040/020 is divided into uniform 4 Kbyte sectors or uniform 32/64 Kbyte blocks (a

block consists of eight/sixteen adjacent sectors respectively).

Table 5.1 illustrates the memory map of the device. The Status Register controls how the memory is protected.
