Integrated Silicon Solution 

IS25LQ040

SYSTEM CONFIGURATION

The IS25LQ040 devices are designed to interface directly with the synchronous Serial Peripheral Interface (SPI)

of the Motorola MC68HCxx series of microcontrollers or any SPI interface-equipped system controllers. The

devices have two superset features that can be enabled through specific software instructions and the

Configuration Register:

1. Configurable sector size: The memory array of

IS25LQ040 is divided into uniform 4 KByte sectors or uniform 64 KByte blocks (a block consists of sixteen

adjacent sectors).

Table 1 illustrates the memory map of the devices.
