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
IS25LQ080 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.
