ZMOTION® Intrusion Detection

Product Specification

Flash Memory Map

The Z8FS021 MCU is based on Zilog’s Z8F082A device, which contains a total of 8KB

Flash memory. Zilog’s PIR technology is located in the 6KB address range

0800h–1FFFh

, a code space that is locked and cannot be erased by the user or by the

Zilog Debug Interface (ZDI) mass erase or page erase commands. The remaining 2 KB of

this Flash memory space, in the address range 0000h–07FFh, is available for user appli-

cation code.

The Z8FS021 MCU is not preprogammed with application code. A generic version of the

ZMOTION Intrusion Detection source code (RD0001-SC01) can be downloaded from

zilog.com and programmed into the MCU.

A memory map of the Z8FS021 MCU’s Flash code space is illustrated in Figure 5.
