2.2.6 Memories
The motherboard has three memories; an M27C1001, which is an 128-Kbyte EPROM, an
M48Z128Y, which is an 128-Kbyte Zeropower® SRAM and an M29F040B, which is a
512-Kbyte single-supply FLASH memory. The datasheets for these devices are available on
the on ST web site, www.st.com. Ports P0, P1 and PC are used for addressing the various
memories. The microcontroller addresses the devices using the 6 most significant bits (PC) of
the 22 addresses which may be set automatically or manually via the I/O port. For instance, on
the ST90158 MCU, the segment number must be output on port P2. Each memory part is lo-
cated as follows.
