DESCRIPTION
The M58BF008 is a family of 8 Mbit non-volatile
Flash memories that can be erased electrically at
the blocklevel and programmed in-system. Family
members are configured during product testing for
a specific Synchronous or Asynchronous Write
mode, a Burst default of Wrap or No-wrap and for
Critical Word X = 3 or 4 and Burst Word Y = 1 or 2
latency times. The Main memory array matrix al-
lows each of the 32 equal blocks of 256 Kbit to be
erased separately and re-programmed without af-
fecting other blocks. The memory features a
256 Kbit Overlay block having the same address
space asthe firstMain memory block. The Overlay
block provides a secure storage area that is con-
trolled by special Instructions and an external in-
put. A separate supply V
DDQ
allows the Input/
Output signals to be at 3.3Vlevels, while the main
supply V
DD
is 5V.
