Program and Erase commands are written to the Command Interface of the memory. An on-
chip Program/Erase Controller takes care of the timings necessary for program and erase
operations. The end of a program or erase operation can be detected and any error
conditions identified. The command set required to control the memory is consistent with
JEDEC standards.
All the devices are offered in TBGA64 (10 × 13mm) packages. 32 Mbit devices are also
delivered in TFBGA47 (6.39 × 6.37mm) packages.
In order to meet environmental requirements, ST offers the devices in ECOPACK
packages. ECOPACK packages are Lead-free. The category of second Level Interconnect
is marked on the package and on the inner box label, in compliance with JEDEC Standard
JESD97. The maximum ratings related to soldering conditions are also marked on the inner
box label. ECOPACK is an ST trademark. ECOPACK specifications are available at:
www.st.com.
All devices are supplied with all the bits erased (set to ’1’).
