DESCRIPTION The A472G is multi-chip device containing an 8 Mbit boot block Flash memory and a 1 Mbit of SRAM. The device is offered in the new Chip Scale Package solutions: LBGA48 1.0 mm ball pitch and LGA48 1.0 mm land pitch. The two components, of the packages overall 9 Mbit of memory, are distinguishable by use of the three chip enable lines: EF for the Flash memory, E1S and E2S for the SRAM. The Flash memory component is identical with the M29W008 device. It is a non-volatile memory that may be erased electrically at the block or chip level and programmed in-system on a Byte-by-Byte ba- sis using only a single 2.7V to 3.6V V CCF supply. For Program and Erase operations the necessary high voltages are generated internally. The device can also be programmed in standard program- mers. The array matrix organization allows each block to be erased and reprogrammed without af- fecting other blocks.
