SUMMARY DESCRIPTION

The M36W432TG is a low voltage Multiple Memo-

ry Product which combines two memory devices;

a 32 Mbit boot block Flash memory and a 4 Mbit

SRAM. Recommended operating conditions do

not allow both the Flash and SRAM devices to be

active at the same time.

The memory is offered in a Stacked LFBGA66

(12x8mm, 8x8 active ball array, 0.8 mm pitch)

package and is supplied with all the bits erased

(set to ‘1’).
