M6MGB/T160S4BVP
When setting BYTE# at the low level and other pins are in
anactive stage , lower-byte I/O are in a selesctable mode in
whichboth reading and writing are enabled, and upper-byte are
in anon-selectable mode.
When setting S-CE at a low level,the chips are in a
non-selectable mode in which both reading and writing are
disabled. In this mode, the output stage is in ahigh-impedance
state, allowing OR-tie with other chips and memory expansion
by S-CE.
The power supply current is reduced as low as 0.3
m
A(25
C,typical), and the memory data can be held at +2V
powersupply, enabling battery back-up operation during power
failure or power-down operation in the non-selected mode.
The SRAM of M6MGB/T160S4BVP is organized as
262,144-word by 16-bit/ 524,288-word by 8-bit. These
devices operate on a single +2.7~3.6V powersupply, and are
directly TTL compatible to both input and output. Its fully
static circuit needs no clocks and no refresh, and makes it
useful.
The operation mode are determined by a combination of
the device control inputs BYTE#, S-CE , WE# and OE#.
Each mode is summarized in the function table.
A write operation is executed whenever the low level WE#
overlaps with the high level S-CE. The address(A-1~A17:byte
mode, A0~A17:word mode) must be set up before the write
cycle and must be stable during the entire cycle.
A read operation is executed by setting WE# at a high level
and OE# at a low level while S-CE are in an active
state(S-CE=H).
