The M36D0R6040T0 and M 36D0R6040B0 combine two memory devices in a Multi-Chip Package:
a 64-Mbit, Multiple Bank Flash memory, the
M58WR064FT/B, and a 16-Mbit Pseudo SRAM,
the M69AR024B. Recommended operating conditions do not allow more than one memory to be active at the same time.
The memory is offered in a Stacked TFBGA67
(12 x 8mm, 8x8 ball array, 0.8mm pitch) package.
In addition to the stan dard version, the pac kages
are also available in Lead- free version , in comp liance with JEDEC Std J-STD-020 B, the ST ECOPACK 7191395 Specification, and the RoHS
(Restriction of Hazardous Substances) directive.
All packages are c omp lia nt with Le ad- fr ee so ld er ing processes.
The memory is supplied with all the bits erased
(set to ‘1’).

SIGNAL DESCRIPTIONS
See Figure 2., Logic Diagram and Table 1., Signal
Names, for a brief overview of the signals connect-
ed to this device.Address Inputs (A0-A19). Addresses A0-A19
are common inputs for the Flash Memory and
PSRAM components. T he Address Inputs select
the cells in the memory array to access during Bus
Read operations. During Bus Write operations
they control the command s sent to the Comma nd
Interface of the Flash memory internal state machine and they select the cells to access in the
PSRAM.
The Flash memory is acce ssed through the Chip
Enable signal (E
) signal, while the PSRAM is accessed
(W
F
through two Chip Enable signals (E1
and the Write Enable signal (W
Address Inputs (A20-A21). Addresses A20-A21
are inputs for the Fl ash Memo ry compon ent only.
The Flash Memory is acce ssed through the Chip
Enable signals (
(W
) signal.
F
Data Input/Output (DQ0-DQ15). The Data I/O
outputs the data stored at the selected address
during a Bus Read operation or inputs a command
or the data to be progra mmed d uring a Write Bus
operation.
Flash Chip Enable (E
puts activate the memory control logics, input buffers, decoders and sense amplifiers. When Chip
Enable is Low, V
vice is in active mode. When Chip Enable is at V
the Flash memory is deselec ted, the outputs are
high impedance and the power consumption is reduced to the standby level.
Flash Output Enable (G
pins control data outputs during Flash memory
Bus Read operations.
Flash Write Enable (
controls the Bus Write operation of the Flash
memories’ Command Int erface. The data an d address inputs are latched on the rising edge of Chip
Enable or Write Enable whichever occurs first.
Flash Write Protect (WP
input that gives an additio nal hardware protection
for each block. When Write Protect is Low, V
Lock-Down is enabled and the protection status of
the Locked-Down blocks cannot be changed.
When Write Protect is a t High, V
disabled and the Locked-Down blocks can be
locked or unlocked. (Refer to Lock Status Table in
M58WR064F(T/B) datasheet).

normal operation. Exiti ng Reset mode the devic e
enters Asynchronous Read mode, but a nega tive
transition of Chip Enable or Latch Enable is required to ensure valid data outputs.
The Reset pin can be interfaced with 3V logic without any additional circui try. It can be tied to V
(refer to Table 8., Flash Memory DC Characteris-
tics - Voltages).
PSRAM Chip Enable (E1
(Low), the Chip Enable, E1
). When asserted

, activates the memo-
P
ry state machine, address buffers and decod ers,
allowing Read and Write operations to be performed. When de-asserted (High), all other pins
are ignored, and the device is put, automatically, in
low-power Standby mode.
