MB85RS1MT
■ DESCRIPTION
MB85RS1MT is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 131,072
words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the
nonvolatile memory cells.
MB85RS1MT adopts the Serial Peripheral Interface (SPI).
The MB85RS1MT is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS1MT can be used for 1013 read/write operations, which is a significant
improvement over the number of read and write operations supported by Flash memory and E2PROM.
MB85RS1MT does not take long time to write data like Flash memories or E2PROM, and MB85RS1MT takes
no wait time.

Pin No. Pin Name
Functional description
CS
Chip Select pin
This is an input pin to make chips select. When CS is “H” level, device is in deselect
(standby) status and SO becomes High-Z. Inputs from other pins are ignored for this
time. When CS is “L” level, device is in select (active) status. CS has to be “L” level before
inputting op-code. The Chip Select pin is pulled up internally to the VDD pin.
WP
Write Protect pin
This is a pin to control writing to a status register. The writing of status register (see “■
STATUS REGISTER”) is protected in related with WP and WPEN. See “■ WRITING
PROTECT” for detail.

HOLD
Hold pin
This pin is used to interrupt serial input/output without making chips deselect. When
HOLD is “L” level, hold operation is activated, SO becomes High-Z, SCK and SI become

to SCK. The SI value is invalid for this time. SO is output synchronously to a falling edge of SCK. In the
RDSR command, repeated reading of status register is enabled by sending SCK continuously before rising
of CS. RDSR command is applicable to “Up to 25 MHz (1.8 V to 2.7 V) and 30 MHz (2.7 V to 3.6 V) operation”.

• WRSR
The WRSR command writes data to the nonvolatile memory bit of status register. After performing WRSR
op-code to a SI pin, 8 bits writing data is input. WEL (Write Enable Latch) is not able to be written with WRSR
command. A SI value correspondent to bit 1 is ignored. Bit 0 of the status register is fixed to “0” and cannot
be written. The SI value corresponding to bit 0 is ignored. WP signal level shall be fixed before performing
WRSR command, and do not change the WP signal level until the end of command sequence. WRSR
command is applicable to “Up to 25 MHz (1.8 V to 2.7 V) and 30 MHz (2.7 V to 3.6 V) operation”.

• READ
The READ command reads FRAM memory cell array data. Arbitrary 24 bits address and op-code of READ
are input to SI. The 7-bit upper address bit is invalid. Then, 8-cycle clock is input to SCK. SO is output
synchronously to the falling edge of SCK. While reading, the SI value is invalid. When CS is risen, the READ
command is completed, but keeps on reading with automatic address increment which is enabled by continuously sending clocks to SCK in unit of 8 cycles before CS rising. When it reaches the most significant
address, it rolls over to the starting address, and reading cycle keeps on infinitely. READ command is
applicable to “Up to 25 MHz (1.8 V to 2.7 V) and 30 MHz (2.7 V to 3.6 V) operation”.

• WRITE
The WRITE command writes data to FRAM memory cell array. WRITE op-code, arbitrary 24 bits of address
and 8 bits of writing data are input to SI. The 7-bit upper address bit is invalid. When 8 bits of writing data is
input, data is written to FRAM memory cell array. Risen CS will terminate the WRITE command, but if you
continue sending the writing data for 8 bits each before CS rising, it is possible to continue writing with
automatic address increment. When it reaches the most significant address, it rolls over to the starting
address, and writing cycle can be continued infinitely. WRITE command is applicable to “Up to 25 MHz (1.8
V to 2.7 V) and 30 MHz (2.7 V to 3.6 V) operation”.

The FSTRD command reads FRAM memory cell array data. Arbitrary 24 bits address and op-code of FSTRD
are input to SI followed by 8 bits dummy. The 7-bit upper address bit is invalid. Then, 8-cycle clock is input
to SCK. SO is output synchronously to the falling edge of SCK. While reading, the SI value is invalid. When
CS is risen, the FSTRD command is completed, but keeps on reading with automatic address increment
which is enabled by continuously sending clocks to SCK in unit of 8 cycles before CS rising. When it reaches
the most significant address, it rolls over to the starting address, and reading cycle keeps on infinitely. FSTRD

• RDID
The RDID command reads fixed Device ID. After performing RDID op-code to SI, 32-cycle clock is input to
SCK. The SI value is invalid for this time. SO is output synchronously to a falling edge of SCK. The output
is in order of Manufacturer ID (8bit)/Continuation code (8bit)/Product ID (1st Byte)/Product ID (2nd Byte).
In the RDID command, SO holds the output state of the last bit in 32-bit Device ID until CS is risen. RDID
command is applicable to “Up to 25 MHz (1.8 V to 2.7 V) and 30 MHz (2.7 V to 3.6 V) operation”.

• SLEEP
The SLEEP command shifts the LSI to a low power mode called “SLEEP mode”. The transition to the SLEEP
mode is carried out at the rising edge of CS after operation code in the SLEEP command. However, when
at least one SCK clock is inputted before the rising edge of CS after operation code in the SLEEP command,
this SLEEP command is canceled.
After the SLEEP mode transition, SCK and SI inputs are ignored and SO changes to a Hi-Z state.

Returning to an normal operation from the SLEEP mode is carried out after tREC (Max 400 μs) time from the

is prohibited to bring down CS to L level again during tREC period.

■ HOLD OPERATION
Hold status is retained without aborting a command if HOLD is “L” level while CS is “L” level. The timing for
starting and ending hold status depends on the SCK to be “H” level or “L” level when a HOLD pin input is
transited to the hold condition as shown in the diagram below. In case the HOLD pin transited to “L” level
when SCK is “L” level, return the HOLD pin to “H” level at SCK being “L” level. In the same manner, in case
the HOLD pin transited to “L” level when SCK is “H” level, return the HOLD pin to “H” level at SCK being “H”
level. Arbitrary command operation is interrupted in hold status, SCK and SI inputs become do not care.
And, SO becomes High-Z while reading command (RDSR, READ). If CS is rising during hold status, a
command is aborted. In case the command is aborted before its recognition, WEL holds the value before
transition to hold status.
