Memory FRAM
128K (16 K × 8) Bit SPI
MB85RS128B
■ DESCRIPTION
MB85RS128B is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 16,384
words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the
nonvolatile memory cells.
MB85RS128B adopts the Serial Peripheral Interface (SPI).
The MB85RS128B is able to retain data without using a back-up battery, as is needed for SRAM.
The memory cells used in the MB85RS128B can be used for 1012 read/write operations, which is a significant
improvement over the number of read and write operations supported by Flash memory and E2PROM.
MB85RS128B does not take long time to write data like Flash memories or E2PROM, and MB85RS128B
takes no wait time.

■ PIN FUNCTIONAL DESCRIPTIONS
Pin No. Pin Name
CS
Chip Select pin
This is an input pin to make chips select. When CS is the “H” level, device is in deselect
(standby) status and SO becomes High-Z. Inputs from other pins are ignored at this time.
When CS is the “L” level, device is in select (active) status. CS has to be the “L” level
before inputting op-code.
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.
7
HOLD
Hold pin
This pin is used to interrupt serial input/output without making chips deselect. When
HOLD is the “L” level, hold operation is activated, SO becomes High-Z, SCK and SI become don’t care. While the hold operation, CS has to be retained the “L” level.

SCK
Serial Clock pin
This is a clock input pin to input/output serial data. SI is loaded synchronously to a rising
edge, SO is output synchronously to a falling edge.

SI
Serial Data Input pin
This is an input pin of serial data. This inputs op-code, address, and writing data.

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 33 MHz operation”.

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. The WP signal level shall be fixed before performing
the WRSR command, and do not change the WP signal level until the end of command sequence. WRSR

• READ
The READ command reads FRAM memory cell array data. Arbitrary 16 bits address and op-code of READ
are input to SI. The 2-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 operation”.

• WRITE
The WRITE command writes data to FRAM memory cell array. WRITE op-code, arbitrary 16 bits of address
and 8 bits of writing data are input to SI. The 2-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 33 MHz
operation”.

• FSTRD
The FSTRD command reads FRAM memory cell array data. Arbitrary 16 bits address and op-code of FSTRD
are input to SI followed by 8 bits dummy. The 2-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.

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 after 32-bit Device ID output by continuously
sending SCK clock before CS is risen. RDID command is applicable to “Up to 33 MHz operation”.

■ HOLD OPERATION
Hold status is retained without aborting a command if HOLD is the “L” level while CS is the “L” level. The
timing for starting and ending hold status depends on the SCK to be the “H” level or the “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 don’t 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.

*1 : Total number of reading and writing defines the minimum value of endurance, as an FRAM memory operates
with destructive readout mechanism.
*2 : Minimun values define retention time of the first reading/writing data right after shipment, and these values
are calculated by qualification results.
