Overview
The FM24V10 is a family of serial F-RAM memory
devices. The memory array is logically organized as a
131,072 x 8 bit memory array and is accessed using
an
industry
standard
two-wire
(I
2C) interface.
Functional operation of the F-RAM is similar to
serial EEPROM. The major difference between the
FM24V10 and serial EEPROM is F-RAM’s superior
write performance.
Memory Architecture
When accessing the FM24V10, the user addresses
131,072 locations each with 8 data bits. These data
bits are shifted serially. The 131,072 addresses are
accessed using the two-wire protocol, which includes
a slave address (to distinguish other non-memory
devices), a page select bit, and a 2-byte address. The
17-bit address consists of a page select bit followed
by 16-bits. The complete address of 17 bits specifies
each byte address uniquely.
The access time for memory operation is essentially
zero beyond the time needed for the serial protocol.
That is, the memory is read or written at the speed of
the two-wire bus. Unlike an EEPROM, it is not
necessary to poll the device for a ready condition
since writes occur at bus speed. That is, by the time a
new bus transaction can be shifted into the part, a
write operation will be complete. This is explained in
more detail in the interface section below.
Users expect several obvious system benefits from
the FM24V10 due to its fast write cycle and high
endurance as compared with EEPROM. However
there are less obvious benefits as well. For example
in a high noise environment, the fast-write operation
is less susceptible to corruption than an EEPROM
since it is completed quickly. By contrast, an
EEPROM
requiring
milliseconds
to
write
is
vulnerable to noise during much of the cycle.
Note that it is the user’s responsibility to ensure that
VDD is within datasheet tolerances to prevent
incorrect operation.
Two-wire Interface
The FM24V10 employs a bi-directional two-wire bus
protocol using few pins or board space. Figure 2
illustrates a typical system configuration using the
FM24V10 in a microcontroller-based system. The
industry standard two-wire bus is familiar to many
users but is described in this section.
By convention, any device that is sending data onto
the bus is the transmitter while the target device for
this data is the receiver. The device that is controlling
the bus is the master. The master is responsible for
generating the clock signal for all operations. Any
device on the bus that is being controlled is a slave.
The FM24V10 always is a slave device.
The bus protocol is controlled by transition states in
the SDA and SCL signals. There are four conditions
including start, stop, data bit, or acknowledge. Figure
3 illustrates the signal conditions that specify the four
states. Detailed timing diagrams are shown in the
electrical specifications section.
