FM93C86A
16K-Bit Serial CMOS EEPROM
(MICROWIRE™ Synchronous Bus)

General Description

FM93C86A is a 16,384-bit CMOS non-volatile EEPROM orga­nized as 1024 x 16-bit array. This device features MICROWIRE
interface which is a 4-wire serial bus with chipselect (CS), clock
(SK), data input (DI) and data output (DO) signals. This interface
is compatible to many of standard Microcontrollers and Micropro­cessors. This device offers a pin (ORG), using which, the user can
select the format of the data (16-bit or 8-bit). If ORG is tied to GND,
then 8-bit format is selected, while if ORG is tied to VCC, then 16­bit format is selected. There are 7 instructions implemented on the
FM93C86A for various Read, Write, Erase, and Write Enable/
Disable operations. This device is fabricated using Fairchild
Semiconductor floating-gate CMOS process for high reliability,
high endurance and low power consumption.

“LZ” and “L” versions of FM93C86A offer very low standby current
making them suitable for low power applications. This device is
offered in both SO and DIP packages.

NOTE: Pins designated as "NC" are typically unbonded pins. However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care
should be taken that the voltage applied on these pins does not exceed the VCC applied to the device. This will ensure proper operation.

Note 1: Stress above those listed under “Absolute Maximum Ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Typical leakage values are in the 20nA range.

Note 3: ORG pin may draw >1µA when in x8 mode due to the internal pull-up transistor.

Note 4: The shortest allowable SK clock period = 1/f

SK

(as shown under the fSK parameter). Maximum
SK clock speed (minimum SK period) is determined by the interaction of several AC parameters stated
in the datasheet. Within this SK period, both t

SKH

and t

SKL

limits must be observed. Therefore, it is not

allowable to set 1/fSK = t

SKHminimum

+ t

SKLminimum

for shorter SK cycle time operation.

Note 5: CS (Chip Select) must be brought low (to V

IL

) for an interval of tCS in order to reset all internal
device registers (device reset) prior to beginning another opcode cycle. (This is shown in the opcode
diagram on the following page.)

Note 6: This parameter is periodically sampled and not 100% tested.
