NM93C86A 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 16-
bit format is selected. There are 7 instructions implemented on the
NM93C86A 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.

Deion:
The Microchip Technology Inc. 93XX86A/B/C devices
are 16K bit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93XX86C are dependent upon external logic
levels driving the ORG pin to set word size. The
93XX86A devices provide dedicated 8-bit memory
organization, while the 93XX86B devices provide
dedicated 16-bit memory organization. A Program
Enable (PE) pin allows the user to write-protect the
entire memory array. Advanced CMOS technology
makes these devices ideal for low-power, nonvolatile
memory applications. The entire 93XX Series is
available in standard packages including 8-lead PDIP
and SOIC, and advanced packaging including 8-lead
MSOP, 6-lead SOT-23, 8-lead 2×3 DFN/TDFN and 8-
lead TSSOP. All packages are Pb-free (Matte Tin)
finish.
Вот тут действительно нет выбора битности с индексом «А». Значит оптимально ставить только такие?
