Datasheet

1. Introduction
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS
™
socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen of
the mikroBUS
™
socket. If all of the pins are
aligned correctly, push the board all
the way into the socket.

4. Essential features
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.
Before using your click board
™
, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

FRAM click
™
is an accessory board in
mikroBUS
™
form factor. It’s a compact
and easy solution for adding Ferroelectric
Random Access Memory to your design. It
features MB85RS256A 256K Ferroelectric
Random Access Memory. FRAM click
™
communicates with the target board
microcontroller via mikroBUS
™
SPI (MISO,
MOSI, SCK, CS), RST and PWM lines. The
board is designed to use 3.3V power supply
only. LED (GREEN) indicates the presence of
power supply.

FRAM click
™
with it’s MB85RS256A IC is a
256K FRAM (Ferroelectric Random Access
Memory) module which consists of 32,768
words x 8 bits. The MB85RS256A use the
ferroelectric process and silicon gate CMOS
process technologies to form nonvolatile
memory cells. This memory can be used
for 10
10
read/write operations, and does
not take long time to write data like Flash
memories or EEPROM. Maximum operating
frequency is 25MHz.
