Pin Description
Address. The 13 address lines select one of 8,192 bytes in the FRAM
array. The address value will be latched on the falling edge of /CE.
Data. 8-bit bi-directional data bus for accessing the FRAM array.
Chip Enable. /CE selects the device when low. The falling edge of /CE
causes the address to be latched internally. Address changes that
occur after /CE goes low will be ignored until the next falling edge
occurs.
Output Enable. When /OE is low the FM1608 drives the data bus when
valid data is available. Taking /OE high causes the DQ pins to be tri-
stated.
Write Enable. Taking /WE low causes the FM1608 to write the contents
of the data bus to the address location latched by the falling edge of
/CE.
Supply Voltage. 5V
