Pin Description
Address inputs: The 18 address lines select one of 262,144 words in the FRAM array.
The lowest two address lines A(1:0) may be used for page mode read and write
operations.
Chip Enable input: The device is selected and a new memory access begins when /CE is
low and /ZZ is high. The entire address is latched internally on the falling edge of /CE.
Subsequent changes to the A(1:0) address inputs allow page mode operation when /CE
is low.
Write Enable: A write cycle begins when /WE is asserted. The rising edge causes the
FM22L16 to write the data on the DQ bus to the FRAM array. The falling edge of /WE
latches a new column address for fast page mode write cycles.
Output Enable: When /OE is low, the FM22L16 drives the data bus when valid read
data is available. De-asserting /OE high tri-states the DQ pins.
Sleep: When /ZZ is low, the device enters a low power sleep mode for the lowest
current condition. Since this input is logically AND’d with /CE, /ZZ must be high for
normal read/write operation.
Data: 16-bit bi-directional data bus for accessing the FRAM array.
Upper Byte Select: Enables DQ(15:8) pins during reads and writes. These pins are hi-Z
if /UB is high.
Lower Byte Select: Enables DQ(7:0) pins during reads and writes. These pins are hi-Z
if /LB is high.
Supply Voltage: 3.3V
