Pin Description
A(16:0)
Input
Address inputs: The 17 address lines select one of 131,072 words in the F-RAM array. The
lowest two address lines A(1:0) may be used for page mode read and write operations.
/CE
Input
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.
/WE
Input
Write Enable: A write cycle begins when /WE is asserted. The rising edge causes the
FM21L16 to write the data on the DQ bus to the F-RAM array. The falling edge of /WE
latches a new column address for page mode write cycles.
/OE
Input
Output Enable: When /OE is low, the FM21L16 drives the data bus when valid read data is
available. Deasserting /OE high tri-states the DQ pins.
/ZZ
Input
Sleep: When /ZZ is low, the device enters a low power sleep mode for the lowest supply
current condition. Since this input is logically AND’d with /CE, /ZZ must be high for normal
read/write operation. If unused, tie /ZZ to VDD.
DQ(15:0)
I/O
Data: 16-bit bi-directional data bus for accessing the F-RAM array.
/UB
Input
Upper Byte Select: Enables DQ(15:8) pins during reads and writes. These pins are hi-Z if /UB
is high. If the user does not perform byte writes and the device is not configured as a 256Kx8,
the /UB and /LB pins may be tied to ground.
/LB
Input
Lower Byte Select: Enables DQ(7:0) pins during reads and writes. These pins are hi-Z if /LB
is high. If the user does not perform byte writes and the device is not configured as a 256Kx8,
the /UB and /LB pins may be tied to ground.
