Type
The CLK and ADV# inputs can be tied to V
nous or page mode. WAIT will be asserted but should be ignored during asynchronous and
page mode operations.
16Mb: 1 Meg x 16 Async/Page/Burst CellularRAM 1.0 Memory
Address inputs: Inputs for addresses during READ and WRITE operations.
Addresses are internally latched during READ and WRITE cycles. The address lines
are also used to define the value to be loaded into the bus configuration register
or the refresh configuration register.
Clock: Synchronizes the memory to the system operating frequency during
synchronous operations. When configured for synchronous operation, the address
is latched on the first rising CLK edge when ADV# is active. CLK is static LOW or
HIGH during asynchronous access READ and WRITE operations and during PAGE
READ ACCESS operations.
Address valid: Indicates that a valid address is present on the address inputs.
Addresses can be latched on the rising edge of ADV# during asynchronous READ
and WRITE operations. ADV# can be held LOW during asynchronous READ and
WRITE operations.
Configuration register enable: When CRE is HIGH, WRITE operations load the
refresh configuration register or bus configuration register.
Chip enable: Activates the device when LOW. When CE# is HIGH, the device is
disabled and goes into standby or deep power-down mode.
Output enable: Enables the output buffers when LOW. When OE# is HIGH, the
output buffers are disabled.
Write enable: Determines if a given cycle is a WRITE cycle. If WE# is LOW, the cycle
is a WRITE to either a configuration register or to the memory array.
Lower byte enable: DQ[7:0].
Upper byte enable: DQ[15:8].
Data inputs/outputs.
Wait: Provides data-valid feedback during burst READ and WRITE operations. The
signal is gated by CE#. WAIT is used to arbitrate collisions between REFRESH and
READ/WRITE operations. WAIT is asserted when a burst crosses a row boundary.
WAIT is also used to mask the delay associated with opening a new internal page.
WAIT is asserted and should be ignored during asynchronous and page mode
operations. WAIT is High-Z when CE# is HIGH.
Not internally connected.
Device power supply (1.7–1.95V): Power supply for device core operation.
I/O power supply (1.7–3.6V): Power supply for input/output buffers.
