X20C16
PIN DESCRIPTIONS
Addresses (A0–A10)
The Address inputs select an 8-bit memory location
during a read or write operation.
Chip Enable (CE)
The Chip Enable input must be LOW to enable all read/
write operations. When CE is HIGH, power consumption
is reduced.
Output Enable (OE)
The Output Enable input controls the data output buffers
and is used to initiate read and recall operations. Output
Enable LOW disables a store operation regardless of
the state of CE, WE, or NE.
Data In/Data Out (I/O0–I/O7)
Data is written to or read from the X20C16 through the
I/O pins. The I/O pins are placed in the high impedance
state when either CE or OE is HIGH or when NE is LOW.
Write Enable (WE)
The Write Enable input controls the writing of data to the
static RAM.
FUNCTIONAL DIAGRAM
Nonvolatile Enable (NE)
The Nonvolatile Enable input controls the recall function
to the E2PROM array.
AUTOSTORE Output (AS)
AS is an open drain output which, when asserted indi-
cates VCC has fallen below the AUTOSTORE threshold
(VASTH). AS may be wire-ORed with multiple open drain
outputs and used as an interrupt input to a microcontroller.
