Description
2
DATA
Output
Serial data output.
4
DCLK
I/O
Clock output or clock input. Rising edges on DCLK increment the internal address
counter and present the next bit of data to the DATA pin. The counter is incremented
only if the OE input is held high, the nCS input is held low, and all configuration data
has not been transferred to the target device (otherwise, in FPGA 10K master mode,
the DCLK pin drives low).
5
WP1
Input
WRITE PROTECT (1). Used to protect portions of memory during programming. See
programming guide for details.
8
RESET/OE
Input
Output enable (active high) and reset (active low). A low logic level resets the address
counter. A high logic level enables DATA and permits the address counter to count. In
the mode, if this pin is low (reset), the internal oscillator becomes inactive and DCLK
drives low.
9
nCS
Input
Chip select input (active low). A low input allows DCLK to increment the address
counter and enables DATA to drive out. If the AT17A Series is reset with nCS low, the
device initializes as the first device in a daisy-chain. If the AT17A Series is reset with
nCS high, the device initializes as the next AT17A Series device in the chain
10
GND
Ground
A 0.2
μ
F decoupling capacitor should be placed between the V
CC
and GND pins.
12
nCASC
Output
Cascade select output (active low). This output goes low when the address counter
has reached its maximum value. In a daisy-chain of AT17A Series devices, the
nCASC pin of one device is usually connected to the nCS input pin of the next device
in the chain, which permits DCLK to clock data from the next AT17A Series device in
the chain.
A2
Input
Device selection input, A2. This is used to enable (or select) the device during
programming, when SER_EN is Low (see Programming Guide for more details)
15
READY
Output
Open collector reset state indicator. Driven Low during power-up reset, released when
power-up is complete. (Recommend a 4.7K
Pull-up on this pin if used).
18
SER_EN
Input
Serial enable is normally high during FPGA loading operations. Bringing SER_EN
Low, enables the two wire serial interface mode for programming.
