Description
The Microchip Technology Inc. 24LC16B is a 16 Kbit
Electrically Erasable PROM. The device is organized
as eight blocks of 256 x 8-bit memory with a 2-wire
serial interface. Low-voltage design permits operation
down to 2.5V with standby and active currents of only
1 µA and 1 mA, respectively. The 24LC16B also has a
page write capability for up to 16 bytes of data. The
24LC16B is available in the standard 8-pin SOIC and
5-lead SOT-23 packages.

2.1 Serial Address/Data Input/Output
(SDA)
SDA is a bidirectional pin used to transfer addresses
and data into and out of the device. Since it is an
open-drain terminal, the SDA bus requires a pull-up
resistor to VCC (typical 10 kfor 100 kHz, 2 kfor
400 kHz).
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
reserved for indicating Start and Stop conditions.
2.2 Serial Clock (SCL)
The SCL input is used to synchronize the data transfer
to and from the device.
2.3 Write-Protect (WP)
The WP pin must be connected to either VSS or VCC.
If tied to VSS, normal memory operation is enabled
(read/write the entire memory 000-7FF).
If tied to VCC, write operations are inhibited. The entire
memory will be write-protected. Read operations are
not affected.
2.4 A0, A1, A2
The A0, A1 and A2 pins are not used by the 24LC16B.
They may be left floating or tied to either VSS or VCC.
