AK6010A Datasheet, PDF (5/15 Pages) Asahi Kasei Microsystems – I2C bus 32K / 64Kbit Serial CMOS EEPROM

ASAHI KASEI
[AK6010A/12A]
Pin Descriptions
SCL (Serial Clock)
The SCL input is used to clock all data into and out of the device.
SDA (Serial Data)
The SDA is a bidirectional pin used to transfer data into and out of the device.
It is an open drain output and may be wire-ORed with any number of open drain or open
collector outputs.
S0, S1, S2 (Device Address)
The S0, S1 and S2 are device address inputs that are used to set three bits of the slave
address.
A total of eight devices can be connected to the same bus.
WC (Write Control)
If the WC is High level, WRITE operations onto the upper quarter of the memory (AK6010A:
C00 to FFF(Hex), AK6012A: 1800 to 1FFF(Hex)) will not be executed. If the WC is Low level,
the AK6010A/12A will be enabled to perform WRITE operation.
As the WC is internally pulled down to GND, the AK6010A/12A will be enabled to perform
WRITE operation if the WC is left floating.
WC must not change from the start condition input to the stop condition input.
VCC (Power Supply)
GND (Ground)
