DESCRIPTION
The Microchip Technology Inc. 24LC41 is a dual-port
128 x 8 and 512 x 8-bit Electrically Erasable PROM
(EEPROM). This device is designed for use in applica-
tions requiring storage and serial transmission of con-
figuration and control information. Three modes of
operation have been implemented:
Transmit-Only Mode for the DDC Monitor Port
Bi-directional Mode for the DDC Monitor Port
Bi-directional, industry-standard 2-wire bus for the
4K Microcontroller Access Port
Upon power-up, the DDC Monitor Port will be in the
Transmit-Only Mode, repeatedly sending a serial bit
stream of the entire memory array contents, clocked by
the VCLK/DWP pin. A valid high to low transition on the
DSCL pin will cause the device to enter the bi-direc-
tional Mode, with byte-selectable read/write capability
of the memory array. The 4K-bit microcontroller port is
completely independent of the DDC port, therefore, it
can be accessed continuously by a microcontroller
without interrupting DDC transmission activity. The
24LC41 is available in a standard 8-pin PDIP package
in both commercial and industrial temperature ranges.
