DESCRIPTION
The Microchip Technology Inc. 24LCS41A 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 pin. A valid high to low transition on the DSCL
pin will cause the device to enter the transition mode,
an look for a valid control byte on the I
detects a valid control byte from the master, it will switch
to Bi-directional Mode, with byte selectable read/write
capability of the memory array using DSCL. If no con-
trol byte is received, the device will revert to the Trans-
mit-Only Mode after it received 128 consecutive VCLK

pulses while the DSCL pin is idle. The 4K-bit microcon-
troller port is completely independent of the DDC port,
therefore, it can be accessed continuously by a micro-
controller without interrupting DDC transmission activ-
ity. The 24LCS41A is available in a standard 8-pin PDIP
package in both commercial and industrial temperature
ranges.
