24LCS22A2Kb I2C Serial EEPROM for DDC1™/DDC2™ Monitor Identification | Memory | 2 | Active | The Microchip Technology Inc. 24LCS22A is a 256 x 8-bit
dual-mode Electrically Erasable PROM (EEPROM). This
device is designed for use in applications requiring
storage and serial transmission of configuration and
control information. Two modes of operation have been
implemented: Transmit-Only mode (1 Kbit) and
Bidirectional mode (2 Kbit). Upon power-up, the device
will be in the Transmit-Only mode, sending a serial bit
stream of the memory array from 00h to 7Fh, clocked by
the VCLK pin. A valid high-to-low transition on the SCL pin
will cause the device to enter the Transition mode, and
look for a valid control byte on the I2C™Compatible bus. If it detects a
valid control byte from the master, it will switch into
Bidirectional mode, with byte selectable read/write
capability of the entire 2K memory array using SCL. If no
control byte is received, the device will revert to the Transmit-Only mode after it receives 128 consecutive VCLK
pulses while the SCL pin is idle. The 24LCS22A is available
in standard 8-pin PDIP and SOIC packages. The
24LCS22A features a flexible write-protect pin which is
enabled by writing to address 7Fh (usually the checksum
in VESA® applications. |

25AA02E482Kb 1.8V SPI Serial EEPROM with Pre-Programmed EUI-48™ MAC ID | Memory | 2 | Active | The Microchip Technology Inc. 25AA02E48 is a 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25AA02E48 is available in the standard 8-lead SOIC and 6-lead SOT-23 packages. |
