DS28E04S-100+T

DS28E04S-100+T is a 4096bit, 1-Wire® EEPROM chip with seven address inputs. The address inputs are directly mapped into the 1-Wire 64bit device ID number to easily enable the host system to identify the physical location or functional association of the DS28E04-100 in a multidevice 1-Wire network environment. The 4096bit EEPROM array is configured as 16 pages of 32 bytes with a 32 byte scratchpad to perform write operations. EEPROM memory pages can be individually write protected or put in EPROM emulation mode, where bits can only be changed from a 1 to a 0 state. In addition to the memory, the DS28E04-100 has two general-purpose I/O ports that can be used for input or to generate level and/or pulse outputs. The DS28E04-100 communicates over the single-contact 1-Wire bus. The communication follows the standard 1-Wire protocol. Applications include central-office switches, cellular base stations, access products, optical network units, and PBXs.

• 4096 bits of EEPROM memory partitioned into 16 pages of 256bits
• Seven address inputs for physical location configuration, parasitic or VCC powered
• Two general-purpose PIO pins with pulse generation capability
• Communicates to host with a single digital signal at 15.3Kbps or 111Kbps using 1-wire protocol
• Conditional search based on PIO status or PIO activity
• Switch point hysteresis and filtering to optimize performance in the presence of noise
• Reads and writes over a wide 2.8V to 5.25V supply
• Supply current is 1mA maximum at (VCC = VPUP)
• Standby supply current is 11µA maximum at (device idle; A0 to A6 not connected)
• Operating temperature range from -40°C to +85°C, 16-pin SO package
