Description

The DS28EC20+ is a 20Kb 1-wire EEPROM in 3 pin TO-92 package. A 20480bit, 1-wire EEPROM organized as 80 memory pages of 256bits each. An additional page is set aside for control functions. Data is written to a 32byte scratchpad, verified and then copied to EEPROM memory. As a special feature, blocks of eight memory pages can be write protected or put in EPROM emulation mode where bits can only be changed from a 1state to a 0state. It communicates over single conductor 1-wire bus. Device has its own unalterable and unique 64bit ROM registration number. The registration number is used to address device in a multidrop 1-wire net environment. It is used in device authentication, IEEE 1451.4 sensor TEDS, Ink/toner cartridges, medical sensors, PCB identification and wireless base stations.
Supply voltage range is 4.75V to 5.25V
Operating temperature range from -40°C to 85°C
Read and write access highly backward compatible to legacy devices (e.g. DS2433)
256bit scratchpad with strict read/write protocols ensures integrity of data transfer
200K write/erase cycle endurance at +25°C
Switchpoint hysteresis and filtering to optimize performance in the presence of noise
Communicates to host at 15.4Kbps or 90Kbps using 1-wire protocol
IEC 1000-4-2 level 4 ESD protection (±8kV contact, ±15kV air, typical) for I/O pin
