製品の詳細
- 65536 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground
- Overdrive mode boosts communication speed to 142 kbits per second
- EPROM partitioned into two hundred and 56 256-bit pages for randomly accessing packetized data records
- Each memory page can be permanently write-protected to prevent tampering
- Device is an "add only" memory where additional data can be programmed into EPROM without disturbing existing data
- Architecture allows software to patch data by superseding an old page in favor of a newly programmed page
- Reduces control, address, data, power, and programming signals to a single data pin
- 8-bit family code specifies DS1986 communications requirements to reader
- Reads over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C; programs at 11.5V to 12.0V from -40°C to +85°C
