512 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground
. Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures absolute traceability because no two parts are alike
. Built-in multidrop controller ensures compatibility with other MicroLAN products
. EPROM partitioned into two 256-bit pages for randomly accessing packetized data
. 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
. Directly connects to a single port pin of a microprocessor and communicates at up to 16.3 kbps
. 8-bit family code specifies DS2501 communications requirements to reader

6 MHz Crystal Oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. This frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators, but other piezoelectric materials including polycrystalline ceramics are used in similar circuits.

The DS1307 serial real-time clock (RTC) is a lowpower, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.

The IC CD4026 is an IC which can perform the function of both a counter as well a 7-segment Driver. One single IC can be used to count form zero (0) to nine (9) directly on a Common Cathode type 7-segment display. The count can be increased by simply giving a high clock pulse; also more than one digit (0-9) can be created by cascading more than one CD4026 IC. So if you have a 7-segment (CC) display on which you have to display numbers that are being counted based on some condition then this IC will be a perfect choice.
