詳細說明
The DS2423 1-Wire® RAM with Counters is a fully static, read/write memory for battery operation in a low-cost, six-lead TSOC, surface-mount package. The memory is organized as 16 pages of 256 bits each. In addition, the device has four counters, two of them with external trigger inputs called A and B. Each of the counters is associated with a memory page. A counter without external trigger input increments each time data is written to the page it is associated with (write cycle counter). The counters triggered by inputs A and B, respectively, increment with every low-going pulse on their input. All counters are read only. They are automatically cleared to 0 when the battery is connected.FEATURES 4096 bits of SRAM Four 32-bit, read-only counters Active-low external trigger inputs for two of the counters with on-chip debouncing compatible with reed and Wiegand switches 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 Memory partitioned into 16 256-bit pages in for packetizing data 256-bit scratchpad withstrict read/write protocols ensures integrity of data transfer On-chip 16-bit CRC generator for safeguarding data transfers Built-in multidrop controller ensures compatibility with other MicroLAN products Directly connects to a single port pin of a microprocessor and communicates at up to 16.3kbits per second Overdrive mode boosts communication speed to 142kbits per second 8-bit family code specifies device communication requirements to reader Presence detector acknowledges when reader first applies voltage Compact, low cost 6-pin TSOC surface mount package Reads, writes and counts over a wide voltage range of 2.8V to 5.5V from -40°C to +85°C
