DS2423
4kbit 1-Wire
RAM with Counter
to 142kbits per second
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 with strict 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

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.

DESCRIPTION
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
Pin Configurations appear at end of data sheet.
Functional Diagrams continued at end of data sheet.
