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
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

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
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.
