DS1321S+T&R General Description

Experience the power and efficiency of the DS1321S+T&R, a cutting-edge nonvolatile memory controller designed to meet the most demanding storage requirements. This innovative device not only monitors incoming power for any deviations but also safeguards your data by providing write protection when necessary. The lithium battery monitor ensures uninterrupted power supply to your SRAMs, guaranteeing data integrity and reliability. With support for multiple SRAMs in various memory configurations, the DS1321S+T&R offers unmatched flexibility and performance for your memory storage needs

Key Features

Converts CMOS SRAM into nonvolatile memory
Unconditionally write-protects SRAM when V_CC is out of tolerance
Automatically switches to battery backup supply when V_CC power failure occurs
Flexible memory organization
- Mode 0: 4 banks with 1 SRAM each
- Mode 1: 2 banks with 2 SRAMs each
- Mode 2: 1 bank with 4 SRAMs each
Monitors voltage of a lithium cell and provides advanced warning of impending battery failure
Signals low-battery condition on active low Battery Warning output signal
Resets processor when power failure occurs and holds processor in reset during system power-up
Optional 5% or 10% power-fail detection
16-pin PDIP, 16-pin SO and 20-pin TSSOP packages
Industrial temperature range of -40°C to +85°C
