概要
Description
Introduction to DS1230Y-100
- The DS1230Y-100 is part of Dallas/Maxim’s DS1230 family of nonvolatile RAM (NVSRAM). It combines a RAM array with embedded nonvolatile storage to preserve data when power is removed, while allowing SRAM-like fast access during operation.
- Benefits: fast reads/writes like SRAM, plus data retention without power for backup, enabling instant-on operation and protection of critical data (config data, logs, caches, firmware parameters).
- The Y-100 suffix denotes a specific density/packaging option within the DS1230 line; exact capacity, timing, and interface are variant-dependent and should be confirmed in the datasheet.
- Typical uses: embedded systems needing reliable data storage across power cycles, data buffering, event logging, and look-up tables that must survive power loss.
- Usage notes: choose the appropriate interface/organization, treat writes like SRAM, and rely on internal nonvolatile writes for power-down safety.
- For precise electrical specs, timing, endurance, and packaging, consult the DS1230Y-100 datasheet.

Features
DS1230Y-100 is a Dallas/Maxim timekeeper RAM device. Key features (concise):
- Real-time clock/calendar with seconds, minutes, hours, day/date, month, year (leap-year aware)
- 32.768 kHz timebase input for accurate timekeeping
- Battery-backed NVSRAM (non-volatile RAM) for data retention
- VBAT backup input to preserve time and memory during power loss
- Serial interface (SPI-compatible) for read/write access to time registers and memory
- 8-pin package (DIP/SOIC) with standard pinout
- Power-fail detection and data integrity during transitions
- Low-power operation in battery-backed mode
Note: Specifics (memory size, exact interface details, operating voltage/temperature ranges) are in the datasheet; confirm for your exact revision.
