概述

Description

DS1230Y-100 is a Dallas Semiconductor (now Maxim) device that combines nonvolatile SRAM with a real-time clock (RTC). It provides persistent memory that remains intact during power loss thanks to a backup supply (VBAT) and an on‑chip RTC for timekeeping. The part is accessed via a simple serial interface (3‑wire/Microwire‑like), enabling standard read/write operations and providing features like write protection and power‑fail awareness. The “Y” and “-100” denote a specific family variant and speed/characteristic options for this part, with different memory sizes available within the DS1230 family. Typical applications include embedded systems that need time-stamped data, configuration or logs that must survive outages without a separate battery-backed RAM or external RTC. For exact memory capacity, voltage ranges, timing, and pinout, consult the DS1230Y-100 datasheet from Maxim/Dallas.

Features

DS1230Y-100 is a Dallas/Maxim nonvolatile SRAM with battery backup. Key features:
- Battery-backed NVSRAM: data retained on power loss
- Fast access: 100 ns read/write access time
- Memory density: 8K × 8 (64 Kb) SRAM array (NV)
- Power: operates from main supply with VBAT backup
- Power-fail data retention: automatic switchover to backup power
- Write-protect and simple interface (8-pin package)
- Temperature range: suitable for industrial use (-40°C to +85°C)
- Long data retention on backup power and high endurance (no wear-out like EEPROM)

Package

8-pin DIP (DIP-8) package.

Pinout

Pin count: 8 pins (available in 8-pin DIP/SOIC packages).
Function: The DS1230Y-100 is a microprocessor supervisory/reset and watchdog IC. It monitors VCC and provides power‑on reset and brown‑out protection, contains a watchdog timer to detect/recover from software lockups, and offers manual reset/enable/reset output signals to reliably reset and hold a microcontroller during power transients or firmware failures.

Manufacturer

Manufacturer: Dallas Semiconductor (DS).
Dallas Semiconductor was a semiconductor company that designed and produced memory and mixed-signal integrated circuits (e.g., NVSRAM, RTCs). It was acquired by Maxim Integrated in 2001, and Maxim is now part of Analog Devices.

Application

DS1230Y-100 is a battery-backed NVSRAM with an integrated real-time clock. Common applications:
- Data logging with time stamping
- Event/fault recording
- Embedded controllers with power-loss protection
- Industrial automation and process control
- Automotive/telecom equipment for persistent config/data
- Medical devices needing persistent data
- POS, kiosks, digital cameras, and other RTC-enabled electronics
