PowerCap

DESCRIPTION The DS1743 is a full-function, year-2000-compliant (Y2KC), real-time clock/calendar (RTC) and 8k x 8 nonvolatile static RAM. User access to all registers within the DS1743 is accomplished with a bytewide interface as shown in Figure 1. The RTC information and control bits reside in

PowerCap

DS9034PC PowerCap是一款为非易失(NV) SRAM提供的锂电池电源帽，基于Dallas Semiconductor直接表面贴装PowerCap模块封装。PowerCap模块焊接、清理后，DS9034PC PowerCap可以直接固定在基座上，构成完整的NV SRAM模块。PowerCap从形状上可以避免不正确的安装，通过设计即使在剧烈冲击与振动的情况下仍能保持与主模块基座的机械和电气接触。DS9034PC可以轻松地进行拆卸，只需将普通的螺丝刀插入其可分离部位、轻轻向上向外撬，就可以将PowerCap从模块基座上卸下来。 ·为PowerCap模块(PCM)封装的NV SRAM提供10年备用电池电源\n·直接固定在表面贴装PowerCap模块基座上，构成完整的NV SRAM模块\n·模块基座焊接后安装，使锂电池免受回流焊的高温\n·即使在剧烈冲击与振动情况下仍能保持与模块基座的机械与电气连接\n·可分离特性，使用普通螺丝刀就可以方便的拆卸\n·定期更换可以无限延长NV SRAM模块的寿命\n·与以下PowerCap模块基座兼容：\n·DS1230YP/ABP/WP \n·DS1245YP/ABP/WP \n·DS1250YP/ABP/WP \n·DS1330YP/ABP/WP \n·DS1345YP/ABP/WP;

256k Nonvolatile SRAM

DESCRIPTION The DS1230 256k Nonvolatile SRAMs are 262,144-bit, fully static, nonvolatile SRAMs organized as 32,768 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors VCC for an out-of-tolerance condition. When such a conditio

RAMified Watchdog Timekeeper

DESCRIPTION The DS1386 is a nonvolatile static RAM with a full-function Real Time Clock (RTC), alarm, watchdog timer, and interval timer which are all accessible in a byte-wide format. The DS1386 contains a lithium energy source and a quartz crystal, which eliminates the need for any external cir

256K NV Y2KC Timekeeping RAM

DESCRIPTION The DS1554 is a full function, year 2000-compliant (Y2KC), real-time clock/calendar (RTC) with a RTC alarm, watchdog timer, power-on reset, battery monitor, and 32k x 8 non-volatile static RAM. User access to all registers within the DS1554 is accomplished with a bytewide interface as

Low-Cost, Ultra-Small, Single/Dual/Quad Single-Supply Comparators

General Description The MAX9030/MAX9031/MAX9032/MAX9034 single/ dual/quad comparators are optimized for single-supply applications from +2.5V to +5.5V but can also be operated from dual supplies. These comparators have a 188ns propagation delay and consume 35µA of supply current per comparator
