DS1321E+ is a chip designed by Maxim Integrated, part of their family of real-time clock/calendar devices. It is an integrated IC designed to provide an easy, accurate and cost-effective solution for measuring and synchronizing time within a system. DS1321E+ features an extremely low power consumption, 6-channel time-of-day clock, four time-of-day alarms, and a 32.768kHz quartz crystal oscillator. This makes it an ideal solution for a variety of applications, including kiosks, wireless LAN systems, wireless access points, point-of-sale systems and medical monitoring systems.The DS1321E+ is a highly integrated time-of-day clock/calendar with easy synchronization of its clock registers to an external source. The device also has a back-up register function that holds the time of day information while the device is in shutdown mode. The device also provides a three-output alarm system composed of four separate alarms and a periodic interrupt.The DS1321E+ is based on Maxim Integrated’s proprietary Mixed Signal Controller™ (MSC) architecture, which is optimized for cost, low power consumption, low external component count and superior system flexibility. The MSC architecture is based on a combination of digital and analog components and incorporates several features, such as an on-chip voltage regulator and an on-chip oscillator.An important part of DS1321E+ is the Programmable Output Control Engine (POCE). This engine provides an easy and configurable means of programming outputs to control alarms and periodic interrupts. The POCE also provides an easy way of triggering an interrupt output via a high-speed pulse width modulation (PWM) signal.DS1321e+ also offers data security, with its built-in cryptographic engine. It also offers a comprehensive power management feature set, including dynamic voltage scaling, multiple power-down modes and intelligent power gating.The DS1321E+ is an ideal choice for a wide range of memory controller applications, such as digital video recorders, digital jukeboxes, server systems and digital set-top boxes. It provides an advanced architecture for timekeeping, event control and data security, reducing time-to-market for applications that rely on time-of-day synchronization and clock accuracy. The device also offers an extensive set of features, such as battery-backup, data security, flexible power management and more.In summary, the DS1321E+ is a low-cost, low-power timekeeping device that integrates a wide range of features and provides an ideal solution for memory controller applications. It has a low external component count and offers data security, battery-backup, dynamic voltage scaling, power-down modes and intelligent power gating. It is an ideal choice for applications such as digital video recorders, digital jukeboxes, server systems and digital set-top boxes. A
