MCP795W11T-I/ST

MCP795W11T-I/ST is a clock/timing device designed for the Real Time Clock market. It is a monolithic CMOS integrated circuit designed to allow the user to convert a digital standard to a physical format and vice versa. The functionality of the device is focused on controlling and tracking time. This can be accomplished by converting the Readable Standard Time (RST) from a base second/minute/hour/etc. to a physical form such as a pulse or waveform.

The MCP795W11T-I/ST consists of a highly accurate clock module and an asynchronous synchronous input device. It has an Internal Crystal Oscillator with an operating frequency of 32.768kHz. The output signal of the device is controlled by an integrated 32-bit programmable divider, which can divide the input rate by up to 2^32. Outputs are provided in various formats, including pulse and waveform. The device also has a programmable ON/OFF timer and alarm.

MCP795W11T-I/ST also includes a pin-programmable feature known as time zone shift which allows the user to select the time zone or offset up to 8 times to avoid time drift from the actual time. This device also supports two types of alarms, a pulsed output and a serial port interrupt. The pulsed output can produce a TTL pulse when the alarm is set and can be programmed to a specific period, allowing for an alert at the end of the specified time period. The serial port interrupt produces an interrupt signal which can be used to generate an interrupt request at a specified interval and can also be used to achieve Pulse Width Modulation (PWM).

The MCP795W11T-I/ST also has an internal power supply supervisor that supports battery backup operations and provides a continuous power supply to the device during extended standby periods. It also includes a Battery Input pin which can be used to externally power the device when the internal power supply is not available.

MCP795W11T-I/ST can be used in applications such as vehicle monitoring and tracking, security systems, network timing applications, industrial, military, and aerospace applications, and other embedded systems. In these applications, the device can be used to provide a time reference, can be used to measure time periods, and can be used to provide a time trigger for control systems.

The MCP795W11T-I/ST has a wide operating temperature range and a low power consumption, making it ideal for a variety of applications. The device is capable of operation from -40°C to +85°C and is rated for operation at a power consumption of 7.5mA (typical) at 25°C and 10mA (maximum) at 85°C.

In summary, MCP795W11T-I/ST is a real time clock device suitable for a wide variety of applications. It is highly accurate and has a wide operating temperature range and low power consumption, making it ideal for most time tracking applications. By using the features of the device such as pulse and waveform output, it can accurately convert an input rate into a physical format and permit time zone shift to avoid time drift. Furthermore, the device includes a battery input and can be used as a back-up supply during extended stand-by periods.
