Technical details and manufacturing context for Data Register

Definition

A data register is a fundamental component in I/O peripheral systems that serves as a temporary storage location for data being transferred between the peripheral device and the main processing unit. It acts as a buffer to synchronize data flow, handle speed mismatches, and ensure reliable communication by holding data until it can be processed or transmitted. This directory entry covers data registers used in computer, electronic, and optical product manufacturing, typically fabricated from silicon. The register's data capacity ranges from 16 to 64 KB, data width from 8 to 32 bits, and access time from 10 to 70 ns. Operating voltage is 3.3 to 5.0 V, with power consumption between 0.5 and 2.0 W. Operating temperature range is -40 to 85 °C, storage temperature -55 to 125 °C, and relative humidity 5 to 95% non-condensing. Ingress protection is rated IP40 to IP65. Data retention is 10 to 20 years, endurance 100,000 to 1,000,000 write/erase cycles, and weight 5 to 20 g. These values are reference ranges; actual specifications must be confirmed with the manufacturer for the specific model and application. The register operates by receiving data from either the peripheral device or the main system, storing it in flip-flop or latch circuits, and releasing it when triggered by control signals. It includes input/output control logic, clock synchronization, and sometimes error-checking mechanisms. When selecting a data register, verify that the data capacity, width, access time, voltage, power, temperature, humidity, protection, retention, endurance, and weight meet the system requirements. Confirm compliance with relevant standards such as IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-78, IEC 60529, and JESD22-A117, as applicable. Always consult the legal manufacturer or supplier for model-specific values and standards.

Working Principle

Data registers operate by receiving data from either the peripheral device or the main system, storing it in flip-flop or latch circuits, and then releasing it when triggered by control signals. They typically include input/output control logic, clock synchronization, and sometimes error-checking mechanisms to ensure data integrity during transfer operations. The register acts as a temporary buffer, holding data until the receiving side is ready, thereby synchronizing data flow and accommodating speed mismatches. Control signals determine when data is written to or read from the register, and the clock ensures proper timing. Error-checking mechanisms, if present, verify data integrity during transfer. The register's capacity and width determine how much data can be buffered at once, while access time affects transfer speed. Operating voltage and power consumption must match the system's power supply and thermal budget. Environmental limits, such as temperature and humidity, define the safe operating and storage conditions. The register's endurance and data retention specify its expected lifespan under normal use. Proper operation requires that all electrical and environmental parameters stay within the specified ranges to avoid data corruption or device failure.

Frequently Asked Questions

What is the typical data capacity range for a data register?

According to the directory, data registers typically have a data capacity ranging from 16 to 64 KB. This determines the amount of data that can be buffered during I/O operations. However, the exact capacity depends on the specific model and application, so you should confirm with the manufacturer.

What operating voltage and power consumption are common for data registers?

The directory lists operating voltage as 3.3 to 5.0 V and power consumption as 0.5 to 2.0 W. These values are reference ranges; actual specifications may vary. Lower power consumption is critical for portable and embedded applications, so verify the exact values for your chosen model.

What environmental conditions can a data register withstand?

Data registers typically operate in temperatures from -40 to 85 °C and can be stored from -55 to 125 °C. Relative humidity should be 5 to 95% non-condensing. Ingress protection ranges from IP40 to IP65, depending on the model. Always check the manufacturer's datasheet for exact limits.

How long does a data register retain data and what is its endurance?

Data retention is typically 10 to 20 years under normal operating conditions, and endurance is 100,000 to 1,000,000 write/erase cycles. These figures are based on standards like JESD22-A117. For specific models, consult the manufacturer to confirm these values.
