The real-time clock module RA8000CE that meets the AEC-Q100 automotive standard is launched, supporting the synchronous interconnection of clock signals of multiple computing chips.

With the development of new energy vehicles, the update and iteration of vehicle-mounted electronics has accelerated, raising the design requirements for electronic control systems. For different vehicle-mounted electronic components, such as ABS, TCS and other systems closely related to automobile safety, to form an integrated chassis control system, it is necessary to have a precise and reliable design of the electronic system time, so it is necessary to select a clock module that meets automotive standards to assist in the design.

For electronic systems in cars that need time synchronization, clock modules with I2C bus can be used to interconnect clock signals to support communication between multiple computing chips. Currently, EPSON has launched a real-time clock module RA8000CE that supports I2C bus. This clock module is stable and reliable, meets the AEC-Q100 automotive certification standard, and can help automotive electronics manufacturers design more modern electronic systems, which is worthy of user trust.

01 Adapt to the real-time interconnection 

Adapt to the real-time interconnection of multiple computing chip time systems, and the data is more real and effective

The core components of automobiles are gradually shifting towards intelligence and electronics. Compared with the original traditional hydraulic and mechanical systems, on-board electronics can control the overall situation and provide more operating data for drivers to understand the operating status of the car. However, the accompanying demand is that the data of different components must be strictly synchronized in time to ensure the real-time and accuracy of the data in order to maximize the safety of modern automobiles during operation. As a highly integrated chip, the I²C bus interface of RA8000CE can realize signal interconnection between computing chips. When applied to automotive electronics, it can realize the clock signal synchronization of multiple chips within a component and the signal synchronization between multiple components.

02 AEC-Q100 automotive certification

Passed AEC-Q100 automotive certification standard, can work stably at -40℃~+125℃

The RA8000CE real-time clock module is certified to the AEC-Q100 automotive standard and can maintain stable operating performance in various operating conditions during vehicle operation, ensuring stable and reliable vehicle operation and reducing the risk of failures caused by component failure. Its stable operating temperature range is -40℃~+125℃, and its maximum frequency tolerance is: ±50.0 x 10-6, meeting the high reliability requirements of modern automotive electronic systems.

03 Self-monitoring interruption

With self-monitoring interruption, auxiliary vehicle fault diagnosis function

The RA8000CE real-time clock module integrates a variety of practical functions to meet the needs of fault monitoring, maintenance and other needs. It also has a variety of processing methods to deal with power supply anomalies. It can complete the monitoring of power supply voltage drops and internal crystal oscillator abnormalities, and transmit fault signals to the upper control system through the I²C interface. Automotive electronics manufacturers can design products with more intrinsic safety characteristics based on this, protect the safety of the car in time when a car fails, and provide more accurate fault diagnosis functions during car maintenance.
