Introducing the BQ3285ES-B2 Real-Time Clock from Texas Instruments

The BQ3285ES-B2 is a sophisticated real-time clock module designed by the renowned semiconductor company, Texas Instruments. This integrated circuit is engineered to provide precise time and date tracking, with the added functionality of a battery-backed non-volatile (NV) SRAM. This makes it an ideal choice for a wide array of applications that require reliable timekeeping even in the event of a power failure.

At the heart of the BQ3285ES-B2 is a quartz crystal that oscillates at 32.768 kHz, which ensures high accuracy in timekeeping. The module is capable of tracking time with a granularity of seconds, minutes, hours, day, date, month, and year, with automatic leap year compensation valid up to the year 2100. This level of detail is essential for applications that demand precise timestamping and scheduling.

One of the standout features of the BQ3285ES-B2 is its integrated battery-backed NV SRAM. This allows the device to maintain time, date, and stored data even when the primary power source is lost. The NV SRAM is user-accessible, providing a convenient way to store critical data that must be preserved during power outages.

The BQ3285ES-B2 is designed for versatility and can be easily integrated into a variety of systems thanks to its simple I/O interface. It is compatible with microcontrollers and microprocessors through a parallel interface, allowing for straightforward communication and integration into existing designs. Additionally, the module comes in a DIP (Dual In-line Package) form factor, making it suitable for through-hole mounting, which is favorable for prototyping and production in various electronic devices.

With its robust feature set, the BQ3285ES-B2 from Texas Instruments is an excellent choice for applications such as embedded systems, industrial controls, point-of-sale terminals, network infrastructure, and other systems that require an accurate real-time clock with battery backup capabilities. Its reliability and ease of use make it a go-to solution for designers looking to enhance their systems with accurate timekeeping and data retention features.
