The RV-1805-C3 is no longer recommended for new designs, please consider the RV-3028-C7 as a low power solution for new projects.

The RV-2123-C2 real time clock (RTC) module offers the engineer SPI bus interface with low supply voltage options within a miniature surface mount package. A time-saving all-in-one solution with our lowest power consumption for an SPI bus module, this uncompensated solution also features excellent shock and vibration resistance and optional AEC-Q200 qualification.

Due to technology improvements the RV-3029-C2 is no longer recommended for new designs but is suitable as a drop in replacement for existing designs within a 5.0 x 3.2mm footprint which require I²C bus 2-wire serial interface and frequency stability over temperature ranges as wide as -40 to +125ºC. For new designs that require extended temperature ranges please consider the smaller and more competitive RV-3129-C3 or RV-8803-C7 for designs where power consumption is paramount. This product was previously named RV3029C2.

The RV-3029-C3 is no longer recommended for new designs but is suitable as a drop in replacement for existing designs which require a miniature 3.7 x 2.5mm footprint. The RV-3029-C3 offers excellent time accuracy of ±3ppm (0.26s/day drift) and is temperature compensated, allowing for outstanding ±8ppm stability over extended operating temperature range of -40 to +125ºC. The RV-3029-C3 with I²C bus interface also features great shock and vibration resistance and is available with AEC-Q200 qualification (and full PPAP documentation) on request. This product was previously named RV3029C3.

Due to technology improvements the RV-3049-C2, SPI bus RTC is no longer recommended for new designs but is suitable as a drop in replacement for existing designs within a 5.0 x 3.2mm footprint and which require SPI bus and frequency stability over extended temperature ranges as wide as -40 to +125ºC. For new designs that require temperature compensation over extended temperature ranges please consider the smaller and more competitive RV-3149-C3. This product was previously named RV3049C2.

The RV-3049-C3 is no longer recommended for new designs but is suitable as a drop in replacement and features superb timing stability, temperature compensation and SPI bus interface in a miniature 3.7 x 2.5mm surface mount package. Wide operating temperature ranges of -40 to +125ºC are available as is AEC-Q200 qualification and full PPAP documentation on request.

Within a miniature 3.7 x 2.5mm footprint the RV-3129-C3 offers excellent time accuracy and is temperature compensated, allowing for outstanding ±8ppm stability over extended operating temperature range of -40 to +125ºC. The RV-3129-C3 with I²C bus interface also features great shock and vibration resistance and is available with AEC-Q200 qualification (and full PPAP documentation) on request.

The RV-3149-C3 features superb timing stability, temperature compensation and SPI bus interface in a miniature 3.7 x 2.5mm surface mount package with side castellations. Wide operating temperature ranges of -40 to +125ºC are available as is AEC-Q200 qualification and full PPAP documentation on request.

The RV-4162-C7 ultra-miniature RTC module is perfect for high volume applications where you need an all-in-one solution to help with space saving and procurement costs. The tiny 3.2 x 1.5mm footprint enables additional design space and, along with wide operating voltage range and good stability at room temperature, the RV-4162-C7 also features I²C bus interface, standard clock and calendar functionality, alarm setting and a watchdog function. This product was previously named RV4162C7.

The RV-8063-C7 has low current consumption of just 190nA typical and is operable over wide voltage range of 0.9V to 5.5V making it a highly cost effective all-in-one real time clock solution,

This RTC module also features a miniature surface mount package of 3.2 x 1.5mm, excellent real time clock functionality including alarm setting, timer, SPI interface, and automatic leap year calculation from 2000 to 2099 in addition to standard clock and calendar functionality including internal power-on reset (POR). 

Ideal for engineers who require low power at supply voltages down to 1.2V, the RV-8532-C3 with I²C bus interface consumes current of only 130nA in time-keeping mode. Encased within a miniature 3.7 x 2.5mm footprint package, the RV-8523-C3 also features good shock and vibration performance and is available with AEC-Q200 qualification and full PPAP documentation on request. This product was previously named RV8523C3.

Due to technology improvements the RV-8564-C2 is no longer recommended for new designs but is suitable as a drop in replacement for existing designs within a 5.0 x 3.2mm footprint which require I²C bus 2-wire serial interface and current consumption of up to 250nA. For new designs that require low power consumption please consider the smaller and more competitive RV-1805-C3 or RV-4162-C7 for designs where highly competitive pricing is paramount.

Due to technology improvements the RV-8564-C3 with I²C bus interface is no longer recommended for new designs but is fully available for existing design-ins.
