Product Description

The RV-3032-C7 ultra-miniature real time clock module is available with optional AEC-Q200 qualification and provides the best combination of high accuracy and low power consumption, within a tiny 3.2 x 1.5mm package. Together with a range of unique features this RTC is perfect for applications that require "always-on" time keeping.

Designed with applications such as wearables and IoT in mind the RV-3032-C7 features superbly low current consumption of just 160nA typ. (3.0V) and features trickle charger with pump charge.

The RV-3032-C7 also features unique temperature alarm capabilities, including temperature time stamping and programmable alarm functionality. The user programmable password ensures protection of time, control and configuration registers. Also, the interrupt gated high frequency clock output function of the RV-3032-C7 can provide a microcontroller clock when needed, negating the need for a separate crystal and saving the energy used starting the oscillator to handle each interrupt.

The in-built digital temperature compensation (DTCXO) functionality ensures precision time keeping of ±2.5ppm over the entire -40 to +85ºC operating temperature range. Additional features include alarm functionality, programmable counters, selectable interrupt and clock output functions, 16 bytes User RAM and 32 bytes User EEPROM.
