STMicroelectronics has introduced a high accuracy serial realtime clock (RTC), which has an EEPROM and an embedded crystal, in a single 18-pin SOIC (small-outline integrated circuit). The new M41T56C64 helps reduce board space, increase reliability, and lower manufacturing costs.
This makes it well suited for applications requiring accurate timekeeping and non-volatile data storage. Among these applications are metering devices, medical equipment, vending machines, and point of sale (PoS) terminals.
The realtime clock (RTC) section of the device provides year, month and day data along with hours, minutes, and seconds. The EEPROM section has 8192 bytes of memory with more than 1 million erase/write cycles per byte. The RTC and the EEPROM are accessed via a two-wire I²C serial bus. The M41T56C64 also embeds the pre-calibrated 32 kHz crystal, with ±5 ppm accuracy. Embedding the crystal also provides better protection against the corrosive effects of moisture and humidity.
The M41T56C64 includes 8 bytes of BCD (binary-coded decimal) registers used for the clock/calendar functions, 56 bytes of NVRAM and 8 KB of EEPROM. When power is removed, the device automatically switches to its backup battery input and goes into a low-current mode to maximise battery life. The M41T56C64 is rated for 4,5 to 5,5 V and drawing only 450 nA (typical), the IC can accurately keep time for more than 10 years on a 48 mAh lithium coin cell, says ST.
