Real Time Clocks ICs

M48T58-70PC1 Description

The M48T58-70PC1 from STMicroelectronics is a high-performance Real-Time Clock (RTC) and Calendar IC designed for precision timekeeping in embedded systems. Housed in a 28-pin DIP package, this parallel-interface device operates within a 4.75V to 5.5V supply range and is optimized for 0°C to 70°C industrial environments. As part of the Timekeeper® series, it integrates a clock/calendar with 24-hour time format (HH:MM:SS) and leap year compensation, ensuring long-term accuracy. With a maximum timekeeping current of 3mA, it balances low power consumption with reliability. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.

M48T58-70PC1 Features

• Parallel Interface: Enables direct communication with microcontrollers or processors for seamless integration.
• Leap Year Compensation: Automatically adjusts for leap years, reducing firmware complexity.
• Wide Voltage Range (4.75V–5.5V): Compatible with standard 5V systems, ensuring versatility.
• Low Timekeeping Current (3mA max): Ideal for battery-backed or power-sensitive applications.
• Through-Hole Mounting (28DIP): Simplifies prototyping and legacy system designs.
• Industrial Temperature Range (0°C to 70°C): Suitable for harsh environments.
• Non-Volatile Storage: Retains time and calendar data during power loss.

M48T58-70PC1 Applications

This RTC is ideal for systems requiring accurate timekeeping with minimal host intervention, such as:
