CDP68HC68T1M2Z96

Overview

The CDP68HC68T1M2Z96 is a Real-Time Clock (RTC) integrated circuit manufactured by Renesas Electronics Corporation. It provides timekeeping and calendar functions alongside 32 bytes of static RAM. The device utilizes a Serial Peripheral Interface (SPI) for communication. It supports power supply voltages ranging from 3V to 6V and operates within a temperature range of -40°C to +85°C. Key features include automatic leap year calculation, alarm capabilities, and low standby current consumption. The component is housed in a 16-pin DIP package.

Feature Summary

• Integrated SPI interface for clock/calendar data access
• 32-byte static RAM for system data storage
• Automatic leap year correction and multiple alarm modes
• Low power operation with selectable crystal or line input

Applications

• Industrial control systems requiring precise time synchronization
• Data logging equipment needing non-volatile time stamps
• Embedded controllers with backup power requirements

Procurement Notes

Verify the specific suffix 'M2Z96' against official Renesas documentation to confirm tape-and-reel packaging or specific quality grade variations. Confirm RoHS compliance status as standard versions may differ. Check for end-of-life notices or obsolescence warnings prior to procurement planning.

Selection Notes

Select this component when an SPI-based RTC with integrated RAM is required. Ensure the system design accommodates the 3V-6V supply range. Verify that the available GPIO pins support the SPI protocol. Consider the 16-DIP package constraints for PCB layout if through-hole mounting is mandatory.

Part Context

This part belongs to the CDP68HC68T1 family of real-time clocks. The base model CDP68HC68T1 offers similar core functionality. Suffixes typically indicate packaging type, temperature range extensions, or environmental certifications. The T1 designation confirms the SPI interface variant.

Replacement Considerations

Direct pin-compatible replacements are limited due to the specific SPI configuration. Review the CDP68HC68T1 datasheet for functional equivalents. Alternative RTCs must match the SPI timing requirements and voltage levels. Verify memory size compatibility if the 32-byte RAM is critical.
