M48T35AV-10MH6E

Real Time Clock Overview

The M48T35AV-10MH6E is a 256 Kbit (32K x 8) non-volatile static RAM integrated with a real-time clock and power-fail control circuit. Manufactured by STMicroelectronics, it operates at a maximum access time of 100 ns in a 28-lead SOIC package. The device features automatic power-fail chip deselect and write protection for the M48Z35AV variant. It provides JEDEC standard pin and function compatibility while offering battery-backed memory solutions via compatible SNAPHAT housings.

Real Time Clock Feature Summary

• Integrated ultra-low power SRAM, real-time clock, and power-fail control circuit
• Automatic power-fail chip deselect and write protection
• Battery low flag (BOK) output
• JEDEC standard 32K x 8 SRAM pin and function compatibility

Real Time Clock Applications

• Data logging systems requiring non-volatile storage
• Real-time clock applications with battery backup
• Industrial control systems needing power-fail protection

Real Time Clock Procurement Notes

Verify that the SNAPHAT battery housing is ordered separately as it is not included with the SOIC component. Confirm the specific suffix requirements for your application, noting that the 'V' designation indicates a power-fail deselect voltage range of 2.7V to 3.0V. Ensure compatibility with the intended battery part numbers such as M4T28-BR12SH1 or M4T32-BR12SH1.

Real Time Clock Selection Notes

Select this component when a combined SRAM and RTC solution is required in a surface-mount package. The M48T35AV variant is suitable for applications requiring lower power-fail detection thresholds compared to the AY version. Consider the separate SNAPHAT housing options based on required battery capacity and operating temperature ranges.

Real Time Clock Part Context

This part belongs to the M48T35 Timekeeper family, which combines non-volatile memory with timekeeping functions. The M48T35AV-10MH6E utilizes a 28-lead SOIC body designed to accept a top-mounted SNAPHAT housing containing the lithium battery and quartz crystal, enabling a compact, integrated backup solution.

Real Time Clock Replacement Considerations

The M48T35AV-10MH1F is a similar 28-lead SOIC option within the same family. Verify if the specific power-fail voltage characteristics and battery housing compatibility meet the design requirements before substitution.
