Микросхемы и комплектующие M48T18-100PC1

Часы реального времени , NVSRAM с учетом времени, параллельный интерфейс, 4.5В до 5.5В, DIP-28

The M48T18-100PC1 is a TIMEKEEPER® Non-volatile Static RAM and Real-time Clock which is pin and functional compatible with the DS1642. This is a non-volatile pin and function equivalent to any JEDEC standard 8K x 8 SRAM. It also easily fits into many ROM, EPROM and EEPROM sockets providing the non-volatility of PROMs without any requirement for special write timing or limitations on the number of write that can be performed.

• Integrated ultralow power SRAM, real-time clock, power-fail control circuit and battery
• BYTEWIDE™RAM-like clock access
• BCD coded year, month, day, date, hours, minutes and seconds
• Typical clock accuracy of ±1 minute a month at 25°C
• Software controlled clock calibration for high accuracy applications
• Automatic power-fail chip deselect and WRITE protection
• 100ns Speed
