MK41T56 - 512 bit 64b x8 Serial Access TIMEKEEPER SRAM

General Description

The MK41T56 TIMEKEEPER® is a low power 512 bit static CMOS RAM organized as 64 words by 8 bits.

A built-in 32.768 kHz oscillator (external crystal controlled) and the first 8 bytes of the RAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format.

Key Features

  • ices that are controlled by the master are cal.

A built-in 32.768 kHz oscillator (external crystal controlled) and the first 8 bytes of the RAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. Addresses and data are transferred serially via a two-line bi-directional bus.
