AT24C512C-SSHM-T

Memory IC Overview

The AT24C512C-SSHM-T is a 512-Kbit (65,536 x 8) serial EEPROM manufactured by Microchip Technology. It features an I²C-compatible two-wire interface supporting 100 kHz standard mode and 400 kHz fast mode at supply voltages between 1.7V and 3.6V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-lead SOIC package. Key electrical characteristics include a maximum access time of 900 ns, self-timed write cycles up to 5 ms, and low standby current consumption.

Memory IC Feature Summary

• I²C-compatible two-wire serial interface with Schmitt triggers and filtered inputs for noise suppression
• Hardware data protection via the Write-Protect pin inhibiting all write operations when high
• 128-byte page write mode allowing partial page writes to improve efficiency
• High reliability with one million write cycle endurance and 100-year data retention

Memory IC Applications

• Industrial systems requiring low-power non-volatile storage
• Commercial applications needing reliable parameter storage
• Battery-powered devices utilizing low-voltage operation modes
• Multi-device bus configurations addressing up to eight units on a single bus

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the 'SSH' designation corresponds to the 8-lead SOIC package variant. Ensure the voltage grade matches the required 1.7V to 3.6V operational range for the target application environment. Cross-reference the datasheet revision DS20006161B for accurate timing parameters.

Memory IC Selection Notes

Select this component for designs requiring robust I²C communication with hardware write protection capabilities. The 8-lead SOIC package suits surface-mount assembly processes. Consider the 128-byte page write structure for optimizing data throughput during bulk programming operations. Verify that the system power supply remains stable within the specified operating range to prevent unintended reset events.

Memory IC Part Context

This part belongs to the AT24C512C family of serial EEPROMs from Microchip Technology. The family offers various package options including SOIJ, TSSOP, UDFN, WLCSP, and VFBGA. All variants share the same internal memory organization and I²C protocol support, differing primarily in physical footprint and pin compatibility for PCB layout flexibility.

Memory IC Replacement Considerations

Compatible substitutes within the same package and specification include other AT24C512C variants such as AT24C512C-SSHD-T or AT24C512C-SSHMEU-T. Verify that any replacement maintains the 1.7V minimum operating voltage and 400 kHz interface speed requirements.
