AT93C46A-10TU-2.7

Memory IC Overview

The AT93C46A-10TU-2.7 is a 1K-bit (64 x 16) serial EEPROM manufactured by Microchip Technology, housed in an 8-lead TSSOP package. It operates within a supply voltage range of 2.7V to 5.5V and supports a clock frequency up to 2 MHz at 5V. The device features a three-wire serial interface with self-timed write cycles of 10 ms maximum. It provides high reliability with 1 million write cycle endurance and 100-year data retention, functioning reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Three-wire serial interface for efficient communication
• Self-timed erase and write cycles without separate erase requirement
• High endurance and long-term data retention capabilities

Memory IC Applications

• Industrial applications requiring low-power operation
• Commercial systems needing non-volatile storage
• Automotive grade electronic components

Memory IC Procurement Notes

Verify the specific ordering suffix 'TU' corresponds to the lead-free/halogen-free variant in the official Microchip ordering guide. Confirm that the '-2.7' designation matches the required 2.7V to 5.5V operating voltage range for your system design. Ensure the TSSOP package dimensions align with your PCB footprint requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 1K-bit capacity is sufficient for storing configuration data or calibration values. Choose the TSSOP package for space-constrained surface-mount designs. Verify that the host processor can support the three-wire Microwire protocol and that the 2 MHz clock rate meets the system's timing constraints.

Memory IC Part Context

This part belongs to the AT93C46A series of serial EEPROMs from Microchip Technology. The series offers various voltage options and package types, including PDIP, SOIC, and TSSOP. The AT93C46A specifically provides 64 words of 16-bit memory, distinguishing it from other capacities in the broader 93XX family.

Memory IC Replacement Considerations

Check for AT93C46A-10SU-2.7 if a SOIC package is acceptable instead of TSSOP. Consider AT93C46A-10PI-2.7 for through-hole mounting needs. Verify pinout compatibility and electrical specifications before substituting with other 93C46 variants.
