AT24C08A-10PC-2.7

Memory IC Overview

The AT24C08A-10PC-2.7 is an 8K (1024 x 8) serial electrically erasable and programmable read-only memory (EEPROM) manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum clock frequency of 100 kHz at this voltage level. The device utilizes a 2-wire serial interface for bidirectional data transfer and features Schmitt triggers with filtered inputs for noise suppression. It includes a write protect pin for hardware data protection, allowing normal read/write operations when grounded and protecting the full array when connected to VCC. The component is housed in an 8-pin PDIP package and is designed for industrial applications requiring low power consumption.

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage range and package type. Confirm the temperature grade aligns with the intended operational environment. Ensure the device address pins are correctly configured for the target system topology. Check for any automotive or extended temperature variants if operating conditions exceed standard industrial limits.

Memory IC Selection Notes

Select this component for applications requiring 8Kbit capacity with robust noise immunity. The 2.7V variant is suitable for systems where the supply voltage may drop below standard 5V levels but remains above 2.7V. Consider the 8-pin PDIP package for through-hole mounting requirements. Evaluate the 100 kHz speed limit against the system's data throughput needs.
