FAQ
What is the maximum clock frequency supported by the AT93C86-10SC-2.7?
The AT93C86-10SC-2.7 supports a maximum serial clock frequency of 10 MHz under standard operating conditions (VCC ≥ 2.7 V). This timing allows efficient configuration reads during system boot while maintaining compatibility with legacy Microwire controllers that operate below 10 MHz.
Does the AT93C86-10SC-2.7 support both 8-bit and 16-bit memory organization?
Yes, the AT93C86-10SC-2.7 supports dual organization modes: 2,048 × 8 or 1,024 × 16. The ORG pin determines configuration - high for 16-bit mode, low for 8-bit mode. This flexibility allows the same AT93C86-10SC-2.7 to serve multiple microcontroller architectures without redesign.
How does hardware write protection work on the AT93C86-10SC-2.7?
Hardware write protection on the AT93C86-10SC-2.7 is controlled by the WP (Write Protect) pin. When WP is pulled low, all write and erase operations are disabled regardless of software commands. This feature prevents unintended modifications during power-up, brown-out, or EMI events - a critical safeguard in the AT93C86-10SC-2.7's industrial deployments.
What is the data retention specification for the AT93C86-10SC-2.7?
The AT93C86-10SC-2.7 guarantees 100 years of data retention at +25°C ambient temperature, per Microchip's characterization testing. Retention decreases predictably at elevated temperatures - e.g., ~30 years at +85°C - enabling accurate lifetime modeling for products using the AT93C86-10SC-2.7 in harsh environments.
Is the AT93C86-10SC-2.7 RoHS compliant and lead-free?
Yes, the AT93C86-10SC-2.7 is RoHS compliant and manufactured with lead-free terminations. The SOIC-8 package meets JEDEC standard MS-012, and the device carries the "Pb-Free" marking per Microchip's packaging documentation - confirming full compliance for the AT93C86-10SC-2.7 in environmentally regulated markets.
