Memory IC datasheet and documents for AT93C46A-10PI-1.8
Memory IC Overview
The AT93C46A-10PI-1.8 is a 1K-bit (64 x 16) serial electrically erasable programmable read-only memory (EEPROM). It features a three-wire serial interface with a maximum clock rate of 2 MHz at 5V and operates within a supply voltage range of 1.8V to 5.5V. The device utilizes self-timed write cycles with a maximum duration of 10 ms. It supports industrial temperature ranges from -40°C to +85°C and is housed in an 8-lead PDIP package.
Memory IC Feature Summary
- Supports low-voltage operation down to 1.8V for power-sensitive applications
- Provides high reliability with endurance of one million write cycles
- Features a simple three-wire serial interface for efficient data communication
- Ensures long-term data retention capabilities
Memory IC Applications
- Industrial control systems requiring non-volatile storage
- Commercial applications needing low-power EEPROM solutions
- Embedded systems utilizing serial communication protocols
Memory IC Procurement Notes
Verify the specific ordering suffix '-1.8' confirms the 1.8V to 5.5V operating voltage range, as distinct from the '-2.7' variant. Confirm the 'I' designation indicates the industrial temperature grade (-40°C to +85°C). Ensure the 'PI' suffix matches the required 8-lead PDIP package type for your board layout.
Memory IC Selection Notes
Select this component when a 1K-bit capacity with 16-bit word organization is required. Choose the '-1.8' version if the system operates below 2.7V. Consider the three-wire interface compatibility with the host processor. Verify that the 10ms write cycle time fits the application's timing constraints.
