Memory IC datasheet and documents for AT45DB642D-CNU
Memory IC Overview
The AT45DB642D-CNU is a 64-megabit DataFlash memory device operating on a single 2.7V to 3.6V supply. It features a dual-interface architecture supporting RapidS serial interface with up to 66MHz clock frequency and Rapid8 8-bit interface with up to 50MHz clock frequency. The memory array consists of 8,192 pages, each configured for either 1,024 bytes or 1,056 bytes. Two SRAM data buffers match the page size, enabling concurrent data reception and reprogramming. The device supports continuous read capabilities across the entire array.
Memory IC Feature Summary
- Dual-interface architecture allowing simultaneous connection of dedicated serial and 8-bit ports
- User-configurable page sizes of 1,024 or 1,056 bytes with factory pre-configuration options
- Two SRAM data buffers facilitating data reception during main memory reprogramming
- Continuous read capability through the entire array without delays at page boundaries
Memory IC Applications
- Digital voice storage applications
- Image storage applications
- Program code storage applications
- Data storage applications requiring low-pin count interfaces
Memory IC Procurement Notes
Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range and interface requirements align with system specifications. Ensure compatibility with existing SPI or 8-bit bus architectures before procurement.
Memory IC Selection Notes
Select this component when both high-speed serial access and parallel 8-bit access are required within a single device. Consider the dual-interface capability if the design utilizes separate processors for different tasks. Evaluate the power consumption characteristics against system battery life requirements.
Memory IC Part Context
This part belongs to the AT45DB642D DataFlash family, designed for sequential access memory needs. It integrates advanced buffer management and flexible erase options to support efficient data logging and code shadowing in embedded systems.
