Overview
The Renesas 7202LA50TP is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates on a unidirectional bus architecture and supports data rates up to 15MHz with a maximum access time of 50ns. The component functions at a core voltage of 5.0V and is housed in a 28-pin PDIP package. It utilizes Full and Empty flags for flow control.
Feature Summary
- Asynchronous first-in/first-out memory architecture
- Unidirectional data bus interface
- Hardware-based Full and Empty flag generation
Applications
- Data buffering between disparate clock domains
- Interface bridging for parallel communication systems
- Temporary data storage in high-speed logic circuits
Procurement Notes
Verify the obsolete status of this specific part number before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing system designs given the discontinuation. Check for moisture sensitivity handling requirements during storage and assembly processes.
Selection Notes
Select this component only if legacy support for the 28-pin PDIP package is required. Evaluate alternative surface-mount packages within the same family if new design constraints allow. Consider the 50ns access speed limitations against current system timing requirements. Verify that the 9-bit word width meets specific data path needs.
Part Context
This component belongs to the Renesas 7202L series of asynchronous FIFOs. It shares architectural similarities with other members like the 7202LA12JG but differs in package type and performance specifications. The series provides reliable dual-port memory solutions for parallel data transfer applications.
Replacement Considerations
Public confirmed substitute part numbers are not available due to the obsolete status of this specific variant. Designers should consult official documentation for recommended modern equivalents or pin-compatible alternatives within the manufacturer's current portfolio.
