Overview
The Renesas 7007L12JI8 is a dual-port static random-access memory (SRAM) device with a storage capacity of 256 kbit, organized as 32k x 8 bits. It features an asynchronous parallel interface with a maximum access time of 12 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-PLCC package measuring 24.21x24.21 mm. It functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Provides true dual-port architecture enabling simultaneous independent read and write operations on separate ports.
- Utilizes asynchronous operation to eliminate bus contention during concurrent data transfers.
- Supports high-speed data handling through rapid access times suitable for demanding processing tasks.
Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in microcontroller designs
- Real-time data logging applications
Procurement Notes
Verify the specific suffix JI8 against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Check for recent product change notifications regarding packaging or material composition updates. Confirm availability status directly with authorized distributors as this component may be subject to limited supply or end-of-life restrictions.
Selection Notes
Select this component when simultaneous bidirectional data access is required without external arbitration logic. Ensure the design accommodates the 68-pin PLCC footprint and 5V logic levels. Verify that the system power supply remains stable within the 4.5V to 5.5V range to maintain signal integrity and prevent data corruption during operation.
Part Context
This part belongs to the Renesas 7007L series of dual-port SRAMs, designed for applications requiring fast, non-blocking memory access. The series offers various speed grades and package options to suit different performance and form factor requirements in industrial and commercial electronics.
Replacement Considerations
Cross-reference with IDT7007L12JI8 for potential pin-compatible alternatives from Integrated Device Technology. Verify electrical parameters and package dimensions before substitution.
