7006L12PF8

Overview

The Renesas Electronics Corporation 7006L12PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 128 kbit. It features a memory organization of 16k x 8 and supports parallel interface communication. The device has an access time of 12 ns and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 64-pin TQFP package with dimensions of 14x14 mm. The component is designed for surface mount installation and supports industrial temperature ranges.

Feature Summary

• True dual-ported memory cells allow simultaneous independent reads from the same memory location by both ports.
• On-chip hardware support for semaphore signaling enables efficient port arbitration and synchronization between processors.
• Automatic power-down feature controlled by chip enable signals allows entry into low standby power mode.
• TTL-compatible single 5V power supply operation ensures compatibility with standard logic families.

Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port RAM configurations for 16-bit or wider word systems
• Battery backup applications requiring data retention

Procurement Notes

Verify the specific suffix PF8 against official datasheets to confirm pinout and package dimensions match design requirements. Confirm RoHS compliance status and moisture sensitivity level before assembly planning. Check for any product change notices regarding lead content or material composition updates. Ensure ESD handling protocols are followed during procurement and storage.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. The 12 ns speed suits high-throughput interfaces. Verify that the 64-TQFP footprint fits the PCB layout constraints. Consider the 5V supply requirement versus system voltage levels. Evaluate the need for interrupt flags and busy signals for complex multi-processor architectures.

Part Context

The 7006 series represents a family of high-speed dual-port SRAMs designed for flexible system integration. Variants like the 7006L12PF8 offer different access speeds while maintaining the core dual-port architecture. This series supports expansion to wider bus widths through master/slave configurations, making it suitable for legacy and specialized embedded memory applications.

Replacement Considerations

Check for IDT-branded equivalents such as IDT7006L12PF8, which share identical specifications. Verify pin-to-pin compatibility with other 7006 series variants if speed or temperature ratings differ. Ensure substitute parts maintain the same 64-TQFP package and electrical characteristics.

FAQ
