Product details
Overview
IDT7006L20PFI from Integrated Device Technology (IDT) is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 20 ns maximum read cycle time (tRC), industrial temperature range (–40°C to +85°C), and 5 V ±10% single-supply operation. It supports simultaneous reads of the same memory location and integrates on-chip semaphore logic and BUSY arbitration for real-time inter-processor communication in embedded control systems.
For engineers reviewing the IDT7006L20PFI datasheet, IDT7006L20PFI pinout, IDT7006L20PFI application, or IDT7006L20PFI equivalent, key selection criteria include dual-port timing compatibility, M/S master/slave cascading capability, battery-backed data retention at 2 V, TTL-level I/O compatibility, and 64-pin TQFP package footprint for space-constrained industrial PCBs.
Technical Context
The IDT7006L20PFI implements fully asynchronous dual-port architecture with separate address, data, and control buses per port (A0L–A13L/I/O0L–I/O7L/R/WL/CEL/OEL/BUSYL/SEML/INTL on left; A0R–A13R/I/O0R–I/O7R/R/WR/CER/OER/BUSYR/SEMR/INTR on right). Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports semaphore signaling across ports using A0–A2 address bits.
It features automatic power-down via CE control, delivering 700 mW typical active power and only 1 mW typical standby power. The device operates in industrial temperature range and retains data down to 2 V supply-enabling seamless battery backup during main power loss without external circuitry.

FAQ
What is the maximum operating speed of the IDT7006L20PFI?
The IDT7006L20PFI has a maximum read cycle time (tRC) of 20 ns, supporting up to 50 MHz sustained memory access per port. This speed applies across the full industrial temperature range (–40°C to +85°C) and is guaranteed under VCC = 5.0 V ±10%. The device also supports 20 ns write cycle timing, ensuring balanced read/write performance in real-time dual-processor systems.
Does the IDT7006L20PFI support battery backup operation?
Yes, the IDT7006L20PFI supports battery backup operation with guaranteed data retention at VCC = 2.0 V. In data retention mode (CE > VHC, inputs held > VHC or < VLC), it draws ≤4000 µA (military/industrial grade) while preserving all 128 Kbit contents. This feature enables seamless state preservation during main power interruption without external hold circuitry.
How does the BUSY arbitration logic work in the IDT7006L20PFI?
The IDT7006L20PFI uses hardware BUSY arbitration to resolve port contention: when both ports attempt access to the same memory location, the M/S-configured master asserts BUSY within 20 ns (tBAA), blocking the slave port's write until BUSY deasserts. The tBDD parameter (≤30 ns) defines the delay from BUSY deassertion to valid read data-ensuring deterministic conflict resolution without software intervention.
Can the IDT7006L20PFI be used in a 16-bit data bus configuration?
Yes, the IDT7006L20PFI supports 16-bit (or wider) data bus expansion via Master/Slave cascading. When two devices are connected with M/S = H (master) and M/S = L (slave), the master's BUSY output drives the slave's BUSY input, enabling coordinated access across both 8-bit ports. This eliminates external glue logic and maintains full 20 ns speed in expanded configurations.
What package type is used for the IDT7006L20PFI?
The IDT7006L20PFI is packaged in a 64-pin Thin Quad Flatpack (TQFP), designated PNG64, with dimensions 14 mm × 14 mm × 1.4 mm and 0.5 mm lead pitch. This RoHS-compliant, green-part-qualified package supports automated SMT assembly and provides thermal and electrical performance suited for industrial PCB layouts with tight spacing constraints.
