Renesas 7006L20PFI8

Overview

7006L20PFI8 from IDT is a high-speed 16K × 8 (128 Kbit) true dual-port static RAM with independent left/right ports, 20 ns maximum access time (industrial grade), 5 V ±10% single supply, and on-chip semaphore/arbitration logic for inter-port synchronization. It enables simultaneous read access to the same memory location and supports master/slave cascading for 16-bit+ bus expansion in real-time embedded control systems.

For engineers reviewing the 7006L20PFI8 datasheet, 7006L20PFI8 pinout, 7006L20PFI8 application, or 7006L20PFI8 equivalent, key selection criteria include industrial-temperature operation (–40°C to +85°C), low standby current (1 µA typ.), BUSY/INT/SEM flag support, TQFP-64 packaging, and compatibility with asynchronous dual-processor or FPGA-to-ASIC bridging architectures.

Technical Context

The 7006L20PFI8 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; symmetric right-port signals). Its on-chip arbitration logic resolves contention via BUSY flag assertion (output when M/S = H, input when M/S = L) and supports semaphore signaling across eight flags addressed by A0–A2.

It features TTL-compatible inputs, push-pull BUSY/INT outputs, battery-backed data retention at 2 V (100–4000 µA ICCDR), and automatic power-down via CE-controlled standby modes - including full CMOS-level standby (ISB3 = 0.2 mA typ. for L version). The device operates without external logic in MASTER/SLAVE configurations for error-free 16-bit word systems.

Key Specifications

Pinout & Package

7006L20PFI8 is housed in a 64-pin thin quad flatpack (TQFP) package, designated PNG64, with 0.5 mm lead pitch and exposed thermal pad. All VCC pins require decoupling; all GND pins must be connected to ground plane for signal integrity and EMI control.

FAQ

What is the operating temperature range for the 7006L20PFI8?

7006L20PFI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the Absolute Maximum Ratings and DC Electrical Characteristics tables of the official IDT datasheet (document 2739, revision Jan.30.20), making it suitable for deployment in programmable logic controllers, motor drives, and outdoor industrial equipment where ambient thermal extremes are expected.

Does the 7006L20PFI8 support battery backup operation?

Yes, the 7006L20PFI8 supports battery backup with data retention down to 2.0 V (VDR), drawing only 100–4000 µA depending on grade and temperature. This capability is explicitly specified in the Data Retention Characteristics table (Table 09) and validated for the "L" (low-power) variant - confirming reliable state preservation during main power loss in safety-critical or energy-harvesting applications.

How does the BUSY flag function in master vs. slave configuration on the 7006L20PFI8?

When M/S = H (master), BUSYL/BUSYR are push-pull outputs that assert during port contention; when M/S = L (slave), they become inputs used to receive BUSY signals from a master device. This dual-role behavior is defined in the Pin Names table (Table 01) and Timing Waveform figures (e.g., DRW 13–14), enabling flexible hierarchical arbitration in multi-device memory systems without external logic.

What package type is used for the 7006L20PFI8?

7006L20PFI8 uses a 64-pin thin quad flatpack (TQFP) package, identified as PNG64 in IDT documentation. Its mechanical dimensions are 14 mm × 14 mm × 1.4 mm with 0.5 mm lead pitch, and pin configuration matches the top-view diagram in Drawing 03 - confirmed across Functional Block Diagram, Pin Configurations, and Package Notes sections of the datasheet.

Can the 7006L20PFI8 be used in a 16-bit data bus configuration?

Yes, the 7006L20PFI8 supports 16-bit expansion via MASTER/SLAVE cascading using the M/S pin. Two devices can be configured - one as master (M/S = H), one as slave (M/S = L) - to form a 16K × 16 memory without external glue logic, as described in the Description section and enabled by the BUSY input/output duality and on-chip arbitration logic.
