Renesas 7006L20PF

Overview

7006L20PF from IDT is a high-speed 16K × 8 dual-port static RAM with true asynchronous dual-port architecture, 20 ns maximum access time (industrial grade), 1 mW typical standby power, and TTL-compatible 5 V ±10% operation. It enables simultaneous independent read/write access from left and right ports and supports master/slave cascading for 16-bit+ data bus expansion in real-time inter-processor communication systems.

For engineers reviewing the 7006L20PF datasheet, 7006L20PF pinout, 7006L20PF application, or 7006L20PF equivalent, this page delivers verified timing parameters (tRC = 20 ns, tAA = 20 ns), BUSY/INT/SEM arbitration logic behavior, industrial temperature range (–40°C to +85°C), TQFP-64 package mapping, and direct alternative part comparisons grounded in IDT's official documentation.

Technical Context

The 7006L20PF implements full on-chip hardware semaphore signaling using A0–A2 address lines to control eight shared flags, with dedicated SEMR/SEML inputs and INTL/INTR outputs. Its port arbitration logic resolves contention via BUSYL/BUSYR flags-asserted on address match (M/S = VIH) or accepted as input (M/S = VIL)-enabling deterministic priority resolution without external logic.

It operates fully asynchronously per port: CE, R/W, and OE control each port independently; reads and writes require no clock; and power-down is triggered by CE high on either port. The device retains data at 2 V (V_DR = 2.0 V) with ICCDR ≤ 4000 µA (military/industrial), supporting battery backup operation in fail-safe embedded systems.

FAQ

What is the maximum operating temperature range for the 7006L20PF?

The 7006L20PF is rated for industrial temperature operation from –40°C to +85°C, with all electrical specifications-including 20 ns access time and 1 mW standby current-guaranteed across this full range without derating. This qualification makes it suitable for deployment in factory automation, transportation, and outdoor embedded systems where ambient thermal stress is significant.

Does the 7006L20PF support true simultaneous read operations from both ports?

Yes, the 7006L20PF features true dual-ported memory cells that allow simultaneous reads of the same memory location from left and right ports without contention or arbitration delay. This capability is intrinsic to its silicon design and is explicitly confirmed in the datasheet's "Features" section and functional block diagram-enabling deterministic latency in lock-step processing applications.

How does the BUSY flag function in master versus slave configuration on the 7006L20PF?

When M/S = VIH, the 7006L20PF operates as master: BUSYL and BUSYR are push-pull outputs that assert during address/contention arbitration. When M/S = VIL, it operates as slave: BUSYL and BUSYR become inputs, accepting BUSY signals from a master device. This dual-mode behavior is defined in Note 1 of the Functional Block Diagram and enables flexible cascaded topologies without external logic.

What is the minimum supply voltage required to retain data in the 7006L20PF?

The 7006L20PF guarantees data retention down to 2.0 V (V_DR = 2.0 V), as specified in Table 9 ("Data Retention Characteristics"). At this voltage, ICCDR remains ≤ 4000 µA under military/industrial conditions-enabling reliable battery backup operation during main power failure, brownouts, or controlled shutdown sequences in safety-critical systems.

Which package type does the 7006L20PF use, and what are its mechanical dimensions?

The 7006L20PF uses a 64-pin thin quad flatpack (TQFP) package, designated PNG64 in IDT documentation. Its body measures 14 mm × 14 mm × 1.4 mm, with gull-wing leads and standard JEDEC MO-220 footprint. Pin 1 is marked by a dot or beveled corner, and all VCC/GND pins are distributed per the "Pin Configurations" diagram on page 3 of the datasheet.
