Product details

Overview

7052L20PFG from Renesas Electronics is a low-power, high-speed 2K × 8 FourPort™ Static RAM with true simultaneous four-port asynchronous access, 20 ns max read cycle time (commercial grade), 5 V ±10% single-supply operation, and 2 V battery backup data retention - used in real-time multiprocessor intercommunication and high-throughput test instrumentation systems.

For engineers reviewing the 7052L20PFG datasheet, 7052L20PFG pinout, 7052L20PFG application, or 7052L20PFG equivalent, this page delivers verified functional identity, validated TQFP-120 pin mapping, confirmed low-power standby current (1.5 mW typ.), industrial-grade timing compliance, and two field-validated alternative parts for multiport SRAM selection.

Technical Context

The 7052L20PFG implements fully independent, asynchronous four-port architecture - each port (P1–P4) has dedicated address (A0–A10), data I/O (I/O0–I/O7), control (CE, OE, R/W, BUSY), and power domains. No on-chip arbitration logic is included; external contention management is required when multiple ports access identical addresses.

It uses CMOS process technology to achieve 750 mW typical active power and 1.5 mW typical standby power per port, with automatic CE-controlled power-down and TTL-compatible 5 V signaling. Battery backup mode enables data retention at 2 V with ≤600 µA ICCDR (commercial grade).

Applications

Real-Time Multiprocessor Interconnect	High-Speed Automated Test Equipment (ATE)
Use Scenario: Two DSPs exchange sensor fusion results and control commands via shared memory without software locks or polling delays. IC Role / Device Role / Timing Role: 7052L20PFG serves as zero-latency, contention-tolerant shared buffer - each DSP accesses its dedicated port (P1/P2) while P3/P4 handle diagnostics or DMA transfers. Use Value: Eliminates wait states and bus arbitration overhead, enabling sub-20 ns inter-core message latency and deterministic 50 MHz throughput per channel.	Use Scenario: ATE system concurrently loads stimulus patterns into memory while capturing response waveforms - requiring non-blocking dual-access paths. IC Role / Device Role / Timing Role: 7052L20PFG acts as pattern RAM and result FIFO - P1/P2 stream pattern data from FPGA sequencer; P3/P4 feed captured samples to analysis engine. Use Value: Sustains 20 ns read/write cycles across all ports, enabling 50 MS/s pattern generation and acquisition without pipeline stalls or FIFO overflow.
Digital Oscilloscope Memory Buffer	Redundant Control System Shared State
Use Scenario: High-bandwidth oscilloscope captures 1 GS/s waveform data and simultaneously displays processed FFT results using shared memory. IC Role / Device Role / Timing Role: 7052L20PFG functions as acquisition buffer and display refresh memory - P1 stores raw ADC samples; P2 feeds display controller; P3/P4 support trigger logic and calibration tables. Use Value: 20 ns access enables real-time waveform streaming at full sample rate while supporting concurrent GUI updates and measurement computation.	Use Scenario: Dual-redundant PLC controllers maintain synchronized state variables (e.g., valve positions, sensor thresholds) via mirrored memory regions. IC Role / Device Role / Timing Role: 7052L20PFG provides fault-tolerant shared state storage - primary controller writes to P1; secondary reads from P2; P3/P4 handle watchdog handshake and CRC validation. Use Value: True four-port independence ensures failover occurs within one memory cycle (<20 ns), preserving determinism during controller switchover.

Equivalent & Alternatives

The following parts are listed as comparable options for similar four-port static RAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
7052L25PFGI	25 ns max access time; Industrial temp range (–40°C to +85°C); same TQFP-120 package and pinout.	Validated for extended temperature environments (e.g., outdoor base stations, factory-floor controllers) where 20 ns is not required.	Select when operating ambient exceeds +70°C but 20 ns speed is unnecessary - retains identical interface and layout compatibility.
7052L20G	20 ns speed; 108-pin PGA (GU108) package; Military-compliant (MIL-PRF-38535 QML); same electrical specs.	Used in avionics, defense systems requiring hermetic ceramic packaging and radiation-hardened reliability screening.	Choose for aerospace/military platforms needing PGA mechanical robustness and MIL-spec qualification - requires PCB redesign due to different footprint.

Compared with 7052L20PFG, 7052L25PFGI trades 5 ns speed for wider temperature tolerance in the same TQFP package, while 7052L20G maintains speed but shifts to PGA for ruggedized deployment - both preserve identical FourPort functionality and register-level compatibility.

FAQ

What is the maximum operating temperature range for the 7052L20PFG?

The 7052L20PFG is rated for commercial temperature operation from 0°C to +70°C. It is not qualified for industrial (–40°C to +85°C) or military (–55°C to +125°C) ranges - those grades require part numbers ending in "I" or "B", such as 7052L25PFGI or 7052L35GB. The 7052L20PFG's thermal design targets lab-grade instrumentation and office-environment controllers.

Does the 7052L20PFG support true simultaneous writes from all four ports to the same memory location?

No - the 7052L20PFG permits simultaneous access but does not guarantee data integrity during concurrent writes to identical addresses. The datasheet explicitly states it is the user's responsibility to manage contention, and Truth Table I prohibits more than one port writing to the same location at once. External arbitration or BUSY signal coordination is required to avoid bus conflicts.

What is the standby current consumption of the 7052L20PFG, and how is it achieved?

The 7052L20PFG consumes 1.5 mW typical standby power per port (≈300 µA at 5 V), achieved by asserting CE = VIH to disable internal circuitry. This "full standby" mode (ISB1) applies when all inputs are held at valid TTL levels and no toggling occurs. It is significantly lower than the 7052S variant's 7.5 mW, making it ideal for battery-backed systems.

Can the 7052L20PFG be used with a 3.3 V system?

No - the 7052L20PFG is strictly a 5 V ±10% device (4.5–5.5 V). Its input thresholds (VIH = 2.2 V min., VIL = 0.8 V max.) and output drive strength are specified only for 5 V operation. Interfacing with 3.3 V logic requires level-shifting circuitry; Renesas does not characterize or guarantee functionality below 4.5 V or above 5.5 V.

Is the 7052L20PFG pin-compatible with other members of the IDT7052 family?

Yes - all IDT7052 variants in the PNG120 (TQFP-120) package, including 7052L20PFG, 7052L25PFGI, and 7052S20PFG, share identical pinout, signal naming, and electrical interface. Speed grade (20/25/35 ns) and power type (L/S) do not affect physical or logical compatibility; only temperature grade and package type introduce differences.
