Product details
Overview
7052L25PFGI8 from Renesas Electronics is a high-speed 2K × 8 (16 Kbit) FourPort™ static RAM with four fully asynchronous ports, 25 ns maximum access time, industrial temperature range (–40°C to +85°C), and low-power standby consumption of 1.5 mW (typ.) per port. It enables real-time inter-processor communication in multiprocessor systems and supports simultaneous read/write access to shared memory locations without on-chip arbitration.
For engineers reviewing the 7052L25PFGI8 datasheet, 7052L25PFGI8 pinout, 7052L25PFGI8 application, or 7052L25PFGI8 equivalent, this device serves as a TTL-compatible, single 5V-supply quad-port SRAM optimized for deterministic latency, battery-backed data retention at 2V, and contention-tolerant external arbitration in embedded control and avionics subsystems.
Technical Context
The 7052L25PFGI8 implements true FourPort™ architecture with independent address, data I/O, R/W, CE, OE, and BUSY terminals per port-enabling concurrent, fully asynchronous reads/writes across all four ports. Each port features dedicated chip enable (CEP1–P4) and output enable (OEP1–P4) controls, with BUSY inputs allowing external write-inhibit signaling during port contention.
It operates on a single 5.0 V ±10% supply, delivers 25 ns max access time across commercial and industrial grades, and enters ultra-low-power standby (1.5 mW typ.) when CE is deasserted. Data retention is guaranteed down to 2 V, supporting battery backup operation with ICCDR ≤ 600 µA (com'l) or ≤ 1800 µA (industrial/military).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2K × 8 = 16 Kbit, organized as 2048 words × 8 bits per port |
| Access Time (tAA) | 25 ns max - guarantees deterministic read latency under worst-case industrial conditions |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard TTL logic rails and legacy 5V system designs |
| Standby Current (ISB) | 1.5 mW typ. per port at 5V - enables low-quiescent power in always-on subsystems |
| Data Retention Voltage | 2.0 V minimum - supports nonvolatile hold mode using coin-cell or backup rail |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade reliability in harsh environments |
| Package | 120-pin Thin Quad Flatpack (TQFP), 14 mm × 14 mm × 1.4 mm - surface-mount compatible with automated assembly |
Pinout & Package
7052L25PFGI8 is housed in a 120-pin Thin Quad Flatpack (TQFP) package with 0.4 mm lead pitch and exposed thermal pad. Pin assignments are fully defined per port (P1–P4), with dedicated address (A0–A10), bidirectional data (I/O0–I/O7), control (R/W, CE, OE, BUSY), and power (VCC, GND) terminals for each port.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0P1–A10P1 | Port 1 Address Inputs | 11-bit address bus selecting one of 2048 memory locations for Port 1 |
| I/O0P1–I/O7P1 | Port 1 Data I/O | Bidirectional 8-bit data path; high-impedance when OE = VIH or CE = VIH |
| R/WP1 | Port 1 Read/Write Control | Active-low write enable; drives I/O lines into output state when R/W = VIL and CE = VIL |
| CEP1 | Port 1 Chip Enable | Active-low port selection; disables internal circuitry and reduces current to ISB when deasserted |
| OEP1 | Port 1 Output Enable | Active-low control of output drivers; allows read data to appear on I/O lines only when asserted |
| BUSYP1 | Port 1 Write-Inhibit Input | Active-low signal blocking writes to Port 1 during external arbitration or contention detection |
Key Features
| Feature | Design Value |
|---|---|
| True FourPort™ Architecture | Four independent, fully asynchronous ports share one memory array without internal arbitration overhead |
| Simultaneous Multiport Access | Allows concurrent reads/writes to identical addresses across ports-user-managed data integrity required |
| 2V Data Retention Mode | Preserves stored data with ≤600 µA total current draw per port when VCC drops to 2.0 V |
| TTL-Compatible Interface | Direct connection to 5V logic families without level-shifting; VIH = 2.2 V min, VIL = 0.8 V max |
| Low-Power Standby | 1.5 mW typical active standby per port (vs. 7.5 mW for S-version), enabling extended battery life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT7052L25G | 108-pin PGA package; no tape-and-reel option; same speed/temp/power specs | Suitable for through-hole prototyping or legacy PGA-based systems | Select when board layout requires PGA footprint or thermal mass exceeds TQFP capability |
| CY7C1355KV18-25BGXI | 2.5V core / 3.3V I/O; 165-ball BGA; 25 ns access; 2K × 18 organization | Higher density (36 Kbit), wider data bus, lower voltage operation | Choose for new designs targeting lower power and higher throughput, accepting BGA assembly complexity |

FAQ
What is the operating temperature range for the 7052L25PFGI8?
The 7052L25PFGI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official Renesas datasheet (DSC 2674/17, July 2019 revision), and applies specifically to the PFGI and PFGI8 orderable variants packaged in the 120-pin TQFP.
Does the 7052L25PFGI8 support battery backup operation?
Yes, the 7052L25PFGI8 supports battery backup operation with guaranteed data retention at VCC = 2.0 V. The L-version low-power design draws ≤600 µA (commercial) or ≤1800 µA (industrial/military) in retention mode, as specified in Table 08a of the datasheet. This enables use with coin-cell batteries or auxiliary backup rails in mission-critical systems.
How many pins does the 7052L25PFGI8 have, and what is its package type?
The 7052L25PFGI8 uses a 120-pin Thin Quad Flatpack (TQFP) package, designated PNG120 in Renesas documentation. Its body dimensions are 14 mm × 14 mm × 1.4 mm, and it features gull-wing leads with 0.4 mm pitch. Pin configuration details-including port-specific address, I/O, and control signals-are provided in Figures 2674 drw 04 and 2674 drw 05 of the datasheet.
What is the difference between the 'S' and 'L' versions of the IDT7052 family?
The 'L' in 7052L25PFGI8 denotes the low-power variant, featuring 1.5 mW typical standby power per port versus 7.5 mW for the 'S' (standard) version. Both share identical 25 ns access time and functional pinout, but the L-version achieves lower ISB and supports 2V data retention-making it preferred for battery-backed or thermally constrained applications.
Can all four ports of the 7052L25PFGI8 access the same memory location simultaneously?
Yes, the 7052L25PFGI8's True FourPort™ architecture permits simultaneous access-including concurrent reads and writes-to the same memory address across all four ports. However, the datasheet explicitly states that data integrity during such contention is the user's responsibility; external arbitration logic must prevent conflicting writes to identical locations.
