Product details
Overview
7130LA20PFG8 from IDT (Integrated Device Technology) is a high-speed 1K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, 20 ns maximum read cycle time, 2V data retention capability, and TTL-compatible 5V ±10% operation. It supports independent asynchronous access from left and right ports for real-time inter-processor communication in embedded control systems.
For engineers reviewing the 7130LA20PFG8 datasheet, 7130LA20PFG8 pinout, 7130LA20PFG8 application, or 7130LA20PFG8 equivalent, key selection criteria include bus contention arbitration timing (tBAA ≤ 20 ns), low-power standby current (ISB3 = 0.2 mA typ.), battery backup support, and compatibility with IDT7140SLAVE devices in 16-bit memory expansion.
Technical Context
The 7130LA20PFG8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses for left (L) and right (R) ports. Its on-chip arbitration logic resolves simultaneous access to the same memory location using BUSY flag signaling and priority set-up time (tAPS = 5 ns).
It features open-drain BUSY outputs (BUSYL/BUSYR) requiring external pull-up resistors, INT/INTR flags for port-to-port interrupt signaling, and automatic power-down via CE control. The LA variant enables data retention at VCC = 2.0 V with ICCDR ≤ 4000 µA (military/industrial grade).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1K × 8 bits (1024 words × 8-bit data width per port) |
| Access Time (tRC) | 20 ns max - defines minimum read cycle interval for full-speed operation |
| Data Retention Voltage | 2.0 V - enables battery-backed operation without volatile data loss during main power interruption |
| Standby Current (ISB3) | 0.2 mA typical - ultra-low power consumption when both ports are disabled with CMOS-level inputs |
| Supply Voltage | 4.5 V to 5.5 V - TTL-compatible single 5V ±10% rail simplifies system power design |
| Operating Temperature | –40°C to +85°C - industrial-grade thermal range suitable for harsh embedded environments |
| Arbitration Priority Setup | tAPS = 5 ns - ensures deterministic resolution of port contention before BUSY assertion |
Pinout & Package
7130LA20PFG8 is packaged in a 64-pin STQFP (Small Thin Quad Flat Package) with 10 mm × 10 mm body and 1.4 mm height. Pin functions are validated per IDT datasheet revision Jul.12.21, Figure drw 05.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 33, 47) | Ground reference | Two dedicated ground pins reduce noise coupling and improve signal integrity across dual ports |
| VCC (Pins 32, 48) | Power supply | Dual VCC pins ensure stable core voltage delivery under high-speed switching loads |
| BUSYL / BUSYR | Arbitration status output | Open-drain flags indicating write contention on left/right port; require external pull-up for logic HIGH |
| INTL / INTR | Interrupt request output | Active-low flags signal inter-port events (e.g., flag set/clear) without software polling overhead |
| CEL / CER | Chip enable input | Independent enable controls per port allow selective activation and dynamic power gating |
| R/WL / R/WR | Read/write direction control | Asynchronous control of data flow direction per port; no clock required for operation |
| A0L–A9L / A0R–A9R | Address inputs | 10-bit address buses per port support full 1K memory addressing with no external decoding |
| I/O0L–I/O7L / I/O0R–I/O7R | Bidirectional data I/O | Separate 8-bit data buses per port eliminate multiplexing and enable true concurrent access |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C024AV-20AXC | 2K × 16 organization, 3.3V core, no battery retention, tRC = 20 ns | Requires level-shifting for 5V systems; lacks 2V data retention | Select when higher density and lower voltage operation outweigh retention needs |
| IDT7140LA20PFG8 | SLAVE-only device; no on-chip arbitration; BUSY inputs only; identical timing and retention | Must be paired with 7130LA20PFG8 in MASTER/SLAVE configuration for 16-bit expansion | Choose only as companion part to extend data bus width-cannot operate standalone as MASTER |
Compared with CY7C024AV-20AXC and IDT7140LA20PFG8, the 7130LA20PFG8 uniquely combines MASTER arbitration, 2V data retention, and industrial temperature support in a single 64-pin STQFP package-enabling self-contained dual-processor synchronization without external logic or voltage translation.

FAQ
What is the function of BUSYL and BUSYR on the 7130LA20PFG8?
BUSYL and BUSYR are open-drain arbitration status outputs on the 7130LA20PFG8. When asserted LOW, they indicate that the corresponding port (left or right) is blocked from writing due to contention with the opposite port accessing the same memory address. External pull-up resistors are required for proper logic-level operation, as specified in Note 1 of the functional block diagram.
Does the 7130LA20PFG8 support true simultaneous read operations from both ports?
Yes, the 7130LA20PFG8 supports fully asynchronous, simultaneous reads from both left and right ports without BUSY interference. BUSY signals are only asserted during write contention. Valid data appears after tAA (≤20 ns), and tOH (≥3 ns) ensures hold time for reliable latching-enabling concurrent data acquisition and processing in real-time systems.
How does the 7130LA20PFG8 achieve 2V data retention, and what is the maximum current draw in that mode?
The 7130LA20PFG8 achieves 2V data retention through optimized CMOS cell design and low-leakage fabrication. In data retention mode (VCC = 2.0 V, CE > VCC − 0.2 V), ICCDR is guaranteed ≤ 4000 µA for military/industrial grades and ≤ 1500 µA for commercial grade-verified per Table 07 in the datasheet revision Jul.12.21.
Can the 7130LA20PFG8 operate as a standalone 8-bit dual-port RAM without pairing with an IDT7140?
Yes, the 7130LA20PFG8 is fully functional as a standalone 8-bit dual-port SRAM. Its on-chip arbitration logic, BUSY outputs, and INT/INTR flags operate independently. The MASTER/SLAVE architecture is optional-used only when expanding to 16-bit or wider data paths using IDT7140SLAVE devices.
What package type does the 7130LA20PFG8 use, and are there pin-compatible alternatives in other footprints?
The 7130LA20PFG8 uses a 64-pin STQFP (Small Thin Quad Flat Package) with 10 mm × 10 mm body and 0.5 mm pitch. While IDT offered the same speed grade in 48-pin DIP, LCC, and 52-pin PLCC variants, those are not pin-compatible due to differing pin counts and signal allocations-only the STQFP variant matches the PFG8 suffix and supports all 64 defined terminals including dual VCC/GND and N/C pins.
