Product details
Overview
7132LA100PDG from IDT is a high-speed 2K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, BUSY output flag (open-drain), 100 ns max read/write cycle time, 5 V ±10% supply, and industrial temperature range (–40°C to +85°C). It enables full-speed 16-bit-or-wider memory expansion when paired with IDT7142 SLAVE devices in real-time embedded control systems.
For engineers reviewing the 7132LA100PDG datasheet, 7132LA100PDG pinout, 7132LA100PDG application, or 7132LA100PDG equivalent, this page delivers verified timing parameters, BUSY arbitration behavior, low-power standby current (1 µA typical full-standby), battery backup data retention at 2 V, and package-specific pin validation for the 48-pin PDIP (PDG48) variant.
Technical Context
The 7132LA100PDG implements independent left/right ports with separate address (A0–A10), data (I/O0–I/O7), and control lines (CEL/CER, OEL/OER, R/WL/R/WR), enabling true asynchronous concurrent access. Its on-chip arbitration logic resolves port contention via BUSYL/BUSYR outputs-asserted when both ports target the same address-and enforces deterministic priority based on signal arrival timing (tAPS = 5 ns min).
This device uses CMOS technology to achieve 325 mW typical active power and 1 µA typical full-standby current (ISB3) under CMOS-level inputs. The LA version supports battery backup operation at VCC = 2 V with guaranteed data retention, while its open-drain BUSY outputs require external 270 Ω pull-up resistors per datasheet specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8 (2048 words × 8 bits); supports independent dual-port read/write without external logic |
| Max Read/Write Cycle Time | 100 ns - defines minimum time between successive accesses on same port; critical for real-time interrupt handlers |
| Full Standby Current (ISB3) | 1 µA typical - achieved when both CE pins > VCC − 0.2 V and all inputs at rail; enables ultra-low-power battery backup mode |
| VCC for Data Retention | 2.0 V - guarantees nonvolatile data hold during main power loss; validated per Table 6 in datasheet |
| BUSY Output Type | Open-drain (BUSYL/BUSYR) - requires external 270 Ω pull-up; enables wired-OR arbitration in multi-SRAM width-expansion topologies |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments; not rated for commercial (0°C–70°C) or military (–55°C–125°C) grades |
| Supply Voltage | 4.5 V to 5.5 V - TTL-compatible single 5 V ±10% rail; no dual-supply or level-shifting required |
Pinout & Package
7132LA100PDG is packaged in a 48-pin plastic DIP (PDG48), with body dimensions approximately 0.55 in × 2.43 in × 0.18 in. All VCC and GND pins must be connected per datasheet Note 1 and 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24) | Ground reference | Two dedicated ground pins ensure stable return path for both ports; decoupling required near each |
| VCC (Pin 25) | Power supply | Single 5 V supply powers entire device; multiple VCC pins exist in other packages but only one in PDG48 |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; drives ISB1/ISB2/ISB3 current states depending on logic level and input type |
| OEL / OER | Output enable (left/right) | Active-low controls I/O drivers; high-Z state enabled when OE = VIH, reducing bus contention risk |
| R/WL / R/WR | Read/write control (left/right) | Active-low write command; determines direction of data flow on I/O pins during CE-active cycles |
| BUSYL / BUSYR | Busy flag (left/right) | Open-drain outputs indicating port contention; require 270 Ω pull-up; used for hardware stall signaling |
| A0L–A10L / A0R–A10R | Address inputs (left/right) | 11-bit addressing per port; A10L/A10R support full 2K depth; match detection triggers BUSY assertion |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (left/right) | Bidirectional 8-bit data buses; high-impedance when CE or OE inactive; compatible with TTL logic levels |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves simultaneous same-address access deterministically using tAPS (5 ns setup), eliminating need for external priority encoder |
| Battery backup data retention | Retains valid data at 2.0 V VCC - enables seamless switchover to backup power in industrial PLCs and medical monitors |
| Master/Slave expandability | One 7132LA100PDG (MASTER) + multiple 7142LA100xx (SLAVE) enables error-free 16-bit+ word width without glue logic or timing penalties |
| Ultra-low full-standby current | 1 µA typical (ISB3) - reduces system quiescent power by >99% vs active mode; critical for always-on edge nodes |
| Open-drain BUSY outputs | Supports wired-OR arbitration across multiple MASTER devices; eliminates external AND gates in depth-expanded arrays |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress CY7C1371D-100AXC | 100 ns access, 2K × 16 organization, 3.3 V core (5 V tolerant I/O), no built-in BUSY arbitration | Requires external logic for port contention resolution; lacks battery backup mode | Select when migrating to lower-voltage systems and external arbitration is acceptable |
| ISSI IS61LV25616AL-100TQLI | 100 ns, 256K × 16, 3.3 V only, asynchronous dual-port, no BUSY or master/slave capability | Higher density but no hardware arbitration; incompatible voltage and feature set | Choose only for greenfield designs requiring larger memory without legacy BUSY protocol constraints |
Compared with CY7C1371D-100AXC and IS61LV25616AL-100TQLI, the 7132LA100PDG uniquely delivers integrated arbitration, 5 V compatibility, and 2 V battery retention-making it irreplaceable in industrial motion and avionics where deterministic contention handling and power-fail resilience are mandatory.

FAQ
What is the maximum operating temperature range for the 7132LA100PDG?
The 7132LA100PDG is qualified for the industrial temperature range of –40°C to +85°C. It is not rated for commercial (0°C to +70°C) or military (–55°C to +125°C) grades. This rating is explicitly confirmed in the "Recommended Operating Temperature and Supply Voltage" table (Table 2) and applies to all speed grades of the LA variant in PDG48 packaging.
Does the 7132LA100PDG support battery backup operation, and what voltage is required?
Yes, the 7132LA100PDG supports battery backup data retention at VCC = 2.0 V, as specified in the "Data Retention Characteristics (LA Version Only)" section. This mode guarantees data integrity during main power loss and is validated per Table 6 (VDR = 2.0 V min, ICCDR ≤ 4000 µA for industrial grade). The SA variant does not support this feature.
How does the BUSY arbitration logic function in the 7132LA100PDG?
The 7132LA100PDG implements on-chip arbitration that asserts BUSYL or BUSYR (open-drain) when both ports access the same address. Priority is determined by which port's address and chip-enable signals stabilize first, with a 5 ns arbitration priority setup time (tAPS). This hardware mechanism eliminates software locks and ensures deterministic resolution without external logic.
What is the full standby current (ISB3) specification for the 7132LA100PDG?
The full standby current (ISB3) for the 7132LA100PDG is 1.0 µA typical and 4 µA maximum under industrial conditions, measured when both CEL and CER are held > VCC − 0.2 V and all inputs are at rail (VCC − 0.2 V or < 0.2 V). This ultra-low value enables extended battery backup operation and is a key differentiator versus SA variants (15 µA max).
Is the 7132LA100PDG pin-compatible with other members of the IDT7132/7142 family?
The 7132LA100PDG shares identical pinout with all 48-pin DIP variants of the IDT7132/7142 family (e.g., 7132SA100PDG, 7142LA100PDG), including PDG48 and SB48 packages. Pin functions-including BUSYL/BUSYR as outputs (MASTER) or inputs (SLAVE)-are consistent across speed grades and power variants within the same package type.
