Product details
Overview
70V06L20JGI from IDT (now Renesas) is a high-speed 3.3V 16K × 8 dual-port static RAM with true independent left/right ports, 20 ns max access time (industrial grade), TTL-compatible I/O, and on-chip semaphore/interrupt arbitration logic - used in real-time inter-processor communication systems requiring concurrent memory access without external logic.
For engineers reviewing the 70V06L20JGI datasheet, 70V06L20JGI pinout, 70V06L20JGI application, or 70V06L20JGI equivalent, key selection criteria include industrial temperature support (−40°C to +85°C), 68-pin PLCC package compatibility, BUSY/INT/SEM hardware arbitration timing, and 2V data retention during battery backup operation.
Technical Context
The 70V06L20JGI implements fully asynchronous dual-port architecture with separate address, control, and bidirectional I/O buses per port (A0L–A13L/I/O0L–I/O7L and A0R–A13R/I/O0R–I/O7R), enabling simultaneous read/write operations to any memory location. Its on-chip arbitration logic resolves contention via BUSY flag assertion (tBAA ≤ 20 ns) and supports master/slave configuration via M/S pin.
It integrates dedicated semaphore registers (8 flags, addressed by A0–A2) accessible when SEM = VIL and CE = VIH, with tSOP = 10 ns semaphore update pulse width and tSPS = 5 ns contention window. Interrupt flags (INTL/INTR) are set/cleared by writes/reads to fixed addresses 3FFEh/3FFFh, with tINS/tINR ≤ 20 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (128 Kbit total), two independent 16K × 8 arrays |
| Access Time (max) | 20 ns - guarantees deterministic read latency for real-time inter-processor handshaking |
| Supply Voltage | 3.3 V ± 0.3 V - compatible with modern low-voltage digital systems; no level-shifting required |
| Operating Temperature | −40°C to +85°C - qualified for industrial embedded control and avionics interfaces |
| Standby Current (ISB3) | 0.2 µA typical - enables ultra-low-power battery-backed retention mode |
| Data Retention Voltage | 2.0 V minimum - maintains memory state during brown-out or backup power conditions |
| Package | 68-pin PLCC (PLG68) - through-hole mountable, RoHS-compliant, thermal profile suitable for reflow/reflow-soldering |
Pinout & Package
68-pin Plastic Leaded Chip Carrier (PLCC), body size ≈ 24.1 mm × 24.1 mm × 4.3 mm, lead pitch 1.27 mm, JEDEC MO-047 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2, 20, 21, 35, 47, 51, 66, 67, 68) | Power Supply | 3.3 V core and I/O supply; all 10 pins must be decoupled locally to ensure stable operation under dual-port switching |
| VSS (Pins 3, 19, 22, 34, 36, 45, 46, 50, 53, 55, 57, 59, 61, 63, 65) | Ground | Common reference for both ports; 15 ground pins minimize ground bounce during simultaneous I/O transitions |
| CEL / CER | Chip Enable (Left/Right) | Active-low enable per port; deassertion places respective port in standby (ISB1 ≤ 30 mA) |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low write enable; controls direction of I/O bus and internal write timing (tWP ≥ 15 ns) |
| OEL / OER | Output Enable (Left/Right) | Active-low output driver control; allows high-impedance tri-state during shared bus operation |
| A0L–A13L / A0R–A13R | Address Inputs (Left/Right) | 14-bit address per port (16K depth); address match triggers BUSY arbitration (tAPS = 5 ns setup) |
| I/O0L–I/O7L / I/O0R–I/O7R | Bidirectional Data Bus (Left/Right) | 8-bit parallel data path per port; supports simultaneous read/write to same or different locations |
| SEML / SEMR | Semaphore Enable (Left/Right) | Active-low enable for semaphore register access; required with CE = VIH to enter semaphore mode |
| INTL / INTR | Interrupt Flag Output (Left/Right) | Open-drain compatible push-pull outputs; set by opposite port writing to 3FFEh/3FFFh |
| BUSYL / BUSYR | Busy Flag (Left/Right) | Push-pull output (Master) or input (Slave); asserts when both ports access same address concurrently |
| M/S | Master/Slave Select | VIH configures device as Master (BUSY outputs); VIL configures as Slave (BUSY inputs, write-inhibited if asserted) |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables simultaneous, independent read/write access from two processors without external arbitration logic or wait states |
| Hardware Semaphore Support | Eight dedicated flags (A0–A2 addressable) with 5 ns contention window (tSPS), eliminating software spinlocks in RTOS environments |
| Integrated Interrupt Logic | Dedicated mailbox addresses (3FFEh/3FFFh) provide zero-latency inter-processor signaling with ≤20 ns flag assertion/reset |
| Master/Slave Cascading | M/S pin enables seamless expansion to 16-bit+ data buses using multiple devices without additional glue logic |
| Battery Backup Retention | Maintains valid data at 2.0 V supply - supports fail-safe state preservation during main power loss |
Applications
| Industrial PLC Communication Bridge | Avionics Sensor Fusion Module |

FAQ
What is the maximum operating temperature range supported by the 70V06L20JGI?
The 70V06L20JGI is rated for industrial temperature operation from −40°C to +85°C, verified across all AC and DC specifications including 20 ns access time, BUSY arbitration timing, and standby current. This makes it suitable for deployment in harsh environments such as factory automation controllers and vehicle-mounted electronics without derating.
Does the 70V06L20JGI support battery backup operation, and what is the minimum retention voltage?
Yes, the 70V06L20JGI supports battery backup operation with guaranteed data retention down to 2.0 V supply voltage. At this level, the device maintains valid memory contents with ISB3 ≤ 0.2 µA typical, enabling fail-safe state preservation during main power interruption - critical for medical and aerospace applications.
How does the M/S pin affect BUSY signal behavior on the 70V06L20JGI?
When M/S = VIH, the 70V06L20JGI operates as a Master: BUSYL and BUSYR are push-pull outputs that assert LOW during address contention. When M/S = VIL, it operates as a Slave: BUSYL and BUSYR become inputs that inhibit writes when driven LOW by a Master device - enabling hierarchical multi-device memory expansion.
What are the address locations used for interrupt flag control in the 70V06L20JGI?
The 70V06L20JGI uses fixed addresses 3FFEh (hex) to set the left port interrupt flag (INTL) and 3FFFh to set the right port flag (INTR). Reading those same addresses clears the respective flags. These locations function as mailboxes only when interrupt mode is enabled; otherwise, they behave as standard RAM locations.
Can the 70V06L20JGI be used in a 16-bit data bus configuration, and how is this achieved?
Yes, the 70V06L20JGI supports 16-bit expansion via Master/Slave cascading. Two devices are connected in parallel with their I/O buses aligned; the M/S pin configures one as Master (BUSY outputs) and the other as Slave (BUSY inputs). This eliminates external logic and preserves full-speed operation across the combined 16-bit width.
