Product details
Overview
70V06L20PFGI8 from IDT (now Renesas) is an industrial-grade, 3.3V, 16K × 8 true dual-port static RAM with independent left/right ports, 20 ns max access time, on-chip semaphore and interrupt logic, and Master/Slave arbitration-used in real-time inter-processor communication systems such as radar signal processors and industrial PLCs.
For engineers reviewing the 70V06L20PFGI8 datasheet, 70V06L20PFGI8 pinout, 70V06L20PFGI8 application, or 70V06L20PFGI8 equivalent, key selection criteria include port-to-port contention timing (tBDD ≤ 30 ns), BUSY arbitration setup (tAPS = 5 ns), 2V data retention capability, and compatibility with 64-pin TQFP layout for space-constrained embedded control modules.
Technical Context
The 70V06L20PFGI8 implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port. Its hardware arbitration uses push-pull BUSY outputs (not open-drain) and supports both address-match and CE-driven arbitration modes with tAPS = 5 ns priority setup.
It integrates dedicated semaphore registers (8 flags, addressed via A0–A2) and interrupt mailbox logic (INTL/INTR triggered at addresses 3FFEH/3FFFH), enabling lock-free inter-processor synchronization without external logic. The device operates across –40°C to +85°C with 3.3 V ±0.3 V supply and supports battery backup down to 2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (128 Kbit), two independent addressable spaces |
| Access Time (max) | 20 ns - guarantees deterministic read latency for hard real-time control loops |
| Supply Voltage | 3.3 V ±0.3 V - compatible with modern low-voltage digital logic families |
| Data Retention | 2 V minimum - enables seamless switchover to backup power during main supply loss |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation and transportation electronics |
| Standby Current (ISB3) | 0.2 µA typ. - ultra-low power state when both ports disabled with CMOS-level inputs |
| Port Arbitration | Hardware BUSY flag with tBDD ≤ 30 ns - ensures safe concurrent access without software overhead |
Pinout & Package
70V06L20PFGI8 is packaged in a 64-pin thin quad flatpack (TQFP), body size 14 mm × 14 mm × 1.4 mm, lead pitch 0.5 mm, RoHS-compliant and green-compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left port address inputs | 14-bit address bus for left-side memory access (16K locations) |
| A0R–A13R | Right port address inputs | Independent 14-bit address bus for right-side access |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit parallel data path; high-impedance when OEL = VIH or CEL = VIH |
| I/O0R–I/O7R | Right port bidirectional data | Electrically isolated from left port; no shared data lines |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; controls automatic power-down mode |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; high = read or high-Z output state |
| OEL / OER | Output enable (left/right) | Active-low enables data drivers; overrides R/W state for output control |
| SEML / SEMR | Semaphore enable (left/right) | Active-low selects semaphore register access instead of memory array |
| INTL / INTR | Interrupt flag outputs | Open-collector compatible (per truth table); asserted by opposite port mailbox writes |
| BUSYL / BUSYR | Busy flag (input/output) | Push-pull; output when M/S = VIH (Master), input when M/S = VIL (Slave) |
| M/S | Master/Slave select | VIH configures BUSYL/BUSYR as outputs; VIL configures them as arbitration inputs |
| VDD / VSS | Power / ground | Four VDD and six VSS pins distributed for low-noise, low-impedance supply routing |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port architecture | Simultaneous independent read/write to same location without corruption-enables zero-latency inter-core data exchange |
| On-chip semaphore logic | Eight hardware semaphore flags (A0–A2 addressable) eliminate need for external locking circuitry or polling loops |
| Hardware interrupt mailbox | Dedicated 3FFEH/3FFFH addresses trigger INTL/INTR flags-reduces inter-processor signaling latency to ≤20 ns |
| Master/Slave cascading support | M/S pin enables multi-device 16-bit+ data bus expansion without external glue logic or timing compensation |
| Industrial temperature grade | –40°C to +85°C operation with guaranteed 20 ns access time-validated for harsh factory-floor environments |

FAQ
What is the maximum operating temperature range for the 70V06L20PFGI8?
The 70V06L20PFGI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is guaranteed across all electrical parameters including 20 ns access time, BUSY arbitration timing (tAPS = 5 ns), and standby current (ISB3 ≤ 0.2 µA). It is not qualified for extended commercial (0°C to +70°C) or military ranges.
Does the 70V06L20PFGI8 support battery backup operation?
Yes, the 70V06L20PFGI8 supports battery backup with guaranteed data retention down to 2 V. When VDD drops below 2.0 V, the device enters data-hold mode-maintaining memory contents without refresh. This feature enables seamless transition to backup power in industrial controllers and avionics systems where uninterrupted state preservation is critical.
How does the Master/Slave (M/S) pin affect BUSY signal behavior on the 70V06L20PFGI8?
When M/S = VIH, the 70V06L20PFGI8 operates as Master: BUSYL and BUSYR are push-pull outputs indicating port contention. When M/S = VIL, it operates as Slave: BUSYL and BUSYR become inputs that inhibit writes when driven low by a Master device. This configuration enables hierarchical arbitration in multi-device systems without external logic.
Can the 70V06L20PFGI8 be used for semaphore-based resource locking between two microcontrollers?
Yes, the 70V06L20PFGI8 includes eight dedicated hardware semaphore flags accessible via A0–A2 and controlled by SEML/SEMR. Each flag can be written by one port and read by both, enabling atomic acquire/release operations. No external logic or software polling is required-semaphore state changes propagate within ≤10 ns (tSOP).
What package type is used for the 70V06L20PFGI8?
70V06L20PFGI8 uses a 64-pin thin quad flatpack (TQFP) package, designated PNG64, with dimensions 14 mm × 14 mm × 1.4 mm and 0.5 mm lead pitch. This RoHS-compliant, green-compatible package supports automated SMT assembly and provides thermal and electrical performance suitable for industrial PCBs.
