Product details
Overview
70V06S20PF from IDT (Integrated Device Technology) is a high-speed 3.3V 16K × 8 dual-port static RAM with true independent left/right ports, 20 ns maximum access time (industrial grade), TTL-compatible I/O, and full on-chip semaphore and interrupt logic for inter-processor communication in real-time embedded systems.
For engineers reviewing the 70V06S20PF datasheet, 70V06S20PF pinout, 70V06S20PF application, or 70V06S20PF equivalent, this page delivers verified timing specs, master/slave arbitration behavior, BUSY/INT/SEM signal semantics, and package-specific pin mapping for reliable co-processor memory design.
Technical Context
The 70V06S20PF implements fully asynchronous dual-port architecture with separate address, control, and data buses per port-enabling simultaneous read/write to any memory location without contention-induced corruption. Its hardware arbitration uses push-pull BUSY outputs and M/S-selectable master/slave mode to resolve port conflicts deterministically.
It integrates dedicated semaphore registers (8 flags, addressed via A0–A2), interrupt mailbox logic (INTL/INTR at 3FFE/3FFF), and automatic power-down per port via CE-driven standby modes-supporting battery-backed operation down to 2V with data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (128 Kbit total); supports 16-bit+ bus expansion via M/S cascading |
| Access Time (tAA) | 20 ns max (industrial temp range −40°C to +85°C); guarantees deterministic latency under worst-case conditions |
| Supply Voltage | 3.3 V ± 0.3 V; single-supply TTL-compatible operation eliminates level-shifting requirements |
| Standby Current (ISB3) | 0.2 µA typical (full CMOS standby); enables ultra-low-power hold mode during processor sleep |
| Bus Interface | True dual-port: independent A0–A13, I/O0–I/O7, CEL/CER, R/WL/R/WR, OEL/OER per side |
| Arbitration Logic | On-chip hardware BUSY flag generation with tAPS = 5 ns setup; no external glue logic needed |
| Semaphore Support | 8 dedicated flags accessible via SEM = VIL; write to I/O0, read across I/O0–I/O7 using A0–A2 |
Pinout & Package
70V06S20PF is packaged in a 68-pin PLCC (PLG68) with 0.05-inch lead pitch, body size ≈ 0.95 in × 0.95 in × 0.17 in. All VDD pins require local decoupling; all VSS pins must be solidly grounded.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left port address inputs | 14-bit address bus for left-side memory access; latched on CE/R/W edge |
| A0R–A13R | Right port address inputs | 14-bit address bus for right-side memory access; fully independent of left port |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit parallel data path; tri-stated when OEL = VIH or CEL = VIH |
| I/O0R–I/O7R | Right port bidirectional data | 8-bit parallel data path; isolated from left port I/Os electrically and timing-wise |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; drives internal power-down when high |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; high = read (outputs enabled if OE active) |
| OEL / OER | Output enable (left/right) | Active-low enables I/O drivers; overrides R/W state for output gating |
| SEML / SEMR | Semaphore enable (left/right) | Active-low selects semaphore register space instead of memory array |
| INTL / INTR | Interrupt flag outputs | Open-drain compatible push-pull outputs; set/cleared by cross-port writes to 3FFE/3FFF |
| BUSYL / BUSYR | Busy flag (input/output) | Push-pull; output when M/S = VIH (master), input when M/S = VIL (slave); asserts on address match |
| M/S | Master/Slave select | VIL configures as slave (BUSY input); VIH configures as master (BUSY output); determines arbitration priority |
| VDD | Power supply | 3.3 V ± 0.3 V; 7 dedicated pins for low-noise distribution |
| VSS | Ground | 0 V reference; 8 dedicated pins for low-impedance return path |
Key Features
| Feature | Design Value |

FAQ
What is the operating temperature range for the 70V06S20PF?
The 70V06S20PF 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, standby current, and BUSY arbitration timing-making it suitable for harsh-environment applications like factory automation and transportation systems.
Does the 70V06S20PF support battery backup operation?
Yes, the 70V06S20PF supports battery backup operation with data retention down to 2 V supply voltage. This feature ensures memory contents remain intact during main power loss, enabling safe state preservation in UPS-dependent or mission-critical systems without external non-volatile storage.
How does the M/S pin affect BUSY signal behavior on the 70V06S20PF?
When M/S = VIH, the 70V06S20PF operates as a master: BUSYL and BUSYR are push-pull outputs that assert when address contention occurs. When M/S = VIL, it operates as a slave: BUSYL and BUSYR become inputs that inhibit writes when driven low by a master-enabling hierarchical arbitration in multi-device configurations.
Can the 70V06S20PF be used in a 16-bit data bus configuration?
Yes, the 70V06S20PF supports 16-bit expansion via master/slave cascading. Two devices can be connected with M/S pins configured oppositely, using the BUSY outputs of the master to control write enable on the slave-achieving full-speed 16-bit access without external logic or performance penalty.
What are the valid interrupt address locations for the 70V06S20PF?
The 70V06S20PF uses fixed interrupt mailbox addresses: writing to 3FFE (hex) sets the left port INTL flag, and writing to 3FFF (hex) sets the right port INTR flag. Reading those same addresses clears the respective flags-providing atomic, zero-software-overhead inter-processor signaling.
