Product details
Overview
70V06S20PF8 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 - used in real-time inter-processor communication systems requiring concurrent memory access without arbitration overhead.
For engineers reviewing the 70V06S20PF8 datasheet, 70V06S20PF8 pinout, 70V06S20PF8 application, or 70V06S20PF8 equivalent, this page delivers verified timing specs, master/slave BUSY arbitration behavior, dual-port power-down modes, and exact PLCC-68 pin mapping per official IDT documentation.
Technical Context
The 70V06S20PF8 implements fully asynchronous dual-port operation: each port has dedicated address (A0L–A13L / A0R–A13R), data (I/O0L–I/O7L / I/O0R–I/O7R), and control lines (CEL/CER, R/WL/R/WR, OEL/OER), enabling simultaneous read/write to any memory location. It supports MASTER/SLAVE cascading via M/S pin for 16-bit+ bus expansion.
On-chip hardware includes port-to-port arbitration logic that asserts BUSYL/BUSYR when address contention occurs, semaphore registers (8 flags, addressed by A0–A2), and interrupt flags (INTL/INTR) triggered by writes to fixed mailbox addresses (3FFEh/3FFFh). All logic operates at 3.3V ±0.3V with industrial temperature range support (−40°C to +85°C).

| Interrupt mailbox addressing | Fixed locations 3FFEh (left port INTR set) and 3FFFh (right port INTL set) provide zero-latency inter-processor signaling |
| Battery backup retention | 2 V minimum VDD supports data retention during brownout - critical for fault-tolerant embedded control systems |
Applications
| Industrial PLC Communication Bridge | Real-Time DSP Co-Processor Interface |
|---|---|

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 CY7C028V-20AXC | 20 ns access, 16K × 16 organization, 100-pin TQFP, 3.3V only; no built-in semaphore logic | Requires external logic for semaphore emulation; better suited for wide-bus systems needing 16-bit native width | Select when 16-bit data path is mandatory and external arbitration is acceptable |
| Renesas R1EX24064ASAS-20 | 20 ns access, 8K × 8 organization, 64-pin TQFP, 3.3V; integrated error correction (ECC), no BUSY/interrupt logic | Limited capacity (64 Kbit); ECC adds reliability but increases latency; lacks dual-port arbitration features | Select for space-constrained designs where data integrity outweighs inter-processor coordination needs |
Compared with CY7C028V-20AXC and R1EX24064ASAS-20, the 70V06S20PF8 uniquely integrates hardware semaphore, BUSY arbitration, and interrupt mailbox logic in a 16K × 8 configuration - reducing BOM count and guaranteeing deterministic timing in tightly coupled multi-CPU systems.

FAQ
What is the operating voltage range for the 70V06S20PF8?
The 70V06S20PF8 operates at a nominal 3.3 V supply with a specified range of 3.0 V to 3.6 V. This tolerance ensures robust operation across industrial power rails and allows compatibility with standard 3.3 V LDO regulators. The device maintains full functionality-including 20 ns access time and TTL-compatible I/O levels-across this entire range, as confirmed in IDT DC Electrical Characteristics Table 6.
Does the 70V06S20PF8 support battery backup mode?
Yes, the 70V06S20PF8 supports data retention down to 2.0 V, enabling battery backup operation during main power loss. This feature is explicitly documented in the "Features" section and verified in DC characteristics tables, where standby current remains below 5 µA at 2 V. It is commonly used in industrial controllers to preserve critical state during brownouts.
How does the M/S pin affect BUSY signal behavior on the 70V06S20PF8?
When M/S = VIH, the 70V06S20PF8 operates as a master: BUSYL and BUSYR are push-pull outputs indicating address contention. When M/S = VIL, it operates as a slave: BUSYL and BUSYR become inputs that inhibit writes when asserted low. This dual-mode behavior is defined in Notes 1 and 2 of the Functional Block Diagram and validated in Truth Table IV.
Can the 70V06S20PF8 be used in a 16-bit data bus configuration?
Yes - the 70V06S20PF8 supports 16-bit expansion using master/slave cascading. Two devices are connected with M/S pins set oppositely; the master's BUSY outputs control the slave's BUSY inputs, enabling full-speed, error-free 16-bit access without external glue logic. This capability is detailed in the "Features" section and functional description under "MASTER/SLAVE Dual-Port Static RAM approach."
What are the fixed memory addresses used for interrupt signaling in the 70V06S20PF8?
The 70V06S20PF8 uses address 3FFEh to set the left port interrupt flag (INTL) and 3FFFh to set the right port interrupt flag (INTR). Reading those same addresses clears the respective flags. This mailbox mechanism is defined in Truth Table III and the Functional Description section, and is hardware-implemented - no firmware intervention is required for flag assertion or clearing.
