Renesas 70V05L15PF8

Overview

IDT70V05L15PF8 from Integrated Device Technology (IDT) is a high-speed 3.3V 8K × 8 dual-port static RAM with true independent left/right ports, 15 ns maximum access time (commercial grade), 380 mW typical active power, and integrated semaphore/arbiter logic for inter-port synchronization. It enables simultaneous read/write access to the same memory location in real-time control systems requiring deterministic data exchange between two processors or bus domains.

For engineers reviewing the IDT70V05L15PF8 datasheet, IDT70V05L15PF8 pinout, IDT70V05L15PF8 application, or IDT70V05L15PF8 equivalent, key selection criteria include dual-port arbitration timing (tAPS, tBDD), BUSY flag behavior under M/S = VIH/VIH configuration, industrial temperature support (-40°C to +85°C), and compatibility with 3.3V ±0.3V single-supply operation without level-shifting.

Technical Context

The IDT70V05L15PF8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port. Its on-chip arbitration logic resolves contention via hardware BUSY signaling and supports both address-match and CE-driven arbitration modes with programmable master/slave configuration via the M/S pin.

It integrates full semaphore functionality-eight flags accessible via A0–A2-with dedicated SEM pins and interrupt generation (INTL/INTR) triggered by write-to-interrupt-address events. All timing parameters-including tRC (20 ns min), tAA (15 ns max), and tBDD (≤20 ns)-are specified over VDD = 3.3V ±0.3V and commercial temperature range.

IDT70V05L15PF8 belongs to the IDT70V05 family of high-speed dual-port SRAMs designed specifically for deterministic inter-processor communication in industrial automation, telecommunications infrastructure, and real-time embedded systems.

FAQ

What is the maximum operating temperature range for the IDT70V05L15PF8?

The IDT70V05L15PF8 is rated for industrial temperature operation from -40°C to +85°C. This specification is confirmed in the "Features" section and DC Electrical Characteristics table, where TA = +85°C is explicitly listed as the maximum operating temperature under VDD = 3.3V ±0.3V conditions. The device maintains full 15 ns access time performance across this range.

Does the IDT70V05L15PF8 support true simultaneous read operations on both ports to the same memory address?

Yes, the IDT70V05L15PF8 supports true simultaneous reads to the same memory location on both ports. This capability is explicitly stated in the "Features" section: "True Dual-Ported memory cells which allow simultaneous reads of the same memory location." No arbitration or BUSY assertion occurs during concurrent reads, ensuring deterministic latency.

How does the M/S pin affect BUSY signal behavior on the IDT70V05L15PF8?

When M/S = VIH, the IDT70V05L15PF8 operates as a master: BUSYL and BUSYR become push-pull outputs reflecting local port contention status. 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 documented in the Functional Block Diagram notes and Pin Configurations section.

What is the standby current consumption of the IDT70V05L15PF8?

The IDT70V05L15PF8 consumes 660 μW typical standby power, equivalent to approximately 200 μA at 3.3 V. This value is specified in the "Features" section and verified in the DC Electrical Characteristics table under "I_SB - Standby Current" for L-grade devices at VDD = 3.3 V and TA = +25°C.

Can the IDT70V05L15PF8 be used in a 16-bit data bus configuration?

Yes, the IDT70V05L15PF8 supports 16-bit expansion via master/slave cascading. As stated in the "Features" section: "IDT70V05 easily expands data bus width to 16 bits or more using the Master/Slave select when cascading more than one device." Two IDT70V05L15PF8 units-one configured as master, one as slave-provide full 16-bit width with synchronized arbitration.
