Product details

Overview

70V06L45PF8 from IDT (now Renesas) is a high-speed 3.3V 16K × 8 dual-port static RAM with true independent left/right ports, 45 ns maximum read cycle time, industrial temperature range (−40°C to +85°C), and full on-chip semaphore and interrupt logic for inter-processor communication in real-time embedded systems.

For engineers reviewing the 70V06L45PF8 datasheet, 70V06L45PF8 pinout, 70V06L45PF8 application, or 70V06L45PF8 equivalent, key selection criteria include port arbitration timing (tAPS = 5 ns), BUSY flag response (tBAA ≤ 20 ns), low standby current (ISB3 = 0.2 mA typ.), and compatibility with 3.3V TTL-level control signals.

Technical Context

The 70V06L45PF8 implements fully asynchronous dual-port operation with separate address, data, and control buses per port-enabling simultaneous reads of identical memory locations without contention. Its internal arbitration logic resolves port conflicts via hardware BUSY flags and master/slave configuration using the M/S pin.

It supports three distinct functional modes: standard SRAM access (CE = VIL, SEM = VIH), semaphore register access (CE = VIH, SEM = VIL), and interrupt mailbox handling (INTL/INTR triggered by writes to fixed addresses 3FFE_H/3FFF_H). All modes operate at 3.3V ±0.3V with CMOS-compatible input thresholds.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Organization	16K × 8 bits (128 Kbit total), two independent 16-bit address spaces (A0–A13)
Access Time (tRC)	45 ns max - defines minimum read cycle interval for sustained throughput
Supply Voltage	3.3 V ±0.3 V - single-rail operation compatible with modern 3.3V logic families
Operating Temperature	−40°C to +85°C - qualified for industrial-grade embedded control and communications equipment
Standby Current (ISB3)	0.2 mA typical - ultra-low power retention mode with CMOS-level inputs disabled
Port Arbitration Setup (tAPS)	5 ns min - ensures deterministic priority resolution during simultaneous address matches
BUSY Access Time (tBAA)	20 ns max - latency from address match to BUSY assertion for conflict detection

Pinout & Package

70V06L45PF8 is packaged in a 64-pin TQFP (PNG64) measuring 14 mm × 14 mm × 1.4 mm, with 48 I/O and control terminals distributed across two symmetrical port groups plus shared power/ground pins.

Pin/Terminal	Circuit Role	Design Meaning
CEL / CER	Chip Enable (Left / Right)	Active-low enable per port; controls power-down entry and memory access permission
R/WL / R/WR	Read/Write Control (Left / Right)	Determines direction of data transfer on respective I/O bus; must be HIGH during address transitions
OEL / OER	Output Enable (Left / Right)	Tri-states I/O pins independently; allows one port to drive while other reads or idles
A0L–A13L / A0R–A13R	Address Inputs (Left / Right)	14-bit address space per port (0–16,383); supports full 16K × 8 addressing
I/O0L–I/O7L / I/O0R–I/O7R	Data I/O (Left / Right)	Bidirectional 8-bit data path per port; electrically isolated with independent drivers/receivers
SEML / SEMR	Semaphore Enable (Left / Right)	Activates 3-bit addressable semaphore register bank (8 flags) when CE is HIGH
INTL / INTR	Interrupt Flag Output (Left / Right)	Open-drain compatible push-pull outputs signaling mailbox events (3FFE_H/3FFF_H)
BUSYL / BUSYR	Busy Flag (Left / Right)	Push-pull output (Master) or input (Slave); asserts when both ports access same address simultaneously
M/S	Master/Slave Select	VIL configures device as Slave (BUSY input); VIH configures as Master (BUSY output)
VDD / VSS	Power / Ground	Four VDD and six VSS pins ensure stable 3.3V supply distribution and noise immunity

Key Features

Feature	Design Value
True Dual-Port Architecture	Enables concurrent read operations from both ports to identical memory locations without arbitration delay
Hardware Semaphore Logic	Eight dedicated flags accessible via A0–A2, enabling lock-step synchronization between processors without software overhead
Configurable Master/Slave Mode	M/S pin selects BUSY behavior: output (Master) for conflict detection or input (Slave) for write inhibition during contention
Integrated Interrupt Mailbox	Fixed-address mailboxes (3FFE_H/3FFF_H) provide zero-latency inter-processor signaling with automatic flag set/clear
Low-Power Standby Modes	ISB3 = 0.2 mA typ. with CMOS-level inputs; enables battery-backed operation down to 2V data retention

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C024AV-45AXC	45 ns access, 16K × 16 organization, 3.3V supply, but no integrated semaphore logic	Requires external logic for inter-processor synchronization; wider data bus reduces port count needed for same bandwidth	Select when 16-bit data path is required and semaphore functionality is implemented in firmware or companion logic
IDT70V25L25PF	25 ns access, 32K × 8 organization, same pinout family but faster speed grade and larger memory	Higher performance and capacity, but increased power consumption (IDD = 130 mA typ. vs. 125 mA)	Choose when system demands lower latency or expanded buffer size and thermal/power budget permits

FAQ

What is the maximum operating temperature range for the 70V06L45PF8?

The 70V06L45PF8 is rated for industrial temperature operation from −40°C to +85°C, making it suitable for deployment in harsh environments such as factory automation controllers, outdoor telecom infrastructure, and transportation electronics where ambient thermal stability cannot be guaranteed.

Does the 70V06L45PF8 support battery backup operation?

Yes, the 70V06L45PF8 supports battery backup operation with 2V data retention capability. When main VDD drops below 2V, the device maintains stored data integrity without corruption, enabling seamless failover in systems with auxiliary power sources like supercapacitors or coin cells.

How does the M/S pin affect BUSY signal behavior on the 70V06L45PF8?

When M/S = VIH, the 70V06L45PF8 operates as a Master: BUSYL and BUSYR are push-pull outputs that assert LOW during port 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 arbitration.

What are the valid addresses for interrupt mailbox functionality in the 70V06L45PF8?

The 70V06L45PF8 uses fixed addresses 3FFE_H (16,382 decimal) to set the left port interrupt flag (INTL) and 3FFF_H (16,383 decimal) to set the right port interrupt flag (INTR). Reading these same addresses clears their respective flags, enabling simple mailbox-style inter-processor signaling.

Can the 70V06L45PF8 be used in a 16-bit data bus configuration?

Yes, the 70V06L45PF8 supports 16-bit expansion via Master/Slave cascading. Two devices can be configured-one as Master (M/S = VIH), one as Slave (M/S = VIL)-with BUSY chaining to maintain full-speed error-free operation without external logic, effectively doubling data width to 16 bits.
