Product details

Overview

70V06L20PF from IDT (Integrated Device Technology) is a high-speed, 3.3V, 16K × 8 true dual-port static RAM with independent left/right ports, 20 ns maximum access time (industrial grade), TTL-compatible I/O, and on-chip semaphore/interrupt arbitration logic. It enables simultaneous asynchronous reads of the same memory location and supports master/slave cascading for 16-bit+ bus expansion in real-time inter-processor communication systems.

For engineers reviewing the 70V06L20PF datasheet, 70V06L20PF pinout, 70V06L20PF application, or 70V06L20PF equivalent, key selection criteria include industrial temperature support (−40°C to +85°C), dual-port contention resolution via BUSY/SEM/INT signals, low standby power (660 µW typ.), and compatibility with 68-pin PLCC packaging for legacy board designs.

Technical Context

The 70V06L20PF implements fully asynchronous dual-port operation with separate address, control, and data buses per port. Its on-chip arbitration logic resolves port-to-port contention using BUSY flag timing (tBAA ≤ 20 ns), semaphore enable (SEML/SEMR), and interrupt set/reset at fixed addresses (3FFE/3FFF hex).

It supports three power states: active (380 mW typ.), TTL-level standby (ISB1 ≤ 30 mA), and CMOS-level full standby (ISB3 ≤ 2.5 mA). Memory array access requires CE = VIL and SEM = VIH; semaphore access requires CE = VIH and SEM = VIL - two distinct operational modes governed by dedicated control pin logic.

Key Specifications

Memory Organization	16K × 8 bits (128 Kbit total), dual-port SRAM with independent left/right address/data/control paths
Access Time	20 ns max (industrial temp range −40°C to +85°C), enabling real-time deterministic response in embedded control loops
Supply Voltage	3.3 V ± 0.3 V - single-rail TTL-compatible operation without level-shifting circuitry
Standby Power	660 µW typical - supports battery-backed retention down to 2 V with data integrity preserved

Pinout & Package

68-pin PLCC package (IDT package code PLG68), body size ≈ 1.18 in × 1.18 in × 0.16 in. All VDD pins require connection to 3.3 V supply; all VSS pins must be grounded.

Pin/Terminal	Circuit Role	Design Meaning
CEL / CER	Chip Enable (Left / Right)	Active-low port selection - disables respective port's internal circuitry and reduces current draw to ISB1/ISB3 levels
R/WL / R/WR	Read/Write Control (Left / Right)	Active-low write enable - determines direction of data flow on I/O0–I/O7 for each port independently
OEL / OER	Output Enable (Left / Right)	Active-low output driver control - places I/O bus in high-impedance state when deasserted
A0L–A13L / A0R–A13R	Address Inputs (Left / Right)	14-bit address bus per port - selects one of 16,384 memory locations (0000h–3FFFh) for read/write operations
I/O0L–I/O7L / I/O0R–I/O7R	Data I/O (Left / Right)	Bidirectional 8-bit data path - shares pins for input and output; direction controlled by R/W and OE states
SEML / SEMR	Semaphore Enable (Left / Right)	Active-low semaphore mode selector - enables access to eight hardware semaphore flags via A0–A2 addressing
INTL / INTR	Interrupt Flag (Left / Right)	Open-drain push-pull output - asserts low when opposite port writes to mailbox address (3FFEh / 3FFFh)
BUSYL / BUSYR	Busy Flag (Left / Right)	Push-pull output (Master) or input (Slave) - indicates port-to-port address contention; inhibits writes when asserted
M/S	Master/Slave Select	High = Master (BUSY outputs); Low = Slave (BUSY inputs) - enables hardware arbitration in multi-device configurations

Key Features

Feature	Design Value
True dual-port memory cells	Enables simultaneous read access to identical memory locations from both ports - eliminates software polling or lock-step synchronization
On-chip semaphore logic	Eight hardware semaphore flags accessible via A0–A2 - provides atomic resource locking without external logic or CPU intervention
Hardware interrupt mailbox	Dedicated 3FFEh (left) and 3FFFh (right) addresses - enables zero-latency inter-processor signaling with automatic flag assertion/clearing
Automatic power-down control	CE-driven standby mode reduces active port current to ISB2/ISB4 levels - simplifies thermal management in dense PCB layouts
Master/slave cascading support	M/S pin configures BUSY as output (Master) or input (Slave) - allows seamless expansion to 16-bit+ data buses without glue logic

FAQ

What is the operating temperature range supported by the 70V06L20PF?

70V06L20PF is rated for industrial temperature operation from −40°C to +85°C. This specification is confirmed in the DC Electrical Characteristics table (Table 05) and applies to all timing parameters including 20 ns access time, BUSY arbitration, and semaphore functionality - ensuring reliable performance in harsh environments such as factory automation and outdoor infrastructure.

Does the 70V06L20PF support battery backup operation?

Yes, the 70V06L20PF supports battery backup operation with 2 V data retention. As stated in the Features section and confirmed in the DC Electrical Characteristics (Table 04), the device maintains stored data when VDD drops to 2 V - enabling seamless transition to backup power during main supply interruption without data loss.

How does the M/S pin affect BUSY signal behavior on the 70V06L20PF?

When M/S = VIH, the 70V06L20PF 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 - enabling hardware-enforced priority arbitration in multi-device configurations without external logic.

Can the 70V06L20PF perform simultaneous reads from both ports to the same memory address?

Yes, the 70V06L20PF features true dual-ported memory cells that allow simultaneous reads of the same memory location from both left and right ports without contention, delay, or data corruption - a core capability explicitly highlighted in the Features section and validated by the Functional Block Diagram and Truth Table I.

What package type is used for the 70V06L20PF?

70V06L20PF uses a 68-pin Plastic Leaded Chip Carrier (PLCC) package, designated PLG68 in IDT documentation. The physical dimensions are approximately 1.18 in × 1.18 in × 0.16 in, and the pin configuration matches the top-view diagram in Drawing 02 - confirming through-hole mounting compatibility and standard PLCC socket support.
