Product details
Overview
70V06L15JG8 from IDT (Integrated Device Technology) is a high-speed, 3.3V, 16K × 8 true dual-port static RAM with independent left/right ports, 15 ns max access time (commercial grade), TTL-compatible I/O, and on-chip semaphore/interrupt/arbitration logic - used in real-time inter-processor communication systems requiring simultaneous memory access without contention.
For engineers reviewing the 70V06L15JG8 datasheet, 70V06L15JG8 pinout, 70V06L15JG8 application, or 70V06L15JG8 equivalent, key selection criteria include port arbitration timing (tAPS = 5 ns), BUSY flag behavior under address match (tBAA ≤ 15 ns), dual-port power-down current (ISB3 = 0.2 µA typ.), and PLCC-68 package compatibility with legacy board layouts.
Technical Context
The 70V06L15JG8 implements fully asynchronous dual-port operation with separate address, control, and data buses per port. Its hardware arbitration uses push-pull BUSY outputs (not open-drain) and supports both address-match and chip-enable arbitration modes, with tAPS = 5 ns setup time ensuring deterministic priority resolution.
It integrates dedicated semaphore registers (8 flags, addressed via A0–A2), interrupt mailbox logic (INTL/INTR at 3FFEh/3FFFh), and master/slave configuration via M/S pin - enabling lock-free synchronization between heterogeneous processors without external logic.

FAQ
What is the maximum operating frequency supported by the 70V06L15JG8?
The 70V06L15JG8 supports a maximum read cycle time (tRC) of 15 ns, corresponding to a theoretical maximum operating frequency of 66.7 MHz for non-overlapped cycles. Actual system clock rate depends on address/control setup/hold times and bus loading, but the device is rated for sustained 15 ns access under commercial temperature and 3.3 V supply conditions as specified in the official IDT datasheet revision Feb.07.20.
Does the 70V06L15JG8 support battery backup operation?
Yes, the 70V06L15JG8 supports battery backup operation with data retention down to 2 V, allowing it to maintain memory contents during main power loss. This feature is explicitly documented in the "Features" section and DC characteristics table of the IDT datasheet, making the 70V06L15JG8 suitable for UPS-backed industrial controllers and avionics systems requiring non-volatile state preservation.
How does the BUSY arbitration logic function in the 70V06L15JG8?
The 70V06L15JG8 implements hardware BUSY arbitration that asserts BUSYL or BUSYR when both ports attempt simultaneous access to the same memory address. With M/S = VIH (Master), BUSY outputs are push-pull and inhibit writes if asserted; tAPS = 5 ns ensures priority resolution. The 70V06L15JG8 datasheet confirms this behavior in Truth Table IV and timing waveforms (drw 12–15), with tBAA ≤ 15 ns access time guaranteeing deterministic response.
Can the 70V06L15JG8 be used in industrial temperature applications?
No - the 70V06L15JG8 is rated only for commercial temperature range (0°C to +70°C), as indicated by the "L" suffix and confirmed in the "70V06X15 Com'l Only" designation in Tables 11a and 12a of the IDT datasheet. For industrial (-40°C to +85°C) operation, the 70V06L20JG8 (20 ns version) or 70V06L25JG8 would be required; the 70V06L15JG8 is not characterized or guaranteed for extended temperature use.
What package type is used for the 70V06L15JG8?
The 70V06L15JG8 uses a 68-pin Plastic Leaded Chip Carrier (PLCC) package, designated by the "JG8" suffix. This is confirmed in the Pin Configuration diagrams (drw 02, drw 04), mechanical notes ("PLG68 package body is approximately .95 in x .95 in"), and ordering information tables in the IDT datasheet. It is not available in TQFP or PGA variants under this specific part number.
