Renesas 70V3569S6BF8

Overview

70V3569S6BF8 from Integrated Device Technology is a high-speed 16K × 36-bit synchronous dual-port static RAM with pipelined output, 4.2 ns clock-to-data access (max), 7.5 ns cycle time (133 MHz), and independent 3.3 V or 2.5 V I/O voltage selection per port. It enables simultaneous read/write access to the same memory location in telecom packet buffering and FPGA co-processor interconnect applications.

For engineers reviewing the 70V3569S6BF8 datasheet, 70V3569S6BF8 pinout, 70V3569S6BF8 application, or 70V3569S6BF8 equivalent, this page delivers verified timing parameters, port-specific voltage configuration logic, industrial-grade thermal performance (-40°C to +85°C), and depth-expansion-ready chip enable architecture for real-time embedded system design.

Technical Context

The 70V3569S6BF8 implements fully synchronous dual-port operation with registered address, data, and control inputs on both left and right ports-enabling minimal setup/hold times (1.8 ns setup, 0.7 ns hold @133 MHz) and deterministic pipelined latency. Its self-timed write architecture maintains fast cycle time without external wait-state generation.

Each port supports independent I/O voltage selection (3.3 V or 2.5 V) via dedicated OPTL/OPTR pins and corresponding VDDQL/VDDQR supplies, while core logic remains fixed at 3.3 V. The integrated address counter with ADS/CNTEN/CNTRST controls allows burst-mode sequential access without external sequencing logic.

Key Specifications

Pinout & Package

70V3569S6BF8 is housed in a 208-pin PQFP package (DRG208 footprint) with 0.65 mm lead pitch and 28 mm × 28 mm body size. Power and ground pins are distributed across all four sides for low-noise supply routing; VDD (core) and VDDQL/VDDQR (I/O) are independently routed to support mixed-voltage port operation.

FAQ

What is the maximum operating frequency of the 70V3569S6BF8?

The 70V3569S6BF8 supports a minimum clock cycle time of 7.5 ns, enabling guaranteed operation at 133 MHz across its commercial temperature range. This timing is validated under full load conditions with 3.3 V or 2.5 V I/O supplies and meets all AC electrical specifications in the official datasheet.

Does the 70V3569S6BF8 support independent voltage selection on each port?

Yes, the 70V3569S6BF8 supports independent I/O voltage selection per port via OPTL and OPTR pins. Setting OPTL to VIH configures the left port for 3.3 V operation (VDDQL = 3.3 V), while setting OPTR to VIL configures the right port for 2.5 V operation (VDDQR = 2.5 V)-enabling mixed-voltage system integration without external level shifters.

What is the function of the ADSL and ADSR pins on the 70V3569S6BF8?

ADSL (Address Strobe Left) and ADSR (Address Strobe Right) are asynchronous address latch enable inputs. When asserted low, they cause the respective port to capture the current address bus value on the next rising edge of CLKL or CLKR-enabling external address generation independent of the internal counter and supporting non-sequential access patterns.

How does the address counter work on the 70V3569S6BF8?

The 70V3569S6BF8 integrates a 14-bit address counter per port. When CNTENL/R is held low, the counter advances automatically on each CLKL/R rising edge. CNTRSTL/R provides asynchronous reset to address zero. ADSL/R overrides the counter to load external addresses, allowing hybrid burst/non-burst operation within a single device.

What package type is used for the 70V3569S6BF8?

The 70V3569S6BF8 is packaged in a 208-pin Plastic Quad Flatpack (PQFP) with 28 mm × 28 mm body size and 0.65 mm lead pitch. This package is designated DRG208 in IDT documentation and supports standard surface-mount reflow processes with verified thermal performance across -40°C to +85°C.
