Renesas 70V3569S6DRI

Overview

70V3569S6DRI 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 70V3569S6DRI datasheet, 70V3569S6DRI pinout, 70V3569S6DRI application, or 70V3569S6DRI equivalent, this page delivers verified timing parameters, industrial-grade (-40°C to +85°C) operation, dual-chip-enable depth expansion support, and confirmed 208-pin PQFP package mapping - all critical for deterministic real-time memory subsystem design.

Technical Context

The 70V3569S6DRI implements full synchronous operation on both ports using edge-triggered registers for address, data, and control inputs, enabling minimal setup (1.8 ns) and hold (0.7 ns) times at 133 MHz. Its pipelined output mode introduces one-cycle latency but guarantees deterministic tCD2 ≤ 6 ns for predictable timing closure.

It supports independent voltage configuration per port via OPTL/OPTR pins: VDDQ can be set to either 3.3 V (±150 mV) or 2.5 V (±125 mV), while core VDD remains fixed at 3.3 V. The dual-chip-enable architecture (CE0X/CE1X) allows seamless depth expansion without external logic.

Key Specifications

Pinout & Package

70V3569S6DRI is packaged in a 208-pin Plastic Quad Flatpack (PQFP) with 0.5 mm lead pitch and 28 mm × 28 mm body size. All VDD pins require 3.3 V ±150 mV; VDDQL/VDDQR must match OPTL/OPTR logic levels (3.3 V if VIH, 2.5 V if VIL).

FAQ

What is the maximum operating frequency of the 70V3569S6DRI?

The 70V3569S6DRI supports a minimum clock cycle time of 7.5 ns, corresponding to a maximum operating frequency of 133 MHz under commercial conditions. This is validated for both ports simultaneously with pipelined output mode enabled and all timing margins met per datasheet Table 11.

Does the 70V3569S6DRI support independent I/O voltage selection per port?

Yes, the 70V3569S6DRI supports independent I/O voltage selection via OPTL and OPTR pins: setting OPTL to VIH configures VDDQL for 3.3 V operation, while VIL sets it to 2.5 V - same for OPTR/VDDQR. Core VDD remains fixed at 3.3 V ±150 mV in all configurations.

What package type is used for the 70V3569S6DRI?

The 70V3569S6DRI is supplied in a 208-pin Plastic Quad Flatpack (PQFP) package with 0.5 mm lead pitch and 28 mm × 28 mm body dimensions. Pinout and mechanical drawings are fully documented in IDT datasheet revision DSC 4831/15, Figure DRG208.

How does the address counter function in the 70V3569S6DRI?

The 70V3569S6DRI integrates a 14-bit address counter controlled by CNTENL/CNTENR and CNTRSTL/CNTRSTR. When CNTEN = VIL on CLK rise, the counter advances internally; CNTRST = VIL resets it to address 0. ADS = VIH disables external address loading, allowing pure counter-driven sequential access.

What is the standby current consumption of the 70V3569S6DRI in full CMOS-level shutdown?

In full standby mode (ISB3) with both ports disabled using CMOS-level inputs - CE0X and CE1X held > VDDQ − 0.2 V and all inputs at rail extremes - the 70V3569S6DRI consumes 6 mA typical and 15 mA maximum at +25°C, as specified in Table 9 of the datasheet.
