Product details

Overview

70V3569S5BFI8 from Integrated Device Technology is a high-speed 16K × 36-bit synchronous dual-port static RAM with pipelined output, true dual-port architecture enabling simultaneous read/write access to the same memory location, 5 ns max clock-to-data access (industrial grade), and support for independent 3.3 V or 2.5 V I/O interfaces per port - used in real-time packet buffering for telecom line cards and FPGA co-processor data exchange.

For engineers reviewing the 70V3569S5BFI8 datasheet, 70V3569S5BFI8 pinout, 70V3569S5BFI8 application, or 70V3569S5BFI8 equivalent, this page delivers verified timing parameters, industrial-grade thermal validation (−40°C to +85°C), PQFP-208 package mapping, byte-selectable 9-bit-wide I/O control, and synchronous counter-enable functionality critical for burst-mode data acquisition systems.

Technical Context

The 70V3569S5BFI8 implements fully synchronous dual-port operation on both left and right ports, with all address, data, and control inputs registered on the rising edge of CLKL/CLKR. It supports pipelined output mode with 1-cycle latency, self-timed write cycles, and independent address strobe (ADSL/ADSR) and counter enable (CNTENL/CNTENR) logic per port.

Each port features separate byte enables (BE0–BE3), asynchronous output enable (OEL/OER), and configurable I/O voltage via OPTL/OPTR pins - allowing mixed-voltage system interfacing (e.g., 3.3 V core with 2.5 V FPGA I/O). The device uses true dual-port SRAM cells, not pseudo-dual-port or FIFO-based emulation.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Organization	16K × 36 bits (576 Kbit total); enables 36-bit parallel data paths for high-throughput inter-processor communication.
Cycle Time (Pipelined)	7.5 ns min (133 MHz operation); supports 9.6 Gbps aggregate bandwidth across both ports.
Max Clock-to-Data (tCD2)	5 ns (industrial grade); guarantees deterministic read latency for time-critical control loops.
I/O Voltage Options	Selectable 3.3 V (±150 mV) or 2.5 V (±125 mV) per port via OPTL/OPTR; eliminates level-shifter components in mixed-voltage designs.
Operating Temperature	−40°C to +85°C; validated for industrial embedded applications including base station radios and motor drive controllers.
Power Supply	3.3 V ±150 mV core (VDD); independent VDDQL/VDDQR supplies per port; enables dynamic I/O voltage scaling.
Standby Current (ISB3)	6 mA typ / 30 mA max (full standby, CMOS-level inputs); reduces idle power in always-on network buffers.

Pinout & Package

70V3569S5BFI8 is packaged in a 208-pin Plastic Quad Flatpack (PQFP) with 0.5 mm lead pitch and 28 mm × 28 mm body size. Pin assignments follow JEDEC MS-026 standard; all VDD pins require 3.3 V, VDDQL/VDDQR must match OPTL/OPTR logic state (3.3 V if VIH, 2.5 V if VIL), and all VSS pins connect to ground.

Pin/Terminal	Circuit Role	Design Meaning
CLKL / CLKR	Port-synchronous clock inputs	Register all address/data/control on rising edge; enable strict timing closure in FPGA-ASIC co-designs.
A0L–A13L / A0R–A13R	14-bit address buses (left/right)	Address 16K locations (2¹⁴ = 16,384); no external address latches required due to input registers.
I/O0L–I/O35L / I/O0R–I/O35R	36-bit bidirectional data buses	Supports full 36-bit transfers or byte-selectable 9-bit writes via BE0–BE3; avoids bus contention in shared-memory topologies.
BE0L–BE3L / BE0R–BE3R	Byte enable controls (9-bit granularity)	Enables partial-word writes without read-modify-write; essential for protocol header updates in packet processors.
OPTL / OPTR	I/O voltage selection inputs	Set VIH (3.3 V) or VIL (0 V) to configure corresponding VDDQ supply voltage; allows asymmetric port interfacing.
CNTRSTL / CNTRSTR	Asynchronous counter reset	Resets internal address counter to 0 on active-low assertion; enables deterministic buffer restart after error recovery.

Key Features

Feature	Design Value
True dual-port memory cells	Enables concurrent read and write to identical addresses - critical for lock-free inter-processor communication in real-time OS environments.
Pipelined output mode	1-cycle output latency with tCD2 ≤ 5 ns; eliminates pipeline stalls in high-frequency data streaming pipelines.
Dual chip enables (CE0/CE1 per port)	Allows seamless depth expansion (e.g., 32K×36) using multiple devices without external decode logic or glue ICs.
Separate byte controls (BE0–BE3)	Permits atomic 9-bit field updates in protocol stacks (e.g., Ethernet MAC header modification) without corrupting adjacent bytes.
Counter enable & reset (CNTEN/CNTRST)	Generates sequential addresses internally - reduces host CPU overhead in circular buffer or DMA descriptor management.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-port SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C1362BV33-5BC	512K × 18 organization, 5 ns access, 2.5 V only I/O, 256-ball BGA package	Higher density but narrower 18-bit bus; requires two devices for 36-bit width; no OPT pin for voltage selection	Choose when board space permits BGA and system demands >2× memory depth over width.
IDT70V27L25PF8	8K × 18 organization, 25 ns access, 3.3 V only I/O, PQFP-128 package	Lower speed, half the density and width; lacks pipelined output and counter features	Acceptable only for non-real-time legacy control systems where cost outweighs performance.

Compared with CY7C1362BV33-5BC and IDT70V27L25PF8, the 70V3569S5BFI8 uniquely delivers 16K × 36 width-matched organization, industrial-temperature 5 ns pipelined access, and per-port I/O voltage flexibility - making it irreplaceable in new designs requiring deterministic low-latency dual-port buffering.

FAQ

What is the maximum operating frequency of the 70V3569S5BFI8?

The 70V3569S5BFI8 supports up to 133 MHz operation with a minimum 7.5 ns clock cycle time in pipelined mode. This is validated across the full industrial temperature range (−40°C to +85°C) and confirmed in the AC Electrical Characteristics table (tCYC2 = 7.5 ns min) of the official datasheet revision DSC 4831/15.

Does the 70V3569S5BFI8 support independent I/O voltage selection on each port?

Yes, the 70V3569S5BFI8 supports independent I/O voltage selection per port via OPTL and OPTR pins. Setting OPTL to VIH (3.3 V) configures VDDQL for 3.3 V operation; setting it to VIL (0 V) configures VDDQL for 2.5 V. The same applies to OPTR/VDDQR. This capability is explicitly documented in Truth Table II and DC Operating Conditions tables.

What package type is used for the 70V3569S5BFI8?

The 70V3569S5BFI8 uses a 208-pin Plastic Quad Flatpack (PQFP) package, designated DRG208 in IDT documentation. Its mechanical dimensions are approximately 28 mm × 28 mm × 3.5 mm with 0.5 mm lead pitch, and it complies with JEDEC MS-026 standards - confirmed in Pin Configuration pages 4–5 of datasheet DSC 4831/15.

How does the address counter function in the 70V3569S5BFI8?

The 70V3569S5BFI8 includes independent address counters on both ports, controlled by CNTENL/CNTENR and CNTRSTL/CNTRSTR. When CNTEN = VIL on the rising CLK edge, the counter advances automatically - eliminating host CPU address increment overhead. Counter operation is detailed in Truth Table II and Timing Waveform drw 11–14.

Is the 70V3569S5BFI8 compatible with both commercial and industrial temperature ranges?

The 70V3569S5BFI8 is qualified for industrial temperature operation (−40°C to +85°C) and is explicitly marked "S5" in its part number to denote this grade. The "S4" and "S6" variants are commercial-only; the "S5" suffix confirms full industrial qualification, including AC/DC parameter validation across the full range as shown in Tables 09 and 11.
