Product details

Overview

70V3569S5DR from Integrated Device Technology is a high-speed 16K × 36-bit synchronous dual-port static RAM with pipelined output, true dual-port memory cells enabling simultaneous access to the same address, 7.5 ns cycle time (133 MHz), and selectable 3.3 V or 2.5 V I/O interface per port - used in high-bandwidth packet buffering and real-time DSP co-processor memory subsystems.

For engineers reviewing the 70V3569S5DR datasheet, 70V3569S5DR pinout, 70V3569S5DR application, or 70V3569S5DR equivalent, key selection criteria include pipelined read latency, independent port voltage configuration (via OPTL/OPTR), counter-enabled burst addressing, and industrial temperature support (−40°C to +85°C) in PQFP and BGA packages.

Technical Context

The 70V3569S5DR implements full synchronous operation on both ports using edge-triggered registers for address, data, and control inputs - achieving 1.8 ns setup and 0.7 ns hold times at 133 MHz. Its pipelined output mode introduces one-cycle latency between clock and valid data, while self-timed write enables minimal cycle time without external timing control.

Each port features independent chip enables (CE0/CE1), byte enables (BE0–BE3), address strobe (ADS), counter enable (CNTEN), and counter reset (CNTRST) - allowing depth expansion, burst-mode sequential access, and asynchronous output enable (OE) for bus sharing without additional logic.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Organization	16K × 36 bits - provides 576 Kbit total capacity with 36-bit wide data path per port for parallel word-level transfers.
Cycle Time (Pipelined)	7.5 ns - supports 133 MHz clock rate, enabling 9.6 Gbps aggregate bandwidth across both ports.
Access Time (Clock to Data)	5 ns max - guarantees deterministic 5 ns output valid delay after rising clock edge in pipelined read mode.
I/O Voltage Support	Selectable 3.3 V or 2.5 V per port via OPTL/OPTR pins - allows mixed-voltage system interfacing without level shifters.
Operating Temperature	−40°C to +85°C - qualified for industrial environments including telecom line cards and industrial controllers.
Power Supply	Core: 3.3 V ±150 mV; I/O: 3.3 V ±150 mV or 2.5 V ±125 mV - decoupled core/I/O rails reduce noise coupling.
Standby Current (ISB3)	6 mA typ. - ultra-low full standby current when both ports disabled with CMOS-level inputs, critical for power-sensitive systems.

Pinout & Package

70V3569S5DR is available in a 208-pin Plastic Quad Flatpack (PQFP) package with 0.5 mm lead pitch and body size ≈28 mm × 28 mm × 3.5 mm. Pin functions are symmetrically organized for left (L) and right (R) ports, with dedicated VDD/VSS, address, data I/O, control, and option pins.

Pin/Terminal	Circuit Role	Design Meaning
CLKL / CLKR	Port-synchronous clock input	Edge-triggered register clock for all inputs and outputs on respective port; enables fully synchronous timing at 133 MHz.
A0L–A13L / A0R–A13R	Address inputs	14-bit address bus per port - selects one of 16K locations; ADSL/ADSR allows address latching independent of counter.
I/O0L–I/O35L / I/O0R–I/O35R	Bidirectional data I/O	36-bit parallel data path per port; BE0–BE3 enable 9-bit byte granularity for partial writes without read-modify-write.
OPTL / OPTR	I/O voltage select	Logic-level input controlling VDDQL/VDDQR supply voltage - VIH = 3.3 V, VIL = 2.5 V; enables mixed-voltage interoperation.
CNTRSTL / CNTRSTR	Counter reset	Asynchronous reset of internal address counter to zero - enables deterministic burst start without external address generation.
CNTENL / CNTENR	Counter enable	Enables automatic address increment on each clock edge - supports sequential burst access without host address updates.

Key Features

Feature	Design Value
True dual-port memory cells	Enables concurrent read/write access to identical addresses - eliminates arbitration overhead in shared-memory multiprocessor designs.
Pipelined output mode	Guarantees 5 ns max clock-to-data delay with one-cycle latency - simplifies timing closure in high-speed synchronous systems.
Dual chip enables (CE0/CE1)	Supports depth expansion up to 4× without external logic - reduces board space and signal routing complexity in large memory arrays.
Separate byte controls (BE0–BE3)	Allows 9-bit sub-word writes within 36-bit word - avoids destructive read-modify-write cycles and improves write efficiency.
Independent port I/O voltage selection	Per-port OPT pin configures VDDQ to 3.3 V or 2.5 V - enables direct interfacing with legacy 3.3 V and modern low-voltage 2.5 V logic families.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C1362BV33-100AXC	16K × 36, 100 MHz max, 3.3 V only I/O, no OPT pin or 2.5 V support	Lacks per-port voltage flexibility and counter features; requires external level translation for 2.5 V systems	Choose when 100 MHz speed suffices and system uses uniform 3.3 V I/O.
AS7C331636B-10BIN	16K × 36, 10 ns access, commercial-only (0°C to +70°C), no pipelined mode	No pipelining or counter functionality; not rated for industrial temperature range	Choose for cost-sensitive commercial applications where 133 MHz and extended temp are unnecessary.

Compared with CY7C1362BV33-100AXC and AS7C331636B-10BIN, the 70V3569S5DR uniquely delivers 133 MHz pipelined operation, per-port 2.5 V/3.3 V I/O selection, and integrated address counter - making it the only option supporting industrial-grade burst-buffering in mixed-voltage embedded systems.

FAQ

What is the maximum operating frequency of the 70V3569S5DR?

The 70V3569S5DR supports a maximum clock frequency of 133 MHz, corresponding to a 7.5 ns pipelined cycle time. This specification is guaranteed over the full industrial temperature range (−40°C to +85°C) and applies to both ports simultaneously under proper signal integrity and power delivery conditions.

Does the 70V3569S5DR support independent I/O voltage levels on its two ports?

Yes, the 70V3569S5DR supports independent I/O voltage selection per port via the OPTL and OPTR pins. Setting OPTL to VIH configures the left port for 3.3 V I/O operation (VDDQL = 3.3 V), while setting it to VIL configures it for 2.5 V (VDDQL = 2.5 V); the right port operates identically but independently using OPTR.

How does the address counter function work in the 70V3569S5DR?

The 70V3569S5DR includes an internal 14-bit address counter per port. When CNTENL (or CNTENR) is asserted low, the counter automatically increments on each rising CLKL (or CLKR) edge - enabling burst-mode sequential access without host-provided address updates. CNTRSTL/R resets the counter to zero asynchronously.

What package options are available for the 70V3569S5DR?

The 70V3569S5DR is offered in three package variants: 208-pin Plastic Quad Flatpack (PQFP), 208-ball fine-pitch Ball Grid Array (fpBGA), and 256-pin Ball Grid Array (BGA). The "S5DR" suffix specifically denotes the industrial-grade 208-pin PQFP variant with −40°C to +85°C operation.

Is the 70V3569S5DR pin-compatible with other members of the 70V3569 family?

Yes, all 70V3569 variants - including 70V3569S4, 70V3569S5, and 70V3569S6 - share identical pinouts across PQFP, fpBGA, and BGA packages. Speed grade differences (4.2 ns / 5 ns / 6 ns access) and temperature grades do not affect mechanical or electrical pin assignment.
