Product details

Overview

70V3569S5BCI 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 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 - deployed in real-time packet buffering for telecom line cards and FPGA co-processor data exchange.

For engineers reviewing the 70V3569S5BCI datasheet, 70V3569S5BCI pinout, 70V3569S5BCI application, or 70V3569S5BCI equivalent, this page delivers verified timing parameters, industrial-grade thermal validation (−40°C to +85°C), PQFP-208 package mapping, byte-enable granularity for burst-mode bus matching, and confirmed alternatives for depth-expansion or voltage-flexible system upgrades.

Technical Context

The 70V3569S5BCI implements fully synchronous operation on both ports with registered address, data, and control inputs - enabling 133 MHz operation (7.5 ns cycle time) and 9.6 Gbps aggregate bandwidth. Its pipelined output mode introduces one-cycle latency but guarantees deterministic timing across temperature and voltage corners.

It features independent address counters per port with ADS strobe enable, CNTEN/CNTRST controls, and dual chip enables (CE0/CE1) that allow seamless depth expansion without external logic. The OPTL/OPTR pins configure per-port I/O voltage (3.3 V or 2.5 V), while core VDD remains fixed at 3.3 V ±150 mV.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Organization	16K × 36 bits (576 Kbit total); supports independent read/write on left/right ports simultaneously
Access Time (tCD2)	5 ns max (industrial temp); defines guaranteed data valid window after rising clock edge in pipelined mode
Cycle Time (tCYC2)	7.5 ns min; enables 133 MHz sustained operation with full setup/hold compliance at −40°C to +85°C
I/O Voltage Flexibility	Selectable 3.3 V or 2.5 V per port via OPTL/OPTR pins; allows mixed-voltage system interfacing without level shifters
Byte Enable Granularity	Four 9-bit BE0–BE3 signals per port; enables precise 1-, 2-, or 4-byte writes without read-modify-write overhead
Power Management	Four standby modes (ISB1–ISB4); ISB3 draws only 6 mA typ when both ports fully disabled with CMOS-level inputs
Operating Temperature	−40°C to +85°C (industrial grade); validated across full speed bin (70V3569S5) with no derating required

Pinout & Package

70V3569S5BCI 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 selection (3.3 V if OPT = VIH, 2.5 V if OPT = VIL).

Pin/Terminal	Circuit Role	Design Meaning
CLKL / CLKR	Port-synchronous clock inputs	Rising-edge-triggered; all registers (address, data, control) sample on these clocks - critical for deterministic pipelined timing
A0L–A13L / A0R–A13R	14-bit address buses	Supports 16K (2¹⁴) addresses per port; ADSL/ADSR strobes load address on rising CLK edge
I/O0L–I/O35L / I/O0R–I/O35R	36-bit bidirectional data buses	Each port handles full 36-bit word; byte enables (BE0–BE3) partition into four 9-bit lanes for partial writes
BE0L–BE3L / BE0R–BE3R	Byte enable controls	Active-low; selects which 9-bit byte(s) are written - enables efficient burst transfers without bus contention
R/WL / R/WR	Read/write direction control	High = read, low = write; synchronous to respective port clock - determines data flow direction per access
OEL / OER	Asynchronous output enable	Independent per port; tri-states outputs immediately (no clock dependency), enabling shared-bus arbitration
CE0L/CE1L / CE0R/CE1R	Dual chip enables	Enable/disable port activity; CE0=low + CE1=high activates port - allows depth expansion using multiple devices
OPTL / OPTR	I/O voltage select	Tie to VDD (3.3 V) for 3.3 V I/O, or to VSS (0 V) for 2.5 V I/O - configures VDDQL/VDDQR supply requirements

Key Features

Feature	Design Value
True dual-port memory cells	Enables concurrent read/write to identical address locations - essential for lock-free inter-processor communication
Pipelined output architecture	Guarantees fixed 1-cycle latency from clock to valid data, eliminating timing uncertainty in high-frequency pipelines
Per-port I/O voltage selection	Eliminates need for external level shifters when interfacing with 2.5 V FPGAs or 3.3 V ASICs on same board
Independent address counters	Reduces host CPU overhead by auto-advancing address on each access - ideal for streaming FIFO or DMA buffer applications
Four-tier standby power management	ISB3 mode draws just 6 mA typ with both ports fully disabled - extends uptime in thermally constrained industrial gateways
Dual chip enables (CE0/CE1)	Enables seamless depth expansion up to 64K × 36 using multiple 70V3569S5BCI devices without glue logic

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	5 ns access, 16K × 36, 3.3 V only I/O (no 2.5 V option), PQFP-208 package	Lacks per-port voltage flexibility; requires external level shifters for mixed-voltage systems	Choose when system uses only 3.3 V peripherals and cost sensitivity outweighs design flexibility
AS7C3316PFS-55BIN	5.5 ns access, 16K × 36, 3.3 V core/I/O, 256-ball BGA (not PQFP)	Different footprint and thermal profile; no OPT pin - fixed 3.3 V I/O interface	Choose for space-constrained designs where BGA routing and higher density justify re-layout

Compared with CY7C1362BV33-5BC and AS7C3316PFS-55BIN, the 70V3569S5BCI uniquely supports independent 2.5 V/3.3 V I/O per port and retains PQFP-208 compatibility - delivering voltage flexibility without sacrificing layout reuse or thermal manageability in industrial control systems.

FAQ

What is the maximum operating frequency of the 70V3569S5BCI?

The 70V3569S5BCI supports 133 MHz operation with a minimum 7.5 ns clock cycle time, validated across the full industrial temperature range (−40°C to +85°C). This frequency is achievable under specified conditions: VDD = 3.3 V ±150 mV, VDDQ = 2.5 V or 3.3 V per port, and all AC timing parameters met per datasheet Table 11. The device maintains this performance without derating.

Does the 70V3569S5BCI support true simultaneous read/write on both ports?

Yes, the 70V3569S5BCI uses true dual-port memory cells that allow independent, concurrent read and write operations to the same memory address - a key differentiator from pseudo-dual-port or queue-based buffers. This capability is hardware-guaranteed and does not rely on arbitration logic or software coordination.

How does the OPTL and OPTR pin configuration affect power supply requirements for the 70V3569S5BCI?

OPTL and OPTR independently select I/O voltage per port: VIH (3.3 V) requires VDDQL/VDDQR = 3.3 V ±150 mV; VIL (0 V) requires VDDQL/VDDQR = 2.5 V ±125 mV. Core VDD remains fixed at 3.3 V ±150 mV regardless of OPT setting. Incorrect VDDQ–OPT pairing causes functional failure or excessive leakage.

What is the purpose of the ADSL and ADSR pins on the 70V3569S5BCI?

ADSL and ADSR are asynchronous address strobe inputs that load the current address bus value into the internal address register on the next rising edge of CLKL or CLKR. When ADS = VIL, the external address is latched; when ADS = VIH, the internal address counter (if enabled) continues incrementing - enabling flexible addressing modes without CPU intervention.

Can the 70V3569S5BCI be used in depth-expanded configurations without additional logic?

Yes, the 70V3569S5BCI includes dual chip enables (CE0 and CE1) per port, allowing up to four devices to be cascaded for depth expansion (e.g., 64K × 36) using only address-line decoding - no external gates or CPLDs required. CE0 = low + CE1 = high activates the port; other combinations place it in power-down or high-Z states.
