Product details
Overview
70V3569S4BC8 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 70V3569S4BC8 datasheet, 70V3569S4BC8 pinout, 70V3569S4BC8 application, or 70V3569S4BC8 equivalent, this page delivers verified timing parameters, dual-port control logic behavior, industrial-grade (-40°C to +85°C) operation, and PQFP-208 package implementation details critical for deterministic latency design in real-time data path systems.
Technical Context
The 70V3569S4BC8 implements full synchronous operation on both ports using edge-triggered registers for address, data, and all 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 ≤ 4.2 ns under commercial conditions.
It supports independent voltage configuration per port via OPTL/OPTR pins, allowing mixed-voltage interfacing (e.g., 3.3 V left port to 2.5 V right port). The integrated address counter-with separate CNTENL/CNTRSTL and CNTENR/CNTRSTR signals-enables burst-mode sequential access without external sequencing logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 36 bits (576 Kbit); supports concurrent left/right port access to identical addresses |
| Clock Cycle Time | 7.5 ns (133 MHz); defines minimum clock period for full-speed pipelined operation |
| Max Clock-to-Data (tCD2) | 4.2 ns (commercial grade); determines worst-case latency from CLK rise to valid Q output |
| I/O Voltage Options | Selectable 3.3 V (±150 mV) or 2.5 V (±125 mV) per port via OPT pins; enables mixed-voltage system integration |
| Operating Temperature | -40°C to +85°C (industrial range); validated for sustained operation in base station and industrial controller environments |
| Power Supply | Core VDD = 3.3 V ±150 mV; separate VDDQ rails per port eliminate I/O voltage crosstalk |
| Standby Current (ISB3) | 6 mA typical (full standby, CMOS-level inputs); enables low-power idle states in always-on systems |
Pinout & Package
70V3569S4BC8 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 MO-145 standard; all VDD pins require 3.3 V supply, VDDQ pins must match OPT pin logic level (3.3 V if OPT = VIH, 2.5 V if OPT = VIL), and all VSS pins connect to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKL / CLKR | Left/Right Port Clock Inputs | Synchronous edge-trigger for all registered inputs; rising edge latches address, data, and controls |
| A0L–A13L / A0R–A13R | Address Inputs (14-bit) | 16K depth addressing; ADSL/ADSR enables asynchronous address strobe override of counter |
| I/O0L–I/O35L / I/O0R–I/O35R | Bidirectional Data I/O (36-bit) | Four 9-bit byte lanes (BE0–BE3); enables partial writes without read-modify-write overhead |
| R/WL / R/WR | Read/Write Control | Active-high write enable; synchronous to respective port clock; determines data flow direction per cycle |
| CE0L/CE1L / CE0R/CE1R | Dual Chip Enables | Depth expansion support: CE0X = VIL & CE1X = VIH enables port; both high disables port (power-down) |
| OEL / OER | Output Enable | Asynchronous control; overrides clock-synchronous output gating to force high-Z state immediately |
| OPTL / OPTR | I/O Voltage Select | DC logic level (VIH/VIL) configures corresponding VDDQ rail voltage and input thresholds per port |
| CNTRSTL / CNTRSTR | Counter Reset | Asynchronous reset of internal address counter to zero; enables burst restart without external logic |
Key Features

The 70V3569S4BC8 supports a maximum clock frequency of 133 MHz, corresponding to a 7.5 ns clock cycle time in pipelined mode. This is validated across the commercial temperature range (0°C to +70°C) and confirmed in AC Electrical Characteristics Table 11 of the datasheet. Operation at this speed requires adherence to specified setup/hold times for address, control, and data inputs.
Does the 70V3569S4BC8 support independent voltage operation on each port?
Yes, the 70V3569S4BC8 supports independent I/O voltage selection per port via OPTL and OPTR pins. Setting OPTL to VIH (3.3 V) configures the left port for 3.3 V I/O operation, while setting OPTR to VIL (0 V) configures the right port for 2.5 V I/O operation-enabling mixed-voltage system interfacing without external level shifters.
What package type is used for the 70V3569S4BC8?
The 70V3569S4BC8 is supplied in a 208-pin Plastic Quad Flatpack (PQFP) package, per the DRG208 package code. Its dimensions are approximately 28 mm × 28 mm × 3.5 mm with 0.5 mm lead pitch, and it complies with JEDEC MO-145 mechanical standards.
How does the address counter function in the 70V3569S4BC8?
The 70V3569S4BC8 integrates a programmable address counter per port, controlled by CNTENL/CNTENR (enable) and CNTRSTL/CNTRSTR (reset) signals. When CNTENX = VIL on the rising CLK edge, the counter advances automatically-eliminating the need for external address increment logic during burst transfers.
Is the 70V3569S4BC8 suitable for industrial temperature applications?
Yes, the 70V3569S4BC8 is qualified for industrial temperature operation from -40°C to +85°C.
