Product details
Overview
70V3569S5DRI from Integrated Device Technology is a high-speed 16K × 36-bit synchronous dual-port static RAM with pipelined output, 7.5 ns cycle time (133 MHz), true dual-port architecture enabling simultaneous read/write access to the same memory location, and independent 3.3 V or 2.5 V I/O voltage selection per port - used in high-bandwidth packet buffering for telecom line cards and FPGA co-processor interfaces.
For engineers reviewing the 70V3569S5DRI datasheet, 70V3569S5DRI pinout, 70V3569S5DRI application, or 70V3569S5DRI equivalent, this page delivers verified timing parameters, industrial-grade (-40°C to +85°C) operation, PQFP-208 package mapping, byte-enable granularity, and synchronous counter/ADS control logic essential for deterministic latency design in real-time data path systems.
Technical Context
The 70V3569S5DRI implements fully synchronous dual-port operation on both left and right ports, with all inputs (address, data, control) registered on rising clock edges and pipelined outputs delayed by one clock cycle. It supports independent address strobe (ADSL/ADSR) and counter enable/reset (CNTENL/CNTRSTL, CNTENR/CNTRSTR) per port for burst-mode sequential addressing without external logic.
Each port features separate 3.3 V core supply (VDD) and selectable 3.3 V/2.5 V I/O supplies (VDDQL/VDDQR) controlled by OPTL/OPTR pins, enabling mixed-voltage system interfacing. Dual chip enables (CE0X/CE1X) allow depth expansion without additional decoding logic, and four independent byte enables (BE0–BE3) support 9-bit byte masking per port.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 36 bits (576 Kbit total); supports concurrent left/right port access to identical addresses without arbitration delay. |
| Cycle Time (Pipelined) | 7.5 ns (133 MHz); enables 9.6 Gbps aggregate bandwidth across both ports with zero wait-state operation. |
| Access Time (tCD2) | 5 ns max (industrial grade); defines worst-case clock-to-data-out latency for timing-critical pipeline stages. |
| Supply Voltages | VDD = 3.3 V ±150 mV (core); VDDQ = 3.3 V ±150 mV or 2.5 V ±125 mV per port - allows direct interface to 2.5 V FPGAs or 3.3 V ASICs. |

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, TQFP-100 package (smaller footprint but lower speed and no 2.5 V option). | Limited to 3.3 V systems; lacks per-port voltage select and counter/ADS features - suitable only for simpler, lower-bandwidth designs. | Select when board space is constrained and 133 MHz timing is not required; verify compatibility with existing 3.3 V-only signal chains. |
| AS7C331664B-100BIN | 16K × 36, 100 MHz, 3.3 V core/I/O, 256-ball BGA package - higher pin count, no byte enable granularity or counter mode. | No independent byte enables or address counter; requires external logic for burst addressing - increases BOM and layout complexity. | Choose only if BGA assembly infrastructure exists and per-byte write masking is unnecessary; avoid for latency-sensitive or mixed-voltage designs. |
