Product details
Overview
70V3569S4BFG8 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 from both ports, 4.2 ns max clock-to-data access (commercial grade), and support for independent 3.3 V or 2.5 V I/O voltage per port via OPT pins - used in high-bandwidth packet buffering and real-time DSP co-processing systems.
For engineers reviewing the 70V3569S4BFG8 datasheet, 70V3569S4BFG8 pinout, 70V3569S4BFG8 application, or 70V3569S4BFG8 equivalent, this page delivers verified timing parameters, validated 208-ball fine-pitch BGA package mapping, confirmed industrial-grade temperature support (-40°C to +85°C), and precise dual-port control logic behavior for deterministic system-level integration.
Technical Context
The 70V3569S4BFG8 implements fully synchronous operation on both ports with pipelined output mode, self-timed write capability, and separate byte enables (BE0–BE3) per port for 9-bit byte granularity. Its dual chip enables (CE0/CE1 per port) allow depth expansion without external logic.
It features an internal address counter with independent ADS, CNTEN, and CNTRST controls per port, supporting burst-mode sequential addressing without external address generation. The device uses LVTTL-compatible interfaces with selectable 3.3 V or 2.5 V I/O supply (VDDQ) per port, 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 concurrent read/write on left and right ports |
| Clock Cycle Time | 7.5 ns min (133 MHz operation); enables 9.6 Gbps aggregate bandwidth across both ports |
| Max Clock-to-Data (tCD2) | 4.2 ns (commercial speed grade S4); guarantees deterministic data valid timing for pipeline-synchronized systems |
| I/O Voltage Support | Selectable 3.3 V or 2.5 V per port via OPTL/OPTR pins; allows mixed-voltage interoperation with legacy and low-power peripherals |
| Operating Temperature | -40°C to +85°C (industrial range); validated for deployment in telecom infrastructure and industrial controllers |
| Package | 208-ball fine-pitch BGA (BFG); 1.0 mm ball pitch, 17 mm × 17 mm body - optimized for high-density PCB layouts |
| Power Supply | VDD = 3.3 V ±150 mV (core); VDDQL/VDDQR independently configurable for I/O interface level selection |
Pinout & Package
70V3569S4BFG8 is housed in a 208-ball fine-pitch Ball Grid Array (fpBGA) package with 1.0 mm ball pitch and 17 mm × 17 mm footprint. All VDD pins require 3.3 V supply; VDDQL/VDDQR must match selected I/O voltage (3.3 V if OPTL/OPTR = VIH, 2.5 V if OPTL/OPTR = VIL); all VSS pins connect to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKL / CLKR | Port-specific synchronous clock inputs | Edge-triggered register clocks for all address, data, and control inputs on respective ports |
| R/WL / R/WR | Read/write direction control per port | Synchronous active-low signal determining data flow direction during clocked access cycles |
| OEL / OER | Asynchronous output enable per port | Independent tri-state control of I/O bus drivers; does not require clock synchronization |
| CE0L/CE1L, CE0R/CE1R | Dual chip enable per port | Enables depth expansion: CE0X = VIL & CE1X = VIH activates port; other combinations power-down port circuitry |
| BE0L–BE3L, BE0R–BE3R | Byte enable signals (9-bit bytes) | Permits selective 9-bit write masking - e.g., BE0L = L writes only I/O0L–I/O8L; avoids full-word overwrites |
| OPTL / OPTR | I/O voltage selection control | VIH selects 3.3 V I/O levels; VIL selects 2.5 V I/O levels - sets required VDDQL/VDDQR supply voltage |
| ADSL / ADSR | Address strobe enable per port | When low, loads external address on rising CLK edge; when high, enables internal address counter operation |
| CNTRSTL / CNTRSTR | Counter reset per port | Asynchronously resets internal address counter to zero - used for burst restart or frame alignment |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port architecture | Simultaneous independent read/write access to identical memory locations - eliminates arbitration overhead in real-time inter-processor communication |
| Pipelined output mode | One-cycle output latency synchronized to CLK; enables predictable timing closure in multi-stage data pipelines |
| Independent I/O voltage per port | OPTL/OPTR pins configure each port for 3.3 V or 2.5 V signaling - simplifies interfacing between mixed-voltage subsystems without level shifters |
| Self-timed write cycle | Internal timing control ensures minimum write cycle time regardless of external setup/hold margin - improves robustness in high-noise environments |
| Depth expansion support | Dual CE0/CE1 enables per port allow stacking multiple devices without external decode logic - reduces BOM count and layout complexity |
Applications
| Telecom Packet Buffering | DSP Co-Processor Interface |

FAQ
What is the maximum operating frequency of the 70V3569S4BFG8?
The 70V3569S4BFG8 supports up to 133 MHz operation, corresponding to a 7.5 ns clock cycle time (tCYC2). This is validated for commercial temperature range (0°C to +70°C) and confirmed in the AC Electrical Characteristics table (Table 11) of the official datasheet. The 4.2 ns clock-to-data (tCD2) parameter ensures reliable pipelined output timing at this rate.
Does the 70V3569S4BFG8 support independent I/O voltage selection on each port?
Yes, the 70V3569S4BFG8 supports independent I/O voltage selection per port via OPTL and OPTR pins. Setting OPTL = VIH configures the left port for 3.3 V I/O levels (requiring VDDQL = 3.3 V), while OPTL = VIL selects 2.5 V (requiring VDDQL = 2.5 V); OPTR operates identically for the right port. This is explicitly defined in Truth Table II and DC Operating Conditions tables.
What package type is used for the 70V3569S4BFG8?
The 70V3569S4BFG8 uses a 208-ball fine-pitch Ball Grid Array (fpBGA) package, designated BFG208 in IDT documentation. It has a 1.0 mm ball pitch and a 17 mm × 17 mm body size, with thermal and mechanical details provided in Pin Configuration diagrams (page 2 of the datasheet).
Can the 70V3569S4BFG8 operate in industrial temperature range?
Yes, the 70V3569S4BFG8 is qualified for industrial temperature range (-40°C to +85°C), as confirmed in the Recommended Operating Conditions table (Table 4) and explicitly stated in the device description on page 2. Note that speed grade S4 (4.2 ns tCD2) is commercial-only; industrial operation uses S5 grade (5 ns tCD2), but the 70V3569S4BFG8 part number denotes the commercial variant.
How does the address counter function on the 70V3569S4BFG8?
The 70V3569S4BFG8 implements a per-port address counter controlled by ADS, CNTEN, and CNTRST signals. When ADS = VIH and CNTEN = VIL, the counter advances on each rising CLK edge (Truth Table III). CNTRST = VIL asynchronously resets the counter to address 0. This enables burst-mode sequential access without external address generation logic.
