Product details

Overview

70V3379S6BF8 from Integrated Device Technology is a high-speed 32K × 18-bit synchronous dual-port static RAM with pipelined output, 3.3V core supply, and independently configurable 3.3V/2.5V I/O interfaces per port. It supports simultaneous read/write access to the same memory location, delivers 4.2ns clock-to-data (pipelined), and operates at 133MHz with 7.5ns cycle time for 9.6 Gbps aggregate bandwidth in telecom switching and network packet buffering applications.

For engineers reviewing the 70V3379S6BF8 datasheet, 70V3379S6BF8 pinout, 70V3379S6BF8 application, or 70V3379S6BF8 equivalent, key selection considerations include dual-port latency matching, independent VDDQ voltage selection per port via OPT pins, counter-enable/reset functionality for burst address sequencing, and industrial-grade thermal stability up to +85°C in the 208-pin fpBGA package.

Technical Context

The 70V3379S6BF8 implements true dual-port SRAM cells with fully synchronous register-controlled inputs on both ports-address, data, and control signals all latch on the rising edge of CLKL/CLKR. Its pipelined output mode introduces one-cycle latency but enables deterministic 133MHz operation with 1.8ns address setup and 0.7ns hold timing.

Each port features independent power domains: fixed 3.3V VDD core and selectable 3.3V/2.5V VDDQ I/O supplies controlled by OPTL/OPTR pins. The integrated address counter (CNTENL/CNTRSTL and CNTENR/CNTRSTR) allows autonomous sequential addressing without external logic, supporting burst-mode packet processing in FPGA-based line cards.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Organization	32K × 18 bits (576 Kbit total); enables 18-bit parallel data paths per port for high-throughput packet header storage.
Clock Cycle Time (Pipelined)	12 ns min (70V3379S6 grade); supports 83.3 MHz sustained operation with guaranteed timing margin for PCB trace skew.
Clock-to-Data Valid (tCD2)	6 ns max; defines worst-case latency from CLK rise to valid Q output in pipelined read mode.
I/O Supply Voltage (VDDQ)	Selectable 3.3 V ±150 mV or 2.5 V ±125 mV per port via OPT pin; allows mixed-voltage system integration with 2.5V FPGAs and 3.3V processors.
Operating Temperature Range	0°C to +70°C (Commercial grade); validated for stable operation in fan-cooled telecom chassis environments.
Package	208-pin fine-pitch Ball Grid Array (fpBGA, BF208); 17 mm × 17 mm body with 1.0 mm ball pitch for high-density routing and thermal dissipation.
Dynamic Current (IDD)	310 mA max at fMAX (83.3 MHz); enables accurate power budgeting for multi-device memory banks in line interface units.

Pinout & Package

70V3379S6BF8 is housed in a 208-pin fpBGA (BF208) package with 17 mm × 17 mm footprint and 1.0 mm ball pitch. Power and ground balls are distributed across the array for low-impedance decoupling; VDD (3.3 V core) and VDDQ (3.3 V/2.5 V I/O) are segregated per port to minimize noise coupling.

Pin/Terminal	Circuit Role	Design Meaning
CLKL / CLKR	Port-synchronous clock inputs	Independent rising-edge-triggered clocks enable asynchronous timing domains between left/right ports for glueless FPGA–ASIC interfacing.
A0L–A14L / A0R–A14R	15-bit address buses	32K depth requires 15 address bits; ADSL/ADSR strobes allow address latching independent of counter mode.
I/O0L–I/O17L / I/O0R–I/O17R	18-bit bidirectional data buses	Split into upper/lower 9-bit bytes (UB/LB) for byte-selective writes; supports multiplexed bus compatibility.
CE0L/CE1L / CE0R/CE1R	Dual chip enables per port	Two independent enables allow depth expansion without external logic; CE0=LOW + CE1=HIGH powers down port circuitry to reduce standby current.
OPTL / OPTR	I/O voltage select inputs	TTL-level control pins that configure VDDQL/VDDQR supply domain: VIH = 3.3 V, VIL = 2.5 V; enables mixed-voltage board design.
CNTENL/CNTRSTL / CNTENR/CNTRSTR	Address counter controls	Enable/disable and reset internal 15-bit address counter for burst-mode sequential access without host CPU intervention.

Key Features

Feature	Design Value
True dual-port memory cells	Enables concurrent read and write to identical addresses-critical for real-time FIFOs in packet inspection engines.
Pipelined output mode	Guarantees 12 ns minimum cycle time at 83.3 MHz with deterministic 6 ns tCD2 latency for timing-critical control plane buffers.
Independent VDDQ selection per port	Allows left port to interface with 2.5 V FPGA I/O while right port connects to 3.3 V microcontroller-eliminates level-shifter components.
Integrated address counter	Reduces host processor overhead in burst transfers: CNTEN assertion auto-increments address on each clock, enabling zero-wait-state streaming.
Asynchronous output enable (OEL/OER)	Permits dynamic tri-state control of data buses during bus arbitration without disrupting clock-domain synchronization.
Full synchronous operation	All inputs registered on CLK rise edge; eliminates setup/hold violations in high-speed backplane designs with >100 ps jitter budgets.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY7C1375BV33-167AXC	167 MHz max frequency (6 ns tCD2), 32K × 18 organization, 3.3 V only I/O (no 2.5 V option), 100-pin TQFP package	Lacks independent VDDQ selection and address counter; requires external logic for burst addressing	Choose when maximum speed (167 MHz) is required and board layout accommodates TQFP; avoid if mixed-voltage I/O or counter automation is needed.
AS7C33256P-15JIN	15 ns access time (asynchronous), 32K × 18, 3.3 V core/I/O, 128-pin TQFP; no pipelining, no counter, no dual VDDQ	Asynchronous interface increases timing uncertainty; no clock-domain isolation between ports	Choose only for cost-sensitive legacy designs where synchronous timing constraints are relaxed and FPGA resources are unavailable for counter logic.

Compared with CY7C1375BV33-167AXC and AS7C33256P-15JIN, the 70V3379S6BF8 uniquely combines pipelined 133 MHz operation, per-port VDDQ voltage selection, and integrated address counter-enabling lower system BOM cost, reduced FPGA logic utilization, and deterministic latency in high-speed packet processing systems.

FAQ

What is the maximum operating frequency of the 70V3379S6BF8?

The 70V3379S6BF8 supports a minimum clock cycle time of 12 ns, enabling reliable operation at 83.3 MHz in pipelined mode. This is specified for the "S6" speed grade under commercial temperature conditions (0°C to +70°C) with full timing compliance including 1.8 ns address setup and 0.7 ns hold margins.

Does the 70V3379S6BF8 support independent I/O voltage levels on left and right ports?

Yes, the 70V3379S6BF8 supports independent I/O voltage selection per port via OPTL and OPTR pins. Setting OPTL to VIH configures VDDQL for 3.3 V operation, while VIL selects 2.5 V; the same applies to OPTR and VDDQR. This allows mixed-voltage system integration without external level shifters.

How does the address counter function in the 70V3379S6BF8?

The 70V3379S6BF8 integrates a 15-bit address counter per port controlled by CNTENL/CNTRSTL (left) and CNTENR/CNTRSTR (right). When CNTEN = VIL on CLK rise, the counter advances automatically-enabling burst-mode sequential access without host address updates. CNTRST resets to address 0 synchronously.

What package type is used for the 70V3379S6BF8?

The 70V3379S6BF8 uses a 208-pin fine-pitch Ball Grid Array (fpBGA) package designated BF208. It measures 17 mm × 17 mm with 1.0 mm ball pitch and is optimized for high-density PCB layouts and thermal performance in telecom line cards.

Is the 70V3379S6BF8 compatible with industrial temperature ranges?

No, the 70V3379S6BF8 is rated for commercial temperature range only (0°C to +70°C). For industrial operation (-40°C to +85°C), the 70V3379S5 variant is specified-identifiable by the "S5" suffix in the part number and validated across the extended thermal envelope.
