Product details

Overview

70V3569S5BC 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 read/write access to the same memory location, 7.5 ns cycle time at 133 MHz, and selectable 3.3 V or 2.5 V I/O interface per port-used in high-bandwidth packet buffering for telecom line cards and FPGA co-processor memory subsystems.

For engineers reviewing the 70V3569S5BC datasheet, 70V3569S5BC pinout, 70V3569S5BC application, or 70V3569S5BC equivalent, this page delivers verified timing parameters (tCD2 = 5 ns max), voltage configuration logic (OPTL/OPTR control), industrial-grade thermal operation (–40°C to +85°C), and package-specific pin mapping for the 208-pin PQFP variant.

Technical Context

The 70V3569S5BC implements fully synchronous operation on both ports with clocked address, data, and control registers-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 timing across temperature and voltage.

It supports independent voltage selection per port via OPTL/OPTR pins, allowing mixed-voltage interfacing (e.g., 3.3 V left port to 2.5 V right port). The internal address counter-enabled by CNTEN and reset by CNTRST-operates independently of CE/R/W states and advances on CLK rising edge when CNTEN = VIL.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Organization	16K × 36 bits (576 Kbit total); enables 36-bit parallel data paths for burst-mode DSP or network processor interfaces.
Cycle Time (Pipelined)	7.5 ns min (133 MHz); defines maximum sustained throughput without wait states in synchronous systems.
Clock-to-Data Valid (tCD2)	5 ns max (industrial grade); guarantees deterministic read latency for real-time pipeline synchronization.
I/O Voltage Support	Selectable 3.3 V (±150 mV) or 2.5 V (±125 mV) per port via OPT pins; eliminates level-shifter requirements in mixed-voltage SoC interconnects.
Operating Temperature	–40°C to +85°C; qualified for industrial embedded applications including base station control modules and industrial PLCs.
Power Supply	Core VDD = 3.3 V ±150 mV; separate VDDQ supplies per port; enables independent power domain management.
Standby Current (ISB3)	6 mA typ / 30 mA max (full standby, CMOS inputs); critical for low-power sleep modes in always-on communication equipment.

Pinout & Package

70V3569S5BC is packaged in a 208-pin Plastic Quad Flatpack (PQFP), body size 28 mm × 28 mm × 3.5 mm, 0.65 mm lead pitch. All VDD pins require 3.3 V supply; VDDQL/VDDQR must match OPTL/OPTR logic state (3.3 V if VIH, 2.5 V if VIL).

Pin/Terminal	Circuit Role	Design Meaning
CLKL / CLKR	Port-synchronous clock inputs	Edge-triggered register clocks for all address/data/control inputs on respective ports; no internal PLL-timing referenced directly to external clock source.
A0L–A13L / A0R–A13R	14-bit address buses	Directly select one of 16K (2¹⁴) memory locations per port; ADSL/ADSR enable asynchronous address latching independent of clock.
I/O0L–I/O35L / I/O0R–I/O35R	36-bit bidirectional data buses	Support byte-wise access via BE0–BE3 (9-bit bytes); allow partial writes without read-modify-write overhead.
CE0L/CE1L / CE0R/CE1R	Dual chip enable pairs	Enable depth expansion: CE0X = VIL & CE1X = VIH activates port; CE0X = VIH or CE1X = VIL forces full standby-no external logic needed for multi-chip stacks.
OPTL / OPTR	I/O voltage selection inputs	Set VDDQL/VDDQR operating voltage: VIH → 3.3 V, VIL → 2.5 V; must be stable before applying I/O signals to prevent bus contention.
CNTRSTL / CNTRSTR	Asynchronous counter reset	Force internal address counter to zero regardless of clock or CNTEN state; used for frame synchronization in streaming applications.

Key Features

Feature	Design Value
True dual-port memory cells	Enables concurrent read and write to identical addresses-critical for producer-consumer FIFOs in real-time signal processing pipelines.
Pipelined output mode	Guarantees fixed 1-cycle output latency (tCD2 = 5 ns max), simplifying timing closure in high-speed synchronous designs without dynamic delay compensation.
Separate byte enables (BE0–BE3)	Permits 9-bit granularity writes across 36-bit bus-reduces bus turnaround overhead and avoids unnecessary data corruption during partial updates.
Dual chip enables per port	Allows seamless depth expansion up to 64K × 36 using multiple devices without external decode logic or glue logic.
Self-timed write cycle	Eliminates need for external write pulse generation; internal timing ensures reliable write completion within tCYC2 window regardless of process/voltage/temp variation.

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, no OPT pin; tCD = 6.5 ns (non-pipelined)	Lacks pipelined output and mixed-voltage support; requires external level shifters for 2.5 V interfaces.	Choose when cost sensitivity outweighs need for 133 MHz operation or voltage flexibility.
AS7C3316PFS-10BIN	16K × 36, 10 ns cycle, 3.3 V core/I/O, no counter or ADS features; asynchronous OE only	No address counter, no pipelining, no dual CE scheme-requires external logic for depth expansion and burst addressing.	Choose for simpler, lower-speed legacy designs where feature set reduction is acceptable.

Compared with CY7C1362BV33-100AXC and AS7C3316PFS-10BIN, the 70V3569S5BC delivers higher bandwidth (133 vs. 100/100 MHz), deterministic pipelined latency, and per-port voltage configurability-making it optimal for next-generation telecom and real-time embedded systems requiring mixed-signal interoperability and precise timing control.

FAQ

What is the maximum operating frequency of the 70V3569S5BC?

The 70V3569S5BC supports a maximum operating frequency of 133 MHz, corresponding to a minimum clock cycle time of 7.5 ns in pipelined mode. This specification applies across the full industrial temperature range (–40°C to +85°C) and is guaranteed by the 70V3569S5BC datasheet timing table for tCYC2.

Does the 70V3569S5BC support mixed-voltage operation between its two ports?

Yes, the 70V3569S5BC 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 (VDDQL = 3.3 V), while OPTR = VIL configures the right port for 2.5 V (VDDQR = 2.5 V)-enabling direct interfacing with heterogeneous logic families without external level shifters.

How does the address counter function in the 70V3569S5BC?

The 70V3569S5BC includes an internal 14-bit address counter per port, enabled by CNTENL/CNTENR and reset by CNTRSTL/CNTRSTR. When CNTEN = VIL, the counter advances on each CLK rising edge regardless of CE or R/W state. ADS = VIH disables external address latching, causing the counter output to drive the memory array-ideal for sequential burst access patterns.

What package type is used for the 70V3569S5BC?

The 70V3569S5BC is supplied in a 208-pin Plastic Quad Flatpack (PQFP) package, with dimensions 28 mm × 28 mm × 3.5 mm and 0.65 mm lead pitch. Pinout and thermal/mechanical details are documented in the IDT datasheet section "Pin Configuration (DRG208)".

Is the 70V3569S5BC suitable for industrial temperature applications?

Yes, the 70V3569S5BC is explicitly rated for industrial temperature operation from –40°C to +85°C, as confirmed by the "70V3569S5" speed grade designation and the "Recommended Operating Temperature" table in the datasheet. It meets full AC/DC specifications across this range, including tCD2 ≤ 5 ns and ISB3 ≤ 30 mA.
