Product details
Overview
70V3399S133BF from Integrated Device Technology is a high-speed 256K × 18-bit synchronous dual-port SRAM with true dual-port architecture enabling simultaneous read/write access to the same memory location from independent left and right ports. It operates at 133MHz (7.5ns cycle time), supports selectable 3.3V or 2.5V I/O interfaces per port, and delivers 4.2ns clock-to-data-out in pipelined mode - ideal for real-time packet buffering in telecom line cards and FPGA co-processor data exchange.
For engineers reviewing the 70V3399S133BF datasheet, 70V3399S133BF pinout, 70V3399S133BF application, or 70V3399S133BF equivalent, key selection criteria include its 128-pin TQFP package with pipelined-only output mode, industrial temperature support (–40°C to +85°C), dual chip enable for depth expansion, and JTAG-compatibility exclusion due to pin count constraints.
Technical Context
This device implements full synchronous operation on both ports with registered address, data, and control inputs - enabling minimal 1.7ns setup and 0.5ns hold times at 133MHz. Its self-timed write architecture maintains fast cycle time without external wait-state logic.
The memory array uses true dual-port cells with separate byte enables (UBL/LBL and UBR/LBR) and dual-cycle deselect (DCD) for pipelined outputs. Counter enable (CNTENL/CNTENR) and repeat (REPEATL/REPEATR) features support burst-addressing modes without external address generators.

Pinout & Package
70V3399S133BF is housed in a 128-pin Thin Quad Flatpack (TQFP) with 0.5mm pitch, body size 14mm × 20mm × 1.4mm. All VDD pins require 3.3V supply; VDDQL/VDDQR must match OPTL/OPTR voltage selection (3.3V or 2.5V). A17L and A17R are no-connects.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKL / CLKR | Port-synchronous clock input | Registers all address, data, and control signals on rising edge; determines timing boundaries for both ports |
| CE0L/CE1L, CE0R/CE1R | Dual chip enables per port | Enable depth expansion without external logic; CE0X = VIL & CE1X = VIH activates port X |
| R/WL / R/WR | Read/write direction control | Synchronous signal sampled on CLK edge; controls data flow direction for each port independently |
| OEL / OER | Asynchronous output enable | Directly gates output drivers; high-Z state enabled regardless of clock or CE state |
| UBL/LBL, UBR/LBR | Byte enable controls | Independently mask upper (I/O9–I/O17) or lower (I/O0–I/O8) 9-bit bytes during read/write |
| A0L–A16L, A0R–A16R | Address inputs | 17-bit address bus per port; A17L/A17R are NC per datasheet note |
| I/O0L–I/O17L, I/O0R–I/O17R | Bidirectional data bus | 18-bit multiplexed data path per port; compatible with LVTTL signaling at selected VDDQ |
| OPTL / OPTR | I/O voltage select | Set to VIH (3.3V) or VIL (0V) to configure corresponding port's I/O voltage level and required VDDQ supply |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables concurrent read/write to identical addresses across ports - essential for inter-processor communication without arbitration overhead |
| Self-timed write architecture | Eliminates need for external write-strobe timing control; guarantees minimum cycle time compliance under all process/voltage/temperature corners |
| Dual-cycle deselect (DCD) | Prevents bus contention during rapid port switching by enforcing two-cycle deactivation of outputs in pipelined mode |
| Separate per-port I/O voltage control | Allows left port to interface with 3.3V FPGA while right port connects to 2.5V ASIC - no level-shifter required |
| Counter enable and repeat functions | Reduces address bus width and controller complexity in sequential-access applications like FIFO emulation or DMA buffer management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1362BV33-133BZI | 133MHz, 256K×18, 128-pin TQFP; supports flow-through mode; no counter/repeat features | Lacks address counter and repeat functionality; requires external logic for burst addressing | Choose when pipelined latency is not required and simpler control logic is preferred |
| AS7C3256B-133JCIN | 133MHz, 256K×18, 128-pin TQFP; single 3.3V I/O supply only; no OPT pin flexibility | Fixed 3.3V I/O interface; incompatible with mixed-voltage systems requiring 2.5V port interfacing | Choose for cost-sensitive designs where both ports operate at 3.3V and JTAG is unnecessary |
Compared with CY7C1362BV33-133BZI and AS7C3256B-133JCIN, the 70V3399S133BF uniquely combines industrial temperature rating, per-port I/O voltage selection, and integrated address counter - reducing BOM count and PCB area in mixed-signal embedded systems.

FAQ
What is the maximum guaranteed operating frequency of the 70V3399S133BF?
The 70V3399S133BF is rated for guaranteed operation up to 133MHz across the industrial temperature range (–40°C to +85°C), with a 7.5ns clock cycle time and 4.2ns clock-to-data-out delay in pipelined mode. This specification is validated per datasheet Table 11 and applies to both ports simultaneously under worst-case voltage and temperature conditions.
Does the 70V3399S133BF support flow-through output mode?
No, the 70V3399S133BF does not support flow-through output mode. As explicitly stated in the datasheet (Note 8, Pin Configuration section), the 128-pin TQFP package lacks sufficient pins to implement the PIPE/FT selection function - the device operates exclusively in pipelined output mode on both left and right ports.
Can the left and right ports of the 70V3399S133BF operate at different I/O voltages?
Yes, the 70V3399S133BF supports independent I/O voltage selection per port: OPTL configures the left port's VDDQL supply (3.3V or 2.5V), and OPTR configures the right port's VDDQR supply. This allows one port to interface with a 3.3V FPGA while the other connects to a 2.5V ASIC without external level shifters.
Is JTAG boundary scan supported on the 70V3399S133BF?
No, JTAG is not supported on the 70V3399S133BF. Due to the pin-count limitation of the 128-pin TQFP package, the TDI, TDO, TCK, TMS, and TRST pins required for IEEE 1149.1 compliance are omitted - this is confirmed in multiple datasheet notes (Pin Configuration pages 2–4, Note 9).
What is the purpose of the CNTEN and REPEAT pins on the 70V3399S133BF?
The CNTENL/CNTENR and REPEATL/REPEATR pins enable autonomous address generation: when CNTENX is asserted, the internal counter advances on each CLKX edge; REPEATX resets the counter to the last valid address loaded via ADSX. This eliminates the need for external address sequencers in applications like DMA buffers or FIFO emulation.
