Product details
Overview
70V09L15PFG from Integrated Device Technology is a high-speed 128K × 8 true dual-ported static RAM with independent left/right ports, 15 ns max access time (commercial grade), 3.3 V ±0.3 V single-supply operation, and integrated hardware semaphore/INT/BUSY arbitration logic - used in real-time interprocessor communication systems requiring concurrent memory access without software overhead.
For engineers reviewing the 70V09L15PFG datasheet, 70V09L15PFG pinout, 70V09L15PFG application, or 70V09L15PFG equivalent, key selection criteria include port-to-port contention resolution timing (tBDD ≤15 ns), semaphore flag update pulse width (tSOP = 10 ns), interrupt set/reset latency (tINS/tINR ≤20 ns), and TQFP-100 package compatibility for multi-processor bus architectures.
Technical Context
The 70V09L15PFG implements fully asynchronous dual-port architecture with separate address, data, and control buses per port (A0L–A16L/I/O0L–I/O7L/CE0L–CE1L/R/WL/OEL/SEML/INTL/BUSYL on left; mirrored on right), enabling simultaneous read/write to identical memory locations only when BUSY arbitration is disabled or resolved.
Its on-chip arbitration logic supports three coexistence mechanisms: (1) BUSY flag signaling (push-pull, non-tri-state) for hardware write inhibition during address contention, (2) eight dedicated semaphore latches (addressed by A0–A2) accessible via SEM=VIL mode, and (3) interrupt flags (INTL/INTR) triggered by writes to fixed mailbox addresses (1FFFEh/1FFFFh).

Pinout & Package
70V09L15PFG is housed in a 100-pin TQFP (PNG100) package with 0.5 mm pitch, 14 mm × 14 mm footprint, and exposed thermal pad (not electrically connected). Pin 1 is top-left corner (marked dot); pins numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A16L | Left port address inputs | 17-bit address bus for left-side memory access (A0L = LSB) |
| A0R–A16R | Right port address inputs | 17-bit address bus for right-side memory access (A0R = LSB) |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit data path; direction controlled by R/WL and OEL |
| I/O0R–I/O7R | Right port bidirectional data | 8-bit data path; direction controlled by R/WR and OER |
| CE0L, CE1L | Left port chip enables | Dual CE allows depth expansion without external logic; either enables port |
| CE0R, CE1R | Right port chip enables | Dual CE allows depth expansion without external logic; either enables port |
| R/WL, R/WR | Left/right read/write controls | Active-low; determines data direction when OE is active |
| OEL, OER | Left/right output enables | Active-low; tri-states I/O pins when deasserted |
| SEML, SEMR | Semaphore enable | Active-low; selects semaphore register bank (A0–A2) instead of RAM array |
| INTL, INTR | Interrupt flags | Open-drain compatible (but push-pull); asserted low on mailbox write |
| BUSYL, BUSYR | Busy flags | Push-pull outputs (master mode) or inputs (slave mode via M/S); indicate address contention |
| M/S | Master/slave select | VIL configures BUSY as input (slave); VIH configures BUSY as output (master) |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous read/write to same location only when BUSY arbitration is disabled - eliminates software polling loops |
| Hardware semaphore bank | Eight independent latches (A0–A2) with atomic read/write via SEM=VIL mode - prevents race conditions in resource locking |
| Configurable BUSY arbitration | Master mode (M/S=VIH) provides push-pull BUSY output for write gating; slave mode (M/S=VIL) accepts BUSY as write-inhibit input |
| Mailbox-style interrupts | INTL/INTR flags set/cleared by writes to fixed addresses (1FFFEh/1FFFFh) - enables zero-latency interprocessor signaling |
| Depth-expansion support | Dual CE0/CE1 per port allows cascading without external decode logic - simplifies >128K memory systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C028V-15AXC | 128K × 16 organization; 15 ns access; 3.3 V supply; 100-pin TQFP; no integrated semaphore logic | Requires external arbitration logic for interprocessor signaling; wider data bus suits 16-bit systems | Select when 16-bit data path is required and semaphore functionality is implemented in FPGA or software |
| IDT70V25L15PF | 32K × 16 organization; 15 ns access; 3.3 V supply; 100-pin TQFP; includes semaphore/interrupt but smaller memory size | Lower density limits use to compact control buffers; identical arbitration features simplify migration testing | Select when memory footprint constraints prioritize smaller capacity and pin-compatibility is critical |
Compared with CY7C028V-15AXC and IDT70V25L15PF, the 70V09L15PFG uniquely delivers 128K × 8 density with on-die semaphore and interrupt logic in a drop-in TQFP-100 package - reducing BOM count and PCB area versus discrete arbitration solutions.

FAQ
What is the maximum operating temperature range for the 70V09L15PFG?
The 70V09L15PFG is rated for commercial temperature range only: 0°C to +70°C. It is not qualified for industrial operation (–40°C to +85°C); that capability applies only to the 70V09L20 variant. Thermal derating is not supported - operation outside 0°C to +70°C may result in timing violations or data retention failure.
Does the 70V09L15PFG support true simultaneous read/write to the same memory location?
Yes, the 70V09L15PFG uses true dual-ported memory cells enabling simultaneous access to the same address - but only when BUSY arbitration is disabled (e.g., M/S = VIL on both sides) or when accesses are non-contenting (read/read). Simultaneous write/write triggers BUSY assertion and gates the later write, preserving data integrity.
How are the semaphore flags accessed on the 70V09L15PFG?
Semaphore flags are accessed by setting SEM = VIL and asserting CE = VIH (per Truth Table III), then using A0–A2 to select one of eight latches. I/O0 writes the flag value; I/O0–I/O7 simultaneously read the selected flag. This mode isolates semaphores from the main 128K × 8 memory array.
Can the 70V09L15PFG be used in a 5 V system?
No. The 70V09L15PFG requires a strict 3.3 V ±0.3 V supply (2.97 V to 3.63 V) and is not 5 V tolerant on any pin. Applying 5 V to VCC or I/O pins will cause permanent damage. Level-shifting circuitry is mandatory for interfacing with 5 V controllers.
What is the function of the M/S pin on the 70V09L15PFG?
The M/S pin configures BUSY pin behavior: VIH sets master mode (BUSYL/BUSYR become push-pull outputs for arbitration signaling); VIL sets slave mode (BUSYL/BUSYR become inputs that inhibit writes when driven low). This enables flexible master/slave array topologies without external logic.
