Product details
Overview
IDT7007S20PF8 from IDT (Integrated Device Technology) is a high-speed 32K × 8 dual-port static RAM with true independent left/right ports, 20 ns maximum access time (industrial grade), 5 V ±10% single-supply operation, and on-chip semaphore/interrupt arbitration logic - used in real-time inter-processor communication systems such as industrial PLCs and avionics data concentrators.
For engineers reviewing the IDT7007S20PF8 datasheet, IDT7007S20PF8 pinout, IDT7007S20PF8 application, or IDT7007S20PF8 equivalent, key selection considerations include BUSY-flag arbitration timing (tBDD ≤ 30 ns), semaphore address decoding (A0–A2), master/slave M/S pin configuration, and 80-pin TQFP package compatibility with high-density PCB layouts.
Technical Context
The IDT7007S20PF8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port - enabling simultaneous read/write to the same memory location without contention when BUSY arbitration is disabled. Its on-chip hardware semaphore logic supports eight shared flags accessed via A0–A2 with CE = VIH/SEM = VIL mode.
It features push-pull BUSY and INT outputs (not tri-state), TTL-compatible signaling, and automatic power-down per port via independent chip enables (CEL/CER). The M/S pin configures port behavior: HIGH enables BUSY output (Master), LOW enables BUSY input (Slave), directly controlling write inhibition during arbitration.

Pinout & Package
Package: 80-pin thin quad flatpack (TQFP), code PNG80, body size 14 mm × 14 mm × 1.4 mm. All VCC pins require local decoupling; all GND pins must be connected to system ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A14L | Left port address inputs | 15-bit address bus for left-side memory access; latched on CE/R/W edge |

| CEL / CER | Chip enable (left/right) | Active-low per-port power gating; drives port into standby (ISB1/ISB2) when high |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; determines data flow direction when OE is active |
| OEL / OER | Output enable (left/right) | Tri-states I/O drivers when high; required for read operations |
| SEML / SEMR | Semaphore enable (left/right) | Activates semaphore register access (A0–A2) when low; CE must be high |
| INTL / INTR | Interrupt flag (left/right) | Push-pull outputs asserted on mailbox writes (7FFE/7FFF); cleared by read |
| BUSYL / BUSYR | Busy flag (left/right) | Push-pull outputs (Master) or inputs (Slave); blocks writes during arbitration |
| M/S | Master/Slave select | Configures BUSY behavior: HIGH = BUSY output (Master), LOW = BUSY input (Slave) |
| VCC / GND | Power & ground | Multiple distributed VCC/GND pins ensure low-impedance supply routing and noise immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress CY7C028V-20AC | 20 ns access, 32K × 8, but uses 100-pin TQFP; no integrated semaphore logic | Requires external arbitration logic for semaphore use; higher pin count increases layout area | Select when legacy Cypress toolchain support is required and external arbitration is acceptable |
| Renesas R1EX24032AS0C-20#U0 | 20 ns access, 32K × 8, 80-pin TQFP, but only commercial temp range (0°C to +70°C) | Not qualified for industrial environments; lacks BUSY arbitration timing guarantees at −40°C | Select only for cost-sensitive commercial systems where extended temperature operation is unnecessary |
Compared with CY7C028V-20AC and R1EX24032AS0C-20#U0, the IDT7007S20PF8 uniquely integrates hardware semaphore and BUSY arbitration in an industrial-grade 80-pin package - reducing BOM count and ensuring deterministic timing across −40°C to +85°C.

FAQ
What is the operating temperature range for the IDT7007S20PF8?
The IDT7007S20PF8 is rated for industrial temperature operation from −40°C to +85°C. This is confirmed in the Absolute Maximum Ratings and DC Electrical Characteristics tables, where "7007S" suffix denotes industrial-grade speed and temperature qualification. The 20 ns access time is guaranteed across this full range.
Does the IDT7007S20PF8 support true simultaneous read/write to the same memory address?
Yes, the IDT7007S20PF8 supports true simultaneous reads of the same memory location from both ports. Writes to identical addresses are resolved via hardware BUSY arbitration - if enabled - or proceed concurrently only when BUSY logic is disabled and M/S is configured appropriately. This behavior is explicitly stated in the Features section and Truth Table I.
How is semaphore functionality implemented in the IDT7007S20PF8?
Semaphore functionality in the IDT7007S20PF8 uses eight dedicated flags addressed by A0–A2. Access requires CE = VIH and SEM = VIL (per Truth Table II). Writing to I/O0 sets the flag; reading returns the state on all I/O lines. This is fully hardware-implemented with no firmware dependency - confirmed in Functional Block Diagram and Truth Table V.
What package type does the IDT7007S20PF8 use, and is it RoHS-compliant?
The IDT7007S20PF8 uses an 80-pin thin quad flatpack (TQFP) package, designated PNG80, with dimensions 14 mm × 14 mm × 1.4 mm. Per the "Green parts available" note and ordering information in the datasheet, this variant is RoHS-compliant and lead-free - verified in the official IDT documentation and distributor listings.
Can the IDT7007S20PF8 be used in a Master/Slave configuration for 16-bit data bus expansion?
Yes, the IDT7007S20PF8 supports Master/Slave cascading via the M/S pin. When configured as Master (M/S = H), BUSY is an output; as Slave (M/S = L), BUSY is an input that inhibits writes. This enables seamless 16-bit-or-wider memory systems without external logic - explicitly documented in the Features and Description sections.
