Renesas 7006S15PFI8

Overview

IDT7006S15PFI8 from Integrated Device Technology (IDT) is a high-speed 16K × 8 true dual-port static RAM with independent left/right ports, 15 ns maximum read cycle time (commercial grade), TTL-compatible 5V ±10% operation, and integrated on-chip semaphore and arbitration logic. It enables simultaneous asynchronous access to the same memory location and supports master/slave cascading for 16-bit+ data bus expansion in real-time inter-processor communication systems.

For engineers reviewing the IDT7006S15PFI8 datasheet, IDT7006S15PFI8 pinout, IDT7006S15PFI8 application, or IDT7006S15PFI8 equivalent, key selection considerations include its 15 ns access timing, dual-port arbitration behavior, BUSY/INT/SEM flag timing, industrial temperature support (–40°C to +85°C), and 64-pin TQFP package compatibility with PCB layout constraints for high-density embedded control designs.

Technical Context

The IDT7006S15PFI8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling concurrent read/write operations without external logic. Its on-chip arbitration resolves contention via BUSY flag assertion (output when M/S = H, input when M/S = L) and priority setup timing (tAPS = 5 ns).

It integrates full hardware semaphore signaling across ports using A0–A2 address lines to select one of eight flags, with dedicated SEM/SEML/SEMR pins and tSOP = 10 ns update pulse width. Data retention at 2V (L-version feature) is not applicable to this S-version part; power-down is controlled independently per port via CE.

FAQ

What is the maximum operating speed of the IDT7006S15PFI8?

The IDT7006S15PFI8 has a maximum read cycle time (tRC) of 15 ns, corresponding to a theoretical maximum throughput of approximately 66.7 MHz for consecutive reads. This timing is guaranteed across the full industrial temperature range (–40°C to +85°C) and 5.0 V ±10% supply, as specified in the AC Electrical Characteristics table for the 7006X15 speed grade.

Does the IDT7006S15PFI8 support battery backup for data retention?

No, the IDT7006S15PFI8 does not support battery backup data retention. That feature is exclusive to the "L" version (e.g., IDT7006L15PFI8), which specifies 2 V data retention current (ICCDR ≤ 4000 µA) and lower standby power. The "S" suffix denotes standard power operation with typical active current of 170 mA and ISB1 standby current of 20 mA.

How is arbitration handled between ports on the IDT7006S15PFI8?

Arbitration is managed entirely in hardware via the BUSY flag and M/S pin configuration. When M/S = H (master), BUSY is an output that asserts when both ports attempt simultaneous access to the same address. When M/S = L (slave), BUSY is an input used to stall the slave port's write cycle until the master releases the address. Priority setup time (tAPS = 5 ns) ensures deterministic resolution.

Can the IDT7006S15PFI8 be used in a 16-bit data bus configuration?

Yes, the IDT7006S15PFI8 supports 16-bit expansion via master/slave cascading. Two devices are connected with M/S = H on the master and M/S = L on the slave; BUSY outputs/inputs are linked, and address/data buses are aligned. This eliminates external logic and maintains full 15 ns speed across the combined 16-bit word, as documented in the functional description and pin configuration diagrams.

What package type is used for the IDT7006S15PFI8?

The IDT7006S15PFI8 uses a 64-pin Thin Quad Flatpack (TQFP) package, designated PNG64 in IDT documentation. Its dimensions are 14 mm × 14 mm × 1.4 mm with 0.5 mm lead pitch. This RoHS-compliant surface-mount package is optimized for high-density industrial PCB layouts and supports reflow soldering per JEDEC J-STD-020 standards.
