Renesas 7006S17PF

Overview

7006S17PF from IDT is a high-speed 16K × 8 true dual-port static RAM with independent left/right ports, 17 ns maximum access time (commercial grade), TTL-compatible 5 V ±10% supply, and on-chip semaphore/arbitration logic for inter-port synchronization in real-time embedded systems.

For engineers reviewing the 7006S17PF datasheet, 7006S17PF pinout, 7006S17PF application, or 7006S17PF equivalent, this device supports simultaneous asynchronous reads/writes across ports, battery-backed data retention down to 2 V, and master/slave cascading for 16-bit+ bus expansion without external logic.

Technical Context

The 7006S17PF implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling concurrent access to any memory location. Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports semaphore signaling using A0–A2 address lines to select among eight flags.

It features two distinct operational modes: RAM access (CE = LOW, SEM = HIGH) and semaphore access (CE = HIGH, SEM = LOW), with dedicated timing parameters for each-e.g., tSAA ≤ 17 ns for semaphore address access and tSWRD = 5 ns for semaphore write-to-read delay.

Key Specifications

Pinout & Package

7006S17PF is packaged in a 64-pin thin quad flatpack (TQFP), measuring 14 mm × 14 mm × 1.4 mm, with 0.5 mm lead pitch and exposed thermal pad. All VCC and GND pins must be connected per datasheet note.

FAQ

What is the maximum operating speed of the 7006S17PF?

The 7006S17PF has a maximum access time of 17 ns under commercial conditions (0°C to +70°C, VCC = 4.5 V to 5.5 V), corresponding to a minimum read cycle time (tRC) of 17 ns. This enables reliable operation at up to ~58.8 MHz sustained dual-port throughput when both ports are active.

Does the 7006S17PF support battery backup operation?

Yes, the 7006S17PF supports data retention at VCC = 2.0 V minimum, allowing it to maintain valid memory contents during main power loss. This feature is inherent to the "L" variant design, and the 7006S17PF-though an "S"-suffix part-shares the same 2 V retention specification per IDT documentation.

How does the M/S pin affect BUSY signal behavior on the 7006S17PF?

When M/S = HIGH, the 7006S17PF operates as a master: BUSYL is an output that asserts during port contention, and BUSYR is an output reflecting right-port arbitration status. When M/S = LOW, it acts as a slave: BUSYL becomes an input (used to receive BUSY from a master), and BUSYR remains an output.

Can the 7006S17PF be used in a 16-bit data bus configuration?

Yes-the 7006S17PF supports 16-bit expansion via its Master/Slave select (M/S) feature. Two devices can be cascaded: one configured as master (M/S = HIGH), the other as slave (M/S = LOW), enabling full-speed 16-bit word access without external logic or timing penalties.

What are the key timing differences between RAM access and semaphore access on the 7006S17PF?

RAM access requires CE = LOW and SEM = HIGH, with tAA ≤ 17 ns. Semaphore access requires CE = HIGH and SEM = LOW, with tSAA ≤ 17 ns and tSOP = 10 ns. The 7006S17PF guarantees identical access timing for both modes, simplifying timing budgeting in systems using both functions.
