Product details
Overview
71V416YS10PHG from Integrated Device Technology is a 4-Mbit (256K × 16) high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and JEDEC-standard power/GND pinout for noise reduction. It supports byte-wide and word-wide read/write operations in commercial temperature range (0°C to +70°C) and is used in network packet buffers, FPGA configuration memory, and real-time control data storage.
For engineers reviewing the 71V416YS10PHG datasheet, 71V416YS10PHG pinout, 71V416YS10PHG application, or 71V416YS10PHG equivalent, key selection criteria include 10 ns read cycle time, SOJ-44 package compatibility, low-power standby current (70 mA), and dual-byte enable support for partial-word access in embedded systems.
Technical Context
The 71V416YS10PHG implements fully static asynchronous architecture-no clocks or refresh required-and uses dedicated OE, CS, WE, BHE, and BLE control inputs to manage output enable, chip select, write strobe, and high/low byte selection independently. Its bidirectional I/Os are LVTTL-compatible with VOH ≥ 2.4 V and VOL ≤ 0.4 V at specified loads.
Timing is defined by strict AC parameters including tAA = 10 ns (address access), tRC = 10 ns (read cycle), tWP = 8 ns (write pulse width), and tOHZ = 5 ns (output disable delay). Input and I/O capacitance are characterized at 7 pF and 8 pF respectively, supporting stable signal integrity on dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K × 16-bit (4,194,304 bits); enables 16-bit data bus interfacing without external multiplexing |
| Access Time (tAA) | 10 ns maximum; determines minimum latency between address assertion and valid data output |
| Supply Voltage | 3.0 V to 3.6 V; compatible with standard 3.3 V logic rails and tolerant of typical board-level ripple |
| Standby Current (ISB) | 70 mA max at VDD = max and f = fMAX; defines dynamic power draw during deselected operation |

Pinout & Package
71V416YS10PHG is housed in a 44-pin, 400-mil plastic SOJ package (SO44-1) with JEDEC-standard power/GND pinout for reduced switching noise. Pin 28 is NC or optionally connected to VSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; no internal latching |
| CS | Chip Select | Active-low enable for device selection; must be stable before address setup |
| OE | Output Enable | Active-low control for output drivers; allows shared bus operation with other devices |
| WE | Write Enable | Active-low strobe initiating write cycles; timing-critical for data setup/hold compliance |

| VSS | Ground | Signal ground reference; multiple VSS pins placed per JEDEC center-power/GND pattern |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC Center Power/GND Pinout | Reduces simultaneous switching noise (SSN) by interleaving VDD/VSS pins across the package body |
| Equal Access and Cycle Times | tAA = tRC = 10 ns ensures deterministic timing for both read and write cycles in real-time systems |
| Dual Byte Enable (BHE/BLE) | Enables independent 8-bit writes to upper or lower byte without read-modify-write overhead |
| Low-Power Standby Mode | ISB = 70 mA max under dynamic standby reduces system-level power when memory is idle but selected |
| Single 3.3 V Supply | Eliminates need for dual-voltage regulation, simplifying power delivery in compact embedded designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62148EV30LL-10ZSXI | 4-Mbit (256K × 16), 10 ns, 3.3 V, SOJ-44; higher ISB (100 mA) and no BHE/BLE pins | Lacks byte enable control; requires external logic for partial writes | Select when byte-select functionality is unnecessary and lower standby current is not critical |
| AS6C4008-10TIN | 4-Mbit (256K × 16), 10 ns, 3.3 V, TSOP-44; identical timing but different package footprint | TSOP-II instead of SOJ; requires PCB redesign for mounting and thermal management | Select only if TSOP-II is preferred for board space or thermal profile, and layout revision is feasible |
Compared with CY62148EV30LL-10ZSXI and AS6C4008-10TIN, the 71V416YS10PHG uniquely combines SOJ-44 packaging, JEDEC-compliant noise-reducing pinout, and hardware byte enable-making it optimal for space-constrained, noise-sensitive embedded systems requiring partial-word writes without added logic.

FAQ
What is the operating voltage range for the 71V416YS10PHG?
The 71V416YS10PHG operates over a supply voltage range of 3.0 V to 3.6 V, with nominal 3.3 V operation. This range accommodates typical board-level tolerances and ensures compatibility with standard 3.3 V logic families. The device is not rated for 5 V operation, and exceeding 3.6 V may cause permanent damage per absolute maximum ratings.
Does the 71V416YS10PHG require a clock or refresh signal?
No, the 71V416YS10PHG uses fully static asynchronous circuitry and requires no clock or refresh signals. Its operation depends solely on address, control (CS/OE/WE/BHE/BLE), and data timing-making it ideal for deterministic real-time systems where timing predictability is critical. This eliminates refresh overhead and associated jitter in time-sensitive applications.
What is the function of pins BHE and BLE on the 71V416YS10PHG?
BHE (High Byte Enable) and BLE (Low Byte Enable) are active-low inputs that independently control access to the upper (I/O8–I/O15) and lower (I/O0–I/O7) byte of the 16-bit data bus. When only one is asserted, the 71V416YS10PHG performs an 8-bit write without affecting the opposite byte-enabling efficient partial-word updates in microcontroller or FPGA systems.
Can the 71V416YS10PHG be used in industrial temperature environments?
No-the 71V416YS10PHG is specified only for the commercial temperature range (0°C to +70°C). For industrial operation (–40°C to +85°C), the pin-compatible 71V416YL10PHG variant must be used. The 'Y' suffix denotes commercial grade; 'L' indicates low-power industrial grade, and mixing grades risks timing violation or functional failure outside spec limits.
What package type does the 71V416YS10PHG use, and is it RoHS compliant?
The 71V416YS10PHG uses a 44-pin, 400-mil plastic SOJ (SO44-1) package. Per IDT documentation dated October 2003, this variant predates mandatory RoHS enforcement and is not RoHS-compliant. For RoHS-compliant alternatives, consult current Renesas equivalents or newer-generation SRAMs with explicit Pb-free markings and J-STD-609 classification.
