Product details
Overview
71V016SA10PHG from Renesas Electronics is a 64K × 16-bit, 1 Mbit high-speed CMOS static RAM with 10 ns access time, single 3.3 V supply operation, LVTTL-compatible I/O, and industrial-grade temperature range (–40°C to +85°C) support in PHG44 TSOP package. It serves as fast, asynchronous main or cache memory in embedded controllers, network interface cards, and real-time data buffering systems.
For engineers reviewing the 71V016SA10PHG datasheet, 71V016SA10PHG pinout, 71V016SA10PHG application, or 71V016SA10PHG equivalent, key selection criteria include its 10 ns read cycle time, byte-enable-controlled 16-bit bidirectional I/O, low-power standby current (45 mA max), and compatibility with legacy LVTTL bus architectures requiring no refresh or clocking.
Technical Context
The 71V016SA10PHG implements fully static asynchronous circuitry with no clocks or refresh required. Its architecture includes independent upper- and lower-byte enable (BHE/BLE), output enable (OE), chip select (CS), and write enable (WE) controls - enabling word, high-byte, or low-byte read/write operations without external logic.
All address (A0–A15), control (CS, OE, WE, BHE, BLE), and bidirectional data (I/O0–I/O15) signals are LVTTL-compatible with VIH = 2.0 V min and VIL = 0.8 V max at VDD = 3.3 V. The device supports three distinct timing modes: CS-controlled, OE-controlled, and byte-enable-controlled write cycles, each with defined setup/hold and pulse-width requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits); enables 16-bit parallel data transfers without external multiplexing |
| Access Time (tAA) | 10 ns max; determines minimum latency between address assertion and valid data on I/O bus |
| Read Cycle Time (tRC) | 10 ns max; defines shortest interval between successive read operations |
| Supply Voltage | 3.15–3.6 V; single 3.3 V rail simplifies power design and ensures LVTTL signal compatibility |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including motor drives and base station equipment |
| Standby Current (ISB) | 45 mA max; low dynamic standby power enables energy-efficient idle states in battery-backed systems |
| I/O Interface | LVTTL-compatible; directly interfaces with 3.3 V microcontrollers, FPGAs, and ASICs without level shifters |
Pinout & Package
71V016SA10PHG is packaged in a JEDEC-standard 44-pin TSOP Type II (PHG44) with 0.8 mm pitch, 12.0 × 20.0 mm body size, and surface-mount footprint optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; no internal latching required |
| CS | Chip Select | Active-low global enable; places device in active or high-Z standby mode depending on logic level |
| OE | Output Enable | Active-low control for output drivers; enables read data only when CS and OE are both low |
| WE | Write Enable | Active-low signal initiating write cycle; combined with CS and BHE/BLE determines write granularity |
| BHE / BLE | Byte Enable Inputs | Independent high- and low-byte controls; allow 8-bit writes to upper or lower half of 16-bit word |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit LVTTL I/O; tristated during reads/writes based on OE, CS, and WE state transitions |
| VDD | Power Supply | +3.3 V supply input; decoupling capacitor placement near pins critical for noise immunity |
| VSS | Ground | Signal and power ground reference; multiple VSS pins reduce ground bounce in high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clocks or refresh cycles needed; eliminates timing constraints from system clock domain |
| Byte-Selectable Write | BHE/BLE pins enable independent 8-bit writes to upper or lower byte - reduces bus contention and improves efficiency |
| Low-Power Standby Mode | ISB = 45 mA max at 10 ns speed grade; cuts power by >70% vs. active operation while preserving data |
| LVTTL Signal Compatibility | Direct interface with 3.3 V logic families; eliminates need for level-shifting components on data/address/control lines |

|---|---|---|---|
| CY62167EV30LL-10ZSXI | 512K × 16-bit (8 Mbit), 10 ns access, 3.3 V, SOIC-44; higher density but larger package footprint | Requires PCB layout change due to SOIC-44 vs. TSOP-44; not drop-in compatible | Select when >1 Mbit capacity is required and board space permits SOIC mounting |
| IS61LV25616AL-10TLI | 256K × 16-bit (4 Mbit), 10 ns, 3.3 V, TSOP-44; same package but double density and higher ICC (180 mA) | Higher power draw limits use in thermally constrained designs; identical pinout enables direct replacement if power budget allows | Choose for capacity upgrade where thermal margin exists and PHG44 footprint must be retained |

FAQ
What is the maximum operating frequency supported by the 71V016SA10PHG?
The 71V016SA10PHG does not operate on a clock signal - it is an asynchronous SRAM. Its performance is specified by timing parameters: 10 ns access time (tAA), 10 ns read cycle time (tRC), and 10 ns write cycle time (tWC). These define the fastest achievable random read/write rates under worst-case conditions, not a clock frequency.
Does the 71V016SA10PHG require external refresh circuitry?
No. The 71V016SA10PHG is a fully static RAM using CMOS latch-based memory cells. It retains data indefinitely as long as VDD is applied and requires no refresh cycles, clocks, or external timing control - unlike DRAM devices.
Can the 71V016SA10PHG be used with 5 V logic systems?
No. The 71V016SA10PHG is strictly a 3.3 V device with LVTTL-compatible I/O (VIH min = 2.0 V, VIL max = 0.8 V). Interfacing with 5 V logic requires level-shifting circuitry; direct connection may damage the device or cause unreliable operation.
What is the meaning of "PHG" in the part number 71V016SA10PHG?
"PHG" denotes the package type: 44-pin TSOP Type II (PHG44), standardized per JEDEC MO-141. This surface-mount package features gull-wing leads, 0.8 mm pitch, and a 12.0 × 20.0 mm body - optimized for automated assembly and high-density routing.
Is the 71V016SA10PHG RoHS-compliant and halogen-free?
Yes. Per Renesas ordering information, the "G" suffix in 71V016SA10PHG indicates Green (lead-free, RoHS-compliant, and halogen-free) construction. It meets JEDEC JS709B and IPC-1752A material declaration requirements.
