Product details
Overview
71V016SA15PHGI from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V high-speed CMOS static RAM with 15 ns access time, industrial temperature range (–40°C to +85°C), LVTTL-compatible I/O, and byte-enable control. It operates asynchronously without clocks or refresh, supports word/byte read-write operations, and is used in real-time embedded controllers, network packet buffers, and FPGA configuration memory.
For engineers reviewing the 71V016SA15PHGI datasheet, 71V016SA15PHGI pinout, 71V016SA15PHGI application, or 71V016SA15PHGI equivalent, key selection criteria include its 15 ns tAA timing, industrial-grade reliability, TSOP-44 package compatibility, and dual-byte enable architecture for efficient 8-bit subsystem interfacing.
Technical Context
The 71V016SA15PHGI implements fully static asynchronous logic with no clock or refresh required. Its address decoding, sense amplifiers, and bidirectional I/O drivers are all fabricated in high-reliability CMOS, enabling stable operation across –40°C to +85°C at 3.3 V ±0.15 V.
It supports three independent write-enable modes-chip-select-controlled, output-enable-controlled, and byte-enable-controlled-with guaranteed tWP = 10 ns and tDW = 7 ns. The device uses separate BHE/ BLE inputs to gate high- and low-byte data paths, allowing partial writes without disturbing adjacent bytes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits); enables 16-bit data bus interfacing without external multiplexing |
| Access Time (tAA) | 15 ns max; determines minimum address-to-data valid delay in read cycles |
| Supply Voltage | 3.15 V to 3.6 V; compatible with standard 3.3 V LVTTL logic rails and noise margins |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including motor drives and base station control |
| I/O Interface | LVTTL-compatible bidirectional data (I/O0–I/O15); interfaces directly with FPGA I/O banks and microcontroller data buses |
| Power Consumption | ISB1 = 10 µA typical full standby current; enables ultra-low-power hold mode during system sleep |
| Byte Enable Control | Dedicated BHE and BLE pins; permits independent 8-bit writes to upper/lower byte lanes without read-modify-write overhead |
Pinout & Package
71V016SA15PHGI is packaged in a JEDEC-standard 44-pin TSOP Type II (PHG44) with 0.8 mm pitch, 12.0 × 20.0 mm footprint, and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; latched on CS transition |
| CS | Chip Select | Active-low enable; device enters active mode only when CS = L; enables multi-chip memory expansion |
| OE | Output Enable | Active-low; controls output drivers independently of CS/WE; allows data bus sharing |
| WE | Write Enable | Active-low; initiates write cycle when CS and BHE/ BLE are also low; defines write vs. read mode |
| BHE | High-Byte Enable | Active-low; gates I/O8–I/O15; enables 8-bit writes to upper byte without affecting lower byte |
| BLE | Low-Byte Enable | Active-low; gates I/O0–I/O7; enables 8-bit writes to lower byte without affecting upper byte |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; direction controlled by WE state; high-impedance when CS/OE/BHE/ BLE inactive |
| VDD | Power Supply | +3.3 V supply; must be decoupled locally with 0.1 µF ceramic capacitor per VDD pin |
| VSS | Ground | Signal and power ground reference; requires low-inductance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clocks or refresh required; simplifies timing design and eliminates refresh overhead in real-time systems |
| Byte-Selectable Write Architecture | Independent BHE/ BLE control enables true 8-bit sub-word writes - critical for protocol stack buffers and register-mapped peripherals |
| Industrial Temperature Support | Guaranteed 15 ns performance over –40°C to +85°C; validated for use in automotive ECUs and industrial PLCs |
| LVTTL-Compatible I/O | Direct interface with 3.3 V microcontrollers, FPGAs, and ASICs without level-shifting circuitry |
| Low Standby Power | ISB1 = 10 µA max; reduces system power budget during idle states in battery-backed or energy-conscious designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXI | 45 ns access time; 512K × 16 organization; 3.3 V core but 2.5 V I/O tolerant; 48-TSOP II package | Lower speed but larger density; suited for non-real-time firmware storage rather than latency-critical buffers | Select when >1 Mbit capacity is needed and 45 ns latency is acceptable; verify I/O voltage compatibility with host controller |
| AS6C1008-15TIN | 15 ns access; 128K × 8 organization; 3.3 V only; 32-pin SOJ package; no byte enable pins | 8-bit bus width limits throughput; lacks BHE/ BLE - requires external logic for byte masking | Choose for cost-sensitive 8-bit microcontroller systems where 16-bit parallelism and byte masking are unnecessary |
Compared with 71V016SA15PHGI, CY62167EV30LL-45ZSXI trades speed for density and adds I/O voltage flexibility, while AS6C1008-15TIN reduces pin count and cost at the expense of bus width and byte-select capability - making 71V016SA15PHGI optimal for 16-bit, low-latency, industrial-grade memory subsystems.

FAQ
What is the maximum operating frequency supported by the 71V016SA15PHGI?
The 71V016SA15PHGI does not operate on a clock signal - it is an asynchronous static RAM. Its maximum effective throughput is determined by its 15 ns read/write cycle time (tRC), enabling up to 66.7 MHz sustained random-access bandwidth on a 16-bit bus. Timing is governed by address setup/hold and control signal propagation, not a system clock.
Does the 71V016SA15PHGI require external refresh circuitry?
No, the 71V016SA15PHGI is a fully static RAM and requires no refresh cycles or external refresh circuitry. Its CMOS latch-based memory cells retain data indefinitely as long as VDD is applied and operating specifications are met - a key advantage over DRAM in deterministic real-time systems.
Can the 71V016SA15PHGI be used with a 5 V microcontroller interface?
No - the 71V016SA15PHGI is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH minimum is 2.0 V. Direct connection to 5 V logic violates voltage ratings and risks damage. Level translation (e.g., TXB0108) is mandatory for 5 V host interfaces.
What is the function of the BHE and BLE pins on the 71V016SA15PHGI?
BHE (High-Byte Enable) and BLE (Low-Byte Enable) are active-low control inputs that independently gate the upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes during write operations. When only one is asserted, the corresponding 8-bit lane is written while the other remains unchanged - enabling efficient byte-level updates without read-modify-write sequences.
Is the 71V016SA15PHGI RoHS-compliant and halogen-free?
Yes - the 71V016SA15PHGI is a green-part designation ('G' suffix in ordering code), meaning it complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. This is confirmed in the Renesas datasheet Section 8 ("Ordering Information") and applies to all PHGI and BFGI variants.
