Product details
Overview
71V016SA20PHG8 from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V CMOS static RAM with 20 ns read/write cycle time, industrial temperature range (–40°C to +85°C), LVTTL-compatible I/O, and dual byte enable (BHE/BLE) for flexible data bus control in embedded memory subsystems.
For engineers reviewing the 71V016SA20PHG8 datasheet, 71V016SA20PHG8 pinout, 71V016SA20PHG8 application, or 71V016SA20PHG8 equivalent, key selection considerations include access timing consistency (tRC = tAA = 20 ns), low-power standby current (ISB = 30 mA max), 44-pin TSOP-II package compatibility, and byte-selectable 16-bit data interface for legacy bus architectures.
Technical Context
This device implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS technology optimized for deterministic timing across commercial and industrial temperature ranges. Its architecture supports simultaneous chip select (CS), output enable (OE), and byte enable (BHE/BLE) control for precise read/write granularity.
The 71V016SA20PHG8 features bidirectional LVTTL-compatible I/O buffers with guaranteed VOH ≥ 2.4 V (IOH = –4 mA) and VOL ≤ 0.4 V (IOL = 8 mA), and operates from a single 3.3 V supply (3.0–3.6 V). It supports three distinct write control modes: CS-, WE-, or byte-enable–controlled, 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 full 16-bit parallel data transfers without external multiplexing |
| Access/Cycle Time | 20 ns (tRC = tAA = tACS = 20 ns); ensures deterministic latency for real-time control and buffering applications |
| Supply Voltage | 3.0–3.6 V (typ. 3.3 V); compatible with standard LVTTL logic domains and eliminates need for level shifters |
| Operating Temperature | –40°C to +85°C; validated for industrial environments including motor drives and telecom infrastructure |
| Standby Current | ISB = 30 mA max (dynamic), ISB1 = 10 µA max (static); reduces power during idle cycles in battery-backed or energy-sensitive systems |
| I/O Interface | LVTTL-compatible bidirectional data (I/O0–I/O15); directly interfaces with FPGA I/O banks, microcontroller data buses, and ASIC glue logic |
| Enable Architecture | Dedicated CS, OE, BHE, BLE inputs; allows independent control of upper/lower bytes and output tri-state for shared bus arbitration |
Pinout & Package
71V016SA20PHG8 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 gull-wing leads suitable for reflow soldering in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus accepting 0–65,535; enables full 64K-word addressing without external decoding |
| CS | Chip Select | Active-low global enable; places device in active or high-impedance state based on decode logic |
| OE | Output Enable | Active-low control for output drivers; allows read data to appear on I/O pins only when asserted |
| WE | Write Enable | Active-low signal initiating write operation; latches data on rising edge of WE when CS and byte enables are active |
| BHE | High-Byte Enable | Active-low control for I/O8–I/O15; enables 8-bit writes to upper byte independently of lower byte |
| BLE | Low-Byte Enable | Active-low control for 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; functions as input during write, output during read, high-Z when disabled |
| VDD | Power Supply | +3.3 V supply pin; requires local 0.1 µF ceramic decoupling per VDD pin for noise immunity |
| VSS | Ground | Reference ground for all signals and internal logic; must be connected to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Equal access and cycle times | tRC = tAA = 20 ns ensures predictable worst-case latency for both reads and writes-critical for deterministic real-time firmware |
| Dual byte enable (BHE/BLE) | Enables independent 8-bit access to upper/lower data bytes, reducing bus contention and simplifying partial-word updates in 16-bit systems |
| Single 3.3 V supply | Eliminates need for dual-voltage rails or level translators, lowering BOM cost and layout complexity in LVTTL-based designs |
| Industrial temperature support | Validated operation from –40°C to +85°C confirms reliability in uncontrolled environments such as factory automation and outdoor base stations |
| Low dynamic standby current | ISB = 30 mA max at fMAX enables extended low-power hold states in battery-buffered SRAM applications |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-20ZSXI | Same 64K × 16 organization, 20 ns speed, but uses 48-pin TSOP-I and has higher ISB (45 mA max) | Requires PCB footprint change; better suited for designs already using Cypress's TSOP-I layout | Select if existing board uses 48-pin TSOP-I or if Cypress ecosystem toolchain support is required |
| AS6C1008-20TIN | 64K × 16, 20 ns, but rated only for commercial temp (0°C to +70°C); lower ICC (110 mA max vs. 120 mA) | Not qualified for industrial environments; unsuitable for extended-temperature deployments | Choose only for cost-sensitive commercial applications where ambient temperature remains tightly controlled |
Compared with CY62167EV30LL-20ZSXI and AS6C1008-20TIN, the 71V016SA20PHG8 offers verified industrial temperature operation in a widely adopted 44-pin TSOP-II package, making it the preferred choice for ruggedized embedded systems requiring long-term reliability without footprint redesign.

FAQ
What is the maximum operating frequency supported by the 71V016SA20PHG8?
The 71V016SA20PHG8 does not operate on a clock; it is an asynchronous SRAM. Its maximum effective bandwidth is determined by its 20 ns cycle time, enabling up to 50 MHz sustained random-access throughput (1 / 20 ns). Timing is governed by tRC, tAA, and tWC-not clock frequency-making it ideal for systems without synchronous memory controllers.
Does the 71V016SA20PHG8 require external refresh circuitry?
No. The 71V016SA20PHG8 is a fully static RAM and contains no capacitive storage cells. It retains data indefinitely as long as VDD is applied and does not require refresh cycles, clocks, or periodic access-unlike DRAM. This eliminates timing-critical refresh overhead in firmware and hardware design.
Can the 71V016SA20PHG8 be used with a 5 V microcontroller data bus?
No. The 71V016SA20PHG8 is strictly a 3.3 V LVTTL device: VIH minimum is 2.0 V and VOH is specified only down to 2.4 V at IOH = –4 mA. Direct connection to 5 V logic violates absolute maximum ratings and risks damage. A level-shifting interface is required for interoperability with 5 V systems.
What is the function of the BHE and BLE pins on the 71V016SA20PHG8?
BHE (High-Byte Enable) and BLE (Low-Byte Enable) are active-low 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 portion is written while the other remains unchanged-enabling efficient partial-word updates without read-modify-write sequences.
Is the 71V016SA20PHG8 RoHS-compliant and halogen-free?
Yes. Per Renesas' ordering information and datasheet revision history, the 71V016SA20PHG8 is a green part (marked with 'G' suffix) and conforms to RoHS Directive 2011/65/EU. It is also halogen-free and compliant with Renesas' "Restricted Hazardous Substance Device" specification, meeting IPC-4101D/93 requirements.
