Product details
Overview
71V016SA12PHG from Renesas Electronics is a 64K × 16-bit (1 Mbit), 3.3 V high-speed CMOS static RAM with 12 ns access 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 71V016SA12PHG datasheet, 71V016SA12PHG pinout, 71V016SA12PHG application, or 71V016SA12PHG equivalent, this device supports fast asynchronous read/write cycles, low-power standby modes, and TSOP-44 packaging suitable for space-constrained industrial controllers, legacy bus interfaces, and FPGA co-processor buffers.
Technical Context
The 71V016SA12PHG implements fully static asynchronous circuitry-no clocks or refresh required-and uses high-reliability CMOS fabrication optimized for stable operation across voltage (3.15–3.6 V) and temperature extremes. Its architecture integrates independent address decoding, bidirectional LVTTL I/O buffers, and separate chip select (CS), output enable (OE), write enable (WE), and byte enable (BHE/BLE) controls.
Timing behavior is defined by equal access and cycle times (tAA = tRC = 12 ns max), with guaranteed low-latency transitions: tCLZ ≤ 4 ns, tOE ≤ 6 ns, and tWHZ ≤ 6 ns. The device supports three distinct write control modes-CS-, WE-, or byte-enable–triggered-with precise setup/hold timing validated under AC test loads per JEDEC standards.
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) | 12 ns max at VDD = 3.15–3.6 V, TA = –40°C to +85°C; determines minimum address-to-data-valid latency |
| Supply Voltage | 3.15–3.6 V; compatible with standard 3.3 V logic rails and tolerant of ±0.15 V variation |
| I/O Interface | LVTTL-compatible bidirectional I/O0–I/O15; interfaces directly with 3.3 V microcontrollers and FPGAs |
| Operating Temperature | –40°C to +85°C industrial grade; qualified for use in factory automation and outdoor edge devices |
| Package | 44-pin TSOP Type II (PHG44); JEDEC-standard footprint with 0.8 mm pitch, suitable for reflow assembly |
| Power Consumption | ISB ≤ 45 mA dynamic standby current; reduces system power during idle cycles without sacrificing wake-up speed |
Pinout & Package
71V016SA12PHG is housed in a 44-pin Plastic Thin Small Outline Package (TSOP Type II, PHG44), measuring 10.16 mm × 18.42 mm × 1.2 mm, with gull-wing leads and JEDEC MO-143AC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit row/column address bus; fully decoded internally to access all 64K locations |
| CS | Chip Select | Active-low global enable; places device in active or high-Z state based on control bus arbitration |
| OE | Output Enable | Active-low read strobe; enables output drivers independently of CS for shared-bus timing control |
| WE | Write Enable | Active-low write strobe; initiates write cycle when CS and BHE/BLE are asserted |
| BHE / BLE | Byte Enable | Independent high/low byte gating; allows 8-bit writes to upper or lower half of 16-bit word |
| I/O0–I/O15 | Bidirectional Data | 16-bit LVTTL I/O bus; direction controlled by WE and CS states per truth table |
| VDD / VSS | Power / Ground | Single 3.3 V supply pair; decoupling required within 10 mm of pins for noise immunity |
Key Features

|---|---|---|---|
| CY62167EV30LL-45ZSXI | 45 ns access time, 2 Mb density (128K × 16), 3.3 V core, SOIC-44 package | Lower speed but higher capacity; lacks byte enable pins and industrial temp support | Select only if system timing budget permits >3× slower access and board layout accommodates larger SOIC footprint |
| AS6C1008-12TIN | 12 ns access, 1 Mb (128K × 8), 3.3 V, TSOP-32 package | 8-bit bus width requires two devices for 16-bit interface; no BHE/BLE; commercial temp only (0°C to +70°C) | Use only in cost-sensitive consumer designs where 16-bit bus width is not required and ambient temperature stays below 70°C |

FAQ
What is the maximum operating frequency supported by the 71V016SA12PHG?
The 71V016SA12PHG does not operate on a clock signal-it is an asynchronous SRAM. Its performance is specified by access time (tAA ≤ 12 ns) and cycle time (tRC ≤ 12 ns), enabling reliable operation on bus systems up to approximately 83 MHz (1/12 ns). Timing depends on external controller setup/hold margins, not internal clocking.
Does the 71V016SA12PHG require refresh circuitry or periodic maintenance?
No, the 71V016SA12PHG is a fully static RAM and requires no refresh cycles, clocks, or periodic maintenance. Its CMOS latch-based memory cells retain data indefinitely as long as VDD remains within specification (3.15–3.6 V) and ambient temperature stays within –40°C to +85°C.
Can the 71V016SA12PHG be used with 5 V logic systems?
No-the 71V016SA12PHG is strictly a 3.3 V LVTTL device. Its inputs are not 5 V tolerant (VIH max = VDD + 0.3 V = 3.9 V), and VDD must remain between 3.15 V and 3.6 V. Interfacing with 5 V systems requires level-shifting circuitry on all address, control, and data lines.
What is the function of the BHE and BLE pins on the 71V016SA12PHG?
The BHE (High Byte Enable) and BLE (Low Byte Enable) pins on the 71V016SA12PHG independently gate the upper (I/O8–I/O15) and lower (I/O0–I/O7) bytes during write operations. When only one is active, the device performs an 8-bit write; when both are active, it executes a full 16-bit word write-enabling efficient partial-word updates without external byte masking logic.
Is the 71V016SA12PHG available in lead-free and RoHS-compliant packaging?
Yes-the 71V016SA12PHG is offered in green (halogen-free, RoHS-compliant) variants. Per Renesas ordering information, the "G" suffix in the package code (e.g., PHG) indicates compliance with JEDEC J-STD-020 and IEC 61249-2-21 standards, including lead-free solderability and restricted hazardous substance content.
