Product details
Overview
71016S12PHG from Renesas Electronics is a 64K × 16-bit (1,048,576-bit), high-speed CMOS static RAM with 12 ns access time, TTL-compatible I/O, single 5V supply operation, and byte-enable control for embedded memory subsystems in industrial controllers and legacy computing systems.
For engineers reviewing the 71016S12PHG datasheet, 71016S12PHG pinout, 71016S12PHG application, or 71016S12PHG equivalent, this device supports fast asynchronous read/write cycles, low-power standby modes, and JEDEC-standard 44-pin TSOP packaging - critical for memory upgrades, FPGA configuration buffers, and real-time data logging designs.
Technical Context
The 71016S12PHG implements fully static asynchronous circuitry-no clocks or refresh required-and uses dual byte enable (BHE/BLE) to support 8-bit sub-word accesses within its 16-bit data bus. Its output enable (OE) enables 7 ns output valid timing independent of chip select.
It features three distinct standby power states: TTL-level ISB (60 mA max), CMOS-level ISB1 (10 µA), and dynamic ICC (210 mA max at fMAX), enabling precise power budgeting across active, partial, and deep-sleep modes in resource-constrained systems.

Use Value: Enables deterministic 1 ms PLC scan cycles using byte-enables to update only changed registers-reducing bus traffic and power vs. full-word writes. | Use Scenario: Replacing aging SRAM in ISA-bus-based test equipment and retro-computing platforms requiring 5V TTL compatibility. IC Role / Device Role / Timing Role: Drop-in replacement for obsolete 6264/62256-style memories; matches pinout and timing of original 44-pin SOJ packages when adapted to TSOP footprint. Use Value: Restores system functionality without redesign-leverages existing 5V bus, OE-controlled tristate, and 12 ns tAA to meet vintage CPU timing budgets. |
| FPGA Configuration Storage | Real-Time Data Logger Buffer |
Use Scenario: Holding boot-time configuration bitstreams for Xilinx Spartan-3 or Altera Cyclone II FPGAs in field-deployed instrumentation. IC Role / Device Role / Timing Role: Parallel-programmable configuration memory mapped to FPGA's INIT/PROGRAM pins; accessed via dedicated 16-bit bus during power-up. Use Value: Eliminates serial PROM bottlenecks-12 ns tAA cuts configuration time by >40% vs. 25 ns alternatives, accelerating system boot and reconfiguration. | Use Scenario: Capturing high-speed sensor samples (e.g., vibration, temperature) in automotive diagnostic tools with burst acquisition up to 1 MS/s. IC Role / Device Role / Timing Role: High-bandwidth circular buffer interfaced to ADC controller; uses BHE/BLE to alternate between upper/lower bytes during DMA bursts. Use Value: Sustains 16-bit data throughput at 83 MB/s (tRC = 12 ns) without FIFO overflow-critical for uninterrupted capture of transient events. |
Equivalent & Alternatives

FAQ
What is the operating temperature range for the 71016S12PHG?
The 71016S12PHG is rated for commercial temperature operation from 0°C to +70°C. It is not qualified for industrial temperature range (–40°C to +85°C) at the 12 ns speed grade-only 15 ns and 20 ns variants support industrial grading per Renesas ordering information.
Does the 71016S12PHG require an external clock or refresh circuitry?
No, the 71016S12PHG uses fully static CMOS circuitry and requires no clock input or periodic refresh cycles. This eliminates timing constraints associated with DRAM or pseudo-static RAM, simplifying system design and improving reliability in deterministic real-time applications.
Can the 71016S12PHG be used with a 3.3V microcontroller interface?
The 71016S12PHG is strictly a 5V device with TTL-compatible I/O thresholds (VIH = 2.2 V min, VIL = 0.8 V max). Direct connection to 3.3V logic risks violating input high-voltage limits and may cause unreliable operation; level-shifting circuitry is required for safe interfacing.
What package type does the 71016S12PHG use, and is it RoHS compliant?
The 71016S12PHG uses a 44-pin TSOP Type II package (PHG44) and is marked "Green" in Renesas documentation, confirming compliance with RoHS Directive 2011/65/EU and absence of restricted hazardous substances including lead, cadmium, and hexavalent chromium.
How does byte enable functionality work on the 71016S12PHG?
The 71016S12PHG uses separate BHE (high byte enable) and BLE (low byte enable) inputs to gate writes to I/O8–I/O15 and I/O0–I/O7 respectively. When only one is asserted low during a write cycle, only that 8-bit portion is updated-preserving the other byte's contents without requiring read-modify-write sequences.
