Product details
Overview
71016S12PHG8 from Renesas Electronics is a 64K × 16-bit (1 Mbit) 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 71016S12PHG8 datasheet, 71016S12PHG8 pinout, 71016S12PHG8 application, or 71016S12PHG8 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 interfaces.
Technical Context
The 71016S12PHG8 implements fully static asynchronous circuitry with no clocks or refresh required. It uses dual byte enable (BHE/BLE) to support 8-bit sub-word access and features separate chip select (CS) and output enable (OE) pins for precise bus timing control.
Its architecture includes TTL-compatible bidirectional I/O buffers, address latching via A0–A15 inputs, and independent write enable (WE) logic that enables word, high-byte, or low-byte writes per the truth table. Standby current drops to 10 µA under CMOS-level chip deselect.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-45ZSXIT | 45 ns access time, 3.3V supply, 512K × 16 organization | Requires voltage translation and layout revision; suited for lower-speed, low-voltage modern designs | Select only if migrating to 3.3V systems and accepting longer access latency |
| AS6C1008-12ZIN | 12 ns access, 5V supply, but 128K × 8 organization (not 64K × 16) | Needs bus-width adaptation (two devices or multiplexing); different pinout and byte-enable logic | Consider only when 8-bit data path is acceptable and PCB redesign is feasible |
Compared with CY62167EV30LL-45ZSXIT and AS6C1008-12ZIN, the 71016S12PHG8 delivers true 16-bit-wide, 5V, 12 ns performance in a drop-in PHG44 package - preserving timing margins and eliminating level-shifting or bus-width conversion in legacy 5V designs.

FAQ
What is the operating temperature range for the 71016S12PHG8?
The 71016S12PHG8 is specified for commercial temperature operation from 0°C to +70°C. This grade is confirmed in the Ordering Information table and AC Electrical Characteristics section of the Renesas datasheet, where 12 ns speed is explicitly marked "Commercial only." Industrial-grade variants (e.g., 71016S12PHGI8) exist but use different part numbers.
Does the 71016S12PHG8 require a refresh clock or external timing signals?
No, the 71016S12PHG8 uses fully static asynchronous circuitry and requires no clocks, refresh cycles, or external timing signals. Its operation relies solely on address, control (CS/OE/WE/BHE/BLE), and data transitions - a key feature confirmed in the Description section stating "fully static asynchronous circuitry is used, requiring no clocks or refresh for operation."
What package type and dimensions does the 71016S12PHG8 use?
The 71016S12PHG8 uses a 44-pin Thin Small Outline Package (TSOP Type II) with package code PHG44. Per the Pin Configurations diagram and Ordering Information, it measures 10.16 mm × 18.42 mm with 0.8 mm lead pitch and gull-wing leads - a JEDEC-standard footprint identical to other 71016 family members in TSOP.
Can the 71016S12PHG8 be used with a 3.3V system?
No, the 71016S12PHG8 is strictly a 5V device with VCC specification of 4.5 V to 5.5 V and TTL-compatible I/O thresholds. Its DC Electrical Characteristics table defines VIH ≥ 2.2 V and VIL ≤ 0.8 V referenced to 5V, and the Recommended Operating Conditions specify 5.0 V ± 10%. Interfacing to 3.3V systems requires level translation.
How does byte enable functionality work on the 71016S12PHG8?
The 71016S12PHG8 uses two independent active-low inputs - BHE (high-byte enable) and BLE (low-byte enable) - to control access to I/O8–I/O15 and I/O0–I/O7 respectively. As shown in the Truth Table, asserting only BLE enables low-byte writes/reads, only BHE enables high-byte operations, and both enables full 16-bit word access - eliminating need for read-modify-write sequences.
