Product details
Overview
71V016SA20PHG from Renesas Electronics is a 1 Mbit (64K × 16) high-speed CMOS static RAM with 20 ns read/write cycle time, single 3.3 V supply operation, industrial temperature range (–40°C to +85°C), and LVTTL-compatible bidirectional I/O. It serves as fast, non-refreshing data buffer or working memory in real-time control systems requiring deterministic timing.
For engineers reviewing the 71V016SA20PHG datasheet, 71V016SA20PHG pinout, 71V016SA20PHG application, or 71V016SA20PHG equivalent, key selection criteria include access time consistency across CS/OE/BE control paths, byte-enable granularity for 8-bit subsystem interfacing, and low-impedance output drive under 3.3 V LVTTL logic levels.
Technical Context
The 71V016SA20PHG implements fully static asynchronous architecture-no clocks or refresh required-with independent chip select (CS), output enable (OE), write enable (WE), and dual byte enables (BHE/BLE) enabling flexible word/byte read-write control. Its internal decoders and sense amplifiers support simultaneous address decoding and fast data latching without pipeline stalls.
All inputs meet LVTTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), outputs drive ±4 mA/±8 mA loads with VOH ≥ 2.4 V and VOL ≤ 0.4 V at VDD = 3.15 V, and dynamic standby current is limited to 30 mA at maximum frequency-critical for power-constrained embedded controllers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-20ZSXI | 512K × 16 organization, 20 ns speed, 3.3 V supply, same TSOP-44 package | Lower density (512K vs. 1M); suitable where memory footprint is constrained but bandwidth suffices | Select when board space limits FBGA/SOJ options and 512K capacity meets firmware/data table requirements |

FAQ
What is the maximum operating frequency supported by the 71V016SA20PHG?
The 71V016SA20PHG supports a maximum read/write cycle rate of 50 MHz, derived from its 20 ns tRC specification. This allows sustained data transfer at 800 MB/s (16-bit × 50 MHz) in burst configurations. The device does not require clocks or refresh, so timing is governed solely by external address and control signal stability-not internal oscillator constraints.
Does the 71V016SA20PHG require external refresh circuitry?
No, the 71V016SA20PHG is a fully static RAM and requires no refresh circuitry. 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. This eliminates refresh overhead and timing uncertainty present in DRAM-based solutions.
Can the 71V016SA20PHG be used with 5 V logic interfaces?
No-the 71V016SA20PHG 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 may damage inputs or cause undefined behavior. Level translation (e.g., TXB0108 or discrete MOSFET translators) is required for mixed-voltage systems.
What is the function of the BHE and BLE pins on the 71V016SA20PHG?
The BHE (High Byte Enable) and BLE (Low Byte Enable) pins on the 71V016SA20PHG independently control write operations to the upper (I/O8–I/O15) and lower (I/O0–I/O7) byte lanes. When asserted low with WE low, they allow selective 8-bit writes without reading-modifying-writing the full 16-bit word-reducing bus traffic and improving efficiency in byte-oriented protocols like Modbus or CAN FD payload handling.
Is the 71V016SA20PHG available in lead-free and RoHS-compliant packaging?
Yes, the 71V016SA20PHG is offered in green (halogen-free, RoHS-compliant) variants. Per Renesas ordering information, the "G" suffix in the part number (e.g., PHG → PHG) denotes compliance with JEDEC J-STD-609A Class 1 moisture sensitivity and EU RoHS Directive 2011/65/EU. Full material declarations are available via Renesas' Product Change Notification (PCN) database.
