Product details
Overview
71016S20YGI from Renesas Electronics is a 64K × 16-bit (1,048,576-bit) high-speed CMOS static RAM with 20 ns read/write cycle time, TTL-compatible I/O, single 5.0 V ±10% supply operation, and industrial temperature range (–40°C to +85°C). It serves as a non-refreshing, asynchronous memory buffer in real-time control systems requiring deterministic access timing.
For engineers reviewing the 71016S20YGI datasheet, 71016S20YGI pinout, 71016S20YGI application, or 71016S20YGI equivalent, key selection criteria include byte-enable-controlled 16-bit word/byte write capability, 44-pin SOJ (PBG44) package compatibility, low-standby current (45 mA max), and guaranteed 20 ns AC timing under industrial conditions.
Technical Context
The 71016S20YGI implements fully static asynchronous circuitry-no clocks or refresh required-and uses dual byte enable (BHE/BLE) for independent high/low byte writes. Its address access time (tAA) and chip select access time (tACS) are both rated at ≤20 ns over the full industrial temperature range.
It features three distinct enable controls: Chip Select (CS), Output Enable (OE), and Write Enable (WE), enabling flexible bus arbitration. All 16 bidirectional I/O pins (I/O0–I/O15) are TTL-compatible with VOH ≥2.4 V and VOL ≤0.4 V at specified load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit = 1,048,576 bits; supports full-word or byte-level data transfers without external logic. |
| Access/Cycle Time | 20 ns max (industrial grade); ensures deterministic latency for real-time microcontroller or DSP memory interfaces. |
| Supply Voltage | 5.0 V ±10% (4.5–5.5 V); compatible with legacy 5 V logic families and eliminates need for level-shifting. |
| Operating Temperature | –40°C to +85°C; qualified for industrial automation, motor control, and embedded instrumentation environments. |
| Standby Current | 45 mA max (ISB, TTL-level CS deassertion); enables low-power hold mode during processor sleep states. |
| I/O Interface | TTL-compatible inputs/outputs; drives standard 5 V bus loads without external buffers or translators. |
| Package | 44-pin Plastic SOJ (PBG44); JEDEC-standard footprint with 0.050" lead pitch, suitable for wave-soldered industrial PCBs. |
Pinout & Package
71016S20YGI is housed in a 44-pin Plastic SOJ (PBG44) package per JEDEC MS-025. Pin layout is identical for SOJ and TSOP variants, supporting drop-in replacement across package types where board space permits.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus interface; selects one of 64K memory locations; no internal latching required. |
| CS | Chip Select | Active-low global enable; places device in active or high-Z standby based on logic level; supports multi-chip memory decoding. |
| OE | Output Enable | Active-low control for output drivers; allows shared bus operation with other devices; tOE ≤10 ns ensures fast read response. |
| WE | Write Enable | Active-low write strobe; initiates write cycle when CS and BHE/BLE are also asserted; tWP ≥12 ns minimum pulse width. |
| BHE / BLE | Byte Enable | Independent high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7) write controls; enables partial-word updates without read-modify-write. |
| I/O0–I/O15 | Bidirectional Data I/O | 16-bit TTL-compatible data bus; tri-state capable; supports simultaneous read/write arbitration via OE/WE timing. |
| VCC | Power Supply | +5.0 V ±10% supply input; decoupling recommended near pin for noise immunity in high-speed operation. |
| VSS | Ground | Signal and power ground reference; two dedicated pins reduce ground bounce in burst-access scenarios. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clock, no refresh, no wait states-simplifies timing-critical MCU or FPGA memory controller design. |
| Byte-Enable Write Architecture | Independent BHE/BLE pins allow selective 8-bit writes to upper or lower byte without disturbing adjacent data. |
| Industrial Temperature Qualification | Full 20 ns timing guaranteed from –40°C to +85°C; validated for use in motor drives and PLC backplanes. |
| Low Standby Power | ISB1 = 10 µA (CMOS-level CS deassertion); reduces system power in idle states without sacrificing wake-up speed. |
| TTL-Compatible I/O | VOH ≥2.4 V / VOL ≤0.4 V at 5 V supply; interoperable with legacy 5 V microcontrollers, FPGAs, and ASICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-20ZSXI | 64K × 16-bit, 20 ns, 3.3 V core (with 5 V tolerant I/O); lower ICC (120 mA vs 170 mA), different package (44-pin TSOP II). | Requires voltage translation or mixed-supply design; not suitable for pure 5 V systems without level shifters. | Select only if migrating to 3.3 V system architecture; verify I/O voltage tolerance against host bus drivers. |
| AS6C1008-20ZIN | 64K × 16-bit, 20 ns, 5 V supply; higher ISB (100 µA vs 45 mA), same PBG44 SOJ package and pinout. | Higher standby current limits battery-backed or low-power hold modes; otherwise functionally interchangeable. | Prefer for cost-sensitive industrial upgrades where standby power is non-critical and SOJ footprint must be preserved. |

FAQ
What is the operating temperature range for the 71016S20YGI?
The 71016S20YGI is rated for industrial operation from –40°C to +85°C. This specification is validated across all AC and DC parameters-including 20 ns access time, 45 mA standby current, and TTL-compatible I/O levels-ensuring consistent performance in harsh environments like factory floors or outdoor control cabinets.
Does the 71016S20YGI require a refresh circuit or clock signal?
No, the 71016S20YGI is a fully static RAM using asynchronous CMOS circuitry. It operates without clocks, timers, or periodic refresh cycles-simplifying integration into microcontroller, FPGA, or ASIC-based systems where deterministic timing and minimal external support logic are essential.
What package type does the 71016S20YGI use, and is it JEDEC-compliant?
The 71016S20YGI uses a 44-pin Plastic SOJ (PBG44) package conforming to JEDEC MS-025. Its pinout matches the 44-pin TSOP II variant (PHG44), enabling mechanical interchangeability where board layout permits-though soldering profiles differ between SOJ and TSOP.
Can the 71016S20YGI perform byte-level writes independently?
Yes, the 71016S20YGI supports independent high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7) writes via dedicated BHE and BLE pins. This eliminates the need for read-modify-write sequences when updating partial words-critical for efficient register or configuration memory updates in real-time systems.
Is the 71016S20YGI compatible with 5 V TTL logic families?
Yes, the 71016S20YGI features fully TTL-compatible inputs and outputs: VIH ≥2.2 V, VIL ≤0.8 V, VOH ≥2.4 V (at –4 mA), and VOL ≤0.4 V (at 8 mA). This ensures direct interfacing with legacy 5 V microcontrollers, CPLDs, and bus transceivers without level-shifting components.
