Product details
Overview
71016S15PHG8 from Renesas Electronics is a 64K × 16-bit (1,048,576-bit), high-speed CMOS static RAM with 15 ns access time, TTL-compatible I/O, single 5.0 V ±10% supply, and dual byte enable (BHE/BLE) for flexible 8-bit or 16-bit data bus interfacing - used in legacy industrial controllers, embedded instrumentation, and real-time data buffering systems.
For engineers reviewing the 71016S15PHG8 datasheet, 71016S15PHG8 pinout, 71016S15PHG8 application, or 71016S15PHG8 equivalent, this part supports asynchronous word/byte read-write operations with 7 ns OE access, 15 ns address access (tAA), and low-impedance output enable control - critical for timing-critical memory subsystems in non-refreshed architectures.
Technical Context
The 71016S15PHG8 implements fully static asynchronous operation with no clocks or refresh required. Its architecture includes independent row/column decoders, bidirectional TTL-compatible I/O buffers, and separate high-byte (I/O8–I/O15) and low-byte (I/O0–I/O7) drivers controlled by BHE and BLE inputs.
It uses CMOS technology with dynamic current draw up to 180 mA at fMAX and standby current as low as 10 µA under CMOS-level chip deselect (CS > VHC), enabling power-sensitive operation in battery-backed or thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1 Mbit); enables direct 16-bit parallel data transfers without external multiplexing |
| Access Time (tAA) | 15 ns max (Commercial grade); defines minimum address-to-valid-data delay in read cycles |
| Supply Voltage | 5.0 V ±10%; compatible with legacy 5 V TTL logic families without level translation |
| I/O Interface | TTL-compatible bidirectional data lines (I/O0–I/O15); eliminates need for external bus transceivers |
| Byte Enable Control | Dedicated BHE and BLE pins; allows independent 8-bit writes to upper/lower bytes without masking logic |
| Operating Temperature | 0°C to +70°C; validated for commercial-grade industrial equipment with ambient thermal cycling |
| Package Type | 44-pin TSOP Type II (PHG44); surface-mount footprint compatible with automated PCB assembly |
Pinout & Package
71016S15PHG8 is housed in a JEDEC-standard 44-pin Thin Small Outline Package (TSOP Type II), designated PHG44, with 400-mil body width and gull-wing leads. Pin 1 is marked via notch or dot; pin numbering follows standard counter-clockwise top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K memory locations; fully static - no setup/hold timing required |
| CS | Chip Select | Active-low enable; places device in active or high-Z standby mode; controls tACS and tCLZ timing |
| OE | Output Enable | Active-low control for output drivers; enables fast 7 ns read access while CS remains asserted |
| WE | Write Enable | Active-low write strobe; initiates write cycle when CS and byte enables are active |
| BHE / BLE | High/Low Byte Enable | Independent 8-bit write gating; permits partial-word writes without external byte masking logic |
| I/O0–I/O7 | Low-Byte Data I/O | Bidirectional 8-bit data path; driven during low-byte reads/writes; high-Z otherwise |
| I/O8–I/O15 | High-Byte Data I/O | Bidirectional 8-bit data path; driven during high-byte reads/writes; high-Z otherwise |
| VCC | Power Supply | +5.0 V ±10% main supply; powers core logic and I/O buffers; requires local decoupling |
| VSS | Ground | Signal and power ground reference; two dedicated pins reduce ground bounce in high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clock, no refresh - simplifies system timing design and eliminates DRAM controller overhead |
| 15 ns Commercial Access Time | Enables integration into 66 MHz CPU buses with minimal wait-state insertion |
| Dual Byte Enable (BHE/BLE) | Supports mixed 8-bit/16-bit peripheral interfacing without glue logic or data bus multiplexing |
| TTL-Compatible I/O | Direct connection to 5 V microcontrollers, FPGAs, and ASICs without level-shifting circuitry |
| Low Standby Current (10 µA) | Reduces quiescent power in sleep-mode applications such as portable test equipment and remote sensors |
Applications
| Industrial PLC Memory Buffer | Legacy Test Equipment Data Capture |
|---|---|
Use Scenario: Real-time acquisition of analog sensor streams in programmable logic controllers with deterministic scan cycles. IC Role / Device Role / Timing Role: High-reliability, non-refreshed data buffer storing intermediate process values between scan intervals. Use Value: 15 ns tAA ensures sub-microsecond memory access latency, preserving tight control loop timing without CPU wait states. |

IC Role / Device Role / Timing Role: First-stage circular buffer holding raw ADC samples prior to DMA transfer to host processor. Use Value: Bidirectional TTL I/O and byte-enable support allow seamless interface with 8-bit or 16-bit ADC/DAC buses without bus arbitration logic. |
| Embedded Instrumentation Firmware Storage | Communications Protocol Stack Buffer |
Use Scenario: Storing firmware configuration tables and calibration coefficients in handheld multimeters and power analyzers. IC Role / Device Role / Timing Role: Non-volatile shadow RAM holding modifiable runtime parameters with fast read/write capability. Use Value: Low ISB1 (10 µA) enables battery-backed retention during power-down without significant drain on backup cells. |
Use Scenario: Temporary storage of packetized serial data (e.g., Modbus RTU frames) in protocol gateways before CRC validation and forwarding. IC Role / Device Role / Timing Role: Asynchronous message staging buffer supporting variable-length frame assembly/disassembly. Use Value: Independent BHE/BLE control allows efficient handling of odd-length packets using only the required byte lanes, minimizing bus contention. |
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 | 512K × 16-bit, 45 ns access, 3.3 V supply; higher density but slower and incompatible voltage | Requires level translation and redesign of power delivery; unsuitable for 5 V-only systems | Select only if migrating to lower-power 3.3 V architecture and needing larger memory depth |
| AS6C1008-55PCN | 128K × 8-bit, 55 ns access, 5 V supply; narrower bus, slower speed, same voltage | Lacks byte-enable pins and 16-bit organization; needs external byte steering for 16-bit interfaces | Acceptable for cost-sensitive, non-timing-critical 8-bit systems where 15 ns performance is not required |
Compared with CY62167EV30LL-45ZSXIT and AS6C1008-55PCN, the 71016S15PHG8 uniquely delivers 15 ns 16-bit asynchronous access at 5 V with integrated byte enable - making it irreplaceable in legacy 5 V, timing-constrained designs without board rework.

FAQ
What is the operating temperature range for the 71016S15PHG8?
The 71016S15PHG8 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); that variant is designated 71016S15PHGI8. The PHG8 suffix explicitly indicates the commercial-grade TSOP package.
Does the 71016S15PHG8 require a refresh circuit?
No, the 71016S15PHG8 is a fully static RAM and requires no refresh circuitry. Its CMOS design uses latched flip-flop cells for data storage, enabling indefinite data retention as long as power is applied - a key advantage over DRAM in deterministic real-time systems.
Can the 71016S15PHG8 be used with a 3.3 V microcontroller?
The 71016S15PHG8 operates exclusively at 5.0 V ±10% and features TTL-compatible I/O thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V). Direct interface with 3.3 V logic is not recommended without level-shifting, as VOH min (2.4 V) may fall below 3.3 V receiver VIH requirements.
What is the meaning of the 'PHG8' suffix in 71016S15PHG8?
The 'PHG8' suffix identifies the package and packaging format: 'PH' = 400-mil TSOP Type II, 'G' = green (lead-free) construction, and '8' = tape-and-reel packaging. This matches Renesas' ordering nomenclature in the official datasheet's Orderable Part Information table.
How does byte enable (BHE/BLE) function during a write cycle in the 71016S15PHG8?
In the 71016S15PHG8, asserting BHE low enables writes to I/O8–I/O15, asserting BLE low enables writes to I/O0–I/O7, and asserting both enables full 16-bit writes. When only one is active, the other byte lane remains unchanged - allowing atomic partial-word updates without read-modify-write sequences.
