Product details
Overview
71016S15PHG from Renesas Electronics is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 15 ns access time, TTL-compatible I/O, single 5 V supply operation, and byte-enable control for embedded memory subsystems in industrial controllers and communications equipment.
For engineers reviewing the 71016S15PHG datasheet, 71016S15PHG pinout, 71016S15PHG application, or 71016S15PHG equivalent, this device supports fast asynchronous read/write cycles, low-power standby modes, and JEDEC-standard 44-pin TSOP packaging - critical for legacy system refresh, FPGA co-processor buffering, and real-time data acquisition buffers.
Technical Context
The 71016S15PHG implements fully static asynchronous logic with no clocks or refresh required. It uses dual-byte enable (BHE/BLE) to support 8-bit sub-word access and features independent chip select (CS) and output enable (OE) for flexible bus timing control.
Its architecture delivers 15 ns address access time (tAA), 15 ns read cycle time (tRC), and 7 ns OE-to-output valid delay (tOE) under commercial temperature conditions (0°C to +70°C), all guaranteed at VCC = 5.0 V ±10% with TTL-level inputs and outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits), enabling word-aligned 16-bit data transfers without external multiplexing |
| Access Time (tAA) | 15 ns max - determines minimum CPU wait-state insertion for synchronous bus interfacing |
| Read Cycle Time (tRC) | 15 ns max - defines shortest interval between successive read operations on same address |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V TTL/CMOS logic rails without regulation overhead |
| I/O Interface | TTL-compatible bidirectional data bus (I/O₀–I/O₁₅) - eliminates level-shifter requirements in mixed-logic systems |
| Byte Enable Control | Separate BHE and BLE inputs - allows independent 8-bit upper/lower byte writes without masking logic |
| Standby Current (ISB) | 45 mA max (TTL-level CS inactive) - enables low-power sleep mode during processor idle periods |
Pinout & Package
71016S15PHG 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 by a notch or dot; package meets RoHS-compliant "Green" material requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A₀–A₁₅ | Address Inputs | 16-bit address bus accepting full 64K address space; no internal latching - requires stable address during CS active |
| CS | Chip Select | Active-low global enable; device enters high-Z output state when deasserted, reducing bus contention |
| OE | Output Enable | Active-low control for output drivers only; allows read data gating independent of CS or WE timing |
| WE | Write Enable | Active-low signal initiating write cycle; combined with CS and BLE/BHE to define write boundaries |
| BHE / BLE | Byte Enable Inputs | Independent controls for upper (I/O₈–I/O₁₅) and lower (I/O₀–I/O₇) data bytes - enables partial-word writes |
| I/O₀–I/O₁₅ | Bidirectional Data Bus | 16-bit TTL-compatible I/O lines; direction controlled implicitly by WE/CS state - no external direction pin needed |
| VCC / VSS | Power / Ground | Single 5 V supply with dedicated power/ground pairs per side - supports noise-sensitive high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Static Operation | No clock, no refresh, no dynamic timing constraints - simplifies interface design with microcontrollers and FPGAs |
| 15 ns Commercial Access Time | Enables zero-wait-state operation with 66 MHz Z80, 80C188, or similar legacy CPUs in industrial PLCs |
| Dual Byte Enable Architecture | Eliminates need for external byte-mask logic in 16-bit systems performing 8-bit peripheral register updates |
| TTL-Compatible I/O | Direct connection to 5 V microprocessor buses without level translation - reduces BOM count and layout complexity |
| Low Standby Power (45 mA) | Reduces thermal load in sealed enclosures and extends battery-backed operation in data loggers |

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 (8 Mbit), 45 ns access, 3.3 V core with 5 V tolerant I/O | Higher density but slower speed; requires voltage translation if interfacing exclusively with 5 V logic | Select when >1 Mbit capacity is needed and timing budget allows ≥45 ns latency |
| AS6C1008-55TIN | 128K × 8-bit (1 Mbit), 55 ns access, 5 V only, no byte enables | 8-bit organization requires external byte steering; lacks BHE/BLE - limits partial-write efficiency | Choose for cost-sensitive 8-bit bus systems where byte granularity is not required |
Compared with CY62167EV30LL-45ZSXIT and AS6C1008-55TIN, the 71016S15PHG uniquely balances 15 ns speed, 16-bit word width, dual byte enables, and native 5 V TTL compatibility - making it optimal for timing-critical upgrades of legacy 5 V embedded systems without redesigning bus logic.

FAQ
What is the operating temperature range for the 71016S15PHG?
71016S15PHG is rated for commercial temperature operation from 0°C to +70°C. It is packaged in a PHG44 TSOP and specified for 15 ns access time only within this range. Industrial-grade variants (e.g., 71016S15PHGI) exist but carry different orderable part numbers and temperature ratings.
Does the 71016S15PHG require an external clock or refresh circuitry?
No. The 71016S15PHG is a fully static RAM - it uses asynchronous CMOS circuitry with no clocks, no refresh cycles, and no dynamic timing constraints. Once powered and enabled, it retains data indefinitely as long as VCC remains within specification and CS is asserted during access.
How does byte enable functionality work on the 71016S15PHG?
The 71016S15PHG uses two independent inputs - BHE (high byte enable) and BLE (low byte enable) - to selectively activate I/O₈–I/O₁₅ or I/O₀–I/O₇ during write operations. When only one is low, only that 8-bit byte is written; both low enables full 16-bit word writes - eliminating need for external byte masking logic.
Can the 71016S15PHG be used with 3.3 V microcontrollers?
The 71016S15PHG operates strictly from a 5 V supply (4.5–5.5 V) and features TTL-compatible inputs (VIH ≥ 2.2 V, VIL ≤ 0.8 V), but its outputs swing to ~3.5 V (VOH min = 2.4 V at IOH = –4 mA). Direct interface with 3.3 V-only logic requires level translation or verification of receiver VIH/VIL compatibility per application.
What package type does the 71016S15PHG use, and is it RoHS compliant?
71016S15PHG uses a 44-pin Thin Small Outline Package (TSOP Type II), code PHG44, with 400-mil body width. Per Renesas documentation, it is a "Green" device - lead-free and compliant with RoHS Directive 2011/65/EU, with no intentionally added restricted substances.
