Product details
Overview
IDT71016S15PH8 from Integrated Device Technology is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 15 ns access time, 5 V single-supply operation, TTL-compatible I/O, and dual byte enable (BHE/BLE) for 8-bit subsystem interfacing - used in legacy industrial controllers, embedded instrumentation buffers, and FPGA configuration memory.
For engineers reviewing the IDT71016S15PH8 datasheet, IDT71016S15PH8 pinout, IDT71016S15PH8 application, or IDT71016S15PH8 equivalent, key selection criteria include 15 ns read cycle time, SOJ-44 package compatibility, byte-selectable write capability, and industrial temperature range (–40°C to +85°C) support.
Technical Context
The IDT71016S15PH8 implements fully static asynchronous architecture with no clocks or refresh required. Its address access time (tAA) and read cycle time (tRC) are both rated at 15 ns across the industrial temperature range, and it supports independent high- and low-byte writes via dedicated BHE and BLE control inputs.
All 16 bidirectional I/O lines are TTL-compatible with VOH ≥ 2.4 V (IOH = –4 mA) and VOL ≤ 0.4 V (IOL = 8 mA), and chip deselect reduces current draw to ISB1 = 10 mA under CMOS-level standby conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits), enabling word-wide data transfers without external multiplexing |
| Access Time (tAA) | 15 ns max over –40°C to +85°C, defining minimum address-to-data-valid latency in read cycles |
| Read Cycle Time (tRC) | 15 ns max, setting shortest interval between successive read operations |
| Supply Voltage | 5.0 V ± 10% (4.5–5.5 V), compatible with legacy 5 V logic systems and eliminating level-shifting needs |
| Standby Current (ISB1) | 10 µA max under CMOS-level chip disable (CS > VHC), enabling low-power hold mode |
| Operating Temperature | –40°C to +85°C industrial grade, validated for use in uncontrolled ambient environments |
| I/O Interface | TTL-compatible inputs and outputs, ensuring direct connection to 74LS/74F logic families without interface buffers |
Pinout & Package
Package: 44-pin Plastic SOJ (SO44-1), JEDEC-standard 400-mil width, surface-mount, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus accepting full 64K-word space; no internal latching or multiplexing |
| CS | Chip Select | Active-low global enable; device enters standby (high-Z I/O, low ICC) when high |
| OE | Output Enable | Active-low control for output drivers; enables read data only when CS and OE are low |
| WE | Write Enable | Active-low signal initiating write cycles; combined with BHE/BLE to select byte lanes |
| BHE / BLE | Byte Enable (High/Low) | Independent controls for upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes during writes |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit TTL-compatible I/O lines; direction controlled by WE and CS state, not external direction signals |
| VCC / VSS | Power / Ground | Single 5 V supply; requires local decoupling due to 210 mA dynamic ICC at fMAX |
Key Features
| Feature | Design Value |
|---|---|
| Equal tAA and tRC timing | 15 ns read cycle symmetry simplifies timing budget allocation in synchronous bus designs |
| Dual byte write enable | BHE/BLE pins allow partial-word writes without read-modify-write sequences or external gating logic |
| TTL-compatible I/O | Direct interface to legacy microprocessor buses (e.g., 80C186, 68000) without level translators |
| Low standby power (ISB1) | 10 µA CMOS-level standby current enables battery-backed retention in power-constrained systems |
| Industrial temperature range | Validated operation from –40°C to +85°C supports deployment in motor drives, PLCs, and outdoor equipment |

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-45ZXC | 128K × 16-bit, 45 ns access, 3.3 V supply, TSOP-44 package | Higher density but slower speed and different voltage domain; requires level translation in 5 V systems | Select only if migrating to 3.3 V architecture and needing >1 Mbit capacity |
| AS6C1008-15PCN | 128K × 8-bit, 15 ns access, 5 V supply, SOJ-32 package | 8-bit bus width and 32-pin SOJ require PCB redesign; lacks BHE/BLE for byte masking | Consider only for cost-sensitive upgrades where bus width reduction and layout change are acceptable |
Compared with CY62167EV30LL-45ZXC and AS6C1008-15PCN, the IDT71016S15PH8 uniquely delivers 15 ns 5 V operation in SOJ-44 with native byte-enable control - making it the sole drop-in replacement for legacy 64K × 16 designs requiring no voltage or layout changes.

FAQ
What is the operating temperature range of the IDT71016S15PH8?
The IDT71016S15PH8 is specified for industrial temperature operation from –40°C to +85°C. This range is validated per the manufacturer's DC and AC electrical characteristics tables and applies to all timing parameters including tAA = 15 ns and tRC = 15 ns. The part carries the 'I' suffix in its ordering code, confirming industrial qualification.
Does the IDT71016S15PH8 require a clock or refresh signal?
No, the IDT71016S15PH8 uses fully static CMOS circuitry and requires neither a clock nor periodic refresh. It retains data indefinitely as long as VCC is maintained within 4.5–5.5 V and ambient temperature remains within –40°C to +85°C. This eliminates timing-critical refresh overhead in microcontroller or FPGA-based systems.
What package type does the IDT71016S15PH8 use?
The IDT71016S15PH8 uses a 44-pin Plastic SOJ (Small Outline J-lead) package, designated SO44-1 per JEDEC standards. It features a 400-mil body width, gull-wing leads, and is compatible with standard SOJ reflow profiles. The 'PH' in the part number explicitly denotes this SOJ packaging variant.
Can the IDT71016S15PH8 perform byte-wide writes?
Yes, the IDT71016S15PH8 supports independent byte-wide writes using the BHE (high byte enable) and BLE (low byte enable) inputs. When BHE is low and BLE is high, only I/O8–I/O15 are written; when BLE is low and BHE is high, only I/O0–I/O7 are written - enabling efficient partial-word updates without read-modify-write cycles.
Is the IDT71016S15PH8 still recommended for new designs?
No - the original IDT datasheet (February 2001 revision) removed the "Not recommended for new designs" notice, but IDT discontinued this product line after its acquisition by Renesas. Aetrix Electronics supplies remaining factory stock with full traceability; design-in is appropriate only for legacy repair, sustainment, or obsolescence mitigation programs.
