Product details
Overview
IDT71016S12PH8 from Integrated Device Technology is a 64K × 16-bit (1 Mbit) high-speed CMOS static RAM with 12 ns access time, TTL-compatible I/O, single 5V supply operation, and dual byte enable (BHE/BLE) for 8-bit subsystem interfacing - used in legacy industrial controllers and embedded memory buffers.
For engineers reviewing the IDT71016S12PH8 datasheet, IDT71016S12PH8 pinout, IDT71016S12PH8 application, or IDT71016S12PH8 equivalent, key selection criteria include 12 ns read access time, 44-pin plastic SOJ package compatibility, byte-selectable 16-bit data bus operation, and industrial temperature range support (–40°C to +85°C).
Technical Context
The IDT71016S12PH8 implements fully static asynchronous architecture with no clocks or refresh required. It supports three independent write-enable modes: chip-select-controlled, output-enable-controlled, and byte-enable-controlled timing, each with distinct setup/hold and pulse-width requirements verified per AC Electrical Characteristics Table 10.
Its bidirectional I/O structure uses TTL-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and drives outputs to VOH ≥ 2.4 V (IOH = –4 mA) and VOL ≤ 0.4 V (IOL = 8 mA), enabling direct interface with 5V microcontrollers and FPGAs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits), word-oriented addressing with A0–A15 inputs |
| Access Time (tAA) | 12 ns max - determines minimum address-to-data valid delay in read cycles |
| Supply Voltage | 5.0 V ±10% - compatible with standard 5V logic rails; no dual-supply or regulation needed |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Standby Current (ISB1) | 10 µA max at CMOS-level chip deselect - enables ultra-low-power hold mode |
| I/O Capacitance | CIN = 6 pF, CI/O = 7 pF - ensures signal integrity up to ~100 MHz bus frequencies |
| Output Enable Delay (tOE) | 7 ns max - defines fastest achievable read latency when OE is asserted |
Pinout & Package
Package: 44-pin Plastic SOJ (SO44-1), JEDEC-standard 400-mil body, gull-wing leads, lead-free compatible (per IDT documentation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus for full 64K-word decoding; no internal multiplexing |
| CS | Chip Select | Active-low enable; device enters standby (high-Z I/O, ISB1 = 10 µA) when high |
| OE | Output Enable | Active-low control of output drivers; tOE = 7 ns enables fast read burst capability |
| WE | Write Enable | Active-low write strobe; supports WE-controlled, CS-controlled, or byte-enable-controlled write cycles |
| BHE / BLE | Byte Enable | Independent high/low byte gating; allows 8-bit access without external demux |
| I/O0–I/O7 / I/O8–I/O15 | Bidirectional Data | TTL-compatible I/O pins; internally latched during writes, tristated when CS/OE/BHE/BLE inactive |
| VCC / VSS | Power / Ground | Single 5V supply; decoupling required per JEDEC SOJ layout guidelines |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62167EV30LL-12ZSXI | 12 ns access, 512K × 16 organization, 3.3V core (5V-tolerant I/O), TSOP II package | Higher density but requires voltage translation or dual-rail design; not drop-in compatible | Select only if migrating to 3.3V systems with board redesign; IDT71016S12PH8 remains optimal for pure 5V legacy designs |
| AS6C1008-12ZIN | 12 ns access, 128K × 8 organization, 5V-only, SOJ package, lower ICC (150 mA) | 8-bit bus width requires two devices for 16-bit interface; different pinout and byte enable logic | Use only for new 8-bit bus implementations; IDT71016S12PH8 provides native 16-bit width and BHE/BLE in one SOJ package |
Compared with CY62167EV30LL-12ZSXI and AS6C1008-12ZIN, the IDT71016S12PH8 delivers true 16-bit bus compatibility, industrial-qualified 5V operation, and pin-identical SOJ footprint - making it the sole option for maintaining legacy 5V controller memory subsystems without layout changes.

FAQ
What is the maximum operating temperature range for the IDT71016S12PH8?
The IDT71016S12PH8 is rated for industrial temperature operation from –40°C to +85°C. This specification is guaranteed across all AC and DC parameters in the datasheet, including 12 ns access time and 10 µA standby current. The device uses IDT's high-reliability CMOS process to maintain timing and leakage performance across this full range without derating.
Does the IDT71016S12PH8 require a refresh circuit or clock signal?
No, the IDT71016S12PH8 is a fully static RAM and requires no refresh circuitry or clock signal. Its asynchronous design uses only control inputs (CS, OE, WE, BHE, BLE) and address/data lines. All internal circuitry remains stable indefinitely while powered, making it ideal for battery-backed or fail-safe memory applications where clock failure must not corrupt data.
What package type is used for the IDT71016S12PH8?
The IDT71016S12PH8 uses a 44-pin plastic SOJ (Small Outline J-lead) package, designated SO44-1 in JEDEC standards. It features a 400-mil body width, gull-wing leads, and is compatible with standard SOJ socket footprints and wave-solder reflow profiles. This package was selected for high-pin-count reliability in dense industrial PCB layouts.
Can the IDT71016S12PH8 be used with 3.3V microcontrollers?
The IDT71016S12PH8 operates exclusively from a 5.0 V ±10% supply and has TTL-compatible I/O thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V). While its inputs accept 3.3V logic levels, its outputs drive to 2.4 V min (IOH = –4 mA), which may fall below the VIH requirement of some 3.3V receivers. Level-shifting or bus buffering is required for reliable 3.3V system integration.
How does byte enable functionality work on the IDT71016S12PH8?
The IDT71016S12PH8 uses independent BHE (high byte enable) and BLE (low byte enable) inputs to gate I/O8–I/O15 and I/O0–I/O7 respectively. When only BHE is active, only the upper byte is accessed; when only BLE is active, only the lower byte is accessed. Both must be active for full 16-bit word operations - enabling flexible 8-bit subsystem interfacing without external logic.
