Product details
Overview
IDT71016S15PH 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 sub-word access - used in legacy industrial controllers, embedded instrumentation buffers, and FPGA configuration memory subsystems.
For engineers reviewing the IDT71016S15PH datasheet, IDT71016S15PH pinout, IDT71016S15PH application, or IDT71016S15PH equivalent, key selection criteria include verified 15 ns read cycle timing, SOJ-44 package compatibility, byte-selectable I/O control, and industrial temperature range (–40°C to +85°C) support without refresh circuitry.
Technical Context
The IDT71016S15PH implements fully static asynchronous architecture with no clocks or refresh required. Its address decoding supports full 16-bit word reads/writes and independent upper- or lower-byte operations via BHE and BLE control signals.
It uses TTL-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and delivers VOH ≥ 2.4 V at –4 mA and VOL ≤ 0.4 V at 8 mA, enabling direct interface with 5 V microcontrollers and FPGAs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits), fixed word width for parallel bus interfacing |
| Access Time (tAA) | 15 ns max - guarantees data valid within 15 ns of stable address under industrial conditions |
| Read Cycle Time (tRC) | 15 ns max - defines minimum interval between successive read operations |
| Supply Voltage | 5.0 V ± 10% - operates from standard logic rail; no auxiliary supplies needed |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Package | 44-pin Plastic SOJ (SO44-1), 400-mil width - JEDEC-standard footprint for socketed or soldered mounting |
| Dynamic Current (ICC) | 180 mA max at fMAX - enables power budgeting for burst-access memory subsystems |
Pinout & Package
44-pin Plastic SOJ (SO44-1) package per JEDEC MS-025, 400-mil body width, gull-wing leads, lead finish SnPb. Pin 1 marked by notch or dot; top view shown in datasheet Figure 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus interface; fully decoded to select one of 64K locations |
| CS | Chip Select | Active-low enable; device enters standby (high-Z I/O, low ISB) when high |
| OE | Output Enable | Active-low; controls output drivers only - does not affect internal state or write path |
| WE | Write Enable | Active-low; initiates write cycle when CS and byte enables are active |
| BHE / BLE | Byte Enable Inputs | Independent control of upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes |
| I/O0–I/O15 | Bidirectional Data I/O | TTL-compatible 16-bit data bus; direction controlled by WE and CS state |
| VCC / VSS | Power / Ground | Single 5 V supply; decoupling required per high-speed SRAM layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Equal access and cycle times | 15 ns tAA = tRC - simplifies timing analysis and eliminates worst-case pipeline stalls |
| Dual byte enable (BHE/BLE) | Enables 8-bit sub-word writes without masking or extra logic - reduces bus contention in mixed-width systems |
| TTL-compatible I/O | Direct interface with 5 V MCUs, CPLDs, and legacy ASICs - no level translators required |
| Low standby current (ISB1) | 10 µA max at CMOS-level CS deassertion - supports low-power sleep modes in battery-backed systems |
| Fully static operation | No clocks, no refresh, no hidden cycles - deterministic latency and zero maintenance overhead |
Applications
| Industrial PLC Data Buffers | FPGA Configuration Memory |
|---|---|
|

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 | 512K × 16-bit, 45 ns access, 3.3 V core with 5 V tolerant I/O | Higher density but slower speed; requires voltage translation if system lacks 3.3 V rail | Select only if board has 3.3 V supply and timing budget permits >3× longer access latency |
| AS6C1008-15PCN | 128K × 8-bit, 15 ns access, 5 V-only, 32-pin SOP | Narrower data bus (8-bit), smaller package (32-pin vs 44-pin), no byte enables | Use only for cost-sensitive 8-bit bus upgrades where BHE/BLE functionality is unused and PCB layout allows SOP-32 substitution |
Compared with CY62167EV30LL-45ZXC and AS6C1008-15PCN, the IDT71016S15PH uniquely delivers 16-bit width, true 15 ns performance at 5 V, and dual byte enables in a JEDEC-standard SOJ-44 package - making it irreplaceable for maintaining timing-critical industrial designs originally specified with this part.

FAQ
What is the operating temperature range for the IDT71016S15PH?
The IDT71016S15PH is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the "Recommended Operating Temperature and Supply Voltage" table (Table 4) and applies to all AC and DC electrical characteristics listed for the S15 speed grade. The IDT71016S15PH maintains full timing compliance across this full range without derating.
Does the IDT71016S15PH require a clock or refresh signal?
No, the IDT71016S15PH uses fully static asynchronous circuitry and requires no clock, refresh, or hidden maintenance cycles. Data retention is indefinite as long as VCC is applied and ambient temperature remains within spec. This is explicitly stated in the "Description" section and confirmed by the absence of any clock-related pins or timing parameters in the datasheet.
What is the function of the BHE and BLE pins on the IDT71016S15PH?
BHE (High Byte Enable) and BLE (Low Byte Enable) are independent active-low inputs that control access to the upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes. When only one is asserted, the corresponding 8-bit portion is read from or written to while the other remains high-impedance - enabling efficient 8-bit transfers on a 16-bit bus. This behavior is defined in the Truth Table (Table 2).
Is the IDT71016S15PH pin-compatible with other speed grades in the IDT71016 family?
Yes, the IDT71016S15PH shares identical pinout and package (44-pin SOJ) with IDT71016S12PH and IDT71016S20PH. All variants use the same SO44-1 footprint and functional pin mapping per the "Pin Configurations" diagram and "Pin Descriptions" table. Only timing parameters differ between speed grades.
What is the maximum output drive strength of the IDT71016S15PH I/O pins?
The IDT71016S15PH guarantees VOH ≥ 2.4 V at IOH = –4 mA and VOL ≤ 0.4 V at IOL = 8 mA under minimum VCC (4.5 V). These values are specified in the "DC Electrical Characteristics" table (Table 7) and confirm robust TTL-compatible drive capability sufficient for driving multiple 74LS inputs or standard 5 V FPGA I/O banks.
