Product details
Overview
IDT71T016SA12PHG from Integrated Device Technology is a 64K × 16-bit (1 Mbit), high-speed, single-supply 2.5V CMOS static RAM with 12 ns access and cycle times, LVTTL-compatible I/O, and independent upper/lower byte enables - used in embedded controllers, network packet buffers, and FPGA configuration memory.
For engineers reviewing the IDT71T016SA12PHG datasheet, IDT71T016SA12PHG pinout, IDT71T016SA12PHG application, or IDT71T016SA12PHG equivalent, key selection criteria include 2.5V operation, 12 ns read/write timing, byte-select capability, industrial temperature support (–40°C to +85°C), and FBGA-48 packaging compatibility.
Technical Context
The IDT71T016SA12PHG implements fully static asynchronous logic with no clocks or refresh required. It supports three distinct access modes: word-wide (BHE and BLE low), high-byte-only (BHE low, BLE high), and low-byte-only (BHE high, BLE low), each with guaranteed timing under industrial conditions.
All control inputs (CS, OE, WE, BHE, BLE) are active-low and LVTTL-compatible; bidirectional I/Os (I/O0–I/O15) drive and receive at 2.5V levels with 5 ns OE access and 4 ns tOH hold time. Power management includes dynamic standby (ISB = 40 mA max) and full static standby (ISB1 = 15 µA max) states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16-bit (1,048,576 bits) - supports 16-bit data bus interfacing without external multiplexing |
| Access Time (tAA) | 12 ns max (industrial range) - enables direct attachment to 83 MHz bus systems with setup margin |
| Supply Voltage | 2.375 V to 2.625 V - tightly regulated 2.5V domain compatible with modern low-voltage SoC interfaces |
| I/O Interface | LVTTL-compatible - interoperable with 2.5V logic families without level-shifting circuitry |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and networking equipment |
| Standby Current (ISB1) | 15 µA max - enables ultra-low-power retention during system sleep modes |
| Package | 48-ball FBGA (7 mm × 7 mm, 0.8 mm pitch) - compact footprint for space-constrained PCB layouts |
Pinout & Package
Package: 48-ball plastic FBGA (JEDEC standard BF48-1, 7 mm × 7 mm, 0.8 mm ball pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus for full 64K-word addressing; TTL-compatible thresholds (VIH ≥ 1.7 V, VIL ≤ 0.7 V) |
| CS | Chip Select (active low) | Primary enable for device selection; deactivates outputs and reduces current to ISB/ISB1 levels when high |
| OE | Output Enable (active low) | Controls output drivers only; allows read access while CS remains asserted (tOE = 6 ns max) |
| WE | Write Enable (active low) | Initiates write cycles; latches data on rising edge of WE when CS and byte enables are active |
| BHE | High-Byte Enable (active low) | Selects I/O8–I/O15 for 8-bit high-byte operations; enables partial writes without disturbing low byte |
| BLE | Low-Byte Enable (active low) | Selects I/O0–I/O7 for 8-bit low-byte operations; supports mixed-width data transfers in legacy systems |
| I/O0–I/O15 | Bidirectional Data I/O | 16-bit multiplexed data path; tri-stated when CS high or OE high; driven to VOH ≥ 1.7 V / VOL ≤ 0.7 V |
| VDD | Power Supply | Single 2.5V supply pin (two dedicated balls: E1 and D1 per FBGA layout); requires local decoupling |
| VSS | Ground | Ground reference (four dedicated balls: D2, E2, F1, F2); critical for noise immunity in high-speed reads |
Key Features
| Feature | Design Value |
|---|---|
| Byte-select architecture | Independent BHE/BLE controls allow 8-bit sub-word writes - eliminates read-modify-write overhead in microcontroller systems |
| Zero-power standby mode | ISB1 = 15 µA max ensures negligible leakage during power-gated states - extends battery life in portable industrial tools |
| Asynchronous static core | No clocks, no refresh, no wait states - simplifies timing closure and eliminates DRAM controller complexity |
| Industrial-grade reliability | Qualified over –40°C to +85°C with 100% burn-in and accelerated life testing - suitable for uncooled telecom line cards |
| FBGA thermal performance | 7 mm × 7 mm package with exposed thermal pad (ball A1–H8 perimeter) enables >1.2 W dissipation at 40°C ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress CY7C1019DV33-10ZSXI | 3.3V supply, 10 ns access, 1 Mbit (64K × 16), SOJ-44 only - no FBGA option | Requires 3.3V rail and level-shifting for 2.5V systems; incompatible with IDT71T016SA12PHG's voltage domain | Choose only if existing design uses 3.3V infrastructure and SOJ-44 footprint is fixed. |
| ISSI IS61WV102416BLL-12MLI | 2.5V supply, 12 ns access, 1 Mbit (64K × 16), 48-pin TSOP-II - different pinout and no FBGA variant | TSOP-II package increases board area by 42% vs. FBGA; lacks BHE/BLE pin mapping compatibility | Acceptable for cost-sensitive industrial boards where FBGA rework is prohibited and layout space permits. |
Compared with CY7C1019DV33-10ZSXI and IS61WV102416BLL-12MLI, the IDT71T016SA12PHG uniquely delivers industrial-qualified 2.5V operation in a compact 7 mm × 7 mm FBGA - enabling higher-density routing and lower EMI than TSOP/SOJ alternatives.

FAQ
What is the operating voltage range for IDT71T016SA12PHG?
IDT71T016SA12PHG operates from 2.375 V to 2.625 V - a tightly controlled 2.5V nominal supply. This range ensures compatibility with modern 2.5V logic families and avoids overvoltage stress that could trigger latch-up. The device draws ICC = 150 mA max during dynamic operation at VDD = 2.625 V and fMAX, and ISB1 = 15 µA max in full standby. Operation outside this range may cause data corruption or permanent damage.
Does IDT71T016SA12PHG support byte-level writes?
Yes, IDT71T016SA12PHG supports true byte-level writes via dedicated BHE (high-byte enable) and BLE (low-byte enable) pins. 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. This eliminates read-modify-write cycles in microcontroller-based systems. Both enables are active-low and fully specified for tBW = 8 ns max under industrial conditions.
What package type is used for IDT71T016SA12PHG?
IDT71T016SA12PHG uses a 48-ball plastic FBGA (JEDEC BF48-1) with 7 mm × 7 mm body size and 0.8 mm ball pitch. Pin assignments follow the standard FBGA top-view layout shown in Figure 3 of the datasheet (DSC-5326/02), including dual VDD (E1, D1) and quad VSS (D2, E2, F1, F2) for low-impedance power delivery. This package is not pin-compatible with SOJ-44 or TSOP-44 variants of the same family.
Is IDT71T016SA12PHG suitable for industrial temperature applications?
Yes, IDT71T016SA12PHG is fully qualified for industrial temperature operation from –40°C to +85°C. All AC parameters - including tAA = 12 ns, tRC = 12 ns, and tOE = 6 ns - are guaranteed across this range. DC characteristics such as VIH (≥1.7 V), VOL (≤0.7 V), and ISB1 (≤15 µA) are also specified for industrial conditions. Burn-in and HTOL testing confirm reliability in uncooled industrial enclosures.
How does the output enable (OE) function interact with chip select (CS) in IDT71T016SA12PHG?
In IDT71T016SA12PHG, OE controls output driver state independently of CS. When CS is low and OE is low, data appears on I/O pins after tOE = 6 ns max. When CS is low but OE is high, outputs enter high-Z - useful for bus sharing. When CS is high, the device enters standby regardless of OE state, reducing ICC to ISB or ISB1 levels. This two-level control enables flexible bus arbitration without disabling the entire memory subsystem.
