Product details
Overview
IDT71V124SA10YGI8 from Integrated Device Technology is a 128K × 8 (1 Mbit), 3.3 V high-speed CMOS static RAM with 10 ns access and cycle times, JEDEC center power/ground pinout for noise reduction, LVTTL-compatible I/O, and industrial temperature support (–40°C to +85°C). It serves as fast, asynchronous, non-refresh memory in embedded controllers, network packet buffers, and real-time data acquisition systems.
For engineers reviewing the IDT71V124SA10YGI8 datasheet, IDT71V124SA10YGI8 pinout, IDT71V124SA10YGI8 application, or IDT71V124SA10YGI8 equivalent, key selection criteria include its 10 ns tAA/tRC timing, single 3.3 V supply operation, low 5 ns tOE, 32-pin TSOP Type II package, and industrial-grade reliability without refresh circuitry.
Technical Context
The IDT71V124SA10YGI8 implements fully static asynchronous logic-no clocks or refresh required-and uses IDT's high-reliability CMOS process to achieve 10 ns read/write cycle times across industrial temperatures. Its dual-control architecture supports both chip-select–driven and output-enable–driven timing modes, with tCLZ = 4 ns and tOHZ = 5 ns ensuring fast bus turnaround.
JEDEC-compliant center power/ground pinout (VDD on pin 24, GND on pin 13) minimizes simultaneous switching noise, while LVTTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max) and outputs (VOH = 2.4 V min at –4 mA, VOL = 0.4 V max at 8 mA) ensure interoperability with 3.3 V logic families without level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 8-bit (1,048,576 bits), byte-wide parallel interface |
| Access Time (tAA) | 10 ns maximum - enables ≤100 MHz random read bursts in synchronous bus interfaces |
| Read Cycle Time (tRC) | 10 ns maximum - supports sustained 100 MT/s throughput with no wait states |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62128EV30LL-10ZSXIT | 128K × 8, 3.3 V, 10 ns, but uses corner VDD/GND pinout and has higher ICC (165 mA vs. 145 mA) | Higher noise sensitivity in dense routing; requires additional decoupling near pins 1/32 | Select if Cypress toolchain or legacy board reuse drives compatibility |
| AS6C1008-10TIN | 128K × 8, 3.3 V, 10 ns, but rated only for commercial temp (0°C to +70°C); no industrial grade option | Not qualified for extended temperature deployments; fails DO-160 or IEC 60068-2-14 testing | Select only for cost-sensitive consumer or lab equipment with controlled ambient |
Compared with CY62128EV30LL-10ZSXIT and AS6C1008-10TIN, the IDT71V124SA10YGI8 uniquely combines industrial temperature qualification, JEDEC center-power noise suppression, and lowest standby current (10 µA), making it optimal for ruggedized, low-power, high-integrity systems where timing determinism and EMI resilience are critical.

FAQ
What is the guaranteed operating temperature range for IDT71V124SA10YGI8?
IDT71V124SA10YGI8 is fully specified and tested over the industrial temperature range of –40°C to +85°C. This includes all DC and AC electrical characteristics such as tAA, tRC, ICC, and ISB1. The "I" suffix in the part number explicitly denotes industrial qualification, and the YGI8 package code confirms RoHS-compliant TSOP packaging rated for this range.
Does IDT71V124SA10YGI8 require a refresh circuit or clock signal?
No, IDT71V124SA10YGI8 is a fully static CMOS SRAM and requires neither a clock nor periodic refresh cycles. Its internal latches retain data indefinitely as long as VDD remains within specification and CS is held high during standby. This eliminates timing-critical refresh overhead in microcontroller or FPGA-based systems.
What is the meaning of "YGI8" in the IDT71V124SA10YGI8 part number?
In IDT71V124SA10YGI8, "Y" indicates tape-and-reel packaging, "G" denotes lead-free (RoHS-compliant) finish, "I" specifies industrial temperature range, and "8" identifies the 32-pin Type II TSOP (SO32-4) package. This matches the ordering information diagram in the official datasheet DSC-3873/09.
Can IDT71V124SA10YGI8 be used with 5 V logic interfaces?
No - IDT71V124SA10YGI8 is strictly a 3.3 V LVTTL device. Its absolute maximum input voltage is VDD + 0.5 V (≤4.1 V), and VIH minimum is 2.0 V. Direct connection to 5 V logic risks damage or undefined behavior. Level-shifting circuitry or 3.3 V–compatible controllers (e.g., ARM Cortex-A/M series, Xilinx Zynq PS, Intel MAX 10) are required.
How does the center power/ground pinout improve system performance in IDT71V124SA10YGI8?
The JEDEC-standard center VDD (pin 24) and GND (pin 13) placement in IDT71V124SA10YGI8 reduces loop inductance and simultaneous switching output (SSO) noise by up to 40% compared to corner-supply layouts. This improves signal integrity on shared data/address buses and lowers the risk of metastability in high-speed read/write transitions.
