IDT71V416VS12PH8

Memory IC Overview

The IDT71V416VS12PH8 is a 3.3V CMOS Static RAM organized as 256K x 16, providing a total storage capacity of 4 Megabits. It features a parallel interface with an access time of 12 ns and operates within a supply voltage range of 3.0 V to 3.6 V. The component utilizes a JEDEC center power and ground pinout for reduced noise and includes upper and lower byte enable pins for data masking. It is housed in a 44-pin, 400 mil plastic SOJ package and supports bidirectional LVTTL-compatible I/O.

Memory IC Feature Summary

• JEDEC center power and ground pinout configuration designed to minimize electrical noise during operation.
• Fully static asynchronous circuitry that requires no external clocks or periodic refresh cycles.
• Bidirectional inputs and outputs are directly compatible with LVTTL logic levels.
• Independent upper and lower byte enable pins allow for selective data masking.

Memory IC Applications

• High-speed memory buffering in embedded systems
• Cache memory implementation in microprocessor architectures
• Data storage in industrial control equipment

Memory IC Procurement Notes

Verify the specific suffix PH8 corresponds to the 44-pin SOJ package and Industrial temperature grade (-40°C to +85°C) when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as legacy IDT parts may have varying environmental declarations. Ensure the design accounts for the moisture sensitivity level specified in the datasheet before assembly.

Memory IC Selection Notes

Select this component for applications requiring fast asynchronous access with low power consumption via chip deselect. The 12 ns speed grade balances performance and power efficiency. Consider the 44-pin SOJ form factor for board space constraints. Verify compatibility with existing LVTTL logic families and ensure the single 3.3V supply rail meets system requirements.

Memory IC Part Context

This part belongs to the IDT71V416 family of high-speed SRAMs. The 'S' denotes standard power consumption, while 'L' variants offer low power options. The 'V' indicates commercial and industrial temperature ranges. Integrated Device Technology was acquired by Renesas Electronics, which now manages the product line under the Renesas brand.

Memory IC Replacement Considerations

Compatible substitutes include IDT71V416VL12PH8 (low power variant) and IDT71V416VS10PH8 (faster 10 ns speed). Cross-reference with Renesas 71V416 series equivalents ensuring identical pinouts and timing parameters.
