Overview
The Renesas Electronics Corporation 71V416L12PHGI is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) IC. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The device features a parallel interface and offers an access time of 12 ns. It is housed in a 44-pin Thin Small Outline Package (TSOP II) designed for surface-mount technology. The component supports an industrial operating temperature range from -40°C to +85°C.
Feature Summary
- Fully static asynchronous operation requiring no clock signals or data refresh cycles
- Bidirectional I/O pins compatible with LVTTL logic levels
- Center power and ground pinout configuration for improved signal integrity
Applications
- Industrial control systems requiring fast random-access memory
- Embedded applications within automotive electronics
- Telecommunications equipment utilizing asynchronous SRAM interfaces
Procurement Notes
Verify the specific suffix PHGI against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm current lifecycle status, as this part may be subject to obsolescence notices. Ensure compatibility with existing PCB footprints and verify moisture sensitivity level requirements during assembly processes.
Selection Notes
Select this component when a 12 ns access speed is required for 256K x 16 data organization. It is suitable for designs needing LVTTL-compatible inputs and a standard 3.3V supply. Consider the TSOP II package constraints regarding board space and thermal dissipation compared to BGA alternatives.
Part Context
This device belongs to the 71V416 series of high-speed CMOS static RAMs manufactured by Renesas Electronics. The series provides non-volatile-like performance without the complexity of flash programming. It serves as a general-purpose memory solution for microprocessor-based systems requiring rapid data retrieval and storage capabilities.
Replacement Considerations
Official substitutes include IDT71V416L10PHGI and IDT71V416L15PHGI. These variants share the same memory organization and package but differ in access times of 10 ns and 15 ns respectively.
