Overview
The Renesas Electronics 71V416S12PHGI8 is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) IC. It operates on a single 3.3V CMOS supply with a voltage range of 3.0V to 3.6V. The device features a parallel interface and offers a maximum access time of 12 ns. It is housed in a 44-pin Thin Shrink 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 periodic refresh cycles
- LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing
- Center power and ground pinout configuration to minimize noise and improve signal integrity
Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in microcontroller-based designs
- Industrial control system data storage
Procurement Notes
Verify the specific suffix PHGI8 against official Renesas documentation to confirm package type, lead finish, and environmental compliance status. Confirm current lifecycle status as distribution channels may list obsolete or end-of-life inventory. Ensure moisture sensitivity level (MSL 3) handling requirements are met during assembly to prevent package damage.
Selection Notes
Select this component when a 256K x 16 organization is required with 12 ns speed performance. It is suitable for designs needing LVTTL compatibility and center power/ground pins. Compare against the 71V416L series if lower power consumption is critical, noting that the 'S' series typically targets higher speed applications.
Part Context
This part belongs to the Renesas 71V416 family of 3.3V CMOS SRAMs. The 'S' designation indicates the speed grade (12 ns), while 'P' denotes the TSOP package. The 'HGI8' suffix specifies lead-free composition and tape-and-reel packaging. This family provides non-volatile-like reliability without the complexity of flash programming.
Replacement Considerations
Official substitutes include other variants within the 71V416S series with compatible speed grades and packages, such as the 71V416S10PHGI8 for faster access times, provided the pinout and electrical characteristics remain identical.
