Overview
The 71V3556SA133BQI is a static random-access memory component manufactured by Renesas Electronics. It features a storage organization of 128K x 36, providing a total capacity of 4 Mbit. The device operates with a maximum clock frequency of 133 MHz and has an access time of 4.2 ns. It utilizes a parallel interface and requires a power supply voltage ranging from 3.135 V to 3.465 V. The maximum power current is specified at 310 mA. The component supports an operating temperature range from -40°C to +85°C and is housed in a CABGA-165 package.
Feature Summary
- Zero Bus Turnaround (ZBT) technology eliminates dead cycles between read and write operations.
- Synchronous Single Data Rate (SDR) architecture with internally synchronized output buffers.
- Supports four-word burst capabilities for interleaved or linear access patterns.
Applications
- High-speed data buffering in telecommunications equipment
- Cache memory implementation in network routers and switches
- Data storage in industrial control systems requiring wide data buses
Procurement Notes
Verify the exact suffix designation, as official documentation lists variants such as 71V3556SA133BQI8. Confirm availability status, as this product line is subject to discontinuation notices. Ensure compliance with RoHS regulations, as indicated by specific manufacturer markings. Validate packaging type against procurement requirements, distinguishing between reel and tray configurations.
Selection Notes
Select this component when a 36-bit data width is required for system compatibility. The 133 MHz speed grade suits applications needing low latency without higher-frequency alternatives. Consider the CABGA-165 package for surface-mount assembly constraints. Verify that the 3.3V I/O logic levels match the host processor specifications.
Part Context
This part belongs to the 71V3556SA series of ZBT synchronous SRAMs. It shares architectural similarities with other members like the 71V3556SA100BQI and 71V3556SA133BG, differing primarily in speed grade and package style. The series is designed for pipelined applications requiring high throughput.
Replacement Considerations
Official substitutes include the 71V3556SA133BQI8 and 71V3556SA133BG. Verify pinout compatibility and electrical characteristics before substitution. Note that some variants may have different moisture sensitivity levels or packaging formats.
