Overview
The 71V256SA15PZG8 is a 3.3V CMOS Asynchronous Static RAM organized as 32K x 8, providing a total storage capacity of 256Kb. It features a parallel interface with a maximum access time of 15 ns and operates within a supply voltage range of 3V to 3.6V. The device utilizes fully static asynchronous circuitry, eliminating the need for clocks or refresh cycles. It is housed in a 28-pin TSOP package and supports commercial temperature grades.
Feature Summary
- Fully static asynchronous architecture requiring no clock signals or refresh operations
- Low standby power consumption ensuring extended battery life in portable applications
- LVTTL-compatible inputs and outputs for direct interfacing with standard logic families
Applications
- High-performance processor secondary cache systems
- Battery-powered devices requiring low standby current
- General-purpose memory buffering in embedded systems
Procurement Notes
Verify component authenticity through authorized Renesas distributors due to obsolete status. Confirm RoHS compliance and lead-free specifications against current datasheets. Check for moisture sensitivity level (MSL) handling requirements prior to assembly. Validate that the specific suffix denotes tape-and-reel packaging suitable for automated surface-mount processes.
Selection Notes
Select this component when a 15 ns access time meets system timing constraints without requiring synchronous interfaces. Ensure the design accommodates the 3.3V supply rail and LVTTL logic levels. Consider the 28-TSOP footprint for PCB layout compatibility. Evaluate thermal performance within the specified commercial operating temperature range during integration.
