AS4C16M16SA-6TCNTR

Memory IC Overview

The AS4C16M16SA-6TCNTR is a 256 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Alliance Memory. It features a 16-bit data bus width and an organization of 16M x 16. The device supports a maximum clock frequency of 166 MHz with a typical access time of 5 ns. It operates within a voltage range of 3 V to 3.6 V and is housed in a 54-pin TSOP-II package. The component is rated for commercial temperature operation, spanning from 0°C to +70°C.

Memory IC Feature Summary

• Supports high-speed synchronous data transfer via a 16-bit interface at frequencies up to 166 MHz.
• Provides 256 Mbit storage capacity organized as 16M words by 16 bits.
• Operates on a single 3.3V power supply with a specified range of 3V to 3.6V.

Memory IC Applications

• General-purpose data buffering in embedded systems
• Cache memory implementation in consumer electronics
• Graphics frame buffer applications

Memory IC Procurement Notes

Verify the suffix TCNTR indicates tape and reel packaging when ordering. Confirm the -6 speed grade corresponds to the required 166 MHz performance. Ensure the commercial temperature range meets system requirements. Check RoHS compliance status if restricted substances are a constraint. Validate pinout compatibility with the target PCB footprint.

Memory IC Selection Notes

Select this part for designs requiring 256 Mbit density with a 16-bit interface. The TSOP-II package suits surface-mount assembly processes. Consider the 5 ns access time for timing constraints. Evaluate thermal management for the commercial temperature range. Compare against other SDRAM options if higher densities or different bus widths are needed.

Memory IC Part Context

This component belongs to the AS4C16M16SA series of SDRAM devices. It shares architectural similarities with other members like the AS4C16M16SA-6TIN, differing primarily in operating temperature range and packaging format. The series is designed for general-purpose memory applications requiring moderate speed and density.

Memory IC Replacement Considerations

AS4C16M16SA-6BAN offers automotive temperature rating and BGA packaging. AS4C16M16SA-6TIN provides industrial temperature range in TSOP-II. Verify electrical compatibility before substitution.
