IS42S16100C1-6T

Memory IC Overview

The IS42S16100C1 is a 16-Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by ISSI. It features an organization of 524,288 words by 16 bits across two independent banks. The device supports operating frequencies of 200 MHz, 166 MHz, and 143 MHz with a single 3.3V power supply and LV TTL interface. Available in 50-pin TSOP-II and 60-ball fBGA packages, it offers industrial temperature range options up to 143 MHz.

Memory IC Feature Summary

• Dual internal bank architecture allowing simultaneous and independent operation
• Fully synchronous pipeline design with all signals referenced to the positive clock edge
• Configurable burst lengths including sequential and interleave sequences
• Supports programmable CAS latency and byte control via LDQM/UDQM pins

Memory IC Applications

• High-speed data buffering in embedded systems
• Graphics memory for display controllers
• Cache memory in network equipment
• General-purpose volatile storage in consumer electronics

Memory IC Procurement Notes

Verify the specific speed grade suffix (-5, -6, or -7) required for your target clock frequency. Confirm package selection between TSOP-II and fBGA based on board space constraints. Ensure compatibility with 3.3V logic levels and check for lead-free packaging requirements if RoHS compliance is mandatory for the assembly process.

Memory IC Selection Notes

Select the appropriate speed grade based on system clock requirements: -5 for 200 MHz, -6 for 166 MHz, and -7 for 143 MHz. Consider the industrial temperature variant if operation below 0°C is necessary. Evaluate power consumption characteristics, particularly standby and active currents, against system thermal limits and battery life expectations.

Memory IC Part Context

This component belongs to the IS42S16100 series of 16-Mbit SDRAMs from ISSI. It utilizes a standard SDRAM interface protocol compatible with various microcontrollers and FPGAs. The device represents a mature technology solution for cost-sensitive applications requiring moderate density and high bandwidth performance.

Memory IC Replacement Considerations

Direct pin-to-pin replacements include other ISSI parts within the IS42S16100 family with matching speed grades and package types. Cross-manufacturer equivalents must be verified for identical timing parameters, voltage levels, and command set compatibility.
