IS61LF102436A-7.5TQLI-TR

Memory IC Overview

The ISSI IS61LF102436A-7.5TQLI-TR is a 36Mb synchronous flow-through static RAM organized as 1M x 36 bits. It features a 7.5 ns clock access time and supports a maximum clock frequency of 117 MHz. The device operates with a VDD supply voltage range of 3.135V to 3.465V and an isolated VDDQ output buffer supply of 3.3V or 2.5V (±5%). It utilizes a 100-pin TQFP package, complies with RoHS standards, and includes lead-free construction.

Memory IC Feature Summary

• Synchronous architecture with registered address, data, and control inputs controlled by a positive-edge-triggered clock
• Internal self-timed write cycles initiated by the rising edge of the clock input
• Individual byte write control combined with global write capability for flexible data manipulation
• Integrated power management including auto power-down during deselect and a snooze mode for reduced-power standby

Memory IC Applications

• Communication systems requiring high-speed memory buffering
• Networking equipment utilizing burstable memory architectures
• Processor cache controller implementations

Memory IC Procurement Notes

Verify that the specific suffix 'TQLI' corresponds to the 100-pin TQFP lead-free industrial temperature variant (-40°C to +85°C) as listed in the official ordering information. Confirm the required VDDQ supply voltage configuration matches the datasheet specifications for the LF series before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 1M x 36 organization is required within a 100-pin surface-mount footprint. Ensure the system design accommodates the 3.3V core voltage and the dual-voltage I/O option (3.3V or 2.5V). Verify that the 117 MHz maximum operating frequency meets the target bus speed requirements.

Memory IC Part Context

This part belongs to the IS61LF/VF102436A family of high-speed synchronous SRAMs fabricated using advanced CMOS technology. The family integrates a 2-bit burst counter and high-drive outputs into a single monolithic circuit, designed specifically for applications demanding low latency and high throughput in communication and networking environments.

Memory IC Replacement Considerations

The IS61LF102436A-6.5TQLI offers a faster 6.5 ns access time within the same package and pinout. The IS61VF102436A-7.5TQLI provides equivalent performance but requires a fixed 2.5V supply voltage instead of the LF series' 3.3V/2.5V flexibility.

Memory IC FAQ

How is the burst sequence order determined?

The MODE pin selects the burst sequence; tying it LOW achieves linear burst, while tying it HIGH or leaving it floating achieves interleaved burst.

What is the function of the ZZ pin?

The ZZ pin enables the Snooze Mode, which reduces standby current consumption when the device is deselected.
