Infineon Technologies CY7S1049G30-10VXI

Overview

CY7S1049G30-10VXI from Infineon Technologies is a 4-Mbit (256K × 16) synchronous static RAM (SSRAM) with 3.3 V core/interface supply, 10 ns access time, and industrial temperature range (–40°C to +85°C), used in high-speed networking packet buffering and FPGA co-processor memory interfaces.

For engineers reviewing the CY7S1049G30-10VXI datasheet, CY7S1049G30-10VXI pinout, CY7S1049G30-10VXI application, or CY7S1049G30-10VXI equivalent, key selection criteria include access time consistency under burst read, low-power standby current, and compatibility with QDR-II/DDR2 controller timing margins.

Technical Context

This SSRAM implements a pipelined address/command interface synchronized to K/K# clocks, supporting single-cycle read/write operations with programmable burst length (1, 2, 4, or full-page). It uses a dual-port architecture with separate data input and output buses to eliminate bus turnaround delay.

Internal self-timed write cycles ensure reliable data capture without external write pulse width constraints, and on-chip termination resistors reduce signal reflection on high-speed data lines at 166 MHz operation.

Key Specifications

Pinout & Package

The CY7S1049G30-10VXI is housed in a 100-pin Thin Quad Flat Package (TQFP) with 0.5 mm pitch and exposed thermal pad. Pin assignments follow JEDEC standard SSRAM layout for pin-compatible migration from earlier Cypress/Infineon generations.

FAQ

What is the maximum operating frequency supported by CY7S1049G30-10VXI?

The device supports up to 166 MHz clock frequency, validated under industrial temperature conditions (–40°C to +85°C) and 3.3 V ±0.3 V supply. This corresponds to a 6 ns clock period, enabling full-page burst transfers at peak bandwidth without timing violations.

Does CY7S1049G30-10VXI require external termination resistors?

No. The part integrates on-die termination (ODT) on all DQ pins, configured automatically during read operations. External 50 Ω series resistors are unnecessary, reducing PCB layer count and improving signal integrity on high-speed traces.

Can CY7S1049G30-10VXI operate in asynchronous mode?

No. It is strictly a synchronous SRAM requiring differential K/K# clock inputs for all address, command, and data transfers. There is no provision for asynchronous address latching or static timing modes.

Is CY7S1049G30-10VXI pin-compatible with earlier CY7S1049G25 variants?

Yes. It maintains identical 100-pin TQFP footprint and pin function mapping with CY7S1049G25-10VXI, differing only in internal timing parameters and electrical characteristics optimized for 166 MHz operation.
