Infineon Technologies 5962F1120202QXA

Overview

5962F1120202QXA from Cypress Semiconductor is a radiation-hardened 72-Mbit QDR® II+ SRAM with RadStop™ technology, configured as 4 M × 18, operating at 250 MHz with DDR interfaces on independent read/write ports, 1.8 V core supply, and qualified for space-grade applications requiring latch-up immunity ≥120 MeV·cm²/mg at 125 °C.

For engineers reviewing the 5962F1120202QXA datasheet, 5962F1120202QXA pinout, 5962F1120202QXA application, or 5962F1120202QXA equivalent, this device serves high-reliability embedded memory needs in satellite command/data handling, radar signal processing, and onboard avionics where total ionizing dose tolerance (300 krad) and neutron fluence survivability (2.0 × 10¹⁴ n/cm²) are mission-critical.

Technical Context

The 5962F1120202QXA implements a synchronous pipelined QDR II+ architecture with fully independent read and write ports sharing a multiplexed address bus, enabling concurrent transactions without bus turnaround. It uses rising edges of dual K/K clocks for DDR data transfer at 500 MHz effective rate and integrates a delay-locked loop (DLL) to achieve 2-cycle read latency.

RadStop™ technology enables radiation hardening via proprietary process and layout techniques, delivering verified SEL immunity, low soft error rate (≤1 × 10⁻¹⁰ upsets/bit-day with SECDED), and operation across –55 °C to +125 °C under MIL-PRF-38535 Class Q screening.

FAQ

What is the maximum operating temperature range for 5962F1120202QXA?

The 5962F1120202QXA is screened and qualified for operation from –55 °C to +125 °C per MIL-PRF-38535 Class Q requirements. Electrical parameters are guaranteed across this full range, including AC timing, DC leakage, and radiation performance metrics such as latch-up immunity and soft error rate.

Does 5962F1120202QXA require external termination resistors?

No. The device integrates programmable on-die termination (ODT) controlled via ZQ pin and internal calibration circuitry. When ZQ is pulled high, dynamic impedance tuning aligns output drivers to 50 Ω (±10%) for HSTL-18 signaling, eliminating need for discrete termination networks.

How is the four-word burst sequence aligned to the clock?

Each read or write transaction initiates a fixed four-word burst starting at the addressed location. Words are output/input on successive rising edges of K/K, with the first word aligned to the same edge that latched the address - ensuring deterministic, zero-jitter burst timing essential for coherent signal processing.

Can 5962F1120202QXA be used without enabling the DLL?

Yes, but with timing penalty: DLL disable increases read latency from 2 cycles to 3 cycles and removes echo clock alignment accuracy. For systems requiring strict setup/hold margins at 250 MHz, DLL must be enabled; its use is mandatory for flight-critical timing compliance per the device's qualification test plan.
