Infineon Technologies 5962F1120101QXA

Overview

5962F1120101QXA 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 5962F1120101QXA datasheet, 5962F1120101QXA pinout, 5962F1120101QXA application, or 5962F1120101QXA equivalent, this device supports high-bandwidth concurrent memory access in radiation-intensive environments such as satellite command/data handling, onboard avionics processors, and high-reliability military flight control systems.

Technical Context

The 5962F1120101QXA implements a synchronous pipelined QDR II+ architecture with physically separate read and write data paths, eliminating bus turnaround delays. It uses dual-edge clocking (K and K#) - addresses latched on rising edge for reads and falling edge for writes - enabling true concurrent R/W operations at 500 MT/s effective data rate.

RadStop™ technology provides verified single-event latch-up (SEL) immunity up to 120 MeV·cm²/mg and total ionizing dose tolerance of 300 krad(Si), validated per MIL-PRF-38535 Class V screening. The device integrates a delay-locked loop (DLL) for precise 2-cycle read latency and JTAG 1149.1 boundary-scan for testability in hermetic CCGA packaging.

FAQ

What is the maximum operating temperature range for 5962F1120101QXA?

The 5962F1120101QXA is screened and qualified for operation from –55 °C to +125 °C per MIL-PRF-38535 Class V requirements. Electrical parameters are guaranteed across this full range, including DLL functionality and timing margins, with thermal resistance (θ_JA) of 18.5 °C/W measured in standard CCGA mounting conditions.

Does 5962F1120101QXA require an external SECDED controller for soft-error mitigation?

Yes - while the device achieves ≤1 × 10⁻¹⁰ upsets/bit-day under heavy-ion irradiation *with* an external SECDED EDAC controller, it does not include on-die error correction. The QDR II+ architecture provides full data coherency but relies on system-level ECC implementation for functional safety compliance in mission-critical applications.

Can 5962F1120101QXA be used with standard commercial FPGAs?

Yes - its HSTL Class I inputs and variable-drive HSTL outputs are compatible with Xilinx Virtex-7, Kintex-Ultrascale+, and Intel Stratix V/VII FPGA memory interfaces. Layout requires controlled-impedance routing matched to 50 Ω differential pairs for K/K# and CQ/CQ#, and proper ZQ termination to 240 Ω.

Is JTAG boundary scan supported in all operating modes?

Yes - the IEEE 1149.1 TAP controller remains fully functional across all voltage and temperature conditions, including during power-up sequencing and standby. Test access is retained even when RPS/WPS are inactive, enabling in-system verification without interrupting memory operation.
