Product details
Cypress Semiconductor Corp's CY8C4146FNI7-S433T delivers military-grade reliability in Embedded - Microcontrollers, developed for aerospace and defense applications where radiation tolerance and mission longevity are paramount.The ARM® Cortex®-M0+ core incorporates triple modular redundancy for SEU mitigation, achieving >99% single-event upset immunity in orbital radiation environments.A 32-Bit Single-Core architecture with parity-protected data paths prevents silent data corruption, meeting MIL-STD-883G requirements for spaceborne electronics.When operating at 48MHz, the microcontroller maintains timing accuracy within 0.01% despite temperature variations from -55 C to 125 C, critical for navigation systems.The I²C, IrDA, LINbus, SPI, UART/USART interfaces implement Manchester encoding for noise-immune data transmission, ensuring reliable communication in high-EMI environments like radar installations.Brown-out Detect/Reset, CapSense, LCD, POR, PWM, WDT include radiation-hardened timers and watchdog circuits that automatically recover from single-event functional interrupts within 10 s.64KB (64K x 8) of TMR-protected storage accommodates flight control algorithms with full error detection and correction capabilities.The FLASH implementation uses SONOS technology that withstands 300krad total ionizing dose, exceeding space qualification requirements.8K x 8 of scrubable memory prevents accumulation of single-event upsets, maintaining data integrity during extended missions in high-radiation orbits.The 1.71V ~ 5.5V range supports operation from unregulated spacecraft power buses with 100mV ripple, eliminating need for additional regulation stages.Qualified for -40°C ~ 85°C (TA), the device operates reliably in exoatmospheric conditions where thermal cycling extremes exceed commercial specifications.
