50 MHz 8051 core — what the speed buys you
At 50 MHz, this 8051 core runs control loops, data acquisition sequences, and communication protocol stacks (I²C, SPI, UART) without stalling the analog peripherals. The DMA controller offloads data transfers, so the CPU can service CapSense scanning or LCD refresh in the background. For a touch-sensitive panel reading four analog channels and updating a segment LCD, the headroom is comfortable.
Industrial temperature grade and package
Rated for -40°C to 85°C ambient, the CY8C3246LTI-162T fits factory-floor controllers, outdoor telecom gear, and automotive cabin modules. The 48-QFN with exposed pad (7x7 mm) provides good thermal conduction to the PCB — useful when the on-chip ADC and CapSense are running continuously.
Lifecycle and sourcing reality
ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect.
