CY8C4247AZI-L433T Cypress MCU

Features:

32-bit MCU Subsystem 

■ 48 MHz ARM Cortex-M0 CPU with single-cycle multiply 

■ Up to 256 kB of flash with Read Accelerator 

■ Up to 32 kB of SRAM 

■ DMA engine with 32 channels Programmable Analog 

■ Four opamps that operate in Deep Sleep mode at very low current levels 

■ Cypress-provided peripheral component library, user-defined state machines, and Verilog input Low Power 1.71 V to 5.5 V Operation 

■ 20-nA Stop Mode with GPIO pin wakeup 

■ Hibernate and Deep Sleep modes allow wakeup-time versus power trade-offs Capacitive Sensing 

■ Two Cypress Capacitive Sigma-Delta (CSD) blocks provide best-in-class SNR (>5:1) and water tolerance 

■ Cypress-supplied software component makes capacitive sensing design easy 

■ Automatic hardware tuning (SmartSense™) Segment LCD Drive 

■ LCD drive supported on any pin with up to a maximum of 64 outputs (common or segment) ■ Operates in Deep Sleep mode with 4 bits per pin memory
