The analog blocks can be configured as ADCs (up to 14-bit Delta-Sigma), DACs (up to 9-bit), PGAs, comparators, and programmable filters. The digital blocks provide timers, counters, PWMs, UARTs, SPI, CRC, and PRS generators. This flexibility allows designers to create custom peripheral configurations that match application requirements without external components. The device features 16KB Flash, 256B SRAM, I2C up to 400kHz, CapSense touch support, and operates from 3.0V to 5.25V.","working_principle":"The CY8C27443 uses a block-based reconfigurable architecture where analog and digital functions are implemented by configuring PSoC blocks through registers. The 12 analog blocks are arranged in a 4-column by 3-row array; each continuous-time block can implement amplifiers, comparators, or DAC references, while each switched-capacitor block implements ADCs, DACs, or programmable filters. The 8 digital blocks are arranged in 2 rows of 4, each configurable as timers, counters, PWMs, CRC generators, or PRS generators. Blocks are interconnected through an analog mux bus and digital interconnect system, and connected to GPIO pins through pin-level routing. The M8C core executes from Flash at up to 24 MHz, accessing blocks and I\/O through memory-mapped registers. PSoC Designer IDE provides drag-and-drop configuration of all blocks and generates initialization code.","pin_description":"\n
