INFINEON CY8C21234-24SXI 8 Bit MCU, PSOC1, PSOC 1 Family CY8C21x34 Series Microcontrollers, M8C, 24 MHz, 8 KB, 16 Pins, SOIC

The CY8C21234-24SXI is a 8-bit PSoC® Programmable System-on-Chip Microcontroller designed to replace multiple traditional MCU-based system components with a single-chip programmable component. A PSoC device includes configurable blocks of analogue and digital logic and programmable interconnect. This architecture allows you to create customized peripheral configurations, to match the requirements of each individual application. Additionally, a fast CPU, flash program memory, SRAM data memory and configurable I/O. The PSoC architecture consists of four main areas, the core, the system resources, the digital system and the analogue system. Configurable global bus resources allow the combining of all device resources into a complete custom system. Each PSoC device includes four digital blocks. Up to two analogue comparators and up to 16 GPIO are also included. The GPIO provide access to the global digital and analogue interconnects.
