CY8C20496A-24LQXI

8位微控制器 -MCU 1.71V-5.5V CapSense Plus

1.8 V Programmable CapSense® Controller  with SmartSense™ Auto-tuning  1–33 Buttons, 0–6 Sliders

PSoC® Functional Overview CY8C20496A-24LQXI

The CY8C20496A-24LQXI PSoC family consists of on-chip controller devices, which  are designed to replace multiple traditional microcontroller unit  (MCU)-based components with one, low cost single-chip  programmable component. A PSoC device includes  configurable analog and digital blocks, and programmable  interconnect. This architecture allows the user 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 are  included in a range of convenient pinouts.
