CY8C20234-12LKXI集成电路（IC）的微控制器规格书PDF中文资料

CY8C20234-12LKXI属于集成电路（IC）的微控制器。由赛普拉斯半导体公司制造生产的CY8C20234-12LKXI微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。

PSoC Functional Overview

The PSoC family consists of many Programmable System-on-Chips with On-Chip Controller devices. These devices are designed to replace multiple traditional MCU based system components with one low cost single chip programmable component. A PSoC device includes configurable analog and digital blocks and programmable interconnect. This architecture enables 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.
