Infineon CY8C4146LQE-S423T: A Comprehensive Technical Overview

The Infineon CY8C4146LQE-S423T is a highly integrated, programmable embedded system-on-chip (SoC) belonging to the renowned PSoC 4 family. It represents a fusion of a microcontroller with the flexibility of programmable analog and digital peripherals, designed to reduce system component count, board space, and power consumption for a vast array of embedded applications.

At the heart of this device lies a powerful 32-bit Arm® Cortex®-M0+ CPU, operating at a frequency of up to 48 MHz. This core provides an efficient processing backbone, capable of handling complex control algorithms while maintaining low power consumption. The device is built on Infineon's unique PSoC® 4 architecture, which incorporates CapSense® technology for robust and reliable capacitive touch sensing interfaces, enabling the creation of modern, button-less human-machine interfaces (HMI).

A defining characteristic of the CY8C4146LQE-S423T is its rich set of configurable peripherals. The device features programmable analog blocks, including a 12-bit, 1-Msps SAR ADC with up to 12 channels, two opamps, and a low-power comparator. These allow designers to create custom analog front-ends (AFEs) tailored precisely to sensor interfacing needs. On the digital side, it includes programmable digital logic based on Universal Digital Blocks (UDBs), offering the flexibility to create custom peripherals like PWM, timers, counters, and UARTs, or even implement simple state machines without taxing the CPU.

Memory resources are ample for its class, with 64 KB of embedded Flash memory for application code and 8 KB of SRAM for data handling. The part number suffix 'LQE' specifies a 64-QFN package, making it suitable for space-constrained designs.

Key operational parameters highlight its versatility. It supports a wide voltage range from 1.71V to 5.5V, allowing direct battery operation and easy interfacing with various components. The operating temperature range of -40°C to +85°C ensures reliability in industrial and automotive environments. Furthermore, it offers multiple low-power modes, including Sleep, Deep Sleep, and Hibernate, making it an excellent choice for battery-powered and energy-harvesting applications.

Typical applications span across consumer electronics, industrial control, Internet of Things (IoT) nodes, automotive body electronics, and home appliances, wherever a combination of sensing, control, and user interface is required.
