CY8C21434-24LTXI Description

Short technical summary and product information.

The Cypress Semiconductor CY8C21434-24LTXI is a PSoC Programmable System-on-Chip (PSoC) microcontroller based on a powerful Harvard-architecture M8C processor. It offers processor speeds up to 24 MHz, with an operating voltage range of 2.4 V to 5.25 V, and can operate down to 1.0 V using its on-chip switch mode pump. This device is designed for industrial temperature ranges from -40 °C to +85 °C.

Key features include 8 KB of flash program storage with 50,000 erase/write cycles and 512 bytes of SRAM data storage. It supports in-system serial programming (ISSP) and partial flash updates. The microcontroller is equipped with advanced peripherals, including four analog PSoC blocks with comparators and ADCs, and four digital PSoC blocks offering timers, counters, PWMs, CRC, PRS modules, and UART/SPI interfaces. All general purpose I/O (GPIO) pins are connectable to these blocks and feature 25 mA sink and 10 mA source drive capabilities.

Flexible on-chip memory and programmable pin configurations make this a versatile component for various embedded applications. The device also includes an I2C master/slave interface supporting speeds up to 400 kHz. Development is supported by free software tools like PSoC Designer.
