CY8C24894-24LTXIT

Product Overview

The Infineon Technologies CY8C24894-24LTXIT is a PSOC™1 CY8C24xxx 8-bit microcontroller IC built around an M8C core and specified for 24 MHz operation. It provides 16KB (16K x 8) of FLASH program memory, 1K x 8 of RAM, and 50 I/O pins in a 56-QFN-EP (8x8) surface-mount package. The device includes I2C, SPI, UART/USART, and USB connectivity, along with POR, PWM, and WDT peripherals. Mixed-signal resources are A/D 47x14b and D/A 2x9b, and the microcontroller uses an internal oscillator. Its supply voltage range is 3V to 5.25V, with an operating temperature range of -40°C to 85°C (TA).

Design & Procurement Notes

Design considerations include matching the 3V to 5.25V supply range, allocating the 50 I/O pins, and verifying that the 16KB FLASH and 1K x 8 RAM meet code and data requirements. The 56-QFN-EP (8x8) exposed-pad package requires a surface-mount PCB footprint compatible with the 8x8 outline and exposed pad. The specified -40°C to 85°C (TA) range should be checked against the final environmental envelope. Interface choices can be planned around the integrated I2C, SPI, UART/USART, and USB peripherals, while mixed-signal designs can use the A/D 47x14b and D/A 2x9b resources. POR, PWM, and WDT functions should be incorporated into reset, control, and timing plans as required by the system.
