What this 8-bit PSOC®1 MCU brings to the BOM
The Infineon CY8C21434-24LTXI is an 8-bit M8C-core microcontroller from the PSOC®1 CY8C21xxx family, clocked at 24 MHz. On-chip peripherals include POR, PWM, and WDT for basic housekeeping, plus I²C, SPI, and UART/USART serial interfaces for connecting to sensors, displays, or a host controller.
Supply voltage and power rail fit
Memory budget — what 8 KB Flash and 512 x 8 RAM can hold
8 KB of Flash and 512 x 8 bytes of RAM handle a dedicated control task with a serial stack and application code.
It is ROHS3 compliant. No last-time-buy or end-of-life notices are on file. For dual-sourcing resilience, the CY8C29466-24PVXI is a functional peer within the PSOC®1 M8C family — same core, same 24 MHz speed, same serial interfaces and POR/PWM/WDT peripherals — though it offers more memory and a different package.
