The CY8C24493-24LTXI is an 8-bit PSoC1 microcontroller from Infineon's PSOC®1 CY8C24xxx family, built around the proprietary M8C core clocked at 24 MHz. It carries 32 KB of on-chip flash program memory and 2 KB of SRAM, which together support moderate firmware footprints and real-time data buffering in a single-chip mixed-signal design.
Peripherals and connectivity for mixed-signal control
On-chip peripherals include a low-voltage detect (LVD), power-on reset (POR), PWM generators, and a watchdog timer — enough to supervise a standalone controller without external supervisor ICs. The connectivity block provides I²C, SPI, and USB interfaces, so the part can serve as a USB-to-sensor bridge or communicate on a multi-drop sensor bus. A single 10-bit ADC channel handles analog inputs like temperature or pressure transducers.
36 I/O in a 48-QFN with exposed pad
The 48-VFQFN package (7x7 mm, 0.5 mm pitch) exposes 36 general-purpose I/O lines — enough to drive a small keypad-and-LCD interface or read a bank of limit switches.
Active production and compliance status
It is ROHS3 compliant, which avoids the REACH exemption conflicts that older ROHS variants sometimes trigger in EU-bound equipment. No pin-compatible second source is documented from another manufacturer, so the BOM line is single-sourced to Infineon's PSOC1 family.
