It packs 16 KB of Flash and 2 KB of RAM. ## 24 MHz — enough for touch, not for DSP The 24 MHz core speed is the first thing to check against your timing budget. It will poll a CapSense matrix or read a 10-bit ADC channel at a few kilohertz without breaking a sweat. But if you need FFTs, PID loops faster than a few hundred hertz, or bit-banged protocols at 1 MHz, this part runs out of headroom. The sibling CY8C4245LQI-483 runs at 48 MHz and adds 12-bit ADCs — that is the step-up if your loop count grows. ## 16 KB Flash / 2 KB RAM — fit the firmware first The 16 KB program memory and 2 KB RAM set a hard ceiling. A CapSense library plus a UART bootloader can eat half that Flash before you write any application code. Plan the firmware map early — if your state machine or lookup tables push past 10 KB, you are out of room. The RAM is tight enough that you will want to use byte-sized variables and avoid large buffers. For a simple touch-button panel or a LIN node, it works. For anything with a display framebuffer or a TCP/IP stack, look at the PSoC 6 family. ## CapSense and analog on-chip The CapSense block handles self- and mutual-capacitance touch sensing without external components. The 10-bit ADC is single-ended, one channel. ## Package and temperature grade The UFQFN with exposed pad (5x5 mm) is a compact surface-mount package. The -40°C to 85°C range covers industrial enclosures. ## Sourcing and lifecycle The CY8C4024LQI-S412 carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy notice, no successor — Infineon is still manufacturing this part for new designs.","metaTitle":"CY8C4024LQI-S412 PSOC 4 MCU, ARM Cortex-M0+, 24 MHz","metaDescription":"Infineon CY8C4024LQI-S412 PSOC 4 MCU: 32-bit ARM Cortex-M0+ at 24 MHz, 16 KB Flash, 2 KB RAM, CapSense, 27 I/O, -40 to 85°C, 32-QFN.
