For a typical CapSense or LIN-bus node, that split leaves enough headroom for the HAL and a small RTOS without squeezing the linker script. ## Peripheral set and analog front-end On-chip peripherals include CapSense for touch sensing, LCD drive, and a full set of brown-out/reset supervisors (Brown-out Detect/Reset, LVD, POR, WDT). The data converter section provides an 8-channel 12-bit SAR ADC and two IDAC outputs. The 12-bit SAR gives 4096 counts across the reference range — adequate for monitoring analog sensor inputs (thermistor, potentiometer, current shunt) at moderate update rates. The IDACs can source a programmable current for sensor excitation or closed-loop control. ## Package, footprint, and temperature grade Housed in a 40-UFQFN exposed-pad package (6x6 mm body, 40-QFN supplier device package), the part mounts on a standard surface-mount footprint. ## Lifecycle, compliance, and sourcing No official second-source or pin-compatible cross-reference is listed — the PSOC 4 family is a single-vendor architecture, so a BOM change would require a firmware port.","metaTitle":"CY8C4245LQI-483 Infineon PSOC 4 MCU, 48MHz, 32KB Flash","metaDescription":"CY8C4245LQI-483 ARM Cortex-M0 MCU, 48MHz, 32KB Flash, 4K x 8 RAM, 34 I/O, 40-QFN.
