Core and memory sizing for mixed-signal control
The CY8C4248BZI-L489 is a PSOC 4 device built around a 48 MHz ARM Cortex-M0 core — a 32-bit single-core processor that balances throughput and power for sensor-fusion and real-time control loops.
Peripheral integration and analog front-end
On-chip peripherals include CANbus, USB, I²C, SPI, UART, and IrDA for wired connectivity, plus CapSense for touch interfaces and an LCD drive controller. The analog subsystem provides a 12-bit SAR ADC with 16 channels and a 4-channel 8-bit DAC — enough for closed-loop control of a few analog outputs without an external converter.
Package and board-level integration
The 124-VFBGA (9x9 mm) package with 98 GPIOs packs a high pin count into a small footprint.
