67 MHz Cortex-M3 with programmable analog
The CY8C5868AXI-LP032 is a PSoC 5 device built around a 32-bit ARM Cortex-M3 core clocked at 67 MHz. That clock rate, combined with the 256 KB flash and 64 KB SRAM, gives enough headroom for a control loop with moderate signal processing — think motor commutation or sensor fusion — without needing external memory. The supply range spans 1.71 V to 5.5 V. That wide window means you can run the MCU on the same 5 V rail as an industrial sensor or a small relay driver, skipping a dedicated regulator. The 62 GPIOs in the 100-TQFP package give enough pins to bring out a parallel LCD bus alongside a few serial interfaces.
On-chip analog and peripheral mix
The data-converter block includes a 20-bit delta-sigma ADC and two 12-bit SAR ADCs, plus four 8-bit DACs. That 20-bit converter is the headline — it resolves microvolt-level signals from a load cell or thermocouple without an external ADC. The CapSense block adds capacitive touch sensing, which is why this part shows up in human-machine interface panels. Connectivity covers I²C, SPI, UART/USART, USB, and LINbus. The USB peripheral is a full-speed device controller; the LINbus interface suits automotive body-electronics nodes. The 2 KB EEPROM stores calibration constants or boot parameters without wearing the flash.
Active production — sourcing posture
Sourced per RFQ against your BOM quantity — no stock-holding claim, but the supply channel is open.
