PSoC 5 with a 67 MHz Cortex-M3 — what this part brings to a BOM
The Infineon CY8C5468LTI-LP026 is a 32-bit ARM Cortex-M3 MCU from the PSoC 5 family, clocked at 67 MHz. It carries 256 KB of Flash program memory, 64K x 8 of SRAM, and 2K x 8 of EEPROM — enough room for a CapSense touch stack, a USB device stack, and a modest control loop without external memory. The 68-QFN package (8x8 mm) keeps the board footprint tight, and the 1.71 V to 5.5 V supply range means it can run off a single Li-ion cell or a 5 V industrial rail without a regulator swap.
CapSense, USB, and analog — the on-chip peripherals that save board space
This part integrates CapSense touch-sensing hardware, a full-speed USB 2.0 interface, and a 12-bit ADC plus two 8-bit DACs. For a touch-panel or appliance control board, that eliminates a separate touch controller and a USB PHY. The 38 available GPIOs are enough for a character LCD, a keypad matrix, and a few sensor inputs. The internal oscillator keeps the BOM simple — no external crystal needed unless you require precise USB timing.
