M8C core with USB 2.0 FS and 16 KB on-chip flash
The CY7C64215-28PVXCT is an enCoRe™ III series USB microcontroller from Infineon, built around the 8-bit M8C core. It integrates 16 KB of on-chip flash program memory and 1K x 8 of SRAM, targeting USB Full-Speed peripheral applications that need a single-chip controller with a proven, low-power architecture. The 22 general-purpose I/O lines, combined with a native USB 2.0 FS interface and a separate I²C port, let this part serve as the bridge between a USB host and a sensor array or control panel without an external PHY or protocol translator.
Supply range and temperature grade for commercial equipment
Operating from 3 V to 5.25 V, the part runs directly off a regulated 3.3 V rail or a 5 V USB bus supply — no extra level shifting on the Vdd pin. Housed in a 28-SSOP (5.30 mm body width, 0.209-inch pitch), the footprint is a standard 0.65 mm pitch SSOP. The 28-pin count leaves room for a USB D+/D- pair, an I²C bus, and up to 22 GPIOs on a two-layer board — no fine-pitch fan-out required.
