Meet the Infineon CY8C3866PVI 021, a cutting-edge 8 bit PSoC 3 microcontroller (PSoC® = Programmable System on Chip). Boasting a robust 8051 core clocked up to 67 MHz, 64 KB of reliable Flash memory, and 8 KB of SRAM, this SSOP 48 SMD powerhouse merges programmable analog, digital peripherals, flexible I/O routing, and communication interfaces—all in one compact, energy efficient package. It’s tailored to deliver high performance mixed signal control without inflating your board layout or development timeline.

Why Is the CY8C3866PVI-021 the Right Choice?

If you're looking for a future forward, integrated microcontroller that simplifies mixed signal designs, accelerates development, and saves real estate, the CY8C3866PVI 021 is the smart pick. Its unique PSoC architecture lets you tailor analog and digital blocks via software—slashing component counts and enabling agile firmware based refinements. With rich on chip peripherals, broad voltage range support (1.7–5.5 V), and industrial grade reliability, it delivers versatility and endurance. In short, it empowers engineers to design smarter, not harder.

Product Core Highlights – Features & Benefits

Single cycle 8051 core running up to 67 MHz—fast, legacy friendly processing power.
64 KB Flash memory (100 000 write cycles, 20 year data retention) for durable and secure firmware storage.
8 KB SRAM plus 2 KB EEPROM memory—ideal for data, configuration, and state retention.
Configurable analogue blocks, including ADC (up to 20-bit, 192 ksps), DACs, comparators, op amps, and CapSense—achieve tailored analogue signal processing on chip.
Digital building blocks (UDBs), DMA, LCD controller, PWM, WDT, POR—support complex logic, control flows, and interfaces without external components.
Flexible communication interfaces: I²C, SPI, UART/USART, LIN, USB, EBI/EMI, and optionally CAN—greatly simplifies connectivity across systems.
25 GPIO pins (up to 31 programmable I/O)—enables versatile pin assignments via software—minimising board redesigns.
Wide supply voltage range (1.7 V to 5.5 V) with multiple power modes—ideal for battery powered and energy sensitive designs.
