概要

Description

CY8C5866LTI-LP022 is a Cypress (Infineon) PSoC 5LP mixed-signal microcontroller in a 22-pin LP package. It uses an ARM Cortex-M3 core and combines on-chip programmable analog and digital blocks (the PSoC fabric) with standard peripherals for flexible, configurable designs. Features typically include configurable ADC/DAC, op-amps and comparators, flexible digital blocks, DMA, timers, and serial interfaces (I2C, SPI, UART), plus low-power modes. It’s suited for embedded control, sensing, and compact systems requiring customized analog front-ends. For exact specifications—flash and RAM size, peripheral counts, and package details—refer to the CY8C5866LTI-LP022 datasheet and Infineon product page.

Features

CY8C5866LTI-LP022 is a PSoC 6 MCU with BLE. Notable features:
- Dual-core ARM Cortex-M4F and Cortex-M0+ with Arm TrustZone for secure tasks
- Bluetooth Low Energy radio (BLE) for wireless connectivity
- CapSense capacitive sensing for touch UI
- Programmable analog and digital blocks: ADCs, DACs, op-amps, comparators, and flexible digital blocks
- Cryptography hardware: AES, SHA, RNG, plus secure boot and secure isolation
- Rich peripherals: I2C, SPI, UART, USB 2.0 (FS), PWM, timers, I2S
- Flexible routing and programmable logic for custom peripherals
- Low-power operation with multiple power modes and deep-sleep support
- Wide I/O voltage range (typically 1.8V–3.3V) and multiple power domains
- Supported by Cypress/Infineon toolchains (PSoC Creator/ModusToolbox)
- Package: LP022 (compact 64-pin style) for space-constrained designs
Note: exact memory sizes, BLE version, and I/O counts can vary by revision; consult the datasheet for precise specifications.
