Overview
The CY8C4247AZI-L423 is a PSoC™ 4200L microcontroller based on the Arm® Cortex®-M0 CPU, operating at up to 48 MHz. It features 64 kB of Flash memory and 8 kB of SRAM. The device includes one 12-bit SAR ADC, four opamps, two low-power comparators, eight TCPWM blocks, four SCB modules, and USB Full-Speed capabilities. It supports up to 98 programmable GPIOs and offers multiple low-power modes including Stop, Deep Sleep, and Hibernate.
Feature Summary
- Integrates programmable analog and digital subsystems for flexible in-field tuning
- Supports capacitive sensing with automatic hardware tuning via SmartSense technology
- Provides segment LCD drive functionality on any pin with deep sleep support
- Includes secure expansion of memory off-chip and robust flash protection
Applications
- General-purpose embedded system controllers
- Smart sensing applications requiring capacitive touch interfaces
- Human machine interface designs utilizing segment LCD displays
- Industrial networking using CAN or serial communication protocols
Procurement Notes
Verify the specific ordering suffix L423 corresponds to the required package type and temperature range. Confirm that the 64 kB Flash variant meets application storage needs. Ensure compatibility with the PSoC Creator IDE for design implementation. Check for RoHS compliance status if required by regulatory standards.
Selection Notes
Select this model when 64 kB of program memory is sufficient compared to higher-capacity variants. Choose the VFBGA-124 package if high pin count density is required. Consider the ARM Cortex-M0 architecture for upward compatibility with M3/M4 codebases. Verify that the integrated USB and CAN peripherals align with connectivity requirements.
Part Context
This component belongs to the PSoC™ 4200L family, which combines an MCU with programmable logic and analog blocks. It is designed for scalability within the PSoC™ 4 platform, allowing migration to other members for expanded needs. The family emphasizes low power consumption and reconfigurable hardware architecture.
Replacement Considerations
Check for CY8C4247AZI-L423T tape-and-reel packaging equivalents. Review CY8C424x family datasheets for pin-compatible alternatives with different memory sizes. Ensure substitute parts maintain the same ARM Cortex-M0 core and peripheral set.
