Overview
The CY8C4246AZQ-M443 is a PSoC 4200L microcontroller featuring an ARM Cortex-M0 core operating at 48 MHz. It integrates 64 kB of Flash memory, 8 kB of SRAM, and 8 kB of ROM. The device includes one 12-bit SAR ADC, two low-power comparators, four opamps, and eight TCPWM blocks. Communication interfaces consist of four SCBs supporting I2C, SPI, and UART protocols. It offers 38 GPIO pins in a TQFP-48 package, operates between 1.71 V and 5.5 V, and supports temperatures from -40°C to +105°C.
Feature Summary
- Integrates programmable analog and digital subsystems for flexible hardware configuration.
- Supports capacitive sensing with automatic hardware tuning capabilities.
- Enables direct segment LCD drive functionality on available pins.
- Provides multiple low-power modes including Stop, Deep Sleep, and Hibernate.
Applications
- Human-machine interface (HMI) controllers
- Industrial sensor nodes
- Battery-powered portable devices
Procurement Notes
Verify the specific suffix M443 against official Infineon documentation to confirm package type and temperature range. Ensure design compatibility with the TQFP-48 footprint and validate power supply requirements within the specified voltage limits before integration.
Selection Notes
Select this component when a balance of moderate processing speed and extensive analog/digital programmability is required. It is suitable for designs needing capacitive touch inputs or LCD displays without external drivers. Consider alternative pin counts if more general-purpose I/O is necessary.
Part Context
This part belongs to the PSoC 4200L family, which is optimized for low-power applications. It shares architectural similarities with other PSoC 4 devices but offers specific memory and peripheral configurations tailored for cost-sensitive embedded systems requiring mixed-signal capabilities.
Replacement Considerations
Check for CY8C4246AZQ-L443 for commercial temperature variants. Verify CY8C4246AXQ-M443 for different package options within the same performance tier.
