Detailed Description for CY8C4124LQI-443
Product Overview
The Cypress Semiconductor Corp CY8C4124LQI-443 is a PSOC 4 CY8C4100 microcontroller built around a 32-bit ARM Cortex-M0 core. It combines 16 KB (16K x 8) FLASH program memory, 4K x 8 RAM, 34 I/O pins, and a 24 MHz internal oscillator. The device supports a 1.71 V to 5.5 V supply range and operates from -40°C to 85°C (TA). It is a surface-mount part in a 40-QFN (6x6) package with an exposed pad.
Key Features
- Cypress Semiconductor Corp CY8C4124LQI-443 uses a 32-bit ARM Cortex-M0 core with an internal oscillator and 24 MHz speed.
- Program memory is 16 KB (16K x 8) FLASH, and RAM size is 4K x 8.
- The supply voltage range is 1.71 V to 5.5 V, and the operating temperature range is -40°C to 85°C (TA).
- The device provides 34 I/O and supports I2C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, and UART/USART connectivity.
- Integrated peripherals include Brown-out Detect/Reset, CapSense, LCD, LVD, POR, PWM, and WDT.
- Analog functions include 8 x 12-bit SAR A/D converters and 2xIDAC D/A converters.
- The surface-mount package is 40-QFN (6x6), also described as 40-UFQFN Exposed Pad.
Applications
- Capacitive-touch control panels with LCD indication and serial communication.
- Embedded sensing and control using PWM, 12-bit SAR A/D, and 2xIDAC D/A functions.
- Protocol interface equipment using UART, I2C, SPI, IrDA, SmartCard, LINbus, Microwire, or SSP connections.
Design & Procurement Notes
Design teams should account for the 16 KB FLASH and 4K x 8 RAM limits when allocating firmware, buffers, and communication stacks. The 34 I/O pins and multiple interfaces require early pin mapping and review of shared peripheral functions. The 40-QFN (6x6) exposed-pad package requires appropriate land pattern, solder mask, and thermal relief decisions. The 1.71 V to 5.5 V supply range and -40°C to 85°C (TA) range should be checked against the final board power architecture and ambient conditions. Analog functions, including SAR ADC, IDAC, CapSense, and LCD, may require attention to trace routing, decoupling, and noise control. The exact part number CY8C4124LQI-443 and package designation should be used on drawings and bills of materials to avoid confusion with other CY8C4100 devices.
