CY8C24123-24PI

Overview

The CY8C24123-24PI is an 8-bit microcontroller IC from the Infineon PSoC™1 family, utilizing the M8C core processor. It features 4KB of Flash program memory and 256 bytes of RAM. The device operates at a maximum clock speed of 24MHz with an internal oscillator. It supports a supply voltage range of 3V to 5.25V and includes two 14-bit analog-to-digital converters and two 9-bit digital-to-analog converters. Communication interfaces include I2C, SPI, and UART/USART. The component is housed in an 8-SOIC package and is rated for operation between -40°C and 85°C.

Feature Summary

• Integrates programmable mixed-signal array architecture allowing flexible configuration of digital and analog blocks.
• Includes supervisory ROM (SROM) providing built-in functions such as bootload and communication protocols.
• Features low-voltage detection (LVD), power-on reset (POR), pulse-width modulation (PWM), and watchdog timer (WDT) peripherals.

Applications

• Battery-powered portable devices requiring mixed-signal processing
• Industrial control systems utilizing analog sensor interfacing
• Consumer electronics employing capacitive sensing or display driving

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm silicon revision A compatibility if legacy support is required. Check RoHS compliance documentation as the part may not meet current environmental standards. Ensure proper handling procedures are followed given the surface-mount packaging type.

Selection Notes

Select this model when specific pin counts and mixed-signal capabilities align with design constraints. Compare against CY8C24223 or CY8C24423 variants if larger memory sizes are needed. Evaluate the 8-SOIC package dimensions against PCB layout requirements. Consider the internal oscillator accuracy for timing-sensitive applications.

Part Context
